MIGILL & WITHEROW, PRINTERS AND STEREOTYPERS. 1 873. REPORT OF THE SUPERINTENDENT. To the President and Board of Directors of the Sutro Tunnel Company. GENTLEMEN: I have the honor to submit herewith reports fromnt the heads of our different departments, containing detailed statements of the operations and expenditures in prosecuting the work on the Sutro tunnel, for the year ending November 30, 1872. From the statement submitted by the accountant at the works, Thomas James Tiddy, Esq., it will be perceived that the expenditures for the year have been $937,589 46;. Those for each month have been classified into tables, by the able secretary of the company, Pelham W. Ames, Esq., in charge of the general office of the company at San Francisco. During the year a supply department was organized, a storehouse erected, and a general system of book-keeping and vouchers introduced, by which it became possible to check and control all articles received at the different points on the line, while a great saving to the company was thereby seculred; for instead of' buying supplies in small quantities, from small dealers in the neighborhood, purchases were mostly made in suitable quantities, either from the manufacturers in the East or from importing houses at San Francisco. The system of book-keeping introduced by John G. Lyon, Esq., who has been in charge of this department, is quite creditable. By referring to the stock ledger, into which are )osted the values of all the articles on hand, received, and disbursed, it is an easy matter to tell, almost at a glance, the value of each article received and what has become of it. The annexed tables illustrate the system, being copies of the ledger account for the months of September, October, and November. Upon examination, it will be found that on November I the stock on hand was............. $73,825 28 Received during the month........................ 48,534 34 Making a total of................................... 122,359 62 There was disbursed during November.......... 37,282 11 Leaving on hand a value, Nov. 30, of............ $85,077 51 In order to show how many different articles are required in the construction of our work, it will probably prove interesting to examine the list of articles received at and distributed from the storehouse during the month of September; few persons would suppose that such a variety of nmerchandise would be required in the construction of a tunnel. There will also be found a table showing the character and quantity of freight, together with the prices paid for transportation, as recorded at the company's office at Virginia City. The principal articles distributed from this point are firewood, coal, and lumber, which are received by the Virginia and Truckee railroad, and which, on account of' their bulk, do not first go to the storehouse, but are delivered directly at the shafts. This office has been in charge of Captain C. W. Smith, who has attended to all the freight business of the company in a diligent manner. It was found advisable to bring all the carpenters' work under a separate department, with a distinct head, to which position Mr. G. A. Taylor was appointed as master carpenter for the company. Under his supervision all the buildings and hoisting frames on the shafts were erected, also some of the buildings at the mouth of the tunnel; and at the present time the timbering of the tunnel and shafts are carried on under his direction. In Mr. Taylor's report will be found a complete list of all the buildings erected and owned by the company. The report of Mr. D. J. Bousfield, paymaster and real estate agent, embraces an account of the town of Sutro and the sales of lots which have been thus far consummated; it was laid down as a rule that a payment of one third should be required upon the purchase of any lot, the remaining two thirds to be paid in equal installments in six and twelve months, with interest at the rate of one per cent. per month. Several of the lots have been paid for in full at the time of purchase. A condition has been inserted in all of the deeds, requiring the owners to plant a shade tree for every 121 feet of street frontage, a provision which will no doubt be strictly carried out, and which is a most desirable one in a country where vegetation is but limited. A fund has been created, by the contribution of each person employed by the company of one dollar per month, for the purpose of establishing a hospital and employing a resident physician, whose duty it is to attend to all subscribers who shall require his services. It may be expected that when the number of persons employed by the company shall be increased, which it is hoped may be the case next summer, the fund will soon reach a sufficient sum to build a hospital. In mining works more or less accidents occur, though our company has been remarkably fortunate thus far. Dr. McPherson, a gentleman well qualified, who has been employed as resident physician', has also rendered a report. Mr. H. P. De Noon, who took charge of our mining department early in December last, has entered upon his duties with commendable energy. It will be seen from his report that on the 21st of December the header had reached a length of.......... 3,451 feet. The enlargement was completed.................... 1,100 " And the shafts gave the following measurements: No. 1. No. 2. No. 3. No. 4. Depth attained.... 454 feet. 623 feet. 377 feet. 421 feet. Depth still to go. 69 " 418 " 984 " 1,064 "' Total depth..... 523' 1,041 " 1,361 " 1,485 " It is expected that No. 1 will reach the proper depth, and the drifts will be ready to be commenced by February 1st next; that will give us three points of attack where but one existed before; No. 2 will probably be down within six months, which will add still two more faces for the tunnel to be driven from, or, in other words, we will be enabled to make five times the progress we have heretofore made. It will require a year probably before either No. 3 or No. 4 can reach the tunnel level. The work will be prosecuted without any firther delay, since all the necessary provisions have been made to push these shafts down to completion. A report in great detail will be found from Mr. John Anderson, our able chief mechanical engineer, who has most carefully noted down all that has transpired in this department at the different points along the line of the work. He also gives a complete list of all the machinery on hand at each point, and also a list of the men employed, together with their compensation. Mr. H. Schussler, who has lately been appointed civil engineer-in-chief of the work, has made no written report, but has furnished us with some interesting maps, which are attached hereto. From these maps it will be seen what system of triangulations has been carried out, and what measurements have been deduced therefrom. It will be perceived that shaft No. I is located from the mouth of the tunnel a distance of................. 4,915 feet. Shaft No. 2........................... 9,065 " Shaft No. 3........................................ 13,545 " Shaft No. 4............................... 17,69 " Point of intersectidn with Comstock lode..... 20,145 The distance between the different points being as follows: From mouth to Shaft No. 1..................... 4,915 feet. From shaft No. I to shaft No. 2................ 4,150 " From shaft No. 2 to shaft No. 3.............. 4,480 " From shaft No. 3 to shaft No. 4................ 4,150" From shaft No. 4 to Comstock lode............ 2,450 " Or a total of.............................. 20,145 feet. The depths of the shafts have already been given above. The triangulations were executed with a transit instrument made originally for the city of San Francisco; an instrument which cannot be surpassed for accuracy an(l solidity of construction. Repeated trials showed the same results with such precision, that no doubts can be entertained about the reliability of the figures furnished by Mr. Schussler, under whose able guidance the difficult surveys in the construction of the tunnel, I feel assured, will be carried out to a successful end. The progress made during the year in sinking the different shafts may appear small and less than was expected. It must be considered, however, that the machinery employed during the greater portion of the year was intended only to reach down but a limited depth, and has done remarkably well in battling against the great enemy of' mining, viz, the influx of water. For several months no work at all was performed on the shafts, while waiting for the new machinery and the buildings to be completed, and after the old engines and pumps utterly failed to master the water any longer. All the machinery has been selected less for beauty of finish than for strength and capacity to perform its work, and it may safely be relied upon as entirely adequate for almost any emergency. The steam engines used for hoisting have a sufficient capacity to hoist from the bottom of the shafts all the rock which can possibly be excavated by the use of drilling machinery, even should it be decided to excavate the drifts therefrom to the full size of the tunnel. As regards the pumps which have been adopted, they were selected upon the basis of being able to pump an amount of water equal to the greatest quantity pumped out of any one mine on the Comstock lode; that is, 20,000 gallons per hour while running at a very moderate speed, which in case of emergency could be increased 50 per cent., thus giving a capacity of 30,000 gallons per hour, or 720,000 per day; which will not likely ever be required. We might possibly have succeeded with smaller pumps, but considering the great delay and loss to the company had they proved inadequate, the extra cost will probably prove a judicious outlay in the end. The pumps selected are the double-acting cataract steam pumps manufactured by Messrs. Allison & Bannan, of Pottsville, Pennsylvania, with steam cylinders 20" by 72", and 10" discharge pipes, weighing 20,000 lbs. each, and capable of lifting the water from station to station 300 feet apart. Of these pumps we have thus far received nine, and shall, before the shafts will be completed, require seven more, making sixteen in all, distributed as follows: Shaft No. 1, two pumps. Shaft No. 2, four pumps. Shaft No. 3, five pumps. Shaft No. 4, five pumps. Besides these, we have also on hand four large sinking pumps, one at each shaft, weighing five tons each, ready to be put in use at any time should the influx at the bottom at any time become too great for the small sinking pumps now in use. Steamp pumps of this capacity had not been introduced before on the Pacific coast, though they have been in use quite extensively for some years in the coal regions of Pennsylvania. They prove greatly preferable to the old style Cornish pump now in general use, as to simplicity, cheapness, durability, and diminished liability to get out of order. The five pumps now in operation at our shafts give the very best satisfaction. With our present machinery-all in first-class working order —we are now prepared to fairly start out on the gigantic task of bringing our shafts down to the tunnel level, at depths of from 500 to 1,500 feet, and we may confidently look to their early completion without any further vexatious delays. The requirements of the shafts and affairs generally at our works will be much more promptly attended to hereafter when the telegraph line, connecting very ingenious a, b, c printing telegraph instruments, which will be stationed at each point, shall have been completed. They were or dered almost a year ago, but had not been furnished on account of some imperfection in the instruments, which hlas at last been remedied; and it is expected that they are now of such perfection, that they may be operated by any one who can spell, and kept in working order without much difficulty. The line will probably be in operation inside of sixty days, everything appertaining thereto having just b)een forwarded overland from New York. The diamond drilling machinery lately procured, which it had been impossible to bring into use in the shafts before proper pumps were provided, will also shortly be started with steam, and good results are anticipated. They are well adapted to the drilling of holes several hundred feet in depth, of which from 8 to 12 will be drilled in each shaft at proper distances, the machines removed, the holes filled with sand, and the rock then blasted out in sections of from 3 to 6 feet, by means of galvanic batteries. Some shafts are being successfully sunk under this system. near Pottsville, Pennsylvania, under the supervision of General Henry Pleasants, the able engineer in charge of the extensive works of the Philadelphia and Reading Railroad Company. I entertain no doubt that, after these drills are fairly in operation-and they will be during this month at shafts Nos. 3 and 4-our progress will average at least three feet for every twenty-four hours, including all ordinary delays which may occur. The diamond drills will also be brought into operation in the header of the tunnrel shortly, and afterwards be employed in the enlargement. These will be propelled by water-power, secured by conveying, by its natural flow, the water pumped from shaft No. 3, and probably also that pumped from No. 4, (which latter, however, will have to be pumped an additional height of about 150 feet,) to the divide between shafts Nos. I and 2, which has an elevation above the tunnel level of 1,350 feet, from whence it will be conveyed in pipes to the face of the tunnel, to propel the diamond drills by means of hurdy-gurdy wheels; the pres sure thus obtained will be 675 pounds to the square inch, and a sufficient power may thus be secured to drive the number of diamond drills which it may be desirable to place in the face. The quantity of water will be largely increase(l by the construction of dams and reservoirs in the ravines adjacent to the flume which conveys the water from shaft No. 3 to the divide, and in which will be stored up the rain water accumulating during the winter months and that from melting snows, which falls to considerable depths in some of the deep gorges, and does not altogether disappear until the month of June. The nature of such directly-applied water-power during the construction of' the tunnel cannot be over-estimated, when we consider the expense of fiel and the great loss of power sustained in compressing air-the only other available motive power-since the employment of steam would be quite impracticable in the header. After the connections from the shafts are made, the supply of water furnished by the pumps will of course fail, while that obtained from the reservoirs will be of a permanent character. To this will, at a future day, be added the water flowing from some remarkable springs, situated at an elevation of about 1,000 feet above the tunnel level, at a distance of about five miles to the northward, the title to which has lately been procured, and which are estimated to supply from nine to twelve miners' inches, equal to from 150,000 to 250,000 gallons for every twenty-four hours. We have already constructed a darn near shaft No. 1, forming a large reservoir, into which the water pumped from this shaft flows, and into which the water from the divide will also be allowed to flow for the present, until the water-works froom the greater elevation shall be completed; from this reservoir pipes have been placed in position to the air shaft, down which they pass to the tunnel and to its face, a distance altogether of' about a mile, with a fall of 500 feet, and the work is so far completed that the diamond drills may be started by means of the power furnished thereby almost any day, certainly during this month. The daily average progress, both at the Mount Cenis and Hoosac tunnel, reached as much as ten feet, with the aid of percussion drills. We may expect at least a similar progress with the diamond drill, taking into consideration that our rock in all probability will prove by far more favorable to work. The whole problem of the time required to complete the Sutro tunnel is now reduced to this question: How long will it take to sink shaft No. 4 an additional depth of 1,064 feet, and drift therefrom a distance of' 2,450 feet to the Comstock lode? Without giving any specific figures, it may readily be deduced friom those already given, that the time required to complete the work, provided it is pushed along with ordinary vigor, cannot much exceed thirty months from the 1st of January, 1873. The great difficulties have already been overcome.. The complicated surveys, the construction of roads, the selection and erection of ponderous machinery, the construction of buildings, the organization and systematizing of the work, the employment of competent heads for each department, the selection of. capable and faithful mechanics and workmen-all have been accomplished; and what remains to be done is but a question of so much time and a given amount of money. During the past year it was deemed desirable to secure the title to an additional quantity of land near the mouth of the funnel, and in consequence purchases were made from the United States, the State of Nevada, the Central Pacific Railroad Company, and private individuals, including two ranches on both sides of the river, embracing 1,200 acres of excellent grazing land, which swell the whole area now owned by the company to 4,920 acres. The purchase of these ranches was especially desirable, since with them was conveyed the water-power, for nearly three miles, existing on the river, having a fall of 45 feet, to which has been added by location further down an additional fall of'50 feet, giving a fall, embracing all the water contained in Carson river, altogether of 95 feet, which at some future day will prove of great value in the erection of reduction works. Thiese ranches are well fenced, have many improvements on them, including a number of houses, stables, corrals, ice-houses, etc., etc. One of themn produced last year over 200 tons of hay, which was included in the purchase. Considering their close proximity to the tunnel entrance, and the fact that probably one hundred head of horses and mules will have to be employed during the time of constructing the tunnel, it will prove highly profitable to own this grazing land, upon which the animals can be turned out at any time and find ample food at no expense to the company. A most interesting and valuable discovery has been made upon this land adjacent to the river. It has been found that vast quantities of tailings have accumulated thereupon, which may amount to 50,000 tons, and possibly three or four times that quantity, swept there by the floods from the river and cation mills above, which prove by numerous assays made at our office to contain from $5 to $20 per ton of gold and silver, the latter largely predominating. That these tailings will be reduced and made to pay handsomely at a future time, when concentrating and reduction works shall be erected, admits of no doubt. During last summer we purchased three thousand cords of wood, at $8.15 per cord, stacked up on the bank opposite the tunnel entrance, which has been partly hauled by teams to the machine shop and shaft No. 1. It is contemplated to extend the railroad track from the tunnel to the river, the iron for which is now on the way round Cape Horn, enabling us to deliver the wood at an expense of 50 cents per cord, which is now done at a cost of from $2 to $3. This wood is floated down from the Sierra Nevada mountains, near the headwaters of Carson river, where an almost inexhaustible supply exists. We shall probably procure large quantities thereof the coming summer; also timbers for use in the tunnel, which can be furnished in this manner at greatly reduced cost. 13 At shafts Nos. 2, 3, and 4 considerable quantities of coal have been delivered, procured from the coal mines at Evanston, Wyoming Territory, situated on the western slope of the Rocky Mountains, a distance from our place of nearly 600 miles. This coal costs, delivered at the shafts, from $20 to $21 per ton of 2240 lbs., the freight on which forms the principal item of expense, the Virginia and Truckee Railroad Company alone charging $6 per ton for conveying the same 50 miles over their road. In this connection I would most urgently advise cooperation by our company in the construction of a railroad to Wadsworth, on the Central Pacific railroad, a distance of 35 miles, over an almost level country, which will insure us a saving on the cost of coal alone of from $4 to $5 per ton, and which would prove a most profitable investment. This road can be graded and provided with a single track, switches, etc., at a cost of about half a million of dollars; but little rolling stock being required besides that which the Central Pacific Railroad Company would be willing to fuirnish. We have already located on the line of this road some very extensive iron and lime deposits, also material for the manufacture of fire-brick, which may prove of considerable value. The lime will be utilized for laying brick, (which may be manufactured at almost any point, of most excellent quality, two kilns of 300,000 having been burned already last fall,) in building up the town of Sutro, near the mouth of the tunnel, which has been surveyed, and for which a brilliant future may be predicted. The town was only laid out some time last fall, and already a number of lots 25 x 130 feet have been sold, varying in prices from one hundred to fifteen hundred dollars, according to location, and quite a number of buildings have been erected. After the completion of the tunnel, all or nearly all the ore extracted from the Comstock lode will find its way to the mouth of the tunnel, since the extraction and transportation can be effected over the road in the tunnel at one-tenth its 14 present cost. This advantage, taken together with the favorable topographical formation at this point for the erection of reduction and self-acting concentrating works, of which the water running from the tunnel will form the essential requirement, makes it not a matter of speculation, but one of certainty, that the bulk of the Comstock ores will be delivered and reduced at this point, bringing with it a numerous population of mill-hands, teamsters, and other emiployes connected with the reduction works. The introduction of comfbrtable passenger cars will also induce many of the miners to choose this point as their place of abode, and we may therefore look upon the large increase in population of the town of Sutro after the completion of the tunnel as a foregone conclusion. It is a well-known trait of our western people to take time by the forelock, and, the completion of the tunnel once assured, people will not wait for settlement until that time arrives, but we may calculate upon an immediate, constant, and steady growth of the town. Besides the results which will probably be attained, already enumerated, there are others which will add largely in making, this a most important point for a town. It is contemplated to bridge the river at a point opposite the tunnel, from where an old wagon road, which cuits off twenty-five miles, leads to the fertile Mason valley and that of Walker river, which are already thickly settled with farmers, the former containing the only flour mill in the State of Nevada. This road will also connect with the flourishing mining district of Colunmbus, where large deposits of borax exist, and Sutro will be the nearest settlement and trading point to these localities, and will form the natural outlet for that section of country. The construction of the bridge and a few thousand dollars spent upon the road referred to would at once bring this trade to our town, largely increasing the- value of our property, and thus materially contributing to the needed funds required to complete our extensive work. A large revenue will also be derived from the sale of water running from the tunnel to supply the town. A stone reservoir has already been constructed, over two hundred feet above tle'level of the tunnel, which is supplied by natural springs, from which a system of pipes has been extended through a number of the streets and connecting with the buildings of the company, where hydrants and hose have been placed, from which a stream 135 feet in height can be thrown by simply opening a valve, thereby supplying the most ample protection against fire. With these magnificent prospects before us, it would be a pity indeed to see our great work come to a stand-still for -the want of funds: and still this fate seems quite possible, for the money thus far obtained was only secured under the presumption that the Congress of the United States, under whose special authority the work was commenced, would render such aid in the shape of a loan —not so much on account of the limited amount of money thus furnished-but in order to recognize its national importance, and thus place it before the capitalists of this country and Europe as one affording the most unquestionable security as to the rights attached thereto and as a safe investment. This presumption was justified by the appointment of a commission by the President of the United States, whose report was submitted to Congress at its last session, recommending the work to favorable consideration, and the unanimous action of the Committee on Mines and Mining of the House of Representatives after the most searching and exhaustive examination in advising the loan. A bill now pending before Congress, which will be reached in the House of Representatives at an early day, provides for a loan not to exceed two. millions of dollars, and gives to the Government a first mortgage on all the valuable property of the company, which will increase many fold when the means are once absolutely secured to bring the work to completion beyond any peradventure. That the passage of' the bill referred to will secure that desirable result cannot be doubted; for what financial men already connected with the work now want is this additional recognition, to induce them to advance all the money which may be still required to push the tunnel to final completion. As a financial proposition simply, the mortgaging of all the vast property of the company to the United States, fobr the sake of' securing a loan of two millions of dollars, would be very undesirable, were it not for the increased feeling of security already alluded to, which will procure the funds still required. I must therefore express the sincere hope that Congress will consent to render the limited aid asked for, which is given under such security that the amount loaned will be repaid, beyond any doubt whatever, at an early date, and thus contribute to the final completion of the most gigantic undertaking now in progress on this continent, which will practically prove the contin uance of mineral lodes to greater depths than have ever been reached before in the world, and will thus give a great value to the large extent of mineral lands possessed by this country, and place untold millions in the coffers of the nation.

JAS. TIDDY, Acct. S. T. Co. REPORT OF THE CHIEF OF THE SUPPLY DEPARTMENT. OFFICE SUPPLY DEPARTMENT, SUTRO, LYON COUNTY, NEVADA, Deceimber 23, 1872. ADOLPH SUTRO, Esq., General Superintendent. DEAR SIR: I have the honor to submit the following report of the business of the Supply Department of the Sutro Tunnel Company during the months of September, October, and November, 1872. I assumed charge of this department on the first day of September ultimo, 2 18 prior to which time no organization of such a department had been made, and immediately addressed myself to the task of systematizing the mode of receiving, distributing, and accounting for supplies ordered for and used upon this work. As the line of operations extends over a distance of six miles, and supplies are received at from ten to fifteen different points, many articles never being received into the warehouse at the mouth of the tunnel, but being delivered at the points of work direct from the railroad depots or from places where purchased-at Virginia City, Dayton, and elsewhere-it was at once apparent that whoever received supplies shouldl be required to report daily to the office of this department all articles received, with their condition on arrival. In this way only could the daily receipts of the company be known and properly classified upon our books. I therefore prepared a blank form of material report (Exhibit "A") which each person receiving supplies is required to fill up daily and forward on the following morning to the storehouse office. By these reports the bills of parties furnishing material are checked, and they also serve as a basis for the charges of supplies against the different points of the work. To regulate the transfer and shipment of articles from the storehouse to points upon the line of work and to and front'the different shafto, I prepared blank forms of shipping receipts, (Exlibits " B" and "C,") the former for lumber and the latter for general stores, which are required to be filled up by the shipper, receipted by the consignee, and by the latter party forwarded to the storehouse office. These receipts, corresponding with the reports sent in daily, have been found an effectual check for transfers and receipts upon the work. To regulate the issuance of supplies from the warehouse at this point, as well as purchases from outside parties, blank forms of requisition (Exhibit "D") were prepared. These are classified into three divisions-the mining, carpenter, and engineer departments. Each requisition, being approved by the superintendent of the department for which supplies are required, is forwarded to the General Superintendent's office, from whence, on final review, it' approved by him, it is sent to the storehouse office. Upon these requisitions, thus approved, all the material used upon the entire work is issued or purchased. The advantage of this system of requisition is, tlat it affords the General Superintendent an opportunity of knowing what supplies are required and being used, without the necessity of personal and daily visits at each point of work, which his absence or duties oftentimes renders impossible. Warelehouse.-During the month of October a large and commodious warehouse was erected at the mouth of the tunnel, one end of which has been partitioned off for an office, and above which are sleeping-rooms for clerks employed in this department. The warehouse is now filled with a large stock of all staples used upon the work, (excepting powder, coal, wood, and lumber,) the larger portion of which has been purchased either directly from the manufacturers or at wholesale in San Francisco or the East. The value of stock on hand December ist was $85,077.51. A large area has been graded, at considerable expense, for some distance 19 in the rear of the storehouse building, for storage of lumber, and several small buildings moved thereon for storing pipe, grain, etc. Powder-house.-A powder-house was erected in October about one-eighth of a mile distant from the storehouse building, in which all black and giant powder, fuse, caps, etc., etc., are stored. Lumber.-All lumber used by the company has been received from the Sierras, either from the country west of Carson City, and distant some thirty (30) miles, or from Truckee, a point of the Central Pacific railroad, some ninety (90) miles distant. Nearly all of it is pine, and it has been delivered to us at the railroad depots at Virginia City and Mound House at the following prices, viz: Rouzyh Lumber.-Twenty-four dollars (.$24) at Mound House; and twentyseven ($27) at Virginia City, per thousand feet. Clear Rough.-Sixty-five dollars ($65) per thousand feet. Clear Dressed.-Seventy dollars ($70) per thousand feet. The price of shingles has ranged, according to the market, from five -0 dollars ($,5.50) to seven ob-1- dollars ($7.50) per thousand; the larger portion used being purchased at the former rate. Freight.-The discrimination made by the Central Pacific railroad against Nevada has necessitated the shipment of all freight received from the East through the State and to Sacramento, California, and thence backward, one hundred and sixty miles, to Reno, the point where the Virginia and Truckee railroad connects with the overland line. This has sometimes caused great inconvenience and always unnecessary delay. The average cost of freight per car-load from the East has been $850; special rates being made wherever possible. Coal.-We purchase Cumberland coal for blacksmithing in San Francisco, our last receipt being invoiced at $32 per ton of 2,000 lbs. The freight from San Francisco to Virginia is $29.60 per ton, making total cost per ton $61. We received during October and November fifty-four (54) cars, of ten (10) tons each, of Rocky Mountain coal. Its cost is seventeen dollars ($17) per ton delivered in Virginia City; six dollars ($6) per ton of which amount is paid for freight from Reno to Virginia, a distance of fifty-two (52) miles. Even at this enormous price it is found to be cheaper than wood, and with reduced freights must soon supersede the latter as fuel in this region. Wood. —The average cost of wood delivered at the three shafts nearest Virginia City (Nos. 2, 3, and 4) is about $14.50 per cord, and at the mouth of the tunnel and shaft No. 1 $10.50 to $11 per cord. All, or nearly all, of our wood is obtained from the Sierra Nevada mountains, and is either floated down the Carson river from Alpine county, California, or flumed down the mountains to Carson City, and thence transported by railroad or team to Virginia City. Nearly all wood in this country is pine; some fir is found, and small quantities of nut pine, a quality better than either, are obtained from the foot-hills east of the Carson river. Our main supply, however, is and must be obtained from the Sierra range. We have now some eighteen hundred cords on hand at the storehouse, besides from six to seven hundred cords at the several shafts. 20 Charcoal.-Until the past month our supply of charcoal has been procured from the foot-hills east of this place, but in October we purchased 10,000 bushels at Truckee. It is, however, greatly inferior to that. heretofore used, being burned from soft pine, while that formerly obtained is made from the nut pine. Nut-pine coal costs,'delivered at the shafts, 30 cents per bushel. The other will cost nearly if not quite as much, as it costs about 24 cents per bushel delivered in Virginia City. Accounts. -The books of this office are1st. A Stock Ledger, showing quantities only, on which are entered daily the amounts received and distributed on the entire line. 2d. Invoice Book, in which are entered all bills of goods purchased by the company, and the receipt of the articles checked thereon. 3d. Receipt Journal, taken from Invoice Book, and arranged for posting to Ledger. 4th. Shipping Book, on which are entered all deliveries to points on the line, both from the warehouse and from outside parties, by bill. 5th. Delivery Journal, on which are classified the general deliveries on the line of work for posting to6th. General Ledger, which shows whole business of this department. The minor or auxiliary books are lumber, coal, wood, and freight, a special account being kept for above-named articles. Auditing Office.-As this department includes not only the duties of receiving and distributing supplies, but also those of an auditing office, accounts are also kept with each firm furnishing supplies, and their bills certified to' the company's accountant for payment. The certificate'embraces not only the receipt of the material invoiced, but the correctness of calculations, fairness of prices, etc., etc. It will readily be perceived, from the quantity and character of supplies received during the past three months, that the duties of this branch of the department are very onerous and involve grave responsibility. Three clerks are employed in this department, and one laborer in the warehouse building. There is also a large and well-appointed office building at Virginia City belonging to this department, which is in charge of Captain C. W. Smith, freight and purchasing agent at that point. His report will be found of value, and is herewith transmitted. The teams belonging to this department occupy, with those belonging to the general office, three convenient and well-built stables, and we run a daily express, for transportation of light material, to and from Virginia City. This express also carries the mail to and from the village of Sutro. Owing to the difficulties attending the introduction of the system heretofore described, the absence of a warehouse and office facilities at a time when our business was most pressing, (September and October,) and the difficulty of procuring accountants familiar with the business, which, it will be perceived, is varied in character, the articles received and distributed being almost endless in variety, I have been unable to give as detailed a statement of the work performed by this department, or to classify receipts and distributions as closely, as if it had been organized for a longer period. Indeed, only until 21. the present month have the clerks of this office had any time to devote to reports or classifications, their entire time being occupied in receiving and attending to the distribution of supplies. In concluding this report, and in this connection, I desire to express my sincere thanks to the attach6s of this department for the willingness and zeal with which they have entered into the preparation of the annexed reports, for the perfection of which, in the limited time allowed us, they have labored with unremitting assiduity. -Hereto annexed-please find three statements, -showing in detail the value of stock received by this department during the months of September, October, and November, respectively, divided into twenty-nine classes, with the distribution of the same over the line of work, the prominent points of which are *given in the headings of the reports, and the remainder included in the heading "Miscellaneous," together with value, remaining in charge of this department November 30, 1872. Hoping that the next annual report from this department will be more complete and extensive, I am, very truly, yours, GEO. G. LYON, Chief of Supply Department and Auditor. Exhibit "A."

REPORT ON THE TOWN OF SUTRO. SUTRo, LYON COUNTY, NEVADA, -December- 31, 1572. ADOLPH SUTRO, Esq., General Superintendent. DEAR SIR: I herewith hand you my report of the town of " Sutro," together with a statement of the real estate sales made up to date. The town " Sutro" is situated in a broad valley, between two ranges- of nmountains running north and south, and upon a gentle easterly slope towards the Carson river, having a fall of 155 feet in 9,000, (the distance from the foot-hills to the river,) thlus insuring proper drainage for all parts of the town. Its extreme length from north to south is three and six-tenths miles; its extreme width from east to west is nearly two miles; its average length and width is dependent on the conurse of the river and the location of the company's property, as indicated on map. The town, as proposed, consists of fifty streets, First street commencing at the extreme south and extending to Fiftieth -at the extreme north, Adele avenue west, and Zelina avenue east. The portion of the town already laid out is, however, much less, as shown on the map, thoug-h, quite sufficient. for 5,000 inhabitants. It begins at 20th street on the south and extends to 3d on the north, and from Adele avenue on the west to Jeanne on the east. All the avenues and streets are unusually wide, which will add much to the health and beauty of the place, and when the groves of shade trees shall have attained a proper growth, it will be difficult to find a nmore~pleasant and agreeable place for business purposes and residences.in the State- of Nevada. 31 Twenty-Seventh street, the thoroughfare leading from the mouth lf the tunnel to the river, is 200 feet wide, and all other streets running parallel are 80 feet. Florence avenue is 150 feet, other avenues are 100 feet; and alleyways or narrow streets between blocks are 40 feet. There are also four public plazas or squares, 680 by 700 feet. aer-At present the supi)ly of water cornes from William Penn caflon and shaft No. 1, being conducted from both places by flumes and pipes to a large stone reservoir situate two hundred and fifty feet above the town, and capable of holding 5u,000 gallons of water. The Sutro tunnel also contributes quite a large supply; a stream of water 155 feet high can be thrown by direct pressure, without the aid of steam-power, through three-and-a-alf inch hose with five-eighths nozzle. We are thus, in a measure, prepared to resist fire should we be visited by it. Room is reserved for mill-sites, iachine-shops, &c., and when the tunnel s conleted tis will be, without doubt, the great center forredcing the ores of the Costock, as well as the rock from outside districts. There are many lgood ledges in the adjacent mountains, which, as soon as milling becomes cheap, will be worked to great advantage, producing to the world untold wealthi. Bicks.-At the eastern portion of the town an abundance of clay is found of the very best quality for brick-making; several kilns, containing 300,000, have already been burned, producing an excellent quality of brick. Soil.-The soil here in the valley is varied, the lower portion of the town, as now laid out, being decomposed tractyte, gravel, and vegetable matter, and where irrigated has hiroved extremely fertile, and as fine vegetables can be raised here as in any other part of the United States. Gas.-Arrangements have been made for the introduction of gas -into the town, a gas-house of suitable proportions having been erected, and a machine of the Atmospheric Gas Company, for generating the gas, has arrived and been put in operation, which gives'most satisfactory results. This, in addition to furnishing the town with gas, will be used in illuminating the Sutro tunnel. Telegraph.-Pofes for a hine of telegraph between this town and Dayton, some throe miles and a half distant, have been placed in position, and the Western Union Telegraph Company are now making arrangements to stretch their wires between the two places and establish an office here. It is also proposed to construct a telegraph line from the tunnel to the different shafts of the Sutro Tunnel (Company to Virginia City. Buildings.-Quite a ntmmber of buildings have been erected, mainly on Florence avenue, at present the main business portion of the town. The Sutro Building Association, a corporation organized for building purposes, with a capital of $50,000, divided into 500 shmares, of a par value ohf $100 each, has commenced the construction of a'large brick building, to cost about $15,000, the first story being already completed. The building will be two stories and a basement, the grJUnd floor to be occupied as stores, the upper part to be used as a Masonic and Odd Fellows' Hall, and for other public purposes. There are also the following business places in occupation and operation, Viz: a barber's shop, meat n~arket, hotel, several boarding-houses, billiard 32 saloon, and also a news depot and stationery store, in which the ost office is located. Quite a number of private residences have been erected, and several ore are in contemplation. Assay Office.-An assay office, with requisite facilities for making both bullion and ore assays, hais been fitted up by the cornmpany, in which tests of the rock both in the face of the tunnel and other parts of the line are daily being inad e. The prospects for a large increase of population next spring are dail improving, ad much interest is evinced on all sides relative to the future of the town, and inquiries are daily made not only at my office, but of the men employed by the company and by parties residing in adjoining towns, as to price of lots, eligibility for business, probable demand for certain kinds ofl business, etc., etc. It is to be hoped that the company will, as has been suggested, immediately proceed to erect a number of cottages for ret or sale to employs: this will not only be a great accommodation to many employed here, who cannot now find proper accommodations, and without adequate means to build for themselves. From the town the ~ountry to the north and east for many miles is very nearly level in character Over these plains to Wadsworth, a point on the Central Pacific railroad, distant some thirty-five miles, a railroad can be constructed at a comparatively trifling cost, and no doubt will be at an early day, as the location of the immense works necessary for the reduction of the ores of the Coinstock at this place will render such a work indispensable for the transportation of lumber, wood, coal, and -machinery, and the vast a-mount of general stores used by the tunnel company and reduction works, all of which are now transported at enormous cost and by a circuitous route of over fifty miles by. the Virginia and Truckee railroad from Reno to Virginia City, which latter place is nearly 1,800 feet above, the level of this town. I am, yours, very respectfully, DAN. J. BoUSFIELD. Paymaster and Real Estate Agent for rSutro Tunnel Company. 83 Statement of Real Estate Sales. o Q Purchasers' Names.

ADOLPH STRO, Esq., General Superintendent. DEAR Si: Having recently arrived at Sutro to take charge of the Hospital Department of the Sutro Tunnel Company, I beg leave to submit to you the following report; The town of Sutro is situated at the base of the Washoe range of mountains, gradually sloping eastwardly to the Carson river, commanding a beautiful view of the valley and surrounding mountains. Great care and good judgment have een manifested in laying out the town. The streets are wide and regularly laid out. All the lots are of good dimensions, and many have already been sold, and improved with suitable buildings; that will compare favorably with any town in the State of Nevada. Manyof the buildings are large, airy, and comfortable, adding greatly to the sanitary condition of the town. The climate cannot be surpassed for healthfulness on the Pacific coast, and is not subject to the many changes experienced in]our neighboring State of California. The atmosphere is pure, light, and dry, and at this season of the year although cold in the morning and evening, is delightful in the middle of the day. The water is excellent, being pure mountain water, and runs through the center of the town, affording an abundant supply for all necessary purposes. There are- at present about three hundred workmen employed along the line, a distance of- five miles, over a good road, passing by each shaft, where these men are employed by the Sutro Tunnel Company. Among the employ6s there is little or no sickness; and, indeed, I have never seen so large a -number of workmen together enjoy better health. Like all mining camps, we have occasionally'a case of surgery. Sutro has been particularly fortunate even in this branch of the- profession: no one having been seriously injured for some months past, (with a single excepti'on,) and that was a case of a poor man, who, shortlyl after his arrival here; fell into o'ne of the shafts and was killed. Having had so few injured I am sure is owing to the good judgment on the part of the managers of the company in the selection of -temperate and steady workmen. Among the most important buildings to be erected in the early spring will be the hospital building for those who are unfortunate enough to require medical aid and the comforts of a well-regulated infirmary., The hospital fund or tax imposed upon each individual employed by the company is now almost suffic ient to commence the building, which will be erected upon the most improved plan, and I have no doubt by spring we shall have sufficient funds to push the work on rapidly and pay for its completion. I trust, however, we shall have but little use for such a building, and I am certain that, if the same good judgment is carried out in the selection of workmen to carry on this gigantic work the coming spring and summer, I shall 35 be able to report favorably upon the general health of the employ6s of the Sutro Tunnel Company. Respectfully submitted, M. MCPHERSON, M. D. Resident Physician Sutro Tunnel Company. REPORT OF THE CHIEF OF THE MINING DEPARTMENT. SUTRO, LYON COUNTY, NEVADA, December 31, 1872t. ADOLPH SUTRO, Esq., General Superintendent. SIR The following brief resumd of the mining operations in connection with the Sutro tunnel is respectfully submitted: Work was commenced on this important enterprise on the 19th day of October, 1869, at which time but fifteen men were employed, and they only on day "shifts." Operations were conducted on this limited scale up to December 1, 1871, at which date the header, the only point where work was prosecuted, had been drifted a distance of 2,601 feet. Under the impetus given by the consummation of successful financial negotiations, the force was increased during the month of December, 1871, to 232 men; hoisting engines and steam pumps of moderate capacity were purchased for each of four shafts, which were laid out on the line of the tunnel, nearly equidistant from each other; buildings were erected at these points for hoisting works, boarding houses, offices, &c., and every arrangement made for prosecuting the work with energy and efficiency. The machinery obtained at this time was only calculated to carry the shafts down from 500 to 800 feet, below which depth it was expected that much heavier and more costly apparatus would be required. This has been procured and put in operation during the past season. When operations were commenced on this enlarged scale the force was divided into three "shifts" or reliefs, working eight hours each, and the work has been prosecuted day and night ever since. The miners receive four dollars in gold coin for each eight hours' work-better wages than laboring men receive in any other mining country. The four shafts referred to were laid out at the following distances from the mouth of the tunnel, viz: No. 1..................... 4,915 feet. No. 3.................... 13,545 feet. No. 2..................... 9,065 " No. 4..................... 17,695" The latter shaft is 2,450 feet from the Comstock lode, thus making the entire length of the main tunnel 20,145 feet. The depth of the shafts to the tunnel level will be as follows, viz: No. 1.................... 523 feet. No. 3..................... 1,361 feet. No. 2............. 1,041 " No. 4..................... 1,485 36 And the depth of the tunnel below the croppings, at the point where it intersects the Comstock, will be about 2,172 feet. An air-saft, 5 by 4 feet in the clear, 210 feet deep, located 2,252 feet from the moth of the tunnel, has been constructed and used for the purpose of conveying fresh air to the workmen in the header, and for hoisting out the rock and debris taken therefrom. By means of this shaft also a current of air is kept constantly in motion between the bottom of the same and the mouth of the tunnel, affording thorough ventilation for that distance. This demonstrates, on a small scale, the advantages that will accrue to the mines on the Comstock when they are connected with the tunnel. These shafts have been carried down to various depths, as follows, viz: NoI............... 454 feet. No. 3.................. feet. No2............... 623 " No. 4.................. 421 Great difficulties have been experienced at each point, principally on account of water; a large portion of the outlay, thus far, having been caused by efforts to get rid of this troublesome element, which for a "dry country is astonishingly prevalent. The header of the tunnel to this date has been drifted a distance of 3,451 feet. The size of the header is six by seven feet. The rate of advancement as averaged about two feet per day during the past year. The progress has necessarily been variable, owing to the difference in the character of the rock encontered. For instance, in the week ending September 13, 1872, but ten feet was drifted, the rock being propylite, or greenstone; the following week twenty feet were made, the rock being partly trachyte and partly propylite; the third week, being all in trachyte, an advance of fifty feet was noted. -The work in the tunnel, such as drilling, running the dump-cars, &c., has heretofore been carried on exclusively by hand labor, the modus operandi having been as follows, viz: Three men were employed in the header at on e time-one to hold the drill, the other two to strike. Two holes were drilled fro m two to five feet deep, according to the, nature of the rock, into each of which a cartridge of dynamite, or "giant powder,' was inserted. The cartridges are then exploded simultaneously by means of fuses and caps. This,explosion creates an opening of considerable size at the bottom of the drill holes, which is then filled, with ordinary black powder. This is fired off with a water-proof fuse, the men in each case retreating from 200 to 300 feet distant from the header until the explosion takes place. The result of each blast is to throw off large quantities of rock' which is loaded into small cars, -run out to the air-shaft, (1,200 feet,) and hoisted thence to the surface. It is proposed, however, to use diamond -drills in the tunnel, to be driven by water power, which is to be obtained in the following manner, viz: the water which is now pumped from shaft No. 3 (1,154 feet above the air-'shaft) will.be conveyed in a flume or ditch to the "divide," (a high ridge rising abruptly between shafts Nos. 1 and 2, and about 1,000 feet above the former,) where it will be collected into a reservoir, excavated for the purpose in the solid rock. It will be conducted thence down the mountain side to a large reservoir, formed near shaft No. 1 by, a dam, constructed across a deep 37 gorge in that vicinity. This reservoir will also accumulate a large quantity of water arisin from melting snow and winter rains. From this point a four-inch wrought-iron pipe has been laid to the air-shaft, a distance of over half a mile, thence down said shaft to the tunnel level, and will be continued along the tunnel to the header, where it will be applied as a motive ower to a "lurdy-gurdy" wheel, thirty inches in diameter, which will drive two. diamond drilling machines. This power will also be used to supply fresh air to the workmen in the header, by means of a small "hurdy-gurdy wheel placed at the bottom of the air-shaft to propel a blower, which will force the air through an eight-inch galvanized-iron pipe. Two Burleigh rock drills, similar to those in use in the Hoosac tunnel, have een procured, together with an air-compressor, which is to furnish the motive power to operate the same. These drills are mounted on a truck, which is to be run up to the face of the header, and, after the necessary number of drill-oles are made, will be drawn back to a safe distance until after the. blasts are fired off. By working the diamond and Burleigh drills side by side in the same rock and under similar conditions, the comparative advantages of each can be readily ascertained, and the one found the mnost advantageous will e adopted for the entire work. A track of T-iron rail, thirty pounds to the yard, has been laid from the mouth of the tunnel to the header, (3,455 feet,) and the debris is now being removed by means of cars drawn by mules. This track will be constructed to the river, a distance of 9,000 feet from the tunnel entrance, and will e used for the transportation of wood, which is floated down the Carson river to a point opposite the mouth of the tunnel. Itis also intended to convey water from the bottom of the air-shaft to the enlargement of the tunnel, (which has been completed and timbered for a distance of 1,100 feet, where it can be used to propel diamond drills, several of which can be worked to advantage at that -point. The rock, &c., from the enlargement of the tunnel will be carried away by small locomotives, which are being manufactured for the purnpose at Pittsburg, Pennsylvania. Many changes of rock have been encountered in drifting the tunne~l, whi ch are susceptible of a large number of geological divisions. They may, how:ever, be generally s~tated as follows, viz: from the mouth of the tunnel a belt of conglomerate, consisting of boulders of trachyte cemented together with volcanic tufa, extends for a distance of 650 feet; this is succeeded by a formation of coarse trachyte about 530 feet wide; then follows a seam of red clay (of which a coarse paint can be'made) 35 feet in width; following this is a belt of blue clay 150 feet; succeeded by porphyry, or greenstone, of varying hardness, 1 75 feet wide; a narrow seam of trachyte was then met, which was Bucceeded by propylite, extending to a distance of 3,000 feet from the mouth of the tunnel. Here trachyte was struck again, in which rock we are at present, (3,455 feet from the entrance.) ~Shafts Nos. 1 and 2 are being sunk in trachyte; 3 and 4 propylite. The full size of the tunnel as far as completed is 12~ 16 feet outside Qf- the timbers, which are 10-412 inches, except the inside posts, which are 10 inches 3quare. This is divided into two compartments, each 5 j feet wide at the 88 bottom, 4 at the top, and 10 feet high, with a passageway between, and drain underneath, as will be seen by the sketch on next page, marked Fig. 1. The top and sides are covered with "lagging," or sheathing, of two-inch plank. It is proposed to adopt a different style of timbering for the remainder of the tunnel, with the exception hereafter noted, using th arch form instead of that in figure 1. This may be seen on next page, Fig. 2. It is believed that it will be found necessary to use an elliptical brick arch through the red and blue clay belt heretofore mentioned, the ground being swelling," and ood not being of sufficient strength to withstand the pressure that will come upon it. The four shafts are of the same size, viz, 5+10 feet, divided into two com5partments, one + -the other 4/ 2"+5.' One division is used for hoisting rock, which is raised by means of a large wrought-iron tub, attached to a flat-wire cable, operated by a large steam engine at the surface. The workmen also ascend and descend in this shaft to their daily labor. The other compartment is used for supplying air and for pumping purposes. A series of ladders (each 15 feet in length, terminating at a platform, 20," from which another ladder descends in an opposite direction) is also erected in this division, forming a zigzag passageway from the surface of the ground to the bottom of the shaft. These ladders are intended for the escape of the workmen in case of fire or other emergency, the ascent and descent being generally effected as before described. It is proposed to substitute for these tubs cages, upon which small dump cars can be run, holding about a ton each. These will be filled with the broken rocks, the cages hoisted to the surface, and,the cars run out on the dump and emptied. These cages are now being constructed, and will be put in operation at shafts Nos. 1'and 2 about the.15th of January next. *The shafts are timbered with sets of timbers placed 5 feet from centers, the.outside pieces 10~12 inches; the posts 10+10 inches; the inside girth 10+ 14 inches. The " lagging," or sheathing around the outside of timbers, is of two*inch plank'; the lining is one-inch boards.' When' these shafts are sunk to the tunnel level, drifts will be comnmenced, about 6~7 feet, from the bottom of each; one running eastwardly towards the mouth of the tunnel, the other westwardly towards the Comstock lode, and connections will be made about midway between the shafts. This will give nine points from which to construct the tunnel, instead of one, as at present, and will reduce the time of its completion to that required to build a single tunnel half a mile long. *. Diamond drills will be used in sinking these shafts, two being provided for each, with the necessary engines and appurtenances. Those at Nos. 3 and 4 will soon be in operation, the rock being- much harder at those points than elsewhere on the line, and drills of this character being much more efficient in hard than in soft rock. These drills will be operated by steam power, supplied from the boilers at the surface. Fresh air is supplied to the shafts by means of blowers stationed at the top, the air being conveyed to the bottom through 8-inch galvanized iron pipes, and thence will be conveyed to the face of each drift when they are commenced. ! ~~~~~~~~~~~~~~~~~~~~~~ I A,z / x /;,19 / _.-=..-:- Ir _____________________ ~~~~~~~~~~-c —---- ~ 14/1 1 \\ I 9 I7T 40 Boilers and engines of the largest size and most approved construction have been set up at each point, and, every precaution has been taken to guard against any delay in the prosecution of the entire work. At intervals of from 275 to 300 feet in each shaft an excavation 10+10 feet and 40 feet long has been made, to receive the larger station pumps used for raising the water which accumulates so rapidly. At right angles' with these openings excavations 10+10 feet, 20 feet long, have been made for the reception of large tanks, or reservoirs, to retain the water raised from below; the pump above taking it from this tank, and the last one pumping it to the surface. Two of these stations have been constructed at No. 2, and one at each of the other shafts. Others will be added as greater depths are attained. Every precaution has been taken to guard against fires at the various points. Reservoirs are located on elevated positions, from which water can be promptly thrown upon the buildings in case of a conflagration. Scores of leather buckets are also kept constantly filled with water and placed in convenient positions around the hoisting works, ready for use at a moment's notice. At the mouth of the tunnel a reservoir with a capacity of 50,000 gallons has been erected, upon a hill to the westward of the town, from which the water is conveyed through a 4-inch wrought-iron pipe to various points. The pressure from this reservoir is sufficient to throw a stream 155 feet high through a 3-inch hose with a i-inch nozzle, thus affording ample protection to the machine shop, storehouse, dwelling house, and other buildings belonging to the company, which are located around the entrance to the tunnel, as well as to the various residences erected throughout the town. A large amount of grading and repairing of roads has been done by the company during the past season, one man being constantly employed upon the magnificent road constructed between Sutro and Virginia, to keep it in good condition; and it is now one of the finest highways in this part of the country. It is expected that with the new machinery recently erected and the increased facilities thereby afforded, much more rapid progress will be made hereafter, and we shall in a comparatively short time be enabled to announce to the world the completion of one of the greatest works of the age. To this end I am confident that you will have the hearty co-operation of every employ6 of the company. Respectfully, yours, R. P. DE Noon, Chief of Mining Department Sutro Tunnel Company. REPORT OF THE SUPERINTENDENT OF MACHINERY FOR THE YEAR ENDING DECEMBER, 1872. SUTRO, LYON COUNTY, NEV., January 1, 1873. To ADOLPH SUTRO, Esq., General Superintendent. This report comprises statements showing the distribution and kind of machinery owned by the Sutro Tunnel Company, and the work performed.therewith during the year 1872. 41 There are several places along the line of the tunnel where machinery is in use, as follows: 1st. The tunnel entrance at Sutro. 2d. The air shaft, 2,250 feet from the entrance. 3d. Shaft No. 1, 5,000 feet, 4th. Shaft No. 2, 9,065 feet, 5th. Shaft No. 3, 13,545 feetj 6th. And shaft No. 4, 17,695 feet from the entrance. As the machinery is so scalttered, it will be necessary to give an account of the same at each place separately, showing the progress and alterations for each successive month. In the commencement of the year 1872, the company commenced operations in a more extensive manner than they had been doing before. An engine and boiler were ordered for each shaft, and a large engine and boiler, with other machinery, were purchased from the " Lady Bryan Mining Company." Also a large quantity of tools and machinery was purchased in San Francisco, for the purpose of fitting out a machine shop at the tunnel entrance. THE TUNNEL ENTRANCE. January.-In this month a portable engine was running here for the purpose of forcing air into the tunnel header, to enable the miners to continue their work with greater facility, and to drive out the smoke from the powder which they used in blasting. The cylinder of the engine was 6/ by 9//, and the average steam pressure was 70 lbs. The blower run by this engine was a " Root's pressure blower," size No. 2, and is estimated to give 5 cubic feet of air per revolution The average running speed during the month was about 40 revolutions per minute, and the fuel consumed in the month was 23 cords of nut-pine wood. The air was conveyed along the top of the tunnel in galvanized iron pipes, about 8" in diameter, to the header, a distance of 2,700 feet. February.-The blowing machine was the only machinery in operation here this month. The average speed of the blower being 40 revolutions per minute. The average steam pressure was 70 lbs. Fuel consumed, 24 cords of nut-pine wood. The distance to the header, 2,750 feet. 2March.-During this month a machine shop 36 feet by 100 feet was erected, and furnished with a large assortment of tools and machinery, which had been ordered some months previous, but owing to the bad state of the roads it could not be got here sooner. A "Devoe and Dinsmore" engine, with steam cylinder 12z" by 30"/, was purchased from the "Lady Bryan Mining Company," and before being set up it was thoroughly repaired and all the working parts refitted. It was then bolted down on a solid foundation of masonry 8 feet deep, and when it was started up could be considered equal'to a new engine. The boiler was also purchased from the "Lady Bryan Mining Company." It is 48" diameter and 16 feet long. 42 April.-In this month the machine-shop engine was started up and the small blowing engine discontinued. The No. 2 Root blower was taken over to the machine shop, and connected to a countershaft run by the shop engine, and the blower was run at an average speed of 140 revolutions per minute. This increase in the speed of running the blower made the air in the tunnel clearer than it had been the previous month, and daylight at the entrance of the tunnel could be plainly seen from the header, a distance of 2,850 feet. The amount of wood burned by the shop engine and small engine combined was about 28 cords of nut pine. During the month the chief work done in the machine shop was on bolts and piping for the different shafts. Iron pipe was laid from the steam pump to two hydrants easy of access, and 100 feet of carbolized hose was furnished as a precaution in case of fire. May.-In the machine shop the following work was performed: boring and turning pulleys for the different machines, repairing the governor for the shop engine, making pipe connections for fire purposes at the different shafts, cutting thread on three-inch pipe for shafts Nos. 1 and 3, making new valves and piston for steam pump. The engine was run during the month at an average speed of 40 revolutions per minute, and the blower was run at an average speed of 140 revolutions per minute. The amount of fuel consumed was 29 cords. The average steam pressure maintained was 65 lbs., and the air was forced into the tunnnel 2,902 feet. June. —In this month an air shaft was completed, which connected the tunnel with the surface at a distance of 2,250 feet. The small blowing engine, which had been discontinued in April, was repaired and set up, to do the hoisting and blow the air into the header from the surface at the air shaft. This engine was originally a single engine, consequently, before it could be used as a hoisting engine, it had to be fitted with a link motion and new eccentrics, the crank shaft was pieced out and a pinion fitted to it, the piston was refitted, the valve seat faced down, the stuffing boxes bushed, and a new plunger made for the pump; the boiler was thoroughly cleaned, as it was found to need it very badly. The water space round the fire-box being very small was easily choked up, as the water that had been used contained considerable alkali, and large pieces of this incrustation were found in the bottom of the water space. This was occasioned by not having sufficient facilities for cleaning out the water space. Handholes were therefore made so as to prevent an occurrence of this kind in future. The hoisting reel and gear for th'is engine were chiefly made from some of the old material purchased from the "Lady Bryan Mining Company." The whole of this hoisting engine, with tank, water pipe, hoisting gear, and gallows frame complete, was in place and running on the 16th of June, being just twenty days from the time that work was commenced on it. The rest of the work performed in the machine shop this month was on bolts and piping for the several shafts and repairs of machinery. The shop engine averaged 40 revolutions per minute, an average pressure of 65 lbs. of steam was maintained, and the fuel consumed was 32 cords of 43 nut-pine wood. The blower was run at an average speed of 140 revolutions, and the tunnel header was in a distance of 2,940 feet at the end of the month. July.-This month the "Root blower" was moved to the air shaft and connected with the small hoisting engine, and the engine at the machine shop discontinued running all night, as it had done previously. The principal work done in the machine shop was work connected with the arrangement of the blower at the air shaft and repairs of steam pump for the several shafts, bolts, and piping and engine repairs for the shafts, turning car wheels for the tunnel. The speed of the shop engine averaged 40 revolutions per minute, and the average steam pressure maintained was 60 lbs. Fuel consumed 28 cords of nut-pine wood. During the month drawings for the new hoisting works were prepared, showing the arrangement of the machinery, boilers, and piping; also, plans for the hoisting works, gallows frames, &c., with estimates for the building material to be ordered for the same. The tunnel header was in a distance of 2,976 feet. August.-The work done in the machine shop this month consisted of repairs on steam pumps from shafts Nos. 1, 3, and 4, laying gas and water pipe in the office building, repairing the drill press, and making bolts and nuts for the new hoisting works. The tunnel header was in a distance of 3,097 feet. September.-The work done in the machine shop was principally for the new machinery being erected at the different hoisting works, and consisted chiefly of 10-inch steam-pipe connections, alteration of details of the new machinery, and repairing the old hoisting engines. Several diamond drilling machines arrived from the east this month, and were set up and tried in the shop. One of them was put in operation, and gave the following results: 542 feet of holes were drilled in thirty days, including the time occupied in moving the machine and the large girder it rested on. The drilling was done in a side-hill embankment at the tunnel entrance. The nature of the ground varied considerably, and consisted chiefly of conglomerate, cement gravel, and trachyte, and it was found far more difficult to drill than if it had all been hard rock, in consequence of the drill being subjected to uneven strains, by one side of it coming in contact with, perhaps, a piece of agate, whilst the other side would be conglomerate. But the chief disadvantage in drilling in this comparatively loose and seamy earth was, that the holes became so uneven by pieces of rocks, &c., falling around the sides of the drill and making the holes irregular in shape, causing the bits to catch when they were withdrawn; and by this means a number of diamonds were lost out of the bits. The bits used were of solid brass, and contained 20 diamonds each. They were 1"/ diameter, and were dished out in the center, so as to make them run straight. Water is conveyed down the drill rod, and is ejected through three small holes in the drill, under a pressure of about 40 lbs. to the square inch. The deepest hole drilled was 224 feet, and the average depth of the holes was 10 feet. They were charged with black powder, a 44 chamber being previously made at the bottom of the hole by exploding a piece of giant. The excavations made by the aid of this drill amounted to about 10,000 cubic yards, and was cleared for the purpose of erecting a new carpenters' shop and blacksmiths' shop at the tunnel entrance. The machine-shop engine averaged 40 revolutions per minute. An average pressure of 58 lbs. of steam was maintained, and 34 cords of nut-pine wood were consumed. The steam for running the diamond drill was conducted to it by 1"/ gas pipe. The drill used for this experiment was one of Allison & Bannan's make, was run at a speed of 500 revolutions per minute, with a feed of one inch to every 500 revolutions. October-The machine shop was kept busy this month, making flanges, pipe connections, and alterations in the details of the new hoisting engines at the different shafts. A punching machine for iron pipe was made, a new planer chuck was finished, and considerable work done on tools and appliances for use in the machine shop. The engine was run an average speed of 40 revolutions per minute, and 60 lbs. steam pressure was maintained. The fuel consumed was 32 cords of wood. November. —The machine shop was doing a large amount of work this month for the Allison & Bannan steam-pumps. A large amount of 10-inch cast-iron pipe had the flanges turned and holes drilled for connecting the pieces together. The planer was kept constantly running on the large 10/" elbows, which are used for making the suction connections to the large pumps. A large amount of 3/" and 4/" pipe had threads cut on both ends, and flanges turned and fitted to them. This pipe was used at the different shafts for connecting the pumps and other machinery to the boilers. A large water reservoir was connected to the hydrants at the machine shop, and to the supply pipe of the town of Sutro by 3" gas pipe. This reservoir is half a mile from the machine shop, and about 200 feet higher. It is supplied by water from a tunnel in the mountain some 50 feet higher, and can also be supplied by a pipe coming from another large reservoir at No. I shaft, nearly 300 feet higher, and over half a mile distant. About one mile of 2/ water pipe has been laid in the principal streets of Sutro, and at any time a head of 250 feet can be turned into them. At pressent the town is supplied with the tunnel water only, which is found to be more than sufficient. Steam pipes, water pipes, and gas pipes have been laid from the machine shop to the office building, and every room in it supplied with water, steam, and gas. The amount of fuel consumed at the machine shop this month was 32 cords. Average steam pressure maintained 60 lbs. December.-During this month the machine shop has turned out two new dump-cars, of a capacity of 21 tons each. These cars are constructed to be hauled out of the tunnel by a mule; each car is supplied with a brake, and all the latest improvements have been made on them. They are easily dumped, and are of a convenient height for filling. Four cages of the most approved plan are now being made, and will be finished in a few days. There are 45 quite a number of large castings being fitted up in the shops this month; most of them are pipes and elbows 10" diameter inside. A hurdy-gurdy wheel has been fitted.to one of the diamond drilling machines, to be used in the tunnel header, and will be run by water from one of the reservoirs under a pressure of over 200 pounds to the square inch. One of these wheels is also being fitted.up to run a blower, so as to dispense with the engine and save fuel. A large amount of steam and water-pipe for the different shafts is being fitted up, and parts of the small steam pump at shaft No. 4 are being refitted. Several hundred feet of galvanized iron pipe have been used, some of it 8// diameter, of No. 16 iron, for exhaust pipe.

June.-This shaft is situated about 2,250 feet from the tunnel entrance, and the connection was made between it and the main tunnel in this month. On its completion the air descended the shaft, producing a current in the direction of the tunnel entrance, but -since the tunnel has been widened out to the distance of one thousand feet the current changed, and is now from the entrance of the tunnel and up the shaft. A small hoisting engine was fitted up at the machine shop and was set up at this shaft, for the purpose of hoisting the rock from the tunnel header, so as to save the trouble of running it out in a car the whole length of the tunnel to the entrance. At this time also the tunnel was being widened out to its full size, and timbered from the entrance in towards the header. The chief object of running a car out from the header was the difficulty of maintaining a track where the work of widening was going on; to do this it would cause considerable delay and difficulty, and it was proved more expedient to hoist the rock at the air shaft than to run it out through the tunnel. The engine was started up here on the 16th, and during the month consumed 7 cords of wood. The average steam pressure maintained was 50 lbs. The tunnel header reached a distance of 2,940 feet at the end of the month. July.-This month the No. 2 Root blower was connected to the small hoisting engine here, and was kept running between hoists. It is so arranged that the belt which runs the blower is thrown off as soon as the engine starts to hoist, and is thrown on again while the engine is lowering. The average steam pressure maintained during the month was 55 lbs., and 15 cords of wood were consumed. The boiler of this engine was fitted with a new set of flues this month, as the old ones had become leaky on the fire-box end. August. - The engine was hoisting about 13 car-loads of rock from the header in 24 hours, and blowing in air to the header, which was in a distance of 3,097 feet at the end of the month. The average steam pressure maintained was 55 lbs., and the amount of fuel consumed was 15 cords. Average speed of running blower 120 revolutions per minute. September.-The engine here hoisted about 14 car-loads of rock; an average steam pressure of 55 lbs. was maintained; and the blower was run an average speed of 120 revolutions per minute. The consumption of fuel was 17 cords. October.-The engine hoisted an average of 14 car-loads of rock every 24 hours; maintained an average steam pressure of 55 lbs.; and the blower was run an average speed of 120 revolutions per minute. The distance of the header from the face of the tunnel was 3,170 feet. Wood consumed 16 cords. November.-The engine run with about the same results as last month. Fuel consumed 15 cords. )December. —Discontinued hoisting the rock; as the widening was discon 48 tinued, it could be run out in cars to the entrance. The header is now in 3,455 feet. SHAFT NO. 1. January.-This shaft was hoisting rock by means of a windlass this month. February.-In this month small hoisting works were erected here, and a Hoadley portable engine, with suitable hoisting gear and gallows frame, was placed in position. The dimensions of the cylinder of the engine was 9" by 12", and the boiler was a locomotive tubular boiler, 30" diameter. During this month the water came into the shaft at the rate of 2,000 gallons in 24 hours. The shaft attained a depth of 105 feet at the end of the month,,and 17 cords of wood were consumed. AMarch.-Water was struck in this shaft to the amount of 60,000 gallons in 24 hours, and a No. 4 Cameron steam pump was put in operation in the shaft, within 10 feet of the bottom. The steam was conducted to the pump by 1// gas pipe, in 10 feet lengths, with flanged joints, bolted together with a// bolts; 3" gas pipe was used for the water column, and 8// galvanized iron pipe for the exhaust steam. It was expected by some miners that the heat of the steam would make it uncomfortable for working, but this difficulty was entirely overcome by causing a free circulation of air in the shaft. This was accomplished by closely boarding the dividing timbers between the pump shaft and the hoisting shaft, and carrying close boarding up from the top of the pump shaft through the roof of the building, thereby making the actual opening of the pump shaft some 20 feet higher than the hoisting shaft, and the air being more rarefied in the pump shaft, it ascended, and thereby caused a continual downward current of fresh air through the hoisting shaft. A new boiler, 48// diameter and 16 feet long, from the Risdon Iron Works, San Francisco, was put in operation here this month, as the boiler of the portable engine was inadequate for the supply of steam for the pump and engine also. The hoisting engine this month averaged about 160 hoists in the 24 hours, and notwithstanding the large amount of water, the shaft progressed 47 feet, making the depth at the end of the month 152 feet. The portable engines at each shaft are all the same size and make, and the rock is hoisted in an iron bucket. The average weight of this bucket, when full, is about 980 lbs., the' bucket itself weighing 290 lbs. This bucket was dumped on arriving at the top into a car by means of a trip line, the door of the hoisting shaft being closed during the time to prevent the possibility of any rock falling into the shaft. April.-In this month the water caused considerable trouble here, there being over three millions gallons pumped from the shaft during the month. Much damage was done to the pump by the sand and gravel cutting out the packing and wearing away the cylinder and glands. The brass lining of the pump cylinder had to be taken out and a new piston made. During these repairs the pump had to be raised by means of a chain tackle twice, (10 feet each time,) in order to keep it out of the water, so that the machinists could continue their work, and in the 24 hours that it took for these repairs the water rose 36 feet in the'shaft; at the same time the hoisting engine was hoisting water as rapidly as possible in a tub constructed for that purpose. 49 Fuel consumed 70 cords; progress in the shaft 13 feet; depth at the end of the month 165 feet. -May.-On the 20th of this month another steam pump was put in the shaft. This was a No. 5 Cameron pump, and is double the capacity of the No. 4 pump, and discharges about 40 gallons per double stroke. The small pump was used as a sinking pump: that is, it was kept within about 15 feet of the bottom of the'shafts, to keep the water out of the way of the miners, and it discharged its water into a tank placed in a recess (or station) about 185 feet from the top of the shaft. This tank was arranged in such a manner as to catch all the water that came into the shaft above it, thereby preventing this water from going to the bottom of the shaft. The Cameron No. 5 pump took its water from this tank, and was run at an average speed of 24 double strokes per minute. About four millions of gallons of water were pumped from the shaft this month. The progress made in sinking this month was 35 feet, and the shaft attained a depth of 200 feet at the end of the month. Both boilers were used most of the time, and an average steam pressure of 70 lbs. was maintained, and 70 cords of nut-pine wood were burned. June.-The pumps and hoisting engine here gave less trouble this month, as the water diminished to about 100,000 gallons in 24 hours. The 48// boiler was used all the month, and an average pressure of 75 lbs. of steam was maintained. The consumption of fuel was 63 cords of nut-pine wood. The shaft was sunk 63 feet, making it 263 feet deep at the end of the month. The hoisting engine made 2,875 hoists during the month. July.-The water pumped from the shaft this month amounted to two and a half million gallons. The hoisting engine made over 5,000 hoists, and the shaft was sunk 61 feet, making it 324 feet deep at the end of the month. An average steam pressure of 65 lbs. was maintained, and 64 cords of wood were consumed. August.-On the 9th the Cameron pump No. 4 was put down the shaft to a depth of 333 feet, and was kept constantly running an average speed of 60 double strokes per minute. The No. 5 Cameron pump was run an average speed of 34 double strokes per minute, and nearly 5,000,000 gallons of water were pumped from the shaft. The fuel consumed was 94 cords of pine wood. The shaft at the end of the month was 374 feet deep. September.-The hoisting-engine made 4,200 hoists. The large pump was run 34 strokes per minute, and the small one 60 strokes. The amount of water pumped was about five million gallons during the month. An average steam pressure'of 90 lbs. was maintained, and 136 cords of wood were consumed. The shaft progressed 58 feet during the month, making it 432 feet deep at the end of the month. October.-During this month two 54-inch boilers were set up, and the 48inch boiler torn down and set up in a different place, so as to bring it in its proper position in the new building. A new hoisting engine was set up; the size of the steam cylinder is 14" by 27"/, and it was built at the Risdou Iron Works, San Francisco. The old portable engine was removed and placed so as to hoist from the pump shaft, after having made 3,000 hoists during the 4 50 month. The new Risdon engine was started up on the 28th, and made 610 hoists. The 48-inch boiler was used up to the 15th, and then the 54-inch boilers were started up. The average steam pressure carried while using the 48-inch boiler was 90 lbs., and the pressure carried on the 54-inch boilers was 65 lbs. The amount of wood burned this month was 125 cords. The water pumped from the shaft amounted to about three and a half millions gallons. November.-The number of hoists made during the month was 1,600. The two 54-inch boilers were used, and an average steam pressure of 80 lbs. was maintained. Nearly three millions gallons of water were pumped from the shaft. December.-Up to the 22d of this month 1,320 hoists were made. The two 54-inch boilers were used, and an average steam pressure of 80 lbs. of steam was maintained. The amount of fuel being consumed this month is 6 cords'per day. The pumps are working well. The No. 4 Cameron pump is 450 feet from the surface, and the No. 5 is 290 from the surface. The amount of water being pumped this month is 5a miners' inches, which is equal to 97,750 gallons every 24 hours. This has been accurately ascertained, and affidavits of the superintendent of machinery, the chief draughtsman, and the engineer in charge at the shaft have been taken, certifying to the accuracy of this statement. The machinery, &c., on hand is as follows: One horizontal hoisting engine, with cylinder 14//x27/, from the Risdon Iron Works, San Francisco. There are 700 feet of steel-wire rope here, 3" wide and /" in thickness, on the hoisting reel, and a spare one of similar dimensions is ready to replace the other in case it should be required. One Hoadley engine, 9/x12// cylinder, is placed so as to hoist in the pump shaft, to assist in getting in large pipes and lowering pumps. This engine also runs a circular saw for the carpenters, and is intended to run a blower as soon as it is needed. One Allison & Bannan steam pump, with cylinder 20/' diameter and 6-feet stroke; water cylinders 10" diameter and 6-feet stroke. This pump is doubleacting, and when complete weighs 10 tons; not yet in use. One Allison & Bannan single-acting sinking pump, steam cylinder 20"/ diameter and 4-feet stroke, water cylinder 10" diameter and 4-feet stroke, weight 5 tons; not yet in use. One Cameron pump, size No. 5, steam cylinder 12//x12//, water cylinder 7//x12"/; in shaft at work. One Cameron pump, size No. 4, steam cylinder 10/"x10/", water cylinder 5"//x10//; used as a sinking pump. One Blake pump, with water cylinder 4"/x10//, used for feeding boilers, and connected with hydrants, to be used in case of fire. One No. 4 Root blower, not in use. Two tubular boilers, 54" diameter, 16 feet long, with flues 3/-" diameter. These boilers are set separately, in substantial brick-work, and each is furnished with a cast-iron boiler-front. 51 One 48-inch boiler, with 3~-inch flues, with cast-iron boiler-front, set in brick-work. This shaft is furnished with the necessary amount of 10-inch pump pipe for sinking the shaft, and enough steam pipe is on hand to reach the bottom of the shaft when completed, which will be about 530 feet. The present depth of the shaft is 452 feet. The following is the number of men in the machine department: Rate. One chief engineer of the shaft.................................................... $6.00 Two engineers......................................... 5.00 One oiler and storekeeper, &c........................................ 4.00 Two firemen............................................................................ 4.00 One machinist...............................................5....................... 5.50 Three pumpmen........................................................................ 4.25 The main building is 75 feet long and 36 feet wide. The boiler house'is 36 feet by 40 feet, and the carpenter shop is 36 feet by 40 feet. The blacksmiths' shop is not connected with the main building, as a precaution against fire. SSHAFT NO. 2. January.-A windlass was being used at this shaft during this month for hoisting the rocks, the machinery not yet having arrived from San Francisco. February.-This month a Hoadley portable engine was put up at this place. The size of the cylinder was 9" by 12". The fuel consumed was 8 cords, and the shaft attained a depth of 240 feet at the end of the month. ZMarch.-During the month the hoisting made 4,000 hoists. The average steam pressure maintained was 70 lbs, and 23 cords of wood were consumed. There being no water in this shaft, it progressed more rapidly than the others. 67 feet were sunk during the month, and the shaft attained a depth of 307 feet at the end of the month. The consumption of fuel is lighter at this shaft than any of the others in proportion to the work done, which can be accounted for by the fact that the boiler,is supplied with clear water from a spring, the water of which contains but little alkali, while at shafts Nos. 1, 3, and 4 the water raised from the shafts is used for feeding the boilers; and as it contains a large proportion of earthy matter, it forms a thick scale in the boilers, and to obviate this as much as possible it necessitates their being blown off repeatedly, thereby causing a loss of fuel, which, in addition to the non-conductive properties of the scale remaining around the flues of the boiler, amounts to considerable in the course of the month. April.-A new boiler 48/" diameter and 16 feet long, with flues 31/- diameter, built by the Risdon Iron Works Company, San Francisco, was set up here this month. This month water was struck here to the amount of 7,000 gallons in 24 hours. This was hoisted out with the rocks without difficulty. The engine made about 4,200 hoists. The average steam pressure maintained was 75 lbs., and 24 cords of wood were consumed. 52 The shaft progressed 93 feet, and was down 400 feet at the end of the month. May. —The new 48/ boiler was fired up on the 13th and the small boilei discontinued. An average steam pressure of 70 lbs. was maintained. The engine made 4,500 hoists. The water hoisted from the shaft amounted to 2,000 gallons in 24 hours 30 cords of wood were consumed; part of this was Carson pine and part nut pine. 83 feet progress was made, and the shaft was 483 feet deep at the end of the month. June.-The water increased this month to an average of 10,000 gallons in 24 hours. The 48// boiler was used throughout the month, and an average pressure of 75 lbs. of steam was maintained. The fuel consumed here this month was 37 cords' of Carson pine. Sinking progressed 55 feet, making the shaft 538 feet deep at the end of the month. July.-The engine here made 5,600 hoists during the month. The average steam pressure maintained was 75 lbs. The average amount of water coming into the shaft was 1,800 gallons in 24 hours. This was hoisted out with the rocks without difficulty. The progress in sinking was 57 feet, making the shaft 595 feet deep at the end of the month. August. —The engine here made 4,200 hoists during the month; the average steam pressure maintained was 60 lbs.; the amount of wood burned waa 26 cords. Th'e progress made in sinking was 5 feet, and excavations were commenced for two large pump stations, each 40 feet in length and 10 feet x10O feet outside timbers, with tank stations 20 feet long cut at right angles to them.' These pump stations are for the Allison and Bannan steam pumps. The shaft was 600 feet deep at the end of the month. September.-The Hoadley engine was removed on the 10th, having made 1,200 hoists up to that tinme. The 48" boiler was used up to the 10th, and then it had to be removed so as to be placed in its proper position in the hoisting works that were being erected at this time. Two new tubular boilers from the Union Iron Works, San Francisco, were set up here, and steamed up on the 19th. They are 54-inch diameter and 16 feet long, with flues 35-inch diameter. They are fitted with a cast-iron boiler-front, steam drums, and all the necessary connections, safety valves, -stop valves, &c., and are set together in brick-work, so as to be both used at the same time. A new horizontal engine, built at the Union Iron Works in San Francisco, was erected, with hoisting reel, gearing, brake, and every thing else complete. The whole is set on a solid foundation of stone masonry, containing about 385 perches, and is securely bolted down by bolts 14 inches diameter, passing through anchors at the bottom of the foundation, which is 15 feet deep. This engine made 1,300 hoists up to the end of the month, and all its parts worked admirably. Fuel consumed was 26 cords. October.-The new 54// boilers were used all this month, and an average steam pressure of 60 lbs. was maintained.. There were 78 cords of nut-pine 53 wood consumed during the month. The cable had to be changed here this month on account of the interior strands bulging up at a place about 2 feet off the reel when the cable was unwound, so as to reach the bottom of the shaft. The pump stations were nearly completed this month, and portions of the large pumps were lowered down the shaft. An extra boiler 48"// diameter and 16 feet long was set up here this month, to be used with the old 48// boiler, so as to give time for cleaning or repairs on the 54" boilers. The engine made 4,300 hoists during the month. November. —The chief work done here during the month was fitting up the two large pumps. One of them is in a station 275 feet from the surface and the other is in a station 550 feet from the surface. Each of these pumps weighs 10 tons, and the bed plate that they rest on is 30 feet long. The steam cylinder is 20-inches diameter and 6 feet stroke, the plungers are 10-inches diameter, and the pump is a double-acting pump, constructed with two plungers and two sets of valves, or otherwise-two single-acting pumps connected to one steam piston. The column through which the water from these pumps passes to the top of the shaft is of wrought-iron with cast-iron flarges, and is 10-inches diameter. This column is securely braced and supported by the shaft timbering. The shafts at all the places are 10 feet long in the clear and 5 feet wide, and the timbering is 10"x12//, in sets 5 feet apart, supported by corner posts 10//x10//. A girt of 10//x12/ timber divides the hoisting shaft -from the pump shaft, making the hoisting shaft 4'.2"x5'.0" in the clear, and the pump shaft 5/.0x5/.0// in the clear; boards are nailed on the girts so as to make each shaft independent, and a ventilator box is carried up through the roof of the building over the pump shaft, so as to cause a circulation of air down the hoisting shaft and up the puimp shaft. The water column from the second pump discharges its water into a tank at the first pump station; from thence it is pumped by the pump at that place and discharged into tanks at the surface. And this means of passing the water from one pump to the other will be continued as more pumps are put in the shaft. The steam pipe is of wrought-iron, and is 6"/ diameter down to the first pump, 5" diameter to the second pump, and will be diminished in size proportionately as more pumps are put in. The steam is conducted along the pump station from the main pipe to the pump by 3-inch wrought-iron pipe at each pump. The suction pipe from the tank to the pump is 10/ diameter, and is chiefly cast-iron. The water is made to pass through a condenser before coming to the pump. This condenser is placed at the back end of th% pump station, and can be used at pleasure by opening a valve, which will turn the exhaust steami through the condenser' instead of conducting it to the exhaust box. The exhaust box is of wood, 12"/x12// internal area, and the exhaust steam from all the pumps is turned into it, and by it carried to the top of the shaft. The water which may overflow from the pump stations is also conducted into this box, so as to prevent it splashing in the shaft. All the steam pipes and exhaust pipes are covered with thick cow-hair felt, sewn up in canvas and painted; and notwithstanding this precaution the heat in these stations is ftoquently over 100 degrees. 54 The condensers are made of cast-iron; they are 3 feet diameter and 6 feet long. They are something new, and are patented by Henry L. Brevoort, of New York, from whom they were purchased. The water is taken in from the side, and passes up to the top through an annular space, thence through an annular adjustable valve, where it is formed into a sheet jet, through which the exhaust steam is made to pass. The amount of pressure to the jet is regulated by a float, and the water can also be regulated by hand. We have not yet tried these condensers sufficiently to pass an opinion on them, but they will probably save fuel. The number of hoists made here this month was 4,297. The two 48/" boilers were used, and an average steam pressure of 60 lbs. was maintained. The fuel consumed was 99 cords of Carson pine. The quantity of water pumped from the shaft was 68,900 gallons in 24 hours. December.-The two 48// boilers are being used this month, and the average steam pressure maintained is 74 lbs. The engine averages about 70 hoists per day of 24 hours, and the shaft is now 622 feet. The large pumps are working a little more than 2 strokes per minute, at which speed they hold the water easily. A number 7 Knowles pump is being used at the bottom of the shaft as a sinking pump, and is being run about 22 strokes per minute, and discharges a little less than 2 gallons per stroke. Most of, the water coming into this shaft comes in at the bottom and the rest comes in at the lower pump station, and is caught up in the tank at that place. The amount of water now being pumped from this'shaft is 34 miners' inches; equal to 68,000 gallons in 24 hours. Affidavits of the superintendent of machinery, draughtsman, and engineer in charge have been made to this effect. The fuel being now consumed averages 8,000 lbs. of coal per day of 24 hours, and the average amount of wood consumed is 44 cords per day when not using coal. The wood used is Carson pine. The amount of lubricating oil used per day averages 24 pints; the coal oil averages 2 pints; the tallow 2 lbs. The machinery atpresent on hand is asfollows: One horizontal hoisting engine, with reel, hoisting gear, brake, and all necessary attachments complete: size of cylinder 16// by 27//.

Rocky Mountain coal was used for 22 days, and the amount burned during that time was 132,000 lbs. 60 pints of lubricating oil were used, 60 pints coal oil, and 120 lbs. of tallow. The new hoisting works are nearly finished. They are the same size as the hoisting works at the other shafts, and differ only by having both wings on the north side of the main building, while at shafts Nos. 1, 2, and 4, the wings are on either side of the main building. December.-The average number of hoists per day made by the engine is 200. The pair of 54// boilers were used from the 1st to the 12th, and from the 18th on. The Babcock and Wilcox boiler was used from the 13th to the 17th. Wood was used for 9 days at the rate of 6 cords per day, and coal (Rocky Mountain) is now being used at the rate of 7,000 lbs. per day. The pumps are in the same positions as in November, and are now in a fair state of repair. The amount of water being pumped from the shaft this month is 153,000 gallons in 24 hours. This amount has been accurately measured, and is certified to in affidavits made by the superintendent of machinery, chief draughtsman, and engineer in charge. The machinery at this shaft is as follows: One hoisting engine, 18" by 27", built at Booth & Co's, San Francisco. One Hoadley portable engine, 9/ by 12"/, used for hoisting in the pump shaft, running circular saw, and can be made to run blower when necessary.
