H R 11th Assem. Tuesday, January 1, 1839. Laid on the table, and 5,000 copies ordered to be printed t MESSAGE of THE GOVERNOR transmitting the REPORT OF THE BOARD OF COMMISSIONERS of the ILLINOIS AND MICHIGAN CANAL. to the LEGISLATURE OF ILLINOIS, DECEMBER 31, 1838. VAND ALIA: William Walters, Public Printer. 1839. MESSAGE. Executive Department, Vandalia, January 1, 1839. Sir : In compliance with a resolution of the House of Representa¬ tives, calling on this department for the report of the Board of Commis¬ sioners of the Illinois and Michigan canal, I have the honor herewith to transmit to you their report made to me in conformity to law, which I received on this morning, and which I respectfully request you tojay before the body over which you have the honor to preside. I am, sir, with high respect, Your obedient servant, THOMAS CARLIN. To the Hon. the Speaker of the House of Representatives. REPORT OF THE BOARD OF CANAL COMMISSIONERS. Canal Office, Lockport, Dec. 13, 1838» To his Excellency Thomas Carlin, Governor of Illinois. Sir : In obedience to the requisitions of law, the Board of Commission¬ ers of the Illinois and Michigan canal have the honor of transmitting to your Excellency the following ANNUAL REPORT. .t The transactions of the first Board, from its commencement of opera¬ tions to the close of the year 1836, were submitted to the Legislature in January, 1837; soon after which the law was materially amended, im¬ portant examinations were ordered, additional works were authorized, and the superintendence of the canal was committed to the charge of the present commissioners. At the called session, held in July of the same year, the new Board gave a full detail of their "acts and doings" to the first of June preced¬ ing. This report, therefore, as well to facilitate legislative action as to elucidate the subject clearly, will begin at that period and complete the chain of proceedings to the first of the current month. That the information, herein communicated; might be as satisfactory as possible, the principal engineer was instructed to spare no pains in report¬ ing the progress and condition of every class of construction—the im¬ provements effected in plans and locations—the suitability of stone and other material for structures—the character of excavations as now devel- 5 oped—the difficulties that have been obviated, and those yet to be encoun¬ tered—the probable sufficiency of contract prices—-and all other minutia in anywise appertaining to his department. He has discharged this duty with his usual frankness and ability, as will be seen by a recurrence to his report, marked A, which has been carefully examined, and was found to harmonize so fully with the opinions and observations of the commis¬ sioners as to render it unnecessary, on their part, to say much more on that branch of the subject. The documents, marked B, 0, and D, are reports from the resident en¬ gineers, made by order of the Board. They are intentionally more dif¬ fuse than those of the chief engineer, and are believed to be correct rep¬ resentations of the affairs of the respective divisions. In accordance with the fourteenth section of the canal law of 1836, the accounts of the Treasurer have been regularly collated with those of the O . Branch of the State Bank at Chicago, and their uniform agreement has been certified at the end of each quarter in the minutes of the Boardé His ample report, marked E, exhibits the present state of the Treasury—• the amount, time, and rate of loans—the interest paid and received by the canal fund—the receipts from the sales of towui lots, and how many of these lots have been forfeited by the purchasers. The Secretary of the Board, who, from the beginning, has acted as dis¬ bursing officer of the contingent fund, has discharged that arduous duty with accuracy and fidelity. His books, accounts and vouchers, like those of the Treasurer, have been examined and approved, from time to time, and are now in creditable order. An exposition of the business of his office, embraced in a report, marked F, will show—1st. The quarterly accounts of the Branch Bank at Chicago, since the last day of May, 1837. 2d. The amount of all moneys expended by order of the Board,, and the heads under which the expenditures have been charged. 3d. The accourt t of sales of lots at Lockport, Ottawa, and La Salle, with the valuation of each lot, and the sum for which it was sold. 4th. The work done, and the prices allowed for the various kinds of work. 5th. The contracts made, with whom made, and the security giyen. 6th. The number of eugineers, surveyors. draftsmen, clerks, and agents, of every description, permanently employed, their names and the compensation paid to each. 7th. The amount expended in provisions and materials to aid the con¬ tractors—the quantity of these provisions and materials distributed, and the cost of what remains in store. 8th. The amounts advanced to con¬ tractors in money and in materials, over and above their monthly esti¬ mates, and also the sums ultimately due to the same contractors in con¬ sequence of the regular deduction of fifteen per centum from the value of their work. Of the several items composing the Secretary's exposition, the six first enumerated contain such information only as the law specifically enjoins the commissioners to report. The two last have grown out of irregulari¬ ties forcéd upon the Board by the peculiar condition of the country and of the times. The operations upon the canal, during the whole of the year 1836, and the major part of the year 1837, were chiefly confined to pre¬ paratory work, such as building houses of accommodation for the laborers, procuring implements, making defences, erecting machinery, &c.; all of which required but few men ; and indeed very few had yet arrived in thé 6 country. But in the fall of the latter year laborers became more plenty, and the principal work was prosecuted with great vigor. It was soon as¬ certained, however, that the country was bare of many of the essential materials required by the contractors ; among which were iron and steel for manufacturing their tools and machinery, gun-powder for blasting rock, chains, and cordage for their pumps, cranes and railways, and staple provisions for the winter sustenance of their workmen. Derangement of business and heavy pecuniary sacrifices on the part of the contractors were the results of such a state of things ; besides which many of the la¬ borers were reluctantly compelled to abandon the line, and the contrac¬ tors, deprived of facilities, were unable to employ others, who were con¬ stantly coming in from Canada and the Eastern States. The evil was gen¬ erally acknowledged to be one of vital character. It dispirited the strong¬ est and most enterprising contractors, and was abundantly calculated to suppress responsible propositions for the remainder of the work, unless at prices large enough to cover all the actual, and many alleged disadvan¬ tages. Nor was there any reasonable prospect of an early remedy ex¬ cept through the interference of the commissioners. The contractors were evidently too weak in capital to avail themselves of the proper time of the year for accumulating sufficient quantities of indispensable supplies; the Bank, if willing, was not in a condition to afford relief; and a reliance upon merchants in so new and remote a country was not only precarious, but calculated to invite monopoly and consequently extortion. It may be safely advanced that, on works of magnitude, be the contract prices ever so low, the employer will eventually have to pay whatever it cost the con¬ tractors to execute their work; for it is known that they are rarely if ever able to finish extensive jobs by which they are to lose. They cannot long support themselves without adequate compensation. As soon as they foresee a loss they are almost sure to abandon at all hazards; and work un¬ der such circumstances is apt to be relet on disadvantageous terms to the State. Every thing therefore that is done to save contractors from losses and delays, that can be averted, will, to the same extent, promote the inter¬ ests of the'public. Taking these facts and conclusions into view it was obvious to the commissioners that the contractors must be aided, for awhile, beyond the monthly regular payments from wffieh fifteen per centum was to be deducted. Accordingly, at the commencement of the last season, the Board complied with the general request of the contrac¬ tors to furnish them with such provisions and materials as could not be readily purchased in the country; each contractor binding himself in writ¬ ing to secure the State against loss by insurance, interest, transportation, or any contingency, and to pay for the articles as fast as he consumed them, out of his monthly estimates, if required by the Board. A ware¬ house was built for the purpose, on State property, at Lockport, and, so planned and positioned that while it increased the value of the surround¬ ing property not yet brought into market, it will at any time command a profit on its cost. Table No. 6, annexed to the Secretary's report, shows the amount of capital now involved in the transaction to be $36,917 74, and table No. 7 exhibits the extent to which aid has been afforded, and the ample security on which it is based. Experience has proved the utili¬ ty of the measure, bôth in supporting the old contractors and in obtain¬ ing new ones on reasonable terms. Full supplies are now maintained at 7 fair and uniform prices, encouraging the contractor to proceed with con¬ fidence, and enabling him to make better outfits and to do more work with the same capital and manual fpree. On the 13th day of November, 1837, the sealed proposals for work, advertised to be let on that day, were opened, and contracts were entered into for the remaining sections on the summit and lower divisions, togeth¬ er with the Fox river feeder, dam and guard-lock. Another public letting was held on the 5th day of June last, which resulted in contracts for twenty-one miles of that portion of the middle division lying between Lockport and Dresden, including structures of every description. The structures of the lower division were let at the same time. It frequently happens in such cases, as it did in these, that several contractors to whom work was awarded failed to commence in proper time; and some, not be¬ ing able to command capital, threw up their jobs; but the vacancies have been subsequently filled at prices as low as could be desired. The line is now under contract from the Chicago river to the termination at La Salle, with the exception of about twenty-two miles of shallow cutting between Dresden and Marseilles, and some other detached parts, amounting by es¬ timate to $1,251,103 15, and a mile and a fraction of excavation in the Saganaskee swamp, which, from the peculiar character of the work, as described in the report of the chief engineer, must either be executed in part by agents of the State, or wholly deferred until it can be drained through a series of sections below it. To avert the delay incident to the latter course, the first has been adopted, with orders for the immediate preparation of appropriate machinery . Efforts will be made to have eve¬ ry thing ready for a commencement by the breaking up of winter. It was once thought that no subdivision of equal length would cost as much or present as many difficulties as the one which stretches through this fa¬ mous swamp. The semi-fluid alluvion and vegetable matter, of which the swamp is mostly constituted, are not more forbidding in their aspect than they are treacherous in their texture. Hence for nearly two years it was impracticable at any season, by any mode, to penetrate it so tho¬ roughly as to ascertain with certainty its true depth and character. The hard freeze of last winter and the low stage of the river and bordering morasses enabled the resident engineer, with a strong party, to traverse and sound every part of them. It was found that the Des Plaines could be safely turned into its ancient channel behind a low island about a mile in length, redeeming by "the process some three or four hundred acres of canal land, and securing to the State an important town site which, by any other arrangement, would have fallen on individual property, Con¬ vinced of the practicability of turning and dyking the river, and that the flood waters of the Saganaskee valley could be diverted into the Oala- mic, there was no further hesitation in cancelling the contracts on tfie original circuitous route, and locating a direct line costing upwards of a hundred and twenty thousand dollars less, and possessing other obvious advantages independent of the town site, which at no remote period must be worth a large sum of money. Fdr details, see reports of the principal and resident engineers. , ' ? In making contracts on the summit division, previous to December, 1836, distinct prices were allowed for "solid rock" and "for rock which in the opinion of the chief engineer may he quarried" This distinction arose 8 in necessity. When the first letting was held in Chicago in June, 1836, the commissioners, prompted by policy and public opinion, were com¬ pelled to make an experimental letting of a portion of the heavy work without strict regard to its true value. Among the many proposals that were submitted at the time, there were but few from experienced con¬ tractors, or such men as could be trusted with difficult undertakings ; and these, at that early period, with nothing to guide their judgments but a rapid and superficial examination of the country, were reluctant to act upon the assertions of the commissioners and engineers, that the rock to be excavated was wholly stratified. They admitted that the indications were in favor of that position, but urged that "solid rock" might probably be encountered towards the bottom of the deep cutting; and, if so, that much higher prices must be allowed than those at which they were willing to take the "quarried rock." * The issue was, that the. accepted proposals and, of course, the contracts embraced both classes. But the commission¬ ers continued so firm in their first impressions, that they disregarded ex¬ travagant bids for "solid rock" whenever the same proposal contained a reasonable price for "rock which in the opinion of the chief engineer may be quarried;" and especially as the umpire would be a State agent, and probably the same who had repeatedly advised the Board that the admis ¬ sion of the contingency in question would involve 110 serious danger. Through the remainder of that year many sections were opened to various depths, yet no earnest demands for solid rock compensation were preferred until just before the meeting of the General Assembly. Those that were then made were promptly resisted, and the petitioners, threat¬ ening to appeal to the Legislature, were unsuccessfully encouraged by the commissioners to pursue that course. It will be remembered that during the session alluded to, a resolution was adopted by the House of Repre¬ sentatives ordering an investigation into the affairs of the canal. The committee, to whom the subject was referred, made, among others of a like tendency, the following comment on the estimates of the chief engi¬ neer. "It will be perceived that the item of rock excavation has been estimated as coming within the denomination of quarried rock, whereas all the information which your committee has been enabled to obtain upon that subject, tends to show conclusively that at least two-thirds of the item will fall under the class of solid rock excavation. If this be the fact, and that it is has been proved to the satisfaction of the,committee, the whole amount, as estimated by the engineer, must be greatly enhanced. By reference to contracts already let as solid rock excavation, it will be discovered that the average price is nearly $2 55. Assuming this sum, then, as the price for solid rock excavation, and computing two-thirds of the whole amount of rock excavation at about $2 55, the price for solid rock excavation, and the remaining one-third at $1 55, the price per cu¬ bic yard for quarried rock excavation, and the sum total for lock excavation on this division is found to exceed the estimate of the engineer, $2,050,- 800; by which it appears that the item of rock excavation alone amounts to $6,814,331. But admitting the whole item to fall under the denomin¬ ation of quarried rock, it is believed that contractors coul^ not be procur¬ ed to excavate t.hp same at prices less than those allowed for solid rock, on account of the great elevation to which it would have to be raised, after 9 being quarried, to remove it from the works, A moment's reflection will show the truth of this view of the subject." These opinions, it is believed, emanating as they did from a high source, stimulated some of the contractors to insist with pertinacity upon an im¬ mediate allowance for "solid rock." Others, who made no present claim, spoke freely of their intentions to contest the matter upon the completion of their work; and it was ascertained by the Board that some of. the par¬ ties, encouraged by able counsel, were actually making preparations to fortify their position. In view of all these circumstances, and knowing at the same time the uncertainty ot legal decisions, the commissioners were forced to believe that,however unjust the claims, there was imminent danger in permitting the contractors to finish their work, under the exist¬ ing contracts, if it were possible to prevent it without violating the faith and dignity of the State. It was therefore resolved that jvhile the contrac¬ tor, in disregard of equity, insisted upon every advantage which he could obtain by law, the commissioners would be equally rigid in ruling him to the letter of his contract; and accordingly the chief engineer was in¬ structed to issue his certificate of abandonment, in every case, on the first clear provocation. Some had already violated their contracts by selling them and giving irrevocable letters of attorney, setting forth a valuable consideration ; others had failed to commence and prosecute their work in accordance with the reasonable requisitions of the superintending engi¬ neer; and it was extremely doubtful whether any of them could complete their jobs within the time specified in their respective articles of agree¬ ment. Thus situated, and being apprised of the determination of the Board to coerce justice if any longer denied, they were gradually induced to relinquish their disputed contracts and enter into new ones based upon the former prices for "quarried rock," with slight additions in such cases as experience had shown were originally taken at too low a rate. The final settlement of this vexed question is highly advantageous to both par¬ ties. The contractor is placed upon a footing which leaves no doubt of his ability to finish his work ; and the State, besides avoiding hazardous and expensive litigation, can now estimate with certainty the ultimate cost of her great enterprise. In the quarterly report of the Board, transmitted to the General Assem¬ bly in July, 1837, it was stated that a correspondence had been opened with Judge Wright, an eminently "skilful engineer," with a view to the surveys and examinations required by the third section of the amen¬ datory canal law passed in the previous March. In the meantime, Mr. Burnett, who is now the resident engineer of the third division, was in¬ structed to make a critical and thorough survey of the dividing ridge between the Fox and Des Plaines rivers, and "within the limits of the State." This duty he performed with great care, eliciting information from every accessible source, and indulging those persons who desired explora¬ tions of particular depressions previously supposed and asserted to be sufficiently low to afford a cheap feeder. Judge Wright arrived at Chicago in the early part of October, and on the 20th of the same month, Mr. Burnett made a detailed report, with a topographical map and estimates, of the quantities of excavation and other work necessary to effect the object on the most favorable route of which the country was susceptible. At that time and through the whole 10 summer, the Des Plaines river was generally admitted to t>e unusually flush, as was also the Calamie. No gauges were therefore ordered, and consequently those of the Des Plaines, made by the United States' engi¬ neers in 1830, and of the Calamie, by Mr. Bueklin, were adopted as the basis of the investigation. Keeping in view, however, that the truth of these gauges had been strenuously controverted by the advocates of the upper lu v A or "shallow cut," and that the capacity of the Calamie had been contended to be even superabundant, the attention of the examin¬ ing engineer was particularly directed to the question, whether the Calamie could in any event be classed among waters which the law contemplated as 4sources within the legitimate authority of the State of Illinois a question which his reputation for sound judgment in every thing connec¬ ted with canaling, his knowledge of the requirements of Indiana depen¬ dant on the Calamie, and his great experience in the adjustment of similar claims, pre-eminently fitted him to answer with confidence. His plain, free, and very decided report, marked G, to which Mr. Burnett's is appen¬ ded, will afford all the information required by the statute which enjoin¬ ed the examinations. But notwithstanding the opinion of the Commis¬ sioners, that the report of Judge Wright-—so completely confirming their original plan—should alone determine the mode of feeding the canal, they still thought it advisable to seize the first opportunity of reguaging the summit streams and examining the suitability of the country for sustain¬ ing assistant reservoirs. , The past dry season rendered the measuring of the Des Plaines almost unnecessary, since for nearly four months the tightest dam that could be erected, would not, at the point for taking out a feeder, have saved water enough to propel a single pair of ordinary mill-stones. Repeated guagings from the 20th of July to the 22d of Au¬ gust, and it wras afterwards still lower, gave an average of less than the measurement of 1830. The Calamie was guaged on the 8th of August, and again on the 21st of September, by Mr. Talcott, the competent and indefatigable resident engineer of the summit division, under the superin¬ tendence of the chief engineer and two of the commissioners, who assist¬ ed in the operation. Every precaution was taken to render the measure¬ ments perfect, but owing to the high stage of water in the lake which flowed back upon the only point adapted to the purpose, and the quantity of grass that had recently grown up in the bed of the river, it was im¬ practicable to compute the velocity of the current from top to bottom with all the precision that was desirable. Averaging the different guages, which are believed to be over the truth, the quantity estimated was a fraction less than 7,000 cubic feet' per minute, being only 1,600 feet more than reported by Mr. Bueklin, but falling short 10,217 cubic feet per minute of Mr. Belin's estimate as given in the printed report. The inference is fair, therefore, that Mr. Bueklin was right, and conclusive that Mr. Bèlin was either wrong in his calculation-, or, which is more probable, that the error was typographical. It is proper to mention also that the volume of water continued to decline for some weeks after the last guaging by Mr. Gooding and Mr. Talcott, but the general sickness of the. country prevented a repetition of their experiments. An attempt was made on the 8th of October, when it was found that the river had fallen two inches since the last and lowest previous guage, but the mea¬ surement was carried no further. In regard to reservoirs, it is sufficient Il to say that, besides their pernicious influence upon the health of such a country, it is believed that they could have rendered but little aid in a protracted drought like the one just experienced. in addition to the services required by law, the commissioners availed themselves of the valuable talents of Judge Wright in general consulta¬ tion. Tie was employed to inspect the entire line, and invited to criticise freely any and every part of the work in progress, as well as the plans of the chief engineer and of the Board, all of which were detailed to him on the ground with great minuteness. A number of written inter¬ rogatories were likewise propounded to him embracing every subject com¬ mented upon by the committee on Roads and Canals, in their report to the House of Representatives at the same session in which the examina¬ tion was ordered. The report itself had attracted his attention before he arrived in the State. The answers to these interrogatories, and the result of the general inspection are embodied in a separate report to the Board, marked H; by which it will be seen that the present plan of the canal, being the same originally adopted, has received the deliberate sanction of one of the ablest, most experienced, and most distinguished engineers of the age. Nor was that sanction given until after the most patient scrutiny both of the plan itself, practically examined, and of all the published discussions and animadversions on the subject. Since that report was obtained, the operations of another year, wide and varied in their range, develope nothing but additional confirmation. The fifteen sections extending from Chicago river to the "Point of Oaks," eight miles, and lying through the low wet prairie pèriodically flooded by the Des Plaines river through Mud lake, have been completely defended against any possible danger from surface water ; and are now, by means of those defences, accessible and tenable at any season of the year. The same plan, of drainage and defence is gradually progressing from the " Point of Oaks " to the Saganaskee swamp, and enough has been done to inspire the fullest confidence in the practicability and moderate cost of the work. Much less rock will be encountered than was once supposed, but the earth excavation will in some few instances cost a shade more than the estimates. The quantity of water to be pumped is not greater on an average than was anticipated ; although there are several sections that will require stronger machinery for that purpose than the others. The same remarks will apply to the rock cuttings between the Saganaskee and Lockport, all of which have been' permanently de¬ fended, and many of them so far advanced as to exhibit to the bottom every variety of material and every difficulty of excavation. Through Lockport and thence through Juliet, jnany improvements have^been made in the line. Symmetry and strength have been added ; the value of the water-power exclusively belonging to the State has been much increased; and every advantage that plans and locations could secure to the State has been scrupulously observed. The revenue from the sales of lots and water privileges in and between these flourishing towns must ultimately be very large, as will also be the case at the pas¬ sage of the Du Page river, where a manufacturing place of no little im¬ portance must /soon be required to meet the exigencies of the coun¬ try. , The costly and exposed sections around the base of the Kankakee 12 bluffs are in the hands of experienced contractors, who are known to have executed extensive and more difficult iobs on the St. Lawrence canal, •j The safety of the plan of construction is now generally conceded, and the prices at which the work was taken axe fair. From this point to Marseilles nothing has been let ; thence to Ottawa the work is advanc¬ ing steadily, and will be finished in good time. The navigable feeder from the Fox river, commencing at Green's mills and falling into the main canal at the town of Ottawa, and also a lateral canal and basin extending to the Illinois river, authorized in March, 1837, have been located with due regard to the enhanced value of the property of the State. The entire feeder, about five miles long, and a considera¬ ble section of the side cut have been placed under contract, and will probably be so far adyanced in another year as to render available the large and valuable water-power thus to be introduced into the heart of the town. These judicious improvements, ôrdered at the last regular ses¬ sion of the Legislature, cannot fail to advance the prosperity of Ottawa in a high degree. Strengthened and cultivated as her natural advantages now are, it is admitted by all intelligent observers that she must soon become an important manufacturing city, creating a vast amount of busi¬ ness for the canal, diffusing incalculable benefits through an extensive scope of country, and remunerating the State, by increased value of prop¬ erty, more than threefold the amount of the additional expenditures. Several mill sites might now be profitably sold at Juliet, where they are much needed for general convenience, but the Board have no authority to sell or lease such privileges on any part of the line. The power is in¬ dispensably necessary, and should be conferred on the commissioners or some other agents at the present session of the General Assembly. From Ottawa to the termination of the canal at the city of La Salle, the work, except the basin and steamboat channel, is progressing as rapid¬ ly as was expected. Several sections have been received, and many others will be ready for delivery early in the coming year. The chan¬ nel and basin will be pushed with vigor on the opening of the next season, and, if labor can be commanded, they will be in time for the remainder of the third division, which it is believed may be brought into use in the spring of 1841. The principal part of the aqueducts, locks, dams, and culverts of the middle and lower divisions, have been undertaken by practical mechanics, skilled and experienced in their line of business ; and, at the instance of Judge Wright and Mr. Gooding, a superintendent of established reputa¬ tion has been employed by the Board to keep a vigilant watch, and see that the laying of every stone is in accordance with the specifications of the contract. By this means uniform and permanent structures may be expected. Good stone, conveniently situated and carefully tested, has been found in sufficient abundance; and water lime or Roman cement, of the most superior quality, lies in inexhaustible beds scattered along the line from Lockport to the Little Vermilion river. An improved furnance for calcin- i ng and a steam-mill for grinding the lime, will soon be put in operation at Lockport, by Messrs. Norton and Steele, a firm from Canada, who manufactured principally for the St. Lawrence canals, while under the control of Judge Wright. The commissioners have contracted with 13 these gentlemen for a supply of the article at fifty cents per bushel, de¬ liverable at the respective structures, and subject to * the inspection of State agents—terms believed to be unusually favorable. The fourth section of the canal law of 1837, requires the Board of Commissioners to cause a survey and estimates to be made, as soon as con¬ venient, of the route of a canal diverging from the main trunk, through, the Saganaskee swamp and Grassy lake, to intersect the Caiamic river at the nearest practicable point, and to construct the proposed branch when¬ ever the State of Indiana' shall have undertaken a corresponding work connecting her system of internal improvements with the Illinois and Michigan canal. In compliance with this requisition, a party, under the direction of Mr. Burnett, was ordered to that duty as early as prepara¬ tions could be made. The season being one of extraordinary wetness, examinations and estimates could not be as accurately made as it was desirable they should be. But the commissioners, accompanied by the chief engineer, continued to explore the route until they ' realized their anticipations of the facility and cheapness with which an excellent canal might be constructed, uniting at once great public convenience and utility with a profitable investment of capital. Completed at a cost of not more than three hundred thousand dollars, it will connect the Illinois and Michigan canal directly with Lake Erie and all the artificial naviga¬ tion of Indiana and Ohio ; and it is thought that the[water-power, together with the town which it will create on State property, will more than reimburse the outlay. For the particulars of the survey, see Mr. Bur¬ nett's report, marked J. Major Lewis, one of the acting commissioners,, and Mr. Williams, the chief engineer of the Indiana canals, have verbally expressed their opinions to this Board, that Indiana would certainly ac¬ cept the invitation of the State of Illinois, and meet her at the dividing line ; but, as yet, no Written communication^ have been enterchanged. It is highly probable, however, that some step will be taken by Indiana, at the present session of her Legislature, which may demand immediate action, on the part of this State. It is therefore proper to inquire whether the existing laws confer the power on the Board of Commissioners to com¬ mence the prosecution of the work. It will be perceived that the fourth section of the amendatory act for the construction of the Illinois and Michigan canal, approved March 2d, 1827, after authorizing a survey and estimates, uses the following words : "the said work to be constructed whenever the State of Indiana shall undertake a corresponding work con¬ necting her system of internal improvements with the Illinois and Michi¬ gan canal." The work is ordered to be constructed, but the ways and means are not pointed out. No doubts are entertained that the power was intended to be conferred, and that it was designed to appropriate the necessary means out of the canal fund ; but the sixth section of the law of January 9th, 1836, says : "the money borrowed, the premiums arising from the sale of any stock created, the proceeds of the canal lands and town lots, and all the moneys in any way arising fropt the contemplated canal, shall constitute the canal fund,and shall be used for canal purposes, and for no other whatever, until the said canal shall have been completed." The words, 6 for canal purposes," taken with the context, would seem to mean, for the purposes of the Illinois and Michigan Canal. If so, a more explicit appropriation should be made. 14 The enlargement of the natural basin at the confluence of the north and south branches of the Chicago river, authorized by the 7th section of the law of 1837, will be commenced sometime during the approaching summer, unless a scarcity of labor should cause other work to be delayed by the commencement of that. The exchange of block number 14, the \ property of the State, for block number 7, belonging to individuals, has not been effected ; and it is the opinion of the commissioners that it will be decidedly to the interest of the canal fund to condemn block number 7, for removal, and sell fourteen, after the basin shall have been en¬ larged. The three commissioners appointed by the circuit judge of the seventh judicial district to value private property, required for the construction of the canal, have attended, at the instance of the Board, on two occasions. At their first meeting all were present, but at the second only two appear¬ ed, when it was contended by counsel, and sustained by the court, that thé law made no provision for any number less than three to act. The death of one of them occurred soon afterwards, and application being made by the claimant for the appointment of another, the judge decided that no power was anywhere vested for filling vacancies. These defects in the statute should be removed by amendment. The agents for the protection of canal lands have been less successful than was reasonably expected. Depredations, though not so frequent as formerly, continue to be committed with shameful impunity, arising in some degree, from the difficulties of obtaining such evidence as will satis¬ fy a jury. Some few judgments have been obtained at considerable cost, but chiefly against irresponsible persons. The commissioners continue of opinion, however, that the agency has been beneficial far beyond its ex¬ pense. Firm and vigilant men may yet arrest the lawless and dishonest practice of plundering lands devoted to so great an object ; and this belief finds strength in the good effects which were produced by the activity and fearlessness of Col. William Weatherford during his short period of service. It is nevertheless due to a large a respectable portion of the in¬ habitants of that section of country to say that public sentiment has under¬ gone and is undergoing a wholesome change in respect to the propriety of enforcing the laws against all trespassers. If the agents do their duty, they will find many influential citizens who are ready to aid and support them. Such assurances have repeatedly been made to the Board by per¬ sons in whom every confidence jan be reposed. The act, passed in July, 1837, providing conditionally for the sale of canal "lands to the ampunt of four hundred thousand dollars, made it the duty of the commissioners to select the lands intended to be sold—-to sub¬ divide them into lots of not less than forty nor more than eighty acres— and to value them in reference to many considerations. To comply with these injunctions, it became necessary to employ agents of suitable quali¬ fications for the collection of proper information. Mr. Richard G. Murphy, of Perry county, and Col. John Flemming, of Shelby, were invited to un¬ dertake the laborious task; and it affords the Board much pleasure to be able to say that, as far as these gentlemen progressed, they performed the duties assigned them with unremitting industry and much skill. Attended 1 by Mr. Preston, an excellent surveyor, they examined minutely, and in regular order, each section of canal land» establishing its corners and taking 15 tabular notes of the quality of soil—the quantity and description of tim¬ ber—the size and character of streams—the amount of improvements, if any—the location of those improvements—and many other items of in¬ formation highly useful for present and future purposes. A correct knowl¬ edge of these things was deemed indispensable to the Board, in order not only to select the lots to be offered, and graduate their value generally, but to guard against being overreached in selling an extraordinary tract of land for an ordinary price. It is to be regretted that the party was dis¬ persed by sickness before the object was accomplished; but the work will be resumed and finished as early as it can be economically done ; and if the pecuniary condition of the people will justify it, the lands authorized to be sold, or a part of them, will be brought into market in June or July. The sixth section of the act of March 2d, 1837, empowers the Board of Commissioners to sell such parts of the canal lands in the township in which Chicago is situated, and alternate lots in La Salle and other towns along the canal route, as might be necessary to produce the sum of one million of dollars. Under this authority, and since the last session of the Legislature, a few alternate lots have fyeen sold in Lockport, in Ottawa, and in La Salle, but more with a view of founding the towns and pre¬ venting individual property froni superceding that of the State, than for purposes of present revenue. The financial embarrassments of the Union for nearly the last two years will satisfactorily account for no other prop¬ erty being sold. The sales at the places enumerated, amounting in gross to $35,400, were effected at liberal prices considering the times, and al¬ most exclusively to actual settlers who are making substantial improve¬ ments. The Treasurer's and Secretary's reports contain specific accounts of sales. This rapid review of the condition of the canal and the affairs connec¬ ted with it, taken alone, would probably be thought, insufficient ; but in conjunction with the appended reports from the Treasurer and Secretary, and from the principal, the resident, and the examining engineers, it wilLbe found to embrace as much as could be said on the subject without repeating information which others had detailed with perspicuity. It appears from the estimates of the chief engineer, as will be seen by an examination of his report, dhat according to the contracts made, adding a full allowance for the light sections not under contract, the sum of $7,621,442 57 will cover; with very little variation, every expense for a convenient, substantial, and élégant canal, such as it ought to be for commercial economy, durability, and State character. The original estimate of the same engineer, exclusive of the additions at Ottawa and the enlargement of the basin in Chicago, was $8,654,337 51, being $1,032,- 894 94 more than will be required to complete the work. Upon a result so important to the people, and, under all the circum¬ stances, so gratifying to the Board, the Commissioners cannot refrain from tendering to your Excellency their warmest congratulations. It is the deliberate opinion of the Board that the canal may be finished in four years, if there be no delay on account of funds. The money al¬ ready consumed amounts to $1,432,445 43, of which $986,355 85 were disbursed in the last year; and but for the well known awful visitation of Providence, this sum would have risen to $1,200,000. The operations 16 for the year 1839 will require an additional appropriation of a million and a half of dollars, and those for 1840, two millions. A small part of these sums may possibly be derived from sales and collections, but to rely on that source beyond the interest to be paid on loans, would be a ques¬ tionable policy. In conclusion, the commissioners reiterate the opinion, expressed in the first annual report to the Governor, that "if these lands and town lots be very gradually and cautiously brought into > market, reserving the chief part until the canal shall have been completed, and all its advantages clearly understood, there is more than enough to build it on the present capacious and permanent plan. But, on the contrary, if sales be forced and all the lands be disposed of before their true value be known, there cannot fail to be a deficit of several millions of dollars. Many tracts of land, that would not bring more than five or six dollars per acre if sold immediately, may be worth, a few years hence, from twenty to one hun¬ dred dollars. Innumerable instances of the kind might be adduced, some of them iri the yicinity of the canal." All of which is respectfully submitted, W. F. THORNTON, Late President. JACOB FRY, Acting Commissioners Canal Office, Locfcport, December 10, 1S38. To the Board of Commissioners of the Illinois and Michigan Canal. Gentlemen : In pursuance of the duties assigned me, I have the honor to submit the following report. Since my last annual report to your Board, (à copy of which accom¬ panies this,) the work upon the canal has progressed with as much rapidi¬ ty as, could reasonably have been anticipated, considering the obstacles presented. Notwithstanding the unfavorable weather of last winter, the high water of last spring, and the sickness during the past summer and fall, there has been a large amount of work done, and this ahnount would probably have been increased at least $300,000, but for the sickness. The weather during the summer and fall has been remarkably favorable for canal operations, and particularly for protecting and preparing portions of work upon the summit division for further progress. The part of the line from the south branch of Chicago river to summit or the Point of Oaks, is now placed in such a situation as to insure its safe¬ ty from the high water caused by the overflowing of the Des Plaines river. This has hitherto been the cause of much trouble and delay, and oc¬ casioned, for a considerable length of time, an entire suspension of the work. A small part of the deep-earth cutting in the valley of the Des Plains, between summit and the Saganaskee, has also been protected, so 17 that the work may be successfully prosecuted during the seasons of high water. Upon this part of the canal, the contractors have spent most of the past season in making preparations for a more vigorous prosecution of the excavation, such as building shantees, providing the necessary fixtures, grubbing and clearing, &c.; so that the amount of estimates upon work done is very trifling, compared with that which remains. It should be observed, too, that several of the sections have been relet since the regu¬ lar letting in June last, and the contractors have not yet had time to make full preparations. Tne location of the canal at the Saganaskee swamp and the plan of constructing it have been materially changed since my first estimate was made, and a very decided advantage gained in the expense, in the symme¬ try of the line, and in the increased value of State property. The canal as now located occupies as much of the channel of the river as can be made available upon a straight line. A new channel for the river will be opened upon the west side of a low island or peninsula, which extends the whole length of sections number 42,43, and 44, and will occupy nearly the same place where the main channel of the river appears once to have been. An embankment will be made, connected with the spoil-bank on the west side of the canal at the lower end of section number 41, (which is just above the Sag, and near the present channel of the river,) crossing the river from that point to the island, and running thence across the island to a bayou, which will form a part of the new channel; thence parallel with the canal and about 22 chains from it, upon the west side of said island, to a point near the lower end of it; and thence across to the ca¬ nal upon section number 45, where it will be connected with the protec¬ tion so as to exclude tlip waters of the river. Parallel with and near the embankment upon the west side of the^ island, the artificial channel will be made so as to unite the'bayou above mentioned with'one that extends up from the lower end of the island. This channel will be opened 200 feet wide, and all the earth excavated from it deposited upon the island side. It is believed that a depth of excavation sufficient only to remove the roots will'be all that will be necessary.,; for the whole river being forced into thfe channel by the embankment above described, will cause a current sufficiently strong in time of floods to deepen and enlarge it to the re¬ quisite dimensions. There is a large, deep basin, or expansion of the river below the channel, of sufficient capacity to hold all the deposite that can be washed into it. That part of the canal embraced in sections number 42, 43, and 44, the only sections upon the Summit Division, except two, which are not now under contract, has been very properly withheld from contract since the above described change was made. The only work that can be done upon it to any advantage, previous to the completion of the sections from number 44 to the running out of thé level, consists of earth excavation un- o 1 der water, which it is believed can only be done, with economy, by a dredging-machine. Such h machine your Board has very properly deter¬ mined to build, under the direction of an efficient agent of the State, who should also superintend its operation when completed;1 and it should be in readiness as early next season as practicable. With this machine, all the work upon the three above mentioned sections, except a small amount of rock excavation and walling, can probably be performed by the time B 18 that the sections below will be finished. These once done, the water can be drawn down so that the rock excavation (which occurs only upon sec¬ tion number 44,) and walling, can be performed with little difficulty or delay. When the canal at this point is completed upon the present plan, a quantity of State land, amounting to about 270 acres, will be reclaimed, which is, at present, entirely valueless. The whole of the impassable marsh that now presents so forbidding an appearance will be made dry land. The junction of the canal from Calumet river with the main line, being made at this point upon the reclaimed State land, will make it one of the most valuable town sites upon the line of the canal, or in the State, The importance of the point at this junction will be appreciated when it is understood that the "lateral canal" is the last link in a chain of canals of nearly twelve hundred miles in length which will, by this, be connected with the improvements of our own State. All these canals are believed to be in progress, and some of them are known to be nearly completed, and the whole chain will probably be completed in three or four years, to those who have not watched the progress of improvements in neigh¬ boring States, this statement may appear almost incredible, and the follow¬ ing list is, therefore, given to show that there is no exaggeration.

The canals above ennumerated are intersected at various points by rail¬ roads and other improvements, which will add much to their usefulness, and materially increase the importance of a connection with them. From section number 44 to Lockport, (a sub-division that embraces all the heavy rock excavation,) the line has been permanently protected from the river floods, with the exception of sections 45, 46, 47 and 48, a part of which only requires protection, the rest being above the highest floods. When this work was first placed under contract, it was supposed that all the protection against high water that would be required for the canal after its completion would be made by the contractors for their own se¬ curity during thé construction; or that, if any further defence were re¬ quired, it could be made with greater economy after the canal was finish¬ ed, But the unusual floods of last year rendered it evident that a strong 19 and permanent defence must be made to prevent the influx of the water into the canal : and the serious delay occasioned to the work by the want of such a defence, and the probable recurrence of such delay, satisfacto¬ rily proved the expediency of at once making a protection or defence at the expense of the State, which should be sufficient for all present and future purposes. This protection consists of two parellel stone walls, three feet apart, raised one foot above high water mark, and a wall of well puddled clay between them, extending down to the firm rock be¬ neath, and as high as the top of the parallel walls. The Sag and Big run ditch, extending from section number 45 to Big run, commenced last year, has been completed. The object for which this is designed was explained in my last annual report. The cost of the protection and ditch forms no inconsiderable item of expense, but could not be dispensed with, without causing much delay during the construction, and materially detracting from the value of the canal after its completion. Much labor during the season past has been spent upon the above men¬ tioned work, but as the former is nearly, and the latter entirely comple¬ ted, the whole force that can, in future, be brought -upon the work, may be directed exclusively to the excavation of the canal. The work upon the Summit Division, during the past season, has gen¬ erally been well applied, so that the sections that have been worked upon to any considerable extent are now, with but few exceptions, in a good condition for future operations. Portions of many of the sections upon this divission have been worked to bottom, and several of them will proba¬ bly bè completed in the course of next year. An improvement has been made in the 'plan of constructing sections , number 66, 67 and 68, by building dry walls in front of the embankment, which will somewhat increase the cost, but add greatly to the value of State property and the durability of the canal, and diminish the expense of repairs. In connection with section number 68, which passes through the town of Lockport, and is made 120 feet in width, a hydraulic basin has been estimated, which is to be constructed in such a manner that the mills or manufactories which are to be operated by the water-power created here, will be built upon, and draw their water from, three sides of it—the other side being next the canal and only separated from it by the towing-path, a*street, and a tier of warehouse lots. This basin will be connected with the canal in such a manner that boats or vessels can readily pass into it, and load or unload at the mills and warehouses. # The water will be used here for ihe descent of the first two locks, (which are of ten feet lift each.) though the second lock is located about a mile below the first. A tail race can be made from the mills upon ground of such a level as to require but light rock cutting, except for a * short distance, and the water carried in below the second lock. The value of the water power created here and at other points upon th3 canal, by drawing a supply of water directly from lake Michigan, can be fully appreciated after a season of such severe drought as the past. The Des Plaines river and many other considerable streams of the coun¬ try have been nearly dried up, and probably three-fourths of the water- mills throughout a large portion of the United States have been standing 20 still for the last three months. But had this canal been completed, there would have been, during the season past, an unusual supply of water, as the surface of the lake has been nine fed four inches above canal bottom, or thfee feet four inches higher than was originally calculated upon for the supply. The line from Lockkport to Dresden, a short distance below the Kan¬ kakee bluffs, was prepared for letting last spring, and offered for contract on the 5th of June. All the work offered was let, and at such prices, generally, as were satisfactory, Some of the lowest priced work, howev¬ er, has since been abandoned and relet. In revising the line for letting, the canal was made very nearly straight for the whole distance from Lockport to Juliet. This location varied con¬ siderably from the first survey upon which the estimate was originally made, and the locks are quite differently distributed. The first two locks are, as before mentioned, about a mile apart—the first in the lower part of the town of Lockport, and the second, or lock number 2, just below Fraction run—both upon canal land. Locks number 3 and 4 are located itpon canal land, about 2£ miles below Lockport. The lockage is twenty feet, and the same amount of water-power will be created here as at Lockport. Lock number 4 brings the canal to the level formed by the pool of dam number 1. A short distance below said lock, the line runs into the chan¬ nel of the Des Plaines, which will here be turned to the right, and the whole of the water forced into the channel upon the west side of Nor¬ man's island. The rock excavation in the bed of the river, from the point where the canal enters it to the upper end of said island, averages about two and a half feet in depth; but when the river is turned, the excavation will be attended with no particular difficulty. The excavation continues across the island, running out at the lower end of it, where the towing-path crosses the river, and is thence continued down the right bank to the % guard-lock at dam number 2, where the independent canal again commences. From this point to the termination of the canal, the towipg-path is upon the left or south side. , From Norman's island to dam number 1, which is located upon canal land, just above the town of Juliet, two strong walls, with embankments between them, will be constructed upon the east side, to confine the water in the pool of the dam. It is proposed to raise these walls and embank¬ ments seven feet above the comb of the dam, to be perfectly secure from the highest floods. From dam number 1 to dam number 2, a similar de¬ fence will be required, but of a much less height. c Both dams will be made of good cut-stone masonry laid in hydraulic cement. Dam number I will be connected with lock number 5, which will be upop the west or towing-path side, fclere also a large amount of water-power will be created which, at this point, will be particularly val¬ uable, and confer great additional value upon State property. From Juliet to the Du Page, the revised line varies considerably from the former surveys; This variation was made in order to keep up the level betwçen five and six feet higher than formerly, so as to cross the Du Page by ari acqueduct* This will somewhat increase the cost, but make a piuch better and safer canaL The increased cost will be principally upon 21 the three or four sections immediately below Juliet, and in the aqueduct across the Du Page, which will cost more than the original plan of cross¬ ing this stream in the pool of a dam. The plan was changed after wit- nesssing the floods of the last two years, and being fully convinced that more would be gained by it in safety than would be lost in expense, if, indeed, the increased expense is not more than compensated by the addi¬ tional water-power that will be given upon the State land at the Du Page. This State land will form a town site of no inconsiderable impor¬ tance, being beautifully situated in the heart of a fine country, at a con¬ siderable distance from any town that could possibly rival it. The lock¬ age immediately after crossing the Du Page will be fifteen and a half feet, divided into two locks, number six and seven, and it will be necessary to draw about 4,500 cubic feet of water per minute past these locks, (exclu¬ sive of the lockage water, ) to supply the canal to Marseilles. A feeder will be taken into the canal from the Du Page, about^ three miles above the crossing. The last season has shown this stream to be one of the most permanent in the State, and it can be introduced as a feeder at a very moderate expense. The length of the feeder will be twenty chains, and an embankment is already nearly completed, extending from the head of the feeder up the river twenty-seven chains, and connecting with high ground upon the river bank This embankment, together with that which will necessarily be formed in the construction of the feeder, will exclude the flood waters of the Du Page from a depression through which they formerly flowed into Rock creek. This defence not only secures the safety of the canal, but pre vents' a considerable quantity of excellent land from being over¬ flowed. From the Du Page to Dresden, the line has been but slightly changed since the first survey, but the quantity of slope-wall to protect the canal at the Kankakee bluffs has been considerably increased, to render the ca¬ nal doubly secure at this exposed point. * The cost of the canal around the bluffs, at the present contract prices, will not vary materially, in the aggregate, from the original estimate; and the contractors are men of responsibility and much experience in similar kinds of work, so that its completion at present prices is beyond a doubt. It will, be seen that, in many particulars, the canal from Lockport to Dresden is very much improved from the original design/ In addition to other improvements, betwreen five and six miles of the canal below Lock- port will have walling either upon one or both sides, which will effectually prevent the washing of the banks or any serious danger from breaches. This mode of constructing the canal has been adopted every where that stone of a suitable quality could be convenient^ obtained in the excava¬ tion, and on portions of the distance abovementioned, stone is quarried for the express purpose. These improvements in the mode of construction, and others upon va¬ rious parts of the line which will in some degree increase the cost, have been the more readily introduced in consequence of an important saving in expense upon other parts of the canal, which it was known would reduce the aggregate cost considerably below the original estimate. The line from Dresden to Marseilles has not yet been prepared for 22 jetting, but this should be done as early next spring as practicable, and the whole of it placed under contract. The estimate for this part of the canal will be the same as in my first annual report. From Marseilles to the western termination of the canal, but particu¬ larly below Ottawa, a large proportion of the earth work has been finish¬ ed. Only six sections upon the main line, and one upon the Fox river feeder, have been entirely finished and accepted, but ten or twelve sections mote are nearly done, and might have been completed in October had not sickness caused a serions interruption in canal operations. The work upon the Fox river feeder is so far advanced that it may be completed, withput difficulty, next season. The dam at the head of it is finished, except a small amount of masonry to raise the abutments to the requisite height, and the guard-lock will be done next spring. Several changes in the original plan of constructing portions of the Wester nDivision have been made with a view to greater permanency and utility, or to benefit State property. The change in the canal at Ottawa, for the purpose of benefitting the State property in that place, increased the cost of construction about $12,000, but will enhance the value of the property to a much greater amount. At Pecumsagan creek, a much more expensive and better artificial channel has been formed than was at first deemed necessary. An extra¬ ordinary flood, in Jnne last, destroyed a considerable amount of work already done, and showed the necessity of increasing the expenditure to give additional security to the aqueduct to be built across said chan¬ nel. There having been some injury sustained upon the heavy embankments from section number 191 to 195, in consequence of strong winds during a long continuance of high water, it was thought expedient to protect the banks that were most exposed by a slope wall. Accordingly the whole of section number 194, and parts of sections 193 and 195, have been thus protected, and the whole will probably be made secure before tlfo spring floods. The width of the steamboat channel has been increased, for a distance of 600 feet below the basin, to 160 feet on the bottom, or 60 feet more than it was first estimated. A similar enlargement has also been made for a short distance above its entrance into the Illinois river. Wherever an improvement upon the original plan, increasing the cost over the original estimates, has suggested itself during the progress of the work, the facts have been communicated to your Board, and I have had the satisfaction to find that it has been deemed more important to increase the permanency, utility and symmetry of the canal, and the ulti¬ mate value pf State property, than to keep the cost in every instance within the original estimates. It is well known that when those esti¬ mates were made there had not been sufficient time given to mature plans, or determine, in all cases, the nature of the material that would be met with in the execution of the work. It was my intention to make my estimate high enough in the aggregate, but it was not expected that in all its details it would exactly correspond with the actual cost. Such full developments have now been made upon nearly all the work which has been placed under contract, that its character is pretty well ascertained. 23 The contracts made the past year have generally been made with ex¬ perienced contractors, after they had satisfied themselves of the true value of the work by actual observation of similar work then in progress, and had had the benefit of their own or other contractors' experience upon the same canal for the two years previous. These contracts have been made, in most cases, at prices below the original estimates for the same quality of work, and, with very few exceptions, will undoubtedly bê executed at the prices, and afford a fair profit. If relettings become ne¬ cessary, the work generady will be relet without an increase of prices. ' This opinion has been confirmed by observation and the relettings that have already takeh place. The character of the deep-rock cutting, about which such a diversity of opinion prevailed at the commencement, is now as clearly understood as that of the light earth work. All the sections have been commenced, and considerable portions of many of them excavated to bottom, showing every variety of rock that can be supposed to occur in what still remains. These developments have reduced the cost of this portion of the canal to as much certainty as it is possible to arrive at before its com¬ pletion. Heavy contracts have been taken by responsible contractors, for less than the original estimates, upon quarried rock, and those con¬ tracts, (since the first season,) have, in all cases, been for embodied rock, whether stratified or solid. Were the whole of the rock excavation upon the Summit Division to be offered for contract again at this time, it could, unquestionably, be let to contractors of the highest responsibility for considerably less than the amount of the present contracts. The principal structures of masonry upon the canal have nearly all been,placed under contract the past season, and a commencement made by quarrying and cutting stone. Twelve out of the fifteen lift-locks upon the canal have been let; also two stone dams and a guard-lock at Juliet, the masonry in the abutments and piers of the Fox river aque¬ duct, and two culverts—one of sixteen tand the other of eighteen feet chord. The masonry in the Fox river aqueduct was awarded or let in the fall of 1837, but no commencement having been made, it was relet in June last. The locks will cost less and the aqueduct more than the original esti¬ mate. The quality of the work in the Fox river aqueduct has been changed from hammer-dressed to cut-stone, and in the locks it remains , the same as was originally intended. Since the work was let, quarries have been opened along the line and near it, and stone of a very good quality has been obtained. - Water lime is also found in inexhaustible quantities at Lockport, and in several places upon the Westèrn Division of the canal; and as a contract has been made with a gentleman of undoubted responsibility for the manufacture and delivery of the lime at the places where it is to be used, the cost may be calculated with certainty. All the contracts for masonry, except for the Little Vermilion and Peeumsagan aqueducts, and the guard-lock and dam abutments at the head of the Fox river feeder, w;ere made for so much, exclusive of the water lime, which was to be furnished by the State. This was done, first, to secure lime of good quality and procure it in timej and, secondly, because when the contracts were made it was not known where it would be obtained, nor at what cost. 24 The materials that-will be obtained for the masonry throughout the whole extent of the canal can be, had more conveniently, and of much better quality than was anticipated at the commencement; but in con¬ sequence of the delay caused by the sickness of the past season, it will probably require two seasons more to complete all the masonry which is under contract. By placing the remainder of the work of every descrip¬ tion under contract next spring, or early next summer, the canal may be completed, in three years, from the deep-cut to the western termina¬ tion, unless the seasons should prove more than usually unfavorable. To accomplish this, and proceed at the same time with a force upon the Sum¬ mit Division sufficient to complete it one year later, will require a great additional number of laborers. These might easily have been obtained, had the country through which the line of canal passes proved as healthy the past as the two preceding years. But unfortunately for the credit of the canal, it has been otherwise. There has been much sickness upon this canal, as well as almost every other public work in the west. This may probably be attributed to the long continued and intense heat of the sum¬ mer, and the severity of the drought. But from whatever cause it may have proceeded, it was unusual, and will not be likely soon to occur again. The two preceding years, since the commencement 01" the canal, had been remarkably healthy, and there is no reason to doubt that succeeding seasons may prove equally favorable. When the sickly season commenced in July last, the force upon the canal was rapidly accumulating, but the sickness in August and Septem¬ ber not only discouraged the laborers abroad from coming here, (for exaggerated reports of the unhealthfness of the country were every where circulated,) but caused many that were here to leave the country altogether, or to engage upon other public "works of the State. Since these discouraging circumstances occurred, several of the contractors have exerted themselves to introduce men upon their work .at their own expense, and have expended considerable sums of money to effect this object. Their exertions have been attended with some-success, but it is feared that they will not derive that advantage from the introduction of laborers that their praise-worthy zeal deserves, in consequence of the difficulty of keeping these laborers upon their work after they have been once obtained. It is respectfully suggested whether the State's interests would not be materially benefitted by making a liberal expenditure of money in obtaining laborers from a distance for the canal, either directly through an agent of your Board, or by co-operating with contractors. Much effort will, at all events, be necessary on the part of contractors, and the friends of the canal generally, to correct the misrepresentations that have been made in relation to the sickness, to show the liberal wages uniformly paid upon dhis canal, and the advantages that this country presents over almost every other for the investment of their earnings. The number of laborers upon the canal and connected immediately with canal operations during the past year, as nearly as can be ascertain¬ ed from the returns made upon each sub-division at the close of * 7 • i • The amount of work done upon the canal during the past year is as follows, viz : 1st quarter ending February 2Sth i- $109,417 62 2d quarter ending May 31st - - - - 167,128 67 3d quarter ending August 31st - 409,374 33 • 4th quarter ending November 30th - - - 227,741 93 Total in 1838 - - - - - $913,662 55 Total in 1837 - - - - - 346,899 43 Total in 1838J - - - - - $35,744 83 Total àmount of work'done - $1,296,306 81 This statement will show the progressive increase of labor from the commencement up to this time. It will be seen that but a small amount of labor was performed last winter and spring, in consequence of the unprotected state of the work; and that the amount during the last quarter, instead of being a great,increase upon the summer quarter, as in 1837, shows a vast decrease, in consequence of the cause already ex¬ plained. The amount of wrork let upon the can&l at the public letting in June last, was as follows, viz : Aggregate length of line let upon the Summit Division, exclusive of re¬ lettings,, three miles and 28 chains.

It has been stated, even during the past summer, in some of the newspapers of this State, (and consequently con¬ sidered as an established fact abroad,) that the friends of the canal now generally admit that the canal will cost much more than this estimate. But ,this is far'from being the fact, None of the friends of the canal, who can have any just pretensions to a knowledge of the value or cost of the. work, ever made such an admission. On the contrary, when it was discovered that a much greater quantity of rock excavation had been estimated upon the Summit Division than would be found, the canal was known to have been over-estimated, notwithstanding considerable addi¬ tional improvements were made upon other parts of the line in conse¬ quence of this saving. * The cost of the Ottawa side-cut which was not Included in the original estimate, is embraced in this. 27 In submitting an estimate of the cost of the canal as it now is, I am not governed by my own judgment alone, or that of other engineers. A very large proportion of ÙJ whole work, and all that was ever supposed to be of a doubtful character, is under contract, and much of it in the hands of men of great experience, sound judgment, and undoubt¬ ed responsibility. They have generally taken the work at prices a shade below the estimates. All the work which is not under contract is esti¬ mated at prices at least as high as existing contracts, and no doutt is entertained that the work can be done as low as the estimates. E/ery item of work has been embraced which it is now supposed can possibly be necessary, in order, as nearly as practicable, to show the entire cost of the canal; but it is not pretended that any thing more than the 'probable cost can be shown until the whole work is fully completed. A vari¬ ety of circumstances may occur during the progress of a work of this mag¬ nitude, which cannot now be anticipated, that may, in some degree, either increase or diminish the cost, but cannot cause a material variation from the present estimate. The accompanying reports of Messrs. Talcott, Jerome, and Burnett, resident engineers, will give a satisfactory account of the progress and situation of the work upon their respective divisions. The tabular state¬ ments annexed to eadh will show the names of the contractors, the quan¬ tities and amounts of the various items of work performed at the prices allowed, the sections which are and those which are not under contract, and the aggregate cost of each section, embracing all the items whether at contract or estimated prices. All which is respectfully submitted. WM. GOODING, Chief Engineer Illinois and Michigan Canal. Canal Office, Lock port, December, 1837. To the Board of Commissioners of the Illinois and Michigan Canal. Gentlemen: Agreeably to your request, I have collected such facts in relation to the canal as my duty has led me particularly to observe; which I have the honor to submit in the following report. Although the amount of work done upon the canal, during the year past, has not equalled the expectations of many of its friends, yet a great number of sections, embracing a vast amount of work, have been suc¬ cessfully commenced, and several of them on the Western Division nearly completed. The number of laborers has continued gradually to increase, and there are now as many upon the line as the contractors are at present prepared to receive. The want of labor that was so much felt last year and the beginning of the year 1837, and which for a time so much retard¬ ed the progress of the work, it is presumed, will not again exist. It is now generally known abroad that the country through which the line of canal passes is very healthy; that several thousand laborers may here find con- 28 stant employment for a number of years; «and that no country in the world affords such advantages for the investment of the earnings of this class of men. The number of laborers engaged upon the canal, on the first of Decem¬ ber last, was not far from 350, and the force was not much augmented till the opening of spring navigation. There are now actually employed upon the canal, and in the various operations immediately connected with caml construction, about 1,700 men. This number might have been greitly exceeded, had not many of the contractors been negligent in pro¬ viding tools and accommodations for the number of men requisite to pro¬ gress with their work as rapidly as their contracts required. This delay was, for a short time, in some degree excusable, in consequence of the hard times and scarcity of labor; but where sections have been suffered to remain a whole season without being commenced, or where a com¬ mencement seems to have been made barely for show, and no reasonable assurance has been given of the ultimate prosecution of the work, from the progress already made, or from visible preparations commensurate with the magnitude of the job—there can be no doubt that the interests of ' the State will require a reletting as soon as efficient contractors, with the necessary means, can be lbund, who will take the work at fair prices. On this as on other canals, many contractors have sought for and ob¬ tained more work than they can accomplish—some by overrating their means or ability, arid some with the intention of selling out—they re¬ ceiving the profits, and others performing the operations. Where such has been the case, and the contracts have been clearly forfeited, your Board may very properly effect a division of the work by reletting such sections as the original contractor gannot or will not prosecute, and allow¬ ing him to retain such an amount of work only^ps he can conveniently manage. The amount of work performed during the year has been considerably less than it would have been but for the unfavorable weather that has so much of the time prevailed'. The last winter was one of unusual rigor, and the wet weather .during the spring, summer, and fall, without a pre¬ cedent since the first settlement of the country. The streams for a great part of the year have been very high, particularly the Des Plaines river; but less interruption to the execution of the work Las resulted from this cause than might have been anticipated from the unprotected state of most of the sections; and it has been clearly shown that a defence can be made, at a moderate expense, that will render the whole work perfect¬ ly secure during the highest floods. The high water in the Illinois river has been the cause of serious delay in the excavation of the steamboat basin and channel at the termination, and a large force will be requisite upon that work as soon as a favorable season for operations shall be pre¬ sented. The amount of work done on the canal, from December 1, 1836, to December 1, 1837, according to the monthly estimates, is as folliows, viz: 29 Upon the summit division - $180,536 97 Upon the western division - 166,362 46 Total - - - - - $346,899 43 Far the most important item of work embraced in the above amount, is the rock excavation on the Summit Division. Considerable progress has also been made in the deep earth excavation between Chicago riv¬ er and the Point of Oaks, but there has been so much water upon the surface since the work was let, that the side ditch, which is to be formed on the south side of the canal without the spoil-bank, has not yet been finished ; nor but a. small part of the bank on the north side, which is to guard against the water that flows from the Des Plaines river in time of floods, and which is to be formed of the earth excavated from a ditch within the prism of canal. On section number 1, several chains in length have been finished, and on other sections of this part of the line, portions have been sunk to bottom. On most of the sections of deep rock cutting which have been in progress during the year, small portions are now at bottom, so that the quality of both the rock and earth excavation th-ough the deep cut is now well undersood. Enough has been done to fully "demonstrate the charac¬ ter of the work, and show the ease with which it may be executed. Contractors, therefore, who have recently taken work, have done so with a better knowledge of the subject than could previously be obtained. The estimate of a part of the Summit Division, contained in my re¬ port of last year, has fortunately proved much too high. A large portion of the excavation between the Point of Oaks and the mouth of ;thé Sa- ganaskee swamp was supposed, from the examinations made, to be rock, and estimated as such; but test-pits or shafts have this year been sunk, which show that the excavation will consist principally of clay and gravel, with a small portion of detached rock. Since this erflor in relation to the quality of the excavation was discovered, the work has been re-estimated, and much of it let at prices below the estimates. This error in my last year's estimate, which originated in consequence of a want of time to make the proper examinations, will considerably diminish the cost of the Summit Division. During the past year, the greater part of the Middle Division has been carefully revised from Lockport to Juliet (and a survey made of the routes through Juliet) under the direction of Mr. Talcott, and the remainder un¬ der the direction of Lieut. Burnett, resident engineer, assisted by Messrs. Preston and Ryan. Some slight changes in the route of this portion of the canal have been made, though it remains essentially the same. The principal alterations are between Lockport and Juliet and the Aux Sable and Settle creek. This division can now be feadily prepared for letting, as very few other changes will be necessary. A change was made in the line of canal opposite to, and for a short distance below Ottawa, on the Western Division, agreeably to instructions received from your Board, in order to enhance the value of State proper¬ ty at that place. The change was one unquestionably benefitting the State interests, but considerably increasing the cost of the canal. Work, 30 to the amount of $1,449 63, had been done on sections 168 and 169 upon the old line. These sections are now nearly completed. From section 188 to 195, inclusive, a large quantity of heavy embank¬ ment has been made, and it is believed that the most of these sections (except the structures and the steamboat basin which is on section 195) may be finished next year. The cost of some sections on this division, and probably on each of the others, will be greater than was anticipated before the quality of the work had been minutely examined. Rock, or a different kind of excavation from that which was estimated when the location was first made, some¬ times occurs, and will, of course, increase the expense ; but, on the other hand, many sections will cost much less than the first estimate. It was supposed, when my report was made to your Board last year, that several causes might operate to reduce the cost below the estimates then made. One cause suggested was a more general attendance of effi¬ cient contractors, and consequently more competition ; another, a reduc¬ tion in the price of labor. Both of these causes have this season fortun¬ ately operated in favor of the canal. The two public lettings (on the 20th of May and 13th of November) were well attended by contractors of known skill and experience, and the work has been generally let below the estimates—partly, no doubt, because the character of the work was better understood, but partly because the price of labor has been so much reduced. The wages generally, for the year past, have been twenty dol¬ lars per month—six dollars per month less than the year preceeding. The work that has been placed under contract the past year is as fol¬ lows, viz: Aggregate length of lettings on the Summit Division, exclusive of relet¬ tings, eighteen miles and twenty-five chains. v The amount at estimates - - - $2,011,332 03 The amount at contract prices ... 1,925,364 33 Less than estimates - $85,967 70 \ ■ .

The amount of all the work let at contract prices $3,244,234 97 All the Summit Division, except twelve sections, and nearly all of the Western Division below Marseilles, are under contract. Several sections have already been relet, but generally as low as the original contract prices ; yet it would obviously be an error to calculate on the completion of the whole work without a liberal allowance for relettings. Even were the prices in all cases high enough to complete the work with judicious management, still the work will not all be judiciously managed ; and though it may frequently be relet at fair prices, the State will sometimes have, at last, to pay more than its actual value, in order to have it execu¬ ted in proper time. During the past year, ditches have been laid out, placed under contract, and partly executed from the Point of Oaks to Chichgo river, and from the mouth of the Saganaskee swamp to Big run ; the object of which is to receive and carry oft' the water which must otherwise drain into the canal, or accumulate behind the spoil-banks. By the aid of thèse ditches, the water (except what falls within the spoil-banks) may be effectually pre¬ vented from conveying deposite into the canal, and also from interrupt¬ ing the progress of the work during the construction. At the mouth of the Saganaskee swamp, the canal has been so loca* ted as to reclaim a portion of a canal section (section number fifteen,) which will be made very valuable, if the junction of the "lateral canal" with the main line be made at this point. The cost of the canal will not be materially changed by the slight change which has here been made in the location, though the character of the work will be different. The quantity of rock excavation will be much diminished, but a large amount of embankment required. Two parallel embankments,'one upon each side of the canal, must be made the whole length of sections number 42, 43, 44, and part of 45, or more than a mile and a half, and the excavation of the canal made be-, tween them. The water between the banks must necessarily be thrown out by machinery, which will bave to be kept constantly in operation during the construction. It is important that the contractors should use their exértions to introduce the most economical method of pumping the water from their work, as this at present forms no inconsiderable item of expense. This expense will be comparatively trifling when the proper defences are made, and more perfect machinery used. Messrs. Greenwood and Bishop (contractors for sections 13, 14, and 32 15,) have erected a steam-engine for pumping, which is more than ade¬ quate to discharge the water from their work under the most unfavora¬ ble circumstances; and it is believed that this power will be far the most economical where the quantity of water to be raised is great. No mechanical work upon the canal has yet been let, except the masonry in the abutments and piers of the Fox river, Pecumsagan, and Vermilion aqueducts, and the dam and guard-lock at the head of the Fox river feeder. It will probably be expedient to let all the structures between Marseilles and the termination early next spring, so that this part of the line which is to be supplied with water from the Fox river feeder may be ready for navigation in the autumn of 1839. This may easily be accomplished if the contractors will use proper exertions; and, if they do not, it may be proper either to relet the work, or finish it by State agents. The completion of this part of the canal will be important not only with regard to navigation, but also on account of the extensive hydraulic power that may be immediately brought into use, and which will add vastly to the value of the State property at Ottawa and La Salle. • A portion of the Middle Division should probably also be let in the spring. The line from Lockport to the, foot of the Kankakee bluffs, which Will include a great number of structures, and the most of the heavy work that now remains to be let, should be first placed under contract. This part of the line is through a beautiful section of country, which would furnish a large quantity qf supplies; and the work is of a kind io invite the attention of the most skilful contractors, and insure its com¬ pletion at fair prices. There is now but little doubt that laborers enough can be procured for all the work that is let, and that which it is proposed to place under con¬ tract next year. The force upon the canal during the past year, and par¬ ticularly during the summer and autumn, has been rapidly accumulating; and laborers are still coming in considerable numbers, notwithstanding the lake navigation is closed. The gradual accumulation of the force upon the canal will be shown by the estimates for each quarter of the past year, which are as follows, viz : 1st quarter ending 28th February - - - $7,902.01 2d quarter ending 31st May - - - - 55,647 62 3d quarter ending 31st August - - 112,044 02 4th quarter ending 30th November - - 171,305 78 / Total - - - - - - $346,899 43 I ' '■ r : " The entire cost of the Illinois and Michigan canal will probably la]l con¬ siderably s hdid of my estimate of last year; yet experience has shown that the actual cost of any great public work cannot be determined with certainty until its completion. The fluctuation in the price of labor and supplies, and a variety of other causes, render it impossible to estimate the exact cost of doing work at any future period; but when many experienced contractors readily contract for work at prices as low or lower than the es¬ timates, it may reasonably be inferred that the estimates are generally high enough, and that no attempt has been made to underrate the cost of the canal. 33 Early in the year, and previous to the revision of the Middle Division, the locating party under the direction of Lieut. Burnett proceeded to make a survey of the lateral canal (agreeably to the law authorizing the same) connecting the Illinois and Michigan canal with the Calumet river, and througn this river, with the Michigan and Erie canal of Indiana. His very satisfactory report, which I take great pleasure in communi¬ cating to your Board, will show with what care and ability he has execu¬ ted this duty, and the praisë that he and the young gentlemen who have assisted him so justly deserve. This canal must be regarded as a valuable auxiliary to the Illinois and Michigan canal, and an important link in the chain of internal navigation in the Western States. By this a direct communication with the head of lake Erie will be obtained by a canal, not exceeding 300 miles in length, (composed of the lateral or "Illinois and Indiana canal," the "Michigan and Erie," and a part of the u Wabash and Erie canals,") which will be particularly useful at such seasons of the year as the lake naviga¬ tion is uncertain or hazardous. It will connect with a chain of ca¬ nals in the States of Indiana and Ohio which passes through the valleys of the Wabash, the White river, the Maumee, and the Miami, and con¬ nects with the Ohio river at Evansville and Cincinnati. Although this vast chain of canals is not in the general direction of the commerce of this State, yet it is believed that this communication will ultimately give a great accession of business to the Illinois and Michigan canal, by the cheap and safe intercourse established with the various parts of the country thus connected. The cost of this lateral canal will be trifling, compared with the im¬ portance of the object to be obtained by its construction. The accompanying report, maps, arid profiles, of Lieut. Burnett, will convey all the information that your Board may require in, relation to the. route, cost, and plan, of said canal. The engineers employed by your Board have generally displayed a laudable zeal in the fulfilment of their duties. Mr. Talcott, the resident engineer on the Summit Division, as¬ sisted by Messrs. Hanchett and Gooding, and Mr. Jerome, the resident engineer on the Western Division, assisted by Messrs Robinson, O. S. Je¬ rome, and Killaly, have performed their duties in the most prompt and satisfactory manner. The recent visit of Judge Wright, an engineer whose high reputation for judgment, skill, and experience, has been well earned by a long course of useful service in his profession, has given great satisfaction to the friends of the Illinois and Michigan canal ; and it is believed that his ap¬ probation of the present plan and location will do much to reconcile con¬ flicting opinions concerning it. During his visit he made an examination of the whole line of canal, and his attention was called to every portion of it where the least difference of opinion could prevail in relation to the lo¬ cation and plan of construction, He took much pains to make himself thoroughly acquainted with every fact necessary to lead to a just conclu¬ sion, and though his visit Was but short, his opinions were not formed without due deliberation, and may therefore be relied upon with great confidence. All of which is respectfully submitted. WM. GOODING, Chief Engineer Êlinoisand Michigan Canal. C 34 B. Lockport, December 10, I83SL To William Gooding, Esq, Chief Engineer. Sir: In compliance with your request, I herewith present the following report upon the Summit Division of the Illinois and Michigan canal. For the purpose of rendering the following remarks more perspicuous,, I have considered the line in three sub-divisions, agreeable to the general topography of the country and the progress of the work : the first divis¬ ion extending from the south branch of Chicago river to the "Point of Oaks," or Des Plaines river ; the second from the "Point of Oaks" to, and including the Saganaskee valley; and the third from said valley to Lockport. Upon resuming charge of the line in March, 1837, I found nearly every section that had been commenced overflowed by the Des Plaines .river, and the work nearly suspended. It was, however, generally resumed in May following. x The first sub-division, extending from section one to fifteen, inclusive, was the second time offered for contract in May, 1837. The unfavorable appearance of the work (nearly one-half of which was overflowed by the river) prevented much competition, and the proposals received were considered much above the real value of the work. Sections one, two, and three, only, were awarded. The commissioners then determined to defend the work by a continuous embankment on the north side, formed by excavation from the prism of the canal, and on the south by a .ditch without the spoil-bank, to receive the drainage of the country which is discharged into the southernmost branch of Chicago river. A contract was accordingly made for this purpose ; soon after which contracts were made for the construction of the main work, at the engineer's estimate, subject to the contract for the defence. Owing to inefficiency in the con¬ tractor, the work of defence was abandoned at an early stage, and subse¬ quently awarded to the contractors for the main work, according to their respective sections. The season was far advanced before much progress had been made, and the imperfect protection proved no defence against the unusual high water in December, 1837. Nearly every section that had been commenced was overflowed, and the work generally suspended during the winter. It was resumed early in the spring, and throughout the past season has been prosecuted with considerable energy. The plan of defence is now com¬ pleted, and what has hitherto been considered one of the greatest obsta¬ cles to the construction of this part of the line effectually overcome. From the general character of the excavation, (which consists principally of a very compact blue clay, occasionally intermixed withjfine gravel,) no great difficulty can be experienced in.keeping the work clear of water. It is now in a favorable condition for the coming winter; during which it can be advantageously prosecuted. At the time of making your first annual report, the work on that part of the line included in the second sub-division (embracing sections 16 to 44, inclusive,) was supposed to consist principally of rock excavation. The circumstances which induced that opinion were the regular rock for¬ mation which appears on the west side of the Des Plaines river, opposite the -'Point of Oaks," and forms its bed for some distance above and belowr 35 this point. It was, therefore, natural to suppose the same geological con¬ struction would be found on the east side of the river, and, time not per¬ mitting the usual examinations by sinking shafts, it was considered in the estimate as stratified lime-rock. Examinations were made during the summer and autumn of 1837, which show that no regular rock formation exists on this part of the line, until we reach the south side of the Saga¬ naskee valley. The excavation will consist chiefly of clay and gravel, a small portion of detached rock, with an occasional vein of sand—-the strata varying frequently in compactness and relative position. That part of the line opposite to the Saganaskee valley was examined with reference to adopting the present channel, and changing the river to what appears to have been its former channel on the west side of a penin¬ sular island. These examinations were made at a high stage of water, which rendered it difficult to make them with the desirable precision. The data presented, however, were considered sufficient to determine the loca¬ tion by avoiding the river, yet approaching it somewhat nearer than the original line, and improving its general direction. Upon this location and some slight changes in the line above, this division, together with all the sections upon the Summit Division not then under contract, was offered for letting in November, 1837. The principal part of the sections were awarded ; but, in consequence of their not being commenced within the prescribed time, several were declared abandoned, and some of them sub¬ sequently relet at the engineer's estimate. The winter of 1837-8 afforded a favorable opportunity for making a more critical estimate of the river opposite to the Saganaskee valley. Its bed in many places was found to be from six to eighteen inches below the bottom of the canal and of the necessary width; but its meanders pre¬ cluded the possibilityy>f obtaining a symmetrical line which would embrace the full benefit of the channel for any considerable distance. The margin of the channel was particularly examined, and found to consist entirely of a vegetable deposite from twelve to sixteen feet deep, and approaching so near a fluid state that two men could with ease force a sounding roa through it to that depth. - For the purpose of making a just comparison, that part of the line, lo¬ cated in November, which passes across the bayou or expansion >pf the river and along its margin, was also examined with much care. Upon these examinations the following comparative estimates were prepared: Line located in Nov., length 127.08 chains, esti¬ mate ^ - - - - - $452,815 00 Line through river, length 126 chains, estimate - 324,204 00 V ' ' Showing a difference in favor of the river line, of - $128,611 00 Upon these estimates and an examination of the ground, the commis¬ sioners adopted a line passing through the river varying slightly from that upon which the examinations were made. 1 This plan involved a change in the line above this point, much improving its general direction—the line being now direct from the centre of section 36 to the centre of section 45, or 3 miles 54.18 chains, between the points of deflection. The change will somewhat increase the quantity of grubbing and excavation on sec- 36 tions 38 and 39, and slightly diminish the excavation on sections 40 and 41; but the difference is trifling, compared with the general result. It may here be proper to remark that the item for lorming a new chan¬ nel for the river, and an embankment to confine and direct its waters, was based upon somewhat hypothetical data. The whole surface being then covered with a heavy mass of ice rendered it impracticable to make a critical estimate. 1 have recently examined the ground minutely, and prepared an estimate upon the plan of making a channel 200 feet wide, and an embankment raised three feet above the highest water, at the prices for which the work is contracted to be performed. The length of the line between the extremes of sections 41 and 45 being less than that embraced in the comparative estimates above mention¬ ed,! have revised the estimate accordingly, which will be found in the gen¬ eral tabular statement of the cost of the several sections. In woik of this character, it is difficult to anticipate all the contingencies that may occur in the course of construction, and the most careiul estimate may be exceeded in the aggregate cost. The quantity of earth apd rock exca¬ vation, as well as the prices at which they are estimated, is considered liberal; it is, therefore, confidently believed that this part of the line can be constructed at a cost not varying materially from the estimate. Between the Point of Oaks and the Saganaskee valley, there will be required four receiving reservoirs for the drainage of the country. These will consist of a pit formed in the rear of the spoil-bank, about thirty feet square, excavated to two feet below top-w ater line of canal, with the sides and bottom paved, and communicating with the canal by a narrow pas¬ sage. It is believed that these will receive the deposite usually carried into a canal by the drainage-water—forming bars expensive to remove, and frequently proving a serious embarrassment in the navigation. The cost of these, together with the grading of the towing-path, paved water-ways to receive the falling water into the canal without injury to the banks, and all work not under contract, is included in the aggregate cost of the sections. The sections not previously under contract throughout the Summit Di¬ vision were let in June last. Many of them have been commenced, and generally they are believed to be in the hands of efficient men. The third sub-division,embracing sections 45 to * 8,inclusive, comprises the deep rock excavation. Each of these sections have been commenced, and several of them excavated to bottom, from twelve to thirtv-five rods in length. During the season of 1837, this part of the work progressed with an increasing vigor until the unusual rise of the river in December, which overflowed several of the jobs and suspended further operations until the ensuing spring. Under these circumstances, it became apparent that it would be imprudent to rely upon the protection which the contrac¬ tors might think proper to make, though bound, in self-defence, to make it efficient. It was therefore deemed advisable byuhe commissioners to construct a permanent and continuous defence against the waters of the river and the drainage of the country, at the expense of the State. This may now be considered as complete from section 49 to 60, inclusive—the work belôw 60 not being subject to overflow from the river. The pro¬ tection on sections 47 and 48 is not far advanced ; but, from their relative position, no danger can accrue to the work below There can no longer 37 be any apprehension of delay or interruption to the uniform progress of the work from this cause. The falling water, and what filters through the fissures of the rock, is readily discharged by the ordinary pump worked by horse-power. As the work progresses, however, and a larger surface is to be drained, a resort to steam power will probably be found the best economy, though not indispensably necessary. Several contrac¬ tors are making arrangements to procure steam-engines during the winter. The sickness of the past season has materially checked the progress of the work ; and though the general health of the country is restored, the work has not yet assumed its former vigor. About 150 men have recently been brought from Canada, and two of the Contractors are now absent for the purpose of procuring others. Agents are employed for this object; and from the efforts now making, a considerable reinforcement may be expected in the course of the win¬ ter. An accession of at least 3,000 men should be made to this division early next spring. The following amount of the estimates for each quarter of the years 1837-8, will show the comparative progress of the work. 1837.

Wherever the work has not been laid out, the estimate of quantities has been made liberal, being desirous rather to exceed than underrate the cost. From section 16 to 44, inclusive, from one to two thousand cubic yards of detached rock per section has been estimated. The variation of this item will slightly vary the cost of the section. Observation and developments of the general character of the work during its progress, thus far, confirm the opinion that the contract prices are adequate to the construction of the work. On the rock cutting, it will be observed that in some cases considerable discrepancy exists between the present and the original estimates. This arises in some cases from a misconception of the relative quantity of earth and rock at the time of making the first estimate. This cannot be cor¬ rectly ascertained until the superincumbent earth is removed and the sur¬ face of the rock fairly exposed. On many of the sections this has been done, and the quantities carefully estimated; on others, such data has been obtained, by a partial removal of the earth, as to render the present estimates a very close approximation to the true amount. Some of the sections have been let at prices higher than the first estimate, and some relinquished and subsequently let above the first prices. The most strik¬ ing difference exists in sections 66, 67 and 68. This is in consequence of a change from the original plan of construction. It was at first designed to form only a single bank for the towing-path, and suffer the water to expand over the low ground on the opposite side, which at present is ren¬ dered a marsh by the overflow of Big run. By the present plan, the ca¬ nal is to be confined within regular banks faced with rock taken from the excavation ; and the waters of Big run confined by a guard-bank extend¬ ing from the bluffs to the head of section 66, where, in connection with the surplus water of the canal, and the accumulated drainage of the country from section 46 to this point, it is received into the canal and discharged directly opposite by a sluice or water-way 500 feet in length. ' This arrangement adds much to the permanence and symmetry of the canal, and reclaims about 300 acres of valuable land, 200 of which belong to the State. The structures embraced in the estimate consist of a towing-path bridge over the south branch of the Chicago river—three road bridges over the canal—a bridge over the Des Plaines river at the Sag^—a stop gate on section 74—a water-way and tow-path bridge on section 66—a wooden culvert on section 67, and the hydraulic basin on section 68. Believing that it will frequently be found advantageous to the commerce of the country, for the lake vessels to navigate the canal as far as Lock- port, turning or pivot bridges have been estimated. The formation of a basin at the forks of the Chicago river being consid¬ ered as part of the general plan of the canal, is also embraced in the pres¬ ent estimate. Respectfully submitted by Your obedient servant, EDWARD B. TALCOTT, Resident Engineer. 43 C. To William Gooding, Esq., Engineer in Chief on the Illinois and Michigan canal. Sir: In pursuance of your directions, I proceeded with my party, ear¬ ly *last spring, to revise, locate, and prepare for letting, that portion of the Middle Division of the Illinois and Michigan canal embraced between Lockport and Dresden, a distance of twentv-one miles—sub-divided into forty sections, of forty-two chains each. From Lockport to Juliet, a dis¬ tance of three miles and sixty-six chains, the line is entirely changed from the original survey. At the beginning of this division, is located lock num¬ ber 1, often feet lift, with a guard of two and a half feet, to meet the con¬ tingency arising from the fluctuation of lake Michigan. One mile below, is located lock number 2, of ten feet lift ; and about one mile and a half above Juliet, locks number 3 and 4, often feet lift each. For three-fourths of a mile above, and nearly through Juliet, the canal occupies the bed of the Des Plaines river, and is of increased width. The banks for this dis¬ tance are to be raised some feet above the ordinary height, and to be pro¬ tected from the wash of the floods by substantial walls on the inner sides. The river is to be raised to the requisite height by two stone dams at Juliet. With the upper dam is connected lock number 5, of ten feet lift, with a guard of four feet, making a valuable water-power on canal land. With the lower dam is connected a guard-lock; at which point the canal leaves the river. * Owing to the great height of the spring floods, it became apparent that the line from Juliet to and over the Du Page river wrould be benefitted by being located on a higher level than the former, of some five or six feet. This location varies the line some considerably from the original, although, taking the whole distance, the cost of construction is not materially chang¬ ed; and it is believed that a better location has been obtained. By this means the Du Page river is passed by an aqueduct sufficiently elevated above the highest floods to secure its permanency. About three miles above the aqueduct, the Du Page is to be received into Jthe canal by a side cut of twenty chains in length, connected with a dam across said river. There is to be a guard-bank extending from the dam up the east side of the river twenty-six chains. This bank is deem¬ ed necessary to prevent serious injury, which would otherwise accrue to the canal at this point, from the high floods. Immediately below the aque¬ duct, are lncated locks number 6 and 7, with an aggregate lift of fifteen and a half feet. From thence to Dresden, a distance of five miles, the line occupies nearly the ground of the original location. The greater portion of this distance, the canal passes at the foot of the Kankakee bluffs; some part of the way in the edge of the Des Plaines and Illinois rivers—the towing path bafik to be protected from the great floods and extensive ice jams formed by the uniting of the waters of the Des Plaines and Kankakee rivers, by a strong wall on the river side. Especial reference was had, in locating the above twenty-one miles of canal, in such manner as would best afford those wishing to make an ex¬ amination of the work, every facility to do so with accuracy; the nature of the excavation being expressed by shafts sunk at suitable distances—a large stake properly registered planted at the beginning of each section, 44 with intermediate stakes once in sixty-six feet, with the coresponding levels recorded on the same. The plans, maps, and profiles, together with an estimate of the cost of the above work, were prepared and submitted prior to the letting on the fifth of June last; at which time this portion of the canal was put under contract. The work generally was commenced as per requirement, and prosecuted the brief time intervening between that period and the be¬ ginning of the excessive sickness which prevailed through this section of the country, during several months of the past season—with very consid¬ erable vigor, giving flattering hopes that this portion of the work would be completed in the time specified. From the first of August to about the first of November, the severity of tne sickness caused an almost entire cessation of the progress of the work, notwithstanding most of the contractors were endeavoring to ad¬ vance it as fast as circumstances would admit. In a few^ instances con¬ tracts have been abandoned and relet; but at present there seems to be generally, among the contractors, a disposition manifested to make all suitable progress with the work. Some sections are already nearly com¬ pleted, as a reference to the tabular statement will show. The number of men employed upon this division of the canal, on the first of September last, was 145, and the work done was $48,468 42. The number of men employed on the 30th November, is 607, and the amount of work done, is $37,857 25; making the total amount of work now done on this divis¬ ion, to be $S6,325 67. The remainder of this Division, a distance of about seventeen miles, has not been resurveyed ; but a tabular statement of your former report, showing the cost of construction of that portion of the canal, is annexed. The annexed tabular statement is designed more fully to show the amount of the different denominations of w ork done, the amount of work to be done, and the total amount when done. 40 Tabular Statement showing the work done, and iheprices allowed for the gan Canal, from section number 69 to section 108, inclusive, to the work not wader contract on each section; and ihet total amount when Names of Contractors.

To the Honorable the Board of Commissioners of the Illinois and Michigan Canal. Gentlemen: I have so extended the limits of this my annual report as to enable me to furnish you with a statement of the entire transac¬ tions of this office for the two years last past. This presentment of my accounts, although not required by law, will, I flatter myself, prove more satisfactory to you and to all concerned, as it will exhibit the nature and extent of the operations of this office, since the date of the last report of my predecessor. In connection herewith, see accompanying paper, marked A. The disbursements of this office for the year ending on the 4th of De¬ cember, 1837, amount to - - - - $346,178 95 Those of the year ending on this inst., amount to - « 986,355 85 ■*& « Aggregate disbursements since the last biennial report . $1,332,534 80 Of this sum there was paid out for the use of the con¬ tingent fund for the year ending on the 4th De¬ cember, 1837 - - - r - $49,000 00 Ditto for the year ending this inst. - 105,956 37 Entire payments to this fund, for 1837-8 - - [$154,956 37 The loans authorized, by the acts of the 9th January, 1836, and the 2d of March, 1837, have been obtained. Of that authorized by the first named act, $100,000 in 1836, and $400,000, the residue, in 1837. The first item, with the amount of the premium thereon, at five per cent, was deposited to the credit of the "canal fund," in the bank of the State of Illinois, on the first of July, 1837, at an interest of four per cent, until it should be, by order of the Treasurer, transferred to the Chicago Branch Bank. The remainder, stated at $400,000 with $20,000, the amount of the premium thereon, was deposited in the same institution, to the credit of the State ot Illinois, on the first of January 1838, at an interest of six per cent, so long as it should stand to this credit—and when transferred to the credit of the "canal fund," by the requisitions of the Treasurer for sums none less than $105,000, to bear an interest of four per cent, until such sums should be again transferred, in sums none less than $20,000, to the credit of the Treasurer, in the Chicago Branch Bank—when all interest in favor of the "fund" was to cease. The second loan was made in 1838, and the proceeds thereof, to the am ount of $500,000 credited to the "canal fund account," on the 20th of November ult., by the "Bank of the State of Illinois." The entire amount of interest realised from the deposites of the pro¬ ceeds of loans, is $11,211 67; which is the exclusive receipt from the de¬ posites of the proceeds of the loans, under the act of the 9th of January, 1836. 54 It will appear then that the entire amount of moneys borrowed up to the present date, is - - - - $1,000,COO 00 That the entire amount of premiums is - 25,000 00 And that the aggregate amount of interest realised on loans and premiums is - - - - 11,211 67 Aggregate proceeds of loans up to this date $1,036,211 67 $348 94 4,025 00 3,150 00 The debit side of the "interest account" stands thus : A mount of interest on an over draught of $80,000 - Amount of interest paid on two advances made by the State Bank, one of $210,000 for September 1st, another of $140,000 for October 1st, both to the 21st of November uit. - f Amount of interest due on $100,000 of canal stock, first of Januarv, 1838 - - % i v 7 # Amount of interest and charges subject to be de¬ manded by the Fund Commisioners for an advance in payment of interest due on $500,000 of canal stocks, 1st of July, 1838 To which may be added $3,333 33, the amount of interest paid in ad¬ vance on the last sale of canal stocks, so as to make them bear interest from the 1st of January next.

To the Board of Commissioners of the Illinois and Michigan Canal. Gentlemen: Having been appointed by your honorable Board, under the 3d section of the law of the State of Illinois, of March 2, 1837, "to survey and examine the route of the canal as now established, with a view of ascertaining whether there is a sufficient quantity of water, with¬ in the legitimate authority of the State of Illinois to use, to supply a ca¬ nal of the same size and dimensions as the one now contemplated to be constructed upon the Summit level of said line of canal;" I have, in pur¬ suance of the duties here pointed out, passed over the whole line of canal from lake Michigan to Peru, examined all the plans and profiles, and re¬ ceived explanations and descriptions of every part of the work as projected and marked out, as well as all those parts now in progress of working under contract; and I think I may say I have now possessed myself of a full knowledge of the details of the work, as designed by your chief engineer, in all its localities and bearings upon the very important question of water, upon which I am required to act. It appears by act of the Legislature above referred to, that "a supply of water from sources within the legitimate authority of the State of Illi¬ nois," was to govern all actions upon this matter, and that your Board had early directed Fox river to be more fully examined than had hereto¬ fore been done. From an examination of the various canal documents of the last ses sion of the Legislature, it seems that the question stands as follows : Shall the feeding water be taken from lake Michigan by a deep cut? or, shall the Summit be raised ten feet above the lake, and fed from streams to be brought into it? It has been supposed, and no doubt correctly, that only three streams of water can be brought on the Summit level—1st. The Des Plaines river; 2d. The Calamic river; 3d. The Fox river. The Des Plaines was not in a proper situation to gauge, as there had been copious rains; I therefore take the former measurements of the United States engineers, as stated in the reports of the canal committee, at 54,800 cubic feet per hour. By calculation it is found that, if twelve boats pass per hour, the lock¬ age water to lock up and down ten feet will be 475,200 feet per hour. If we then add for leakage at the locks (a small item) and for the evapora¬ tion, we ought not to say less than 500,000 cubic feet of water per hour will be required, when boats are passing as fast as they can be let through (or twelve per hour.) It is true that, if boats passing each way were to meet so as to pass a boat up with the same water which passed one down, then only half the above amount of lockage water should be estimated for the twelve boats per hour, although, I believe twelve boats per hour may be passed each way, if the locks are well attended, and are in perfect or¬ der for filling and discharging the water rapidly. These premises being admitted y we have to look for 445,200 cubic feet of water per hour more than the Des Plaines gives us at low water. The Calamic takes it sourcè in the State of Indiana, and by a bend pas¬ ses into this State, and its present entrance into lake Michigan is within 79 the State. It is, however, well known that its former entrance into the lake was in Indiana, and that it often has a discharge of its waters at the latter place in a particular stage of the waters of the lake. It is found by examination that the waters of Calamic must be raised by a dam near the mouth of Stony creek (or Rock creek) about six or seven feet, in order to feed a canal ; and if used for feeding with a copious supply of water, there should be a descent of at least two inches in each mile. This would increase the height of the dam to nine feet nearly above the present sur¬ face of water. The effect of such a dam would be to make back-water, for many miles, into the State of Indiana; and when we look at all these facts, it is an undeniable truth that the waters of the Calamic are not the "legitimate waters of the State of Illinois." To get feeding waters for a canal on a high level, we must therefore look to Fox river. Before my arrival in this State, your Board had very judiciously and properly directed Capt. Burnett, with his party, to examine the country between the Fox river and the Des Plaines, beginning at the point on Fox river near Elgin, where former examinations had ended, and extend north to the line of the State. Capt. Burnett's report on this survey is now herewith annexed, togeth¬ er with a sketch of the topography of the country, and which gives a very satisfactory account of what resources of water can be obtained from Fox river. The next feasible plan of obtaining water from Fox river is from a gointinPistaka lake, six or eight miles below the State line ; and thence by a cutting designated by a red line on the map, to let the waters of Fox river into Mill creek, a branch of the Des Plaines; and from thence let them follow the bed of Mill creek and Des Plaines for forty or fifty miles before they arrive at the canal where they can be received into it. By the plan proposed by Capt. Burnett, (and which I fully approve) a dam is to be erected across Fox river to raise its waters two feet only, (as that is all the descent in the river from the State line to the proposed dam;) a cutting, rising from nothing to 53J feet, is then to be made for 12^ miles. This cutting appears by Capt Burnett's report to be fair, and without rock. The amount of excavation for a cut sixteen feet on the bottom, and slopes two to one, with the water four or five feet deep, (and it then would be a doubtful question whether it would pass through the quantity required,) with the proposed descent of three inches per mile, admitting that it would discharge the quantity required, the cost would be thus: 3,176,520 cubic yards, at 30 cents - $952,956 Dam across Fox river (on bad bottom) - - 20,000 Contingencies, engineering, &c..5 per cent, (say) - 45,647 $1,018,603 We have here an outlay of more than one million of dollars. Capt. Burnett estimated the rise of water in Fox river, above its lowest state, at two feet, and by measurement he found the stream gave 25,000 cubic feet per minute. If we take half of this quantity as its minimum, at the 80 lowest water, we allow all that it will give, and perhaps more, 12,500 x 60 = 750,000 per hour. As this water has to run, probably fifty miles, in the marshy bed of the Des Plaines and Mill creek, where it is very sluggish, and will be several days in reaching the canal through Mill pond, &c., it is not too much to say that we might lose one-fourth of it by evaporation in a severe drought and hot sun. In this calculation I have supposed the whole of Fox river in its lowest state to be brought through. Now we cannot expect that we shall have a perfectly tight dam; we shall lose much there; and as we have only 750,000—187,500=562,500 x to 54,800 equal to 617,300 cubic feet of water from both these rivers, and we want certainly 500,000 feet ; and upon the most favorable calculation, we have only the 617,300 to rely up¬ on. It is true this quantity might be increased considerably by making reservoirs of several little lakes at the head of Mill creek. If we admit that an ample supply can be obtained from this source, we ought, before adopting the plan, to look at the consequence of taking the waters of Fox river, and what would be the effect of throwing so much water into the bed of the Des Plaines. Would it not prevent the sever¬ al large tracts of low (very low) prairie land from being drained, and brought under cultivation? If I have been correctly informed, this would be the effect; and this is of very great moment, not only in preventing this land from being cultivated, but endangering the health of the people in the surrounding country. The great objection to this immediate section of country is, that the lands do not drain freely; and for a permanent work, like the Illinois and Michigan canal, all the plans should be adopted, in reason, to make every part of the land more valuable by the drainage which the plan and the construction of the canal may give. The Illinois and Michigan canal, as now projected, and under construction may truly be considered as one of the greatest and most important, in its consequences, of any work of any age or nation. In looking over this connection between the lakes and the Mississippi, it is no doubt superior in its advantages to any other which can ever be farmed. It is the shortest artificial work, with the least lockage. The climate, soil, and the capability of productions of the coun¬ try which will be benefitted by the construction of this work, will cer¬ tainly equal, if they do not exceed, any other part of the United States; and when I view it in this light, I think it justly merits to be executed upon the best and most permanent plan, and will justify, by its revenue, any outlay which may be put upon it in reason. Taking a view of the whole ground, and looking at the probable cost of the deep cutting, of the low level, and the length of time it will take to accomplish it, and the time the country will lose the benefit; looking, also, at the great good to the country, and the pecuniary advantage to the State and the canal, by the creation of water-power at Lockport, and Ju¬ liet, I have no doubt upon my mind that the present plan of cutting dowrn the Summit, so as to draw feeding water from lake Michigan, ought to be continued, in preference to any other which I can suggest. In my remarks I have not entered into calculation to show the many expenses and losses whi :h would result from raising the level ten feet— such as the extra lock keeper, annual repair of locks, loss to the country and State, by not having water-power—the advantages of vessels of large 81 size reaching Lockport before unlading, or lading—these and many other considerations have a bearing upon this question; and I might say would admit the case to be stated by putting down the expense of the low level, and then deducting the additional value given by water-power to the State property at Lockport and Juliet, and the drainage of the State land otherwise, on one side—and on the other, the cost of the high level, with two locks—the cost of the attendance (brought into capital)—the cost of introducing Fox river, and other contingencies—such as damages for the injury done to lands along the Des Plaines; and I fully believe the balance would be in favor of drawing the feeding water from lake Michigan. In these remarks and opinions, 1 believe I have fully complied with the act directing the appointment. I shall, however, in another communication, comply with your wishes ill regard to the details of the work, in its location, arid the various points of difficulty in construction, and make full remarks upon every point. Respectfully submitted by Your obedient servant, BENJ. WRIGHT, Civil Engineer. Chicago, III., October 20, 1837. To B. Wright, Esq. Civil Engineer. Sir: In compliance with a law passed by the Legislaturë of Illinois, and approved March, 1837, I have been instructed by the Board of Com¬ missioners of the Illinois and Michigan canal to examine the dividing ridge of the Fox and Des Plaines rivers, withih the limits of this State, to ascertain the most eligible route for conveying the waters of the Fox river to supply the Summit Division of the Illinois and Michigan canal, and to report to you for your consideration the results of that exam¬ ination. The variety of opinions entertained upon the feasibility of this mode of feeding the Summit Division, and the great importance of the subject, has led to the examination of many summits, which a reconnoissance alone mighf have pronounced impracticable. In ascending the Fox river, the first summit met with, having a con¬ siderable depression, is that of Popple creek, which empties into the Fox, about one mile below Elgin, and has its rise with the head waters of the Du Pagë; thence the depression is continued by the western branch of Salt creek, and Salt creek itself into the Des Plaines. This summit was thoroughly examined last year, and by reference to the level obtained, found totally impracticable. The depression of Lake and Flint creeks, discharing their waters into the Fox, and having their rise with the head waters of the northerly branch of Salt creek, Buffalo creek, and Indian creek, three branches of the Des Plaines river, were next examined. By these depressions a sum¬ mit cannot be obtained of less than ninety feet above the surface of the Fox at the mouth of Flint creek. The next depression examined was that of Slocum's and Bang's lakes, F 82 which head in extensive sloughs opposite to the head waters ol the northerly branch of Indian creek. This route presents a summit ridge of about I(jO feet, above the surface of the Fox, at the outlet of the lake. The summit of the southerly branch of Deer, or Squaw creek, was next examined, so far as to show an elevation above the Fox, at the mouth of said creek, of 20 feet, when it was discovered that it takes its rise near the head waters of Indian creek, which were known to be too much ele¬ vated for our purpose. The summit of Round lake, which is one of a chain of lakes discharg¬ ing themselves into the Fox at a point about six and a half miles from the State line; and Fourth lake, one of another chain forming the southwes¬ terly branch of Mill creek, which discharges itself into the Des Plaines river, at a 'point about five miles below the State line, was next ex¬ amined, and found to be, at the close of our examinations, the most favor¬ able route. The next depression examined was that of Silver creek, which discharges itself into the Fox river about two miles south of the State line. This depression connects itself with Silver lake; then crossing a high ridge about three quarters of a mile, descends, by a broad slough, to one of the lakes which form the northerly branch of Mill creek, and by said creek to the Des Plaines river. This route would be the shortest of any, being estimated at about one half mile shorter than the Round and Fourth lake route, but the difference in level of the summits of these two routes is so decidedly in favor of the latter that a further comparison is deemed unnecessary. There is still another depression, of which Cross lake, immediately upon the State line, is the summit. The surface of that lake is 74.385 feet above the present surface of the F ox at the State line; and in following the depressions connected with it, if it were practicable or desirable to do so, we should be compelled to go beyond the limits of the State. The most favorable route for passing the dividing ridge having been as¬ certained, the valley of Fox river was examined, from the State line down¬ ward, with reference to guaging the discharges of the river, and selecting the most eligible point for a dam. The surface of the river at the State line was supposed to be, from the best information to be obtained, about 2 feet above its lowest stage, and L75 below its highest, and to discharge, at the most favorable point for gauging, more than 25,000 cubic feet per minute. From several miles north of the State line, the river has but lit¬ tle fall, and south of it, it has only descent of about one and a half feet per mile for one and a half miles, when it loses itself in the Pistaka lakes, which to a great extent are filled with a floating sag, high grass and wild rice. The waters of the Fox, after passing through these lakes, and receiving the Nepusink and other branches, emerges from the most southerly of the group, with a clear, deep, and distinct channel, being at the outlet about 330 yards wide, and from three and a half to nine and a half feet deep. The most eligible point for a darrl is believed to be at the Indian grave, three quarters of a mile below that point The river there is about 220 yards wideband from five and a half to seven feet deep, with a light gravel and sandy bottom; the west bank is abput thirteen fee thigh, the east bank con¬ sists of a high knoll, connected with the main ridge by low ground, which is about thirty-five yards wide. In case a dam should be located upon this site, an embankment will be required across this low ground. The de- 83 scent of the waters of the Fox to the outlet of Round lake, is 6.150 feet. The estimated descent to site of dam, two miles further south, 7.500 feet— on account of the very slight descent of the waters of Fox, within the State limits, and the low nature of the country in the vicinity of the Pistaka lakes. The surface of the most easterly ci these lakes is assumed at two feet only above its present level at the outlet of Round lake, where it is proposed to take out the water for the feeder. An experimental line has been run from this point across the Round lake and Fourth lake summit to the mouth of Mill creek, on *the Des ' Plaines river, to ascertain the amount of excavation necessary to accom¬ plish the object of the survey. The Des Plaines river was found to be 75.500 feet below the point of commencement, and the summit or deepest cutting to be 53.305 feet; and the length of said line before the waters of the feeder could discharge themselves into the Des Plaines river, by the valley of Mill creek, is 12 miles 696 yards. An estimate of the quantity of excavation necessary has been made from the data of the dimensions and declivity that you recommended, viz: sixteen feet bottom, slopes of two to one, and a declivity of three inches per mile, and was found to be about 3,176,520 yards. The only indication of rock observed in the survey of this summit was occasional detached pieces of silicious lime rock. About one half mile of the line below Long lake pas¬ ses through a marsh which it will be difficult to drain, and about one mile and a quarter is located in the beds of Round and Fourth lakes. All which is respectfully submitted by Your obedient servant, WARD B. BURNETT, Resident Engineer Illinois and Michigan CanaL Lockport, Illinois, November 30,1837. To the Board of Commissioners of the Illinois and Michigan CanaL In the prosecution of surveys in the vicinity of4 Fox river, authorized by the Legislature of this State in March last, I was instructed by you to make such an examination of the nature of the valley of that stream, within the State limits, as would be useful in determining the most feasible manner of improving its navigation. In compliance with these instructions, a continuous compass and level line was run upon or near the banks of the Fox, between the navigable feeder of the Western Division of the Illinois and Michigan canal, at Green's mills, and the State line. This preliminary survey was made in the latter part of the month of October; and, as my party have been almost exclusively engaged since that period upon other estimates and plans, it has been impossible to prepare those belonging to the Fox river in time for your annual report. The maps and estimates are now commenced, all df which will be presented with my report, as soon as they are completed. In the meantime, as it may be thought desirable to know the general results of the survey and the feasibility of its object, I have formed from 84 our field books a condensed statement of the difference of level of the sur» face of the Fox, at those points of the river the most known, with their respective distances from each other, and the point of commencement. The surface of the Fox, at the time of the survey was, from the best in¬ formation to be obtained, from one and a half feet, in the most rapid por¬ tions of it, to two and a half feet in the more sluggish above low water ; and from one and three-fourths feet to three and one-fourth feet, below high water. The following statement of levels has been made out from the surface of the proposed feeder-dam at Green's mills, taken at zero; and the dis¬ tances are such as were obtained by the survey; to which, as the river v banks were not meandered closely in some distances, should be added about four miles, in order to obtain the whole length of navigation required.

The difference of level of its surface in the whole of that distance is 262.405 feet; and with reference to the foregoing statement, it will be seen that the most of this difference is found from and below the village of Charleston, almost all of it being below a remarkable contraction in the width of the river, called "the Narrows ;" above which therë is little fall. Thus we have three divisions of the river that differ essentially in their descent—the first having an average difference of level at the surface of about 3.6 feet, (and in some cases 5 feet per mile;) the second of 2.2 feet per mile ; and the third an average of 0.87 feet per mile. These divisions differ from each other almost as distinctly in the nature of their banks— the first having them abrupt, and occasionally of high bluff rock; the second having them very favorable for a tow-path; and the third, includ¬ ing the Pistaka lakes, having a great extent of low marsh upon either bank; on which, for a great distance, it would scarcely be possible to con¬ struct a tow-path. | This variety in the nature of,the banks of the Fox and its descent is such that more consideration is required for the arrangement of the par¬ ticular parts of its proposed improvement; and in order that a nearer ap¬ proximation may be made, by estimate, to the expense of this important work, than the results of a preliminary survey can afford, I wish to visit some points of the river again, before making my report. Without further examination, I believe the most feasible plan for the contemplated improvement is that of slack-water navigation, with a tow- path upon the most favorable side of the river, except in some places, where it will be advisable to construct short lines of canal. All of which is respectfully submitted by Your obedient servant, WARD B. BURNETT, Resident Engineer III. and Mich. Canal. 87 IL Chicago, Oct. 25, 1837.

Gentlemen: Having passed over the line of the canal from Chicago to Peru, and obtained, through your chief engineer, a knowledge of the plans of the intended works of art, as proposed by him, as also the various plans intended to be pur¬ sued in the execution of the very expensive parts of the excavation, and security of certain points,—I now take pleasure in complying with your request in an¬ swering various questions in relation to the work. 1st. Will a guard-lock be necessary at Chicago river? I do not think I should build any guard-lock. If I understand this case correctly, the use of a guard- lock would be to shutout the water from the lake. If, as a precaution for safety, to guard any part of the 30 miles summit, it should not be so far distant from the locks at Lockport. The mile or two next to and above the locks at Lockport, is the only place' where any breach can happen in this level, and that can be secured better than by a guard-lock so far off as 30 miles. There are various plans for securing against any breach in the embankment at Lockport, such as the following: Select a place of rock cutting about 10 feet deep, as near to Lockport as can oe found, where the rock lays close, and as few fissures as possible —contract the canal to 30 or 35 feet thus: Tow-path. Canal \ and leave a block of rock, as at a, ten or twelve feet high—cut the face c c with care, and place in gates, in the marmer as described to me by Mr. Talcott, and intended by the chief engineer, Mr. Gooding. These, if properly fixed to rest on the bottom until raised, will be ample security, and can be attended to instantly upon any appearance of a breach. Wickets should be made in one of the gates, and a timber may be thrown across for the top of the gates to rest against, if ne¬ cessary. If the Board do not choose to make the gates, a heavy timber of 15 in¬ ches square, laid across, and plank 4 inches thick put down on the bottom of the canal, at an angle of 45°, with a little straw and fine stuff placed above, would stop the water in 2 hours. A waste-weir has been projected of 500 feet long, at some proper point, (say where the rock cutting is about 4 feet,) and build good masonry with water ce¬ ment uppn this rock, to the top water line; and in order to have additional security, I would have a number of gates placed in the masonry, that could be raised, and let out water very rapidly at pleasure. The value of the water-power at Lockport will be in demand as soon as the water is in the canal; and to prevent breaking the bank to take out water, I would advise that a water cement wall be built, with the stone excavated from the carlal, founded on the rock, and carried up with a batter of one inch to the foot; and at every 60 Or 80 or 100 feet, I would insert a cast-iron frame of various sizes, say some of 24 inches square, 20, 18, 12, or any other size, I supposed would be re- o o cv pb c CO o q co C a 88 quired, and these being placed at 2 feet or more above the bottom of canal, and masonry extended behind 10 or 20 feet as you please, and a gate fitted to each. I should do the same thing at Juliet, where, if 1 have not mistaken the information obtained, the State holds control of all the water-power on the river. This will permit you to sell water-power at any point, and in such quantities as may be wanted, and the purchaser has nothing to do but erect his building and introduce his water; and you sell the water by the inch as is customary. This wall, with the earth behind it, is a great additional security to the bank, and the water is more desirable from this security. I would advise also, as a precautionary security, the leaving a bar of earth at Chicago river, of SO feet wide; and when the water is let into the canal, I would only take away 25 or 30 feet wide. I would not fill the summit level with the water from the Chicago, but let it fill slowly from other streams, before 1 broke this bar of earth; this can be removed by a dredger. 2d. Will a slope wall be necessary through the earth excavation of the sum¬ mit? w If the earth proves to be all of the quality of section No. 1, and others I have seen, I would on no account have a slope wall. Such wall, below the surface of wa¬ ter, is very injurious to boats if the}^ strike it; and if any wall is required, it can only be to protect the bank above water, and that can be made, when the water is in the canal, very cheap. I believe,, with the soil in this cut, vegetation may be made to grow upon it, and then the frost and rains will not disturb it much, and no wall will ever be needed. 3d. Will it be necessary to cut down the towing-path? I would by no means advise cutting down the towing-path; only add 50 to ICO per cent, to the length of the tow rope, through the earth cutting, and the trackage is easy. By being so high, the horse is in a cooler atmosphere, and is not so likely to be thrown into the canal at the rock excavation. The Board may find it useful to make places in the rock in the form of steps, where a horse may be taken out, if by accident he should be thrown in; and I see no great or even any important benefit by cutting down. 4th. Is the present plan of drainage a judicious one, and what difficulty may be anticipated from water, in excavating the summit? The greatest difficulty in working this division, is the water, beginning at Chicago river, and from thence to the end of section 15. If I have understood the plan of the chief engineer, it is his intention to have a large ditch outside of the spoil-bank, on the upper or southeast side, and this to be extended, as now partly done, to the south branch of the Chicago. It may perhaps be found that some of the sections near the Point of Oaks do not drain freely by this ditch; if so, then they must be drained across the canal. À guard-bank of earth must.be raised along the north side, to keep out the water from the Des Plaines river and from the prairie. These precautions will keep out surface water, which is nearly all they have to contend with on this part. From the Point of Oaks, on section 15, to section 45, is the most difficult part to drain. Many of the sections, from 15 to 39, will drain across the canal, and bank oat the water of the river and marsh at first, in pieces or parts of their work. But in order to drain this part, from 15 to 45, effectually, a very large drain, nearly or quite the size of a 40 feet canal, should be cut, from section 42 or 43, and extend eastward through the whole Saganaskce swamp, to Stoney creek., This must he cut 3 feet at the canal, and 8^ feet deep at the summit of the swamp, 5 miles east of canal, and then continue 7 or 8 miles further, before it will find a free discharge; the water having so far to run, must have a large bed, as there will be a great collection of water in heavv rains. O «■ • 89 If the Board could feel justified in laying out a canal, and excavating it regu¬ larly, 28 feet on the bottom, it would not do more than take off the land water between sections 16 and 45, which must all pass out this way- unless it is passed across the canal, and that will be very difficult at times; and at finishing the work, a large and regular ditch must be cut on the upper side of the canal, from section 15 to the proposed ditch in the Saganaskee swamp. This must be outside of the spoil-bank, a guard-bank placed on the lower side, also a ditch from section 45 to section 42. I cannot urge too strongly upon the Board the very great, importance of hav¬ ing a very large drain through the Sag swamp. It is vitally important to the pros¬ ecution of the canal successfully; and its whole cost, if made as I have recom¬ mended, will be saved in the ease with which the water will be taken off from the work. From section 45 towards Lockport, a drain is to be made; the upper side is now going on; (this is right.) I have been particular in describing ail these drains; they are, however, only recapitulating the plans of your engineers, ex¬ cept as to size, and which 1 think judicious. 5th. Are the contract prices for the work, as let on the canal, sufficienf to finish it? I think all the contracts I have noticed are let at what I should consider very high prices. It is true that I ought not to compare prices given for work in the Atlantic States with this, because of the great difficulty in obtaining labor and provisions here; as to the latter, it will be growing better yearly, and so will the pffce of labor be reduced before the completion of this work. If contractors cannot sustain themselves with their contracts, it will be for want of good management. 6th. 66 The size of the locks proposed for the Illinois and Michigan canal is 18 by 110 feet in the chamber. Do you think this the proper size of locks for this work?" I do not think I can suggest any improvement in the size of the locks; it is the best possible. It will carry a boat with 150 tons of lading if required. The loca¬ tion of the locks at Lockport I think very judicious and good; and the plan of en¬ tering the Des Plaines above Juliet I think right, after making dam No. 1 on State property above the present village of Juliet, and passing down to dam No. 2. I should then, in both cases, make my lift-lock walls so high as to be a guard- lock. I should only have two dams at Juliet. The line is then plain to the Du Page, and passes that river on an acqueduct, and then passing over pretty fair ground till we reach the Kankakee bluffs. In my examination of these bluffs, which have been considered as presenting great difficulties, I think your engi¬ neer has proposed locating his line well and skilfully, in keeping so far from the hills as to give it a chance to slip without coming into his canal. I do not believe there will be any difficulties which will not be easily overcome, Around these bluffs your engineer has estimated a much larger quantity of slope wall than I should use in that work; (perhaps I maybe wrong.) Passing on, the canal is to cross the Au Sable river, in a pool formed by a dam, requiring a guard-lock on lower side. The line pursues a plain route of good location to Fox river, over which it is to pass by an aqueduct. The plan of the aqueduct, if built of wood upon stone piers, is all right, and the location cannot be improved. Here it is proposed to take a feeder from Fox river, about four miles in length. After examining the ground on the two lines run on west side, in company with the chief engineer, I should give my opinion that the short line with the deep cutting ought to be adopted. If hydraulic power can be obtained at Ottawa, through a branch canal to be made for the accomodation of the village, and to lock down into the Illinois, I would locate it at right angles with the main stem; and as soon as I left the main line, I 90 would lock down 5 or 6 feet to the level of the plain, and carry that level through at any poini between Clinton and Fulton streets, making large basins one or two blocks north of the land now sold and occupied. After bringing the canal to the line of the street, below all property sold by the State, I would carry a mill canal along the south side of the street towards Fox river, and place cotton, woollen, or other factories requiring steady power, below this canal, giving them 15 or 16 feet herd and fall; then leaving a space of 200 feet (more or less,) I would have canal No. 2, parallel to the other; and on this, I would sell water-power for works not requiring steady power. The line then, after passing over good ground for many miles, reaches Camp rock and Pecumsagan, and Little Vermilion, all which it passes very well; and although some little expense will be required in lining and. puddling the porous rock and earth, there is no doubt the location is well rpade. In relation to the termination by a steamboat canal and basin of large capaci¬ ty, together with a canal boat basin between the two locks, I think the whole plan is excellent, in relation to the business of the canal and the prosperity of the State, and I do not think I can suggest any improvement. If I should make any remark in relation to the work and plans upon this ca¬ nal, it will be to substitute stone aqueducts in place of wood over Fox river, Du Page,Vermilion, and other smaller streams, where wooden trunks have been pro¬ posed, more particularly Fox, Vermilion, and DuPage; these being large and important works of art, they ought to be built with stone arches, if stone of good quality can le obtained. I see there is difficulty in finding good durable stone in the country. I saw some good ones about Peru, and perhaps the same strata may be found in the hills at or near Ottawa. I would by no means advise to build of bad stone. A wooden trunk, upon stone piers is better than a structure of stone that will soon decompose. * If good stone for the cut work, and particularly the arches, could be found 50 or 100 miles below, and near the river, they could not be very expensive to trans¬ port at a proper state of the river; all the stone for the dead work might be found at hand. If your Board cannot find good stone for locks, it will be very unfortunate. These structures should be done in thé best manner, and laid with the best of wa¬ ter lime. I shall send Mr Gooding a sketch of the latest improvements in locks. I presume it will be some time before the Board will offer contracts for locks, and in the mean time, stone of .good quality may be found , it is to be hoped. In reviewing the whole line of this proposed canal, the location of it and the plans proposed to overcome all the difficulties, I cannot award too much praise to your engineer. He has shown skill and sound judgment in every part of the line, and I do not think the plans he has laid down for the prosecution of the work can be improved upon or made better with the materials so far discovered. I have the honor to be, Gentlemen, vour obedient, BENJ. WRIGHT. 91 J. Locktort, Illinois, November 28, 1887® To Wm. Gooding, Esq. Chief Engineer Illinois and Michigan Canal. Sir: I have the honor of presenting to you the data, map, and estimates of the survey of the Saganaskèe swamp—Grassy lake—Stoney creek—and the Calumet river, to the State line, made by my party under your instructions in July last, with reference to the proposed connection of the Illinois and Michigan canal with the Michigan and Erie canal of Indiana. Agreeably to your directions, the survey was commenced at the mouth of Stoney creek, upon the Calumet river, and continued up that stream to the State line, with a view of locating as high a dam near the point of com¬ mencement as the nature of the stream and its banks would permit,' in order to create a pool for canal boat navigation from the State line to said dam, as well as to enable us to pass the summit of the Saganaskee swamp, with the waters of the Calumet, upon the line of the proposed Illinois and Indiana canal, with the least possible cutting. This line of river and ca¬ nal navigation completes the proposed connection within the limits of the State. When the survey was made, the streams were very much swollen by rains, and I was informed that the Calumet was seldom, if ever, known to be higher than at that time. The distance by the left bank of the Calu¬ met river, from the point at which the dam was afterwards located to the State line, was found to be about twelve miles ; which will be lessened by the plan of improvement to eleven and a half miles, by clearing and changing the direction of that bank. The surface of water at the mouth of Stoney creek was found to be 0.820 below. The base line of level was assumed at 11.500 above the bottom of the Illinois and Michigan canal at lake Michigan, or 5.500 above; the lowest surface of the lake at the pro¬ posed site for dam, 0.500 below; at the old Indian ford, 2.087 above; at the State line, 5.772 above ; and at a point abové Gibson's bridge, and about two and one-third miles, in the State of Indiana, 7.867 above. The banks of this river are very uniformly about 8.500 above, so that in Indiana, above where one level liile terminated, they were overflown by the ihgh stage of water to a very great extent. These examinations made, the site of the dam was located about sixty ' chains above the mouth of Stoney creek, as indicated upon the accompa¬ nying maps, and its height placed at 4.000 above, that being considered the highest that could be safely adopted with reference to the foregoing levels, and the low nature of the banks of the Calumet, and much of the surrounding country. The width of the river at this point was found to be 295 feet from bank to bank; and the average depth of a cross section of the stream, to the base of the foundation for the proposed dam, was fixed at seven feet; so that the average height of the dam (which has been as¬ sumed at 4.000 feet above the base line,) will be 11.5 feet. The foundation is gravelly and probably based upon a bed of lime rock. A dam of this height will elevate the surface of the river, at the State line, to about 5.500 above, at the lowest stages of the water, and to about 6.500 above, at the highest; allowing one and a half inches per mlie for back-water during the lowest stage, and two and a half inches in the highest. 92 The right bank of the river is the most uniform, being indented with but few sloughs, as its drainage runs chiefly into the Big Calumet, which lies directly behind and parallel to it, whilst the left bank is broken by many, requiring embankment and tow-path bridges. It is believed, how¬ ever, that the expense of tow-path bridges to cross the Calumet above and near the dam, and to recross, as would be advisable in the first case before reaching the State line—and the additional expense pf grubbing upon that bank, together with the fact that the tow-path would then be upon the least productive side of the river, are considerations that will jus¬ tify its location upon the left bank, at the expense included in the accom¬ panying estimate. In the location of the Illinois and Indiana canal, but one route was adopted, except for a short distance, in crossing from the Calumet to the valley of Stoney creek, for which distance two routes have been estimated. The shortest leaves the river 34.72 chains above the dam—the longest 18 chains above, and they both unite at station 19 of the longest line, at distances of 47.07 chains, and 57 chains, respectively, from the river. A guard-lock has been estimated, for either case, where these lines leave the river. The first line is, including 16.72 chains river navigation, 26.65 chains shorter than the last. From the junction of these two routes near Rexford's bridge, the line follows up the right bank of Stoney creek, passing eastward of Lane's island, and to the left of Grassy lake, (an ex¬ pansion of Stoney creek) to the Saganaskee swamp, over which it then runs from a point of Lane's island to the mouth of Paddock's brook, the main tributary of Stoney creek; thence continuing about 65 chains, to the Calumet and Des Plaines summit of the Saganaskee swamp, it follows the depression of said swamp, which descends almost uniformly to the line of the Illinois and Michigan canal, with which it connects, by a lockage of 11.25 feet, at the distance of 15 miles and 60 chains from the point of com¬ mencement. In construction and at a more favorable season, the line may be straightened, and made somewhat shorter, by throwing it further from the shore into Grassy lake. The dimensions adopted for the canal were twenty-six feet bottom, and forty feet at top water line—four feet deep—slopes of one and three-fourths to one. No declivity has been al¬ lowed. These dimensions are those proposed for that portion of the con¬ nection which is to be constructed by the State of Indiana. The bottom of Stoney creek at the outlet of Grassy lake, or first ripple of Stoney creek, is about 0.500 below; the Des Plaines and Calumet sum¬ mit of the Saganaskee swamp, as the line is located, is 9,500 above; and the point of junction with the Illinois and Michigan canal is about 3.25 above. A second route was examined, diverging from the first, at station 41, and following a deep slough to the old Sag bridge, westward of Lane's island, thence descending that branch of the Saganaskee swamp which receives its water from Bachelor's grove &c., (tributary to Stoney creek,) it unites with it again at station 296, near the summit of the first line. This route would give us a second summit to pass, that is higher than the first, with rock cutting to a very considerable extent, whilst the dis¬ tance saved would not much exceed one mile. The exavation of the line adopted is estimated to contain hardened clay, but no more rock, it is believed, will be met with than is included in the small item of the accompanying estimate. It should be stated, how- 4 93 ever, that on account of the great depth of water upon the Saganaskee swamp, at the period of the survey, it was not possible to test the nature of the excavation, from the summit to the turnpike, in a conclusive manner. All of which is very respectfully submitted by Your obedient servant, WARD B. BURNETT. Estimate of the stone work of abutments, guard-lock, tyc., is estimated, upon the ground that the stone may be transported upon the prism of the canalfilled with the drainage of the country, from the vicinity of the Illinois and Michigan canal.
