GUYER. 1839 v V v* CP It* Oi P? report. Mr Strohm, from the committee on roads, bridges and inland navi- gation, acting under the resolution of the Senate passed on the twenty-fifth day of March last, which authorized them to send for persons and papers, for the purpose of enquiring as to the amount of money actually necessary for repairs upon our different finished lines of canals and rail roads, and to ascertain the amount of money ac¬ tually due for repairs and materials furnished for repairs; and whether any supervisors have unsettled accounts, and whether they have procured authenticated vouchers, without paying the amount due to laborers and others; and that they also have power to visit the different lines of public works andl employ an engineer to accompany them, made the following report, riz : That they have, during the recess of the Legislature, visited all the canals which have been constructed and completed by the Com¬ monwealth, and also the Allegheny Portage rail road. The time in which the committee were compelled to execute the dutv assigned to them, in order to enable them to attend to their legislative duties at the re-assembling of the Legislature, was too limited to permit them to make s«ch a minute investigation, and ac¬ curate detailed report, as would bfe desirable on the occasion. The season of the year, too, was unfavorable to the examination of some portion of the work—being a time when the streams are full, and the volume of water too great to admit of a careful examination of the condition of the dams, which can only be done advantageously, an with a degree of accuracy approximating to the truth, during the summer and autumn, when the waters, usually, are at the lowest stage, and when an occasional submersion can be endured without suffering disagreeable sensations or serious consequences. In esti¬ mating the amount necessary for repairing the dams, the committee 0 ;& 99.39 4 were obliged to rely on information obtained from persons acquainted with the particular situation, or adopt the report of engineers, founded probably on no better data. Upon reading the report of the Board of Canal Commissioners, dated March 11, 1839, your committee were struck with the anxious desire evinced, throughout that report, to impress upon the public mind the belief that, through “ negligence and inattention, upivards of one million and a half of dollars ” was necessary to render the public improvements “ adequate to transact the business which may and should be done upon them.” If this were the fact, it would be right that the Legislature, and the whole people should know it; but evidence of a contrary character, sufficient to satisfy your committee that the amount required for repairs was greatly exaggerated, had been developed before the report was printed, and a personal exami¬ nation has only confirmed what concurrent circumstances had pre¬ viously rendered evident. The sum of one hundred thousand dollars had not been expended in repairing the improvements, when your committee passed along the lines end found them in a condition (ex¬ cept in a few places that will be hereafter noticed,) to accommodate the most active business that has ever been transacted upon our canals. This, then, was indubitable evidence, that it did not require “ one million and a half of dollars , to render them adequate to transact the business which may and should be done upon them.” The committee found the Eastern division, commencing at the outlet locks at Columbia, and terminating at the outlet lock in the pool of the Clark’s Ferry dam, in good navigable order. On this line some repairs are necessary, but they are of no considerable magnitude, and may be effected without interrupting the navigation. The water-way near Columbia should be renewed, as the timber is very much decayed and scarcely susceptible of judicious repair. Some of the other water-ways on this line require some repairs. One of the piers at the aqueduct over Conewago creek has given way. It is now temporarily supported by posts, but the pier should be rebuilt at the earliest possible day. The aqueduct at Swatara re¬ quires considerable repairs, and those over Chicques, Conoy, Clark’s, Stony and Paxton creeks need some repairs. The aqueduct at Clark’s creek is the worst on this line; two of the piers will have to be rebuilt and the superstructure renewed. The abutments also require some repairing. 5 The locks on this line are generally in good condition. The upper outlet lock from the basin at Portsmouth to the Svvatara creek, is said to be defective at the foundation; this is not perceptible when the water is in, but the greater portion of the wall is straight, and seems to be permanent. A number of the lock gates are a good deal shat¬ tered, and require to be renewed during the ensuing winter, and probably may need some repair during the summer. Some of the bridges and bridge abutments stand in need of repairing, and*a few will have to be rebuilt. The canal banks, and especially the towing- * path bank, needs repairing in many places. Where the banks are composed of sand, clay, or alluvia]] earth, as is the case in many pla¬ ces, the agitation of the water is constantly washing it away, render¬ ing frequent repairs necessary, and requiring constant vigilance on the part of the public agents, to prtevent breaches which would cost considerable labor and expense to repair. This will continue to be the case, until those vulnerable parts of the canal banks are perma¬ nently secured, by a good slope wall or lined with timber. On this subject the committee will give their opinion in a subsequent part of their report. On this division of the canal a grpat proportion of the towing-path, and part of the berm bank, is supported by high vertical walls. These walls have, in many places, given way, and parts of them have fallen down. The security of the canals renders it necessary that those parts should be rebuilt without delay. The cause of this dilapidation at so early a period nay be ascribed, in part, to defects in the original construction, but in : of the materials used. A kind of ome instances, more to the quality slate stone, found along the banks of the river, the character of which was not well understood at the time, was used in the construction of those walls. Experience has shown that when long exposed to the action of the atmosphere, those stones, in some measure, decompose and crumble into small pieces; consequently, whenever this kind of stone has been used, the wall will inevitably sink and eventually.fall. The guard fence on the berm side of the canal is decayed, and in many places entirely pros¬ trated. This is an item not essentially necessary to the navigation of the canal, but is of great public utility, in promoting the security of those who travel the road immediately on the bank of the canal, which has been constructed by the Commonwealth in lieu of one heretofore enjoyed by the public, on the ground now occupied by the canal. It is therefore incumbent on the Commonwealth to keep 6 those guard-fences in a proper state of repair. The committee be¬ lieve that forty thousand dollars will be required on this line for or¬ dinary repairs, and completing those locks now in progress, two of which are nearly completed. JUNIATA DIVISION. From the outlet lock at Clarke’s Ferry to Hollidaysburg. This .division, from its present appearance, may, with the exception of the aqueduct near the mouth of Juniata, with proper care and a rea¬ sonable expenditure, be kept in good navigable order throughout the season. The aqueduct above referred to, is in a precarious situation. Two spans have been renewed, the workmanship of which seems to be very substantial and well executed. The remaining four spans are much decayed, and at the time your committee passed, a portion thereof had sunk so much that it became necessary to draw off the water and repair it. It is now supported by posts, placed under it, and so long as those remain, the navigation may probably not be in¬ terrupted; but should a freshet in the river sweep away those sup¬ ports, portions of the aqueduct would, in all likelihood, sink so much as to render it impassable for a time, or perhaps make its immediate reconstruction unavoidable. Your committee agree with the engi¬ neer, that “ the materials for renewing it should be provided and framed, in readiness to be put up next winter, or sooner if necessary.” This has in part been done. The remainder of the aqueducts, the locks, lock gates, waste weirs, culverts and bridges, may be pro¬ nounced in tolerable condition, and not likely to need more than the usual ordinary repairs during the season. The committee are of opinion, that the estimate for repairs on this division, as made by the engineer, is most extravagantly high. Indeed, the very language of the report seems to evince a disposition to cavil and find fault, rather than to give a candid opinion and a reasonable estimate of the amount required for all necessary and judicious repairs. The extraordinary character of this report, induces the committee to advert particularly to some of the items which compose the aggregate of two hundred and thirty-two thousand dollars, said to be necessary to put this line in complete navigable order. Fifty-three thousand dollars is put down for rebuilding aqueducts on the present plan, including two spans, then puiting in at Duncan’s Island, and an additional sum of fifty-six thousand dollars for widening thirteen aqueducts to thirty 7 feet in the clear. Towards the construction of the two spans in the aqueduct at Duncan’s Island, a specific appropriation of fourteen thousand dollars has been made, a sum nearly sufficient to renew the whole trunk of the aqueduct; it is composed of six spans, two of which have been renewed at an expense of two thousand four hundred dollars each, at which rate, the whole would cost only four¬ teen thousand four hundred dollars, being but four hundred dollars more than the appropriation already made. Independent of that, the committee cannot conceive that any thing like the sum mentioned will be necessary for rebuilding aqueducts. The additional sum re¬ quired to widen aqueducts is, in a great measure, superfluous. For, though it may be advantageous to have the aqueducts widened, and may be proper to do so where rebuilding is actually necessary, the committee are satisfied that very few (if any) of the aqueducts on this line, are in a condition to justify such an undertaking within the pre¬ sent year, and therefore the sum of ninety-four thousand dollars may safely be deducted from those two items. The amount required for road, farm and tow-path bridges, and for repairing and building locks, lock gates, and waste weirs, seem to have been estimated upon the same high-pressure principle, and may safely be reduced more than twenty-five thousand dollars. The sum of forty-six thousand two hundred dollars is estimated for cleaning out pools at Hollidaysburg, Frankstown and Canoe creek, and for cleaning out canal and raising and clearing towing-path. The amount required for cleaning out the canal, your committee had not anjopportunity of ascertaining, as the canal was filled with water; but, from the great facility with which heavy laden boats pass and repass, the committee are strongly in¬ clined to believe that this too has been greatly exaggerated and might without risk of stinting the appropriation, be greatly reduced. The committee believe that the sum necessary for repairs on the Juniata division is about eighty thousand dollars. i PORTAGE RAIL ROAD. The committee found the Portage rail road in good order, so as to admit the transportation of all the passengers, produce, merchandize, coal, &c. &c. during the most active business season of the year, without difficulty or delay. Some repairs are necessary and always will be on such an improvement, but the committee are of the opin¬ ion that on the road alone, exclusive of the amount required for 8 additional depots and repairing engines, one half of the amount esti¬ mated by the engineer on the first of February last, would be suffi¬ cient, at this time, to make the necessary repairs for the balance of the season. How much has already been expended, since the engi¬ neer’s estimate was made, the committee have not ascertained; some of the timber on the inclined plane is decayed and should be replaced with new timber. This, in a country where timber can be obtained at a very low rate, will be cheaper, at least so long as the iron bars are good, than to lay those planes with T rails. In regard to the amount necessary for the repair of engines, your committee made neither examination nor estimate, not deeming themselves competent judges of those matters. The viaduct at Hollidaysburg needs some repairing, and the plan suggested by the engineer, to make additional passages for the water, should be adopted. The committee estimate the amount necessary for repairs on the Portage rail road, at twenty- five thousand dollars. WESTERN DIVISION. This division, with the exception of a few of the locks and dams, was in excellent order when the committee passed along. In some of the locks the mortar has been washed out, and consequently the water passes freely between the stones, and in one or two instances entirely through the banks; but the walls appear firm and substan¬ tial—the injurious leakage may be prevented at a slight expense. The dams appear to be in perfect repair, but the committee were in¬ formed by persons who had opportunities of knowing their true situation, that some of them require cribbing and gravelling. The committee, for reasons already given, do not pretend to accuracy in this particular. Some of the bridges, waste weirs and lock gates require repairing, and some will have to be rebuilt. The amount required to keep this division in good repair during the season, and make the necessary repairs during the ensuing winter, unless some unforeseen accident should render more necessary than can now reasonably be anticipated, will not, in the opinion of the committee, exceed thirty-five thousand dollars. REAVER DIVISION. Some of the locks on this division require repair, of which the heaviest item will perhaps be at the out-lock at the Ohio river. This 9 lock was originally located to accommodate the canal at a low stage of water in the river; consequently, at any other stage, it is rather too low, and liable to receive a deposite of sand, which renders it diffi¬ cult to be kept in good working order. On this line there are seven dams, which at present seem to be in tolerable good condition, but which, in reality, from the best information the committee could ob¬ tain, require considerable repairs. From Beaver to New Castle the towing-path is reasonably good, as are also the aqueducts, except one near New Castle, which is in a dilapidated condition, and needs a good deal of repairing. The piers of the towing-path bridge, at the mouth of Conneque- nessing creek, have been injured by ice and driftwood, but not so materially as to render its reconstruction necessary ; with compara¬ tively slight repairs, it may stand for several years, unless farther in¬ jured by extraordinary freshets. The towing-path above New Cas¬ tle has been very much injured, and in some places entirely washed away. The towing-path in many places has always been too low, and will constantly be subject to overflowing unless raised to a greater height. A part thereof has already been repaired, and other por¬ tions were in progress when the committee visited the line. The present navigation terminates at Western Reserve Harbor, four miles above New Castle. On the remaining two miles, the banks being composed principally of light sandy loam, easily affected by the agi¬ tation of the water and yielding to the friction of the current, the towing-path has been entirely destroyed. Your committee would deem it unwise to expend any money on that part of it during the present season. It is utterly useless until the Shenango line is com¬ pleted, which will probably not be under two years, by which time the labor and money now expended on this portion of the towing- path, would be very likely to be all swept away again. The committee estimate the cost of repairing the Beaver division, at thirty thousand dollars. i FRENCH CREEK FEEDER AND FRANKLIN LINE. The feeder dam above Dr. Bemus’ mill, has in part been swept » away, and the remainder so much injured as to render the rebuilding of the whole unavoidable. In addition to this, a considerable portion of the mound between the dam and the guard lock, and which in fact constituted part of the dam, has been swept to the foundation, 10 and several feet below it. The scite of this dam is unfavorable in several points of view. First, in regard to the facility for securing its permanency, in the absence of rock foundation, which cannot be done without increasing the length of the weir, and of course the expense of construction. Second, the great length of guard bank necessary to prevent the water from overflowing a considerable area of valuable land, and thus rendering the payment of heavy damages inevitable ; and third, the peculiar porosity of the soil, through which the water percolates, rendering the adjacent lands unproduc¬ tive, and subjecting the State to the payment of damages, which have not yet been liquidated. The committee were assured, that little more than a mile higher up the creek, an eligible situation for a dam could be obtained, where a good foundation would be had, and the height of the dam materially diminished, and where very little damage would be occasioned to private property. Not having viewed this scite, the committee forbear speaking confidently on the subject, but recommend that discretionary power be given to the Canal Com¬ missioners, to change the location of this dam, if in their opinion, after due examination by a scientific engineer, the interests of the Commonwealth would be promoted by such change. An engineer employed by the committee estimated the cost of re¬ building this dam on the old scite at nineteen thousand one hundred and forty-three dollars. The engineer employed by the Canal Com¬ missioners estimates it at twenty-one thousand nine hundred and twenty dollars. This difference in a work of that character and magnitude, is not material, and in round numbers, twenty thousand dollars might be considered a fair estimate. The cost of constructing a dam about a mile higher up the creek, at or near M’Guffin’s Falls, and extending the feeder to that point, is estimated at twenty-nine thousand dollars, and would avoid the necessity of keeping up a guard bank of about three fourths of a mile in length, of which a part has already been swept away, and being composed of light allu¬ vial material, will always be subject to injury from freshets. The aqueduct over French creek, needs considerable repairs. One of the abutments mu3t be rebuilt; and the upper end of one pier has given way. The timber of the superstructure is decayed, and must be re¬ newed. Large deposites of sand and gravel have been made at dif¬ ferent points of the canal, by the discharge of streams and freshets from the hill sides. 11 The berm bank has in many places been protected by a timber wall at the foot of deep side cuts. Much of this will require repairing, and in some places renewing—some of the bridges ought to be re¬ paired. The object and design of this feeder, being to supply the Conneaut and Shenango lines of the Pennsylvania canal, usually denominated the Erie extension, with water, at the summit level, by conveying the waters of the French creek into Conneaut lake, making use of said lake as a reservoir. The feeder then, is entirely useless, until one or both those lines are made navigable. Should the Shenango line be completed, the waters of Conneaut lake alone might be suf¬ ficient to supply that, for the limited trade that will be thrown upon it previous to the connection with the lake been completed. If these premises are correct, as your committee believe them to be, the French creek feeder, as such, will not be needed until the canal from Conneaut lake to Erie is finished, which in all probability will not be before the spring of 1842. To put the feeder in complete navigable order during the present season, will only be to expose it to the fury of floods and storms, and the more slow, though not less certain operation of all-destroying time and natural decay, for two years before it is actually wanted. Your committee, therefore, are of the opinion that any expenditure upon the French creek feeder at this time, except for repairing a few of the bridges, and providing materials for the dam which ought to be put under contract during thq present season, would be injudi¬ cious, if not altogether useless. For this purpose the sum of fifteen thousand dollars would be sufficient. FRANKLIN LINE. One of the dams upon this line has been entirely swept away. A canal was substituted for the dam and slackwater, which is about one third completed. Another dam has been partially destroyed, thus rendering the navigation entirely useless, except for descending, when the water is high. The principle amount necessary to put this line in navigable order, will be required for repairing the dams. The towing-path in some places stands in need of repairing, and in some places has been repaired. The construed >n of this line seems to have been very unwise, and a further expenditure of money in repairing it, would also seem to be 12 injudicious. If the waters of the French creek should be found ne¬ cessary to supply the Shenango and Conneaut lines, the capacity of the feeder will be adequate to convey nearly all the waters of that stream, except during the periods of freshets or wet seasons, into Conneaut lake, as the reservoir for supplying the above mentioned canals. Having thus diverted the stream from its natural channel, would it not be folly to maintain dams and locks, collectors, supervi¬ sors and lock keepers upon a stream, that for three-fourths of the boating season, will be destitute of an adequate supply of water? Your committee believe it would be advantageous to the inhabi¬ tants along the French Creek valley, to have the dams removed, leav¬ ing to them the unobstructed natural descending navigation of the stream. Yet the committee are unwilling to recommend such an apparently destructive measure, until the completion of the Erie extension be consummated, when actual demonstration will prove the correctness or fallacy of their anticipations. WEST BRANCH. The West Branch canal is in fine navigable order, seeming to re¬ quire very little repairs, except what may be necessary for giavelling and cribbing the dams, and repairing and rebuilding a few bridges. With regard to the amount actually necessary for properly, and as near as may be, permanently, securing the dam, the committee had not, as has been already stated, the means of acquiring accurate infor¬ mation, but when they take into consideration the time, the season and circumstances under which the report and estimate was made by the engineers, they are disposed to suspect that those estimates are pre¬ dicated upon information obtained from irresponsible, or probably interested persons, rather than founded upon actual, careful, personal examination. And when they observe, as they have frequently had occasion to do, the strong disposition manifested throughout those reports, to avoid erring on the side of economy and frugality, the committee feel constrained to believe, that the amount required for repairing the dams on the West Branch, are greater than a judicious application of the repair fund would justify. These remarks may be deemed invidious, perhaps taken as unkind, but they result from the honest convictions of the committee, after a deliberate investiga¬ tion of the whole subject. Your committee entertain the opinion 13 that the sum of forty thousand dollars will be amply sufficient for repairs on this division, during the ensuing year. NORTH BRANCH. This division of the public improvements is far from being in good condition, but is navigable at present, and perhaps with proper c-are may be kept, during the season, in a condition to accommodate all the business that may be offered. The feeder dam at Lacka¬ wanna has been destroyed by a freshet since the adjournment of the Legislature. A temporary dam has been constructed, which now turns the water into the canal, but that cannot be expected to last long. The dam should be rebuilt with the least possible delay. The scite of the old dam is a very bad one, being a gravel bottom, a por¬ tion of which has been washed out to the depth of twelve or fifteen feet, and requiring a guard bank on the north side of considerable extent. The committee were informed by several respectable gen¬ tlemen who are acquainted with the locality, that there is a situation about a mile and a half up the river, from the present dam, where a rock foundation could be obtained, with rocks on each side of the river, where a permanent dam might be erected at a small expense. Such a change would, however, of necessity encounter the expense of extending the feeder; what that would amount to, the committee had no opportunity of ascertaining; but would suggest, as in the case of the French Creek feeder dam, the propriety and probable utility of authorizing the Canal Commissioners to investigate the subject, and exercise their discretion, as in their opinion the interests of the Com¬ monwealth might require. A portion of the vertical wall, on the towing-path side, at and below Pittston, and a part of the berm bank wall, above Pittston, has fallen down, and several hill slips have oc¬ curred, leaving considerable obstruction in the canal. For a more detailed account of the repairs necessary upon this line, the com¬ mittee submit the following statement, made by Dr. Whippo, who 1 was employed by and accompanied the committee. North Branch Division, below Nanticoke Dam. In order to put this division in complete repair, it will be neces¬ sary to raise the wall between the guard lock and the upper end of the pier head, adjoining the dam, to rebuild the guard lock, make a 14 new one at Henlock’s creek, rebuild the seven lift locks, repair fifty- five road and farm bridges, and repair the Nanticoke dam. The most economical plan to do this, it appears to me, would be to build the crib above the guard lock, repair the bridges and Nanti¬ coke dam, make the ordinary repairs, and furnish the materials for the locks during the present season; and next season draw off the water and build the locks, using the old foundations and irons, which I have no doubt would answer, with some slight alterations and re¬ pairs. This would be more economical than to build the new locks beside the old ones with the water in the canal, because we should not only save a heavy expense in the two items just referred to, but we should also save the unavoidable expense of pumping and bailing water in the seven lift locks. The locks should be built on the combined plan. The guard lock at Henlock’s creek is necessary, as the water of this stream frequently rises very high, which, with the present guard gates, often stops the navigation for several days at a time. I would locate this lock below the creek, and let the water in flood times discharge itself over the wier now constructed. The banks of the canal, and the adjoining banks next the river, between the guard lock and this stream, are in several places washed away. This was done several years ago by a high flood, which destroyed the embankment adjoin¬ ing the guard lock, and let the water into the canal below, making so heavy a pressure upon the banks as unavoidably to break them. By making the new guard lock where I propose, it will not be necessary to repair these banks. If the water of the river should ever rise high enough to flow over the banks, (which must be a rare occurrence,) and cover the towing-path, it cannot at any rate remain up long, and would not therefore be a very serious inconvenience. A. heavy expense would in this way be saved in raising and repairing these banks; the floods of Henlock’s creek could never do any injury, as they would all be discharged over the wier, and the navigation could not be impeded, except in very extraordinary floods, and then only for a very short time. The following estimate of the cost of the locks, I feel confident, is sufficiently high to cover the cost, making them upon the combined plan, and in the most substantial manner. In examining the estimate of the cost of the locks upon the Wyoming line, above Nanticoke dam, which are made upon the combined plan, I find that none of 15 Shem cost more than five thousand dollars, except one, (the third) which cost $5,389. The others cost a little more than four thou¬ sand dollars, except two, which cost $3,585 each. The locks on the West Branch cost nearly four thousand dollars each on an ave¬ rage, those on the Delaware division, four thousand seven hundred dollars each, and those on the Juniata division, (Frankstown line,) three thousand one hundred dollars each. It is true that similar work will cost more now, on account of the increased price of labor and provisions; but then, by using the old foundations and irons, nearly as much may be saved as will balance this disadvantage. Another reason which induces me to believe that the estimate is high enough is, that several individuals entitled to credit on this line, informed me that the stone could be delivered at the scites of the locks at one dollar a perch; and as a confirmation of this statement, Mr. Crownover, one of the supervisors, told me that he had entered into contract with responsible individuals, to build several bridge abut¬ ments of stone , at two dollars a perch, including the excavation of the foundations. The bridges, in my opinion, ought to be built upon a cheaper plan than to make stone abutments. As I said above, they are fifty-five in number, twenty-four of which require simply to be keyed up, and they will last several years. The remaining thirty-one stand on wooden tressels, which are so much decayed and broken as to render them unsafe—the superstructures are in some instances decayed at the ends also. These bridges can be cheaply repaired by sloping down the embankments at the ends of the bridges, and putting in two additional reaches and two new tressels at each bridge. The tressel on the berm side could be set a little further in towards the canal than the old ones, and the superstructure keyed up, and the decayed ends cut off. In this way, they may be made useful and good for many years. In regard to an additional feeder for this line of canal, I can only say, that none can be taken in of any value, so far as I know, ex¬ cept by making a high dam across the river at the head of Rocky Island, which would be exceedingly expensive and injurious to the river navigation. Fishing creek, which has been talked of as a feeder, becomes so low in dry seasons, that it would hardly be worth while to incur the expense of taking it in. Besides, I am of opinion that the line can be sufficiently supplied from Nanticoke dam. In 16 making- the guard lock at this place, a sluice should be constructed,, sufficiently large to let through the requisite quantity of water; and as there is a descent on the bottom of the canal, of one-tenth of afoot in a mile, and as the banks of the canal are thick and apparently strong, I have no doubt that a sufficient supply could be sent down, without doing any injury to the canal or the navigation; it is true it would cause a considerable current in the canal; but when it is con¬ sidered that much the largest portion of the freight—perhaps nine- tenths of it—will be downwards, and that the return boats will generally be empty, this objection will have but little force.
