C.-This work was commenced under an appropriation made in the act of Congress approved July 15, 1882. The plan consisted of raising the dam in the Maryland channels at the Great Falls of the Potomac to an elevation of 148 feet above mean tide at the Washington navy-yard, and its extension, at that height, across Conn's Island and the Virginia channel of the river; extending the Washington Aqueduct from the distributing reservoir above Georgetown to the site selected for the new reservoir, near Howard University, by a tunnel 20,696.3 feet long; constructing at the tunnel outlet a new reservoir of about 300,000,000 gallons capacity, and con *$20,000 for maintenance and repair of the aqueduct; $60,000 for commencing the improvement of the receiving reservoir. necting this reservoir by a new line of large mains with the existing system of water mains in the city of Washington. All operations on this project are suspended, and no work has been done under it during the year. The channel on the east side of the reservoir, which has been damaged by heavy rain, was repaired in August, and a strong bulkhead was built with a flume leading from behind it into the great sewer that passes around the reservoir. The paving of the ditch at this point was laid in cement, and it is hoped that future damage at this troublesome place will be avoided. The necessary repairs were made to the watchman's house at the reservoir during September and October. A new protection over the top of the Fayette Street air shaft was made in November. Stone was hauled, by permission, by the District of Columbia from Champlain Avenue shaft for repairs of roads. A deed of Frederick Wetzel to the United States, for land near the distributing reservoir, dated April 26, 1890, with quitclaim deed of Margaret A. Wetzel, dated May 2, 1890, was recorded on January 18 in the land records of the District of Columbia. The following provisions were incorporated in the act making appropriations for the District of Columbia, approved by the President March 3, 1883: That notwithstanding the limitation prescribe by the acts of Congress, approved July fifteenth, eighteen hundred and eighty-two, and February twenty-six, eighteen hundred and eighty-five, the Secretary of War be, and he is hereby, authorized to pay to Thomas Keady the sum of four hundred and seventy dollars and ninety cents, out of the unexpended balance of the appropriation of fifty-one thousand three hundred and seventy dollars, to pay for land to extend aqueduct, made by the act entitled "An act to increase the water supply of the city of Washington, and for other purposes," approved July fifteenth, eighteen hundred and eighty-two, which sum shall be in full for the appraised value of land owned by the said Thomas Ready and taken by the United States for the requirements and purposes of that act: Provided, That no payment hereunder shall be made until the the Attorney-General shall have decided that an absolute title to the premises shall vest in the United States. A watchman has been employed during the year at the new reservoir. His duties have included the guarding of the stone at the mouths of all the shafts, except the one at Foundry branch, which is under the care of the watchman at the distributing reservoir. July 1, 1892, balance unexpended on all items of appropriation..... July 1, 1893, balance unexpended and available..... No estimate for further appropriation is submitted.

Sections 4, 5, and 6 of the fish ways at Great Falls were completed at the date of the last annual report of the officer in charge, and there remained to complete the plans of the Commissioner of Fish and Fisheries sections 1, 2, and 3. Under a ruling concerning the act of July 15, 1882, providing for the construction of these fish ways, the Secretary of War decided that the engineer officer in charge should be held responsible only for the proper protection of the Aqueduct Dam at Great Falls and the disbursement of the funds appropriated, the Commissioner of Fish and Fisheries being responsible under the act for the plans and specifications of the fish ways and their execution. By the act of Congress approved by the President August 5, 1892, an appropriation of $15,000 was made for this work. Proposals were advertised for October 17, and the contract, which was awarded to Mr. Isaac H. Hathaway, of Philadelphia, Pa., the lowest bidder, was entered into November 23. During August and September a surveyor and three men were employed on a survey for the purpose of enabling the Commissioner of Fish and Fisheries to make the construction plans for sections 1, 2, and 3, and also for an additional work desired by him, viz, a permanent dam between sections 1 and 2. Upon application by the contractor, and with my authority, the time for the completion of the contract was extended one month. Sections 2 and 3 of the fish ways and part of the permanent deflecting dam have been completed, but there remains to be done the completion of this dam and the construction of section 1. The Commissioner of Fish and Fisheries is of the opinion that an additional sum of $7,890 will be required to complete the work, and requests that an estimate for it be submitted. Amount deemed necessary by the Commissioner of Fish and Fisheries for the completion of the work... (See Appendix B B B 3.) 7,890.00 IMPROVEMENT AND CARE OF PUBLIC BUILDINGS AND grounds, AND CARE AND MAINTENANCE OF THE WASHINGTON MONUMENT, IN THE DISTRICT OF COLUMBIA. Officer in charge, Col. O. H. Ernst, Major, Corps of Engineers, until March 31, 1893, and since that date, Col. John M. Wilson, Lieut. Col., Corps of Engineers. The Executive Mansion has received the usual care, and such improvements have been made as the funds available would admit. Neufchatel mastic has been laid upon the area pavements and in a portion of the basement of the building. The heating apparatus was remodelled and improved. Some of the interior walls have been redec orated and rooms refurnished. Those portions of the stone balustrade, coping, cornice, etc., of the building which were torn away and seriously damaged during the severe storm in November, 1891, were repaired. New furniture, matting, carpets, etc., have been supplied from time to time when necessary. The conservatory and greenhouses were all overhauled and repairs of various kinds made. Every effort has been made to maintain the Washington Monument and its machinery in good condition, and to continue the improvement and ornamentation of the adjacent grounds. All boilers and machinery have been carefully overhauled and cleaned, and the work of repainting the iron work of the interior of the monument has been commenced. The elevator receives the most careful attention, being constantly inspected by experts, and it is believed to be as safe as it is in the power of man to make it. There were 186,327 visitors to the top of the shaft during the year, making a total of 799,502 persons who have made the ascent since the monument was opened to the public in October, 1888. The improvement of the monument grounds has been continued, plank walks constructed, new water pipe introduced, flower beds planted, etc. At the propagating gardens and nurseries extensive repairs were made to the various greenhouses, about a half million plants propagated for use in the public parks, shops and storehouses repaired, and a large number of cuttings of flowering shrubs planted. In addition to the general work performed for maintaining in good condition the improved public reservations, four small triangular spaces have been highly improved and one partially improved. The asphalt roads and walks in Smithsonian and Judiciary parks have been extended, and repairs made to the asphalt walks in Lafayette, Franklin, Farragut, and Mount Vernon parks. The officer in charge invites attention to the propriety of separating the office rooms of the president from those of his home and submits suggestions for consideration. He also recommends the extension of the electric light system to include the Monument grounds, Lafayette, and Franklin squares. Attention is invited to the detailed report of the officer in charge, and to his estimates and recommendations for the fiscal year ending June 30, 1895. His estimates are as follows: For improvement and care of public buildings and grounds in charge of the Chief of Engineers... For compensation of persons employed on public buildings and grounds For contingent and incidental expenses of public buildings and grounds Salaries of employés One new engine complete in position, to replace the old en- $206, 821.40 61, 420.00 32,500.00 500.00 $9,060.00 650.00 3,600.00 13, 310.00 314, 551. 40 (See Appendix C C C.) NORTHERN AND NORTHWESTERN LAKES-SURVEYS-CORRECTING ENGRAVED PLATES-PRINTING AND ISSUING OF CHARTS. Surveys on the Great Lakes by engineer officers were made more than two generations ago. There are upon the files of this office maps of localities made by such officers in the years 1817, 1819, 1824, 1826, 1827, and many of later dates up to the present time. Up to 1841 these surveys were in connection with improvement of the various harbors, and of rivers tributary to the lakes. The needs of navigation demanding more than surveys of disconnected localities, ENG 9331 the " Survey of the Northern and Northwestern Lakes" as a connected whole was commenced under an appropriation made March 3, 1841, of $15,000 for a "hydrographic survey of the coasts of the Northern and Northwestern Lakes of the United States." This work was naturally assigned to the War Department, as its officers had theretofore been engaged in making local surveys and had charge of the works of improvement then in progress, and had been so engaged for a number of years; and Capt. W. G. Williams, then in charge of harbor improvements on Lake Erie, with station at Buffalo, was directed by a letter of May 17, 1841, to take charge of the survey and under the appropriation made March 3, previously. A few years thereafter the office was removed to Detroit, Mich., where it remained until the field work of the survey was completed in 1882, and that place has since remained the point for the distribution of the charts of the lakes. From 1841 the survey of the lakes was carried on under the following appropriations: The field work of the survey being completed, the office of the survey was closed in August, 1882, and the records transferred to this office. The printing of the final report was completed in November, 1882, Work in connection with the engraving and printing of the charts still remained, but of the appropriation of $12,000 last above mentioned, $2,382.32 was returned to the surplus fund of the Treasury. At that time the charts were perfected to the full needs of navigation under the then existing conditions. From the completion of the field work to the present time the following appropriations have been made, which have been applied to printing, electrotyping and issuing charts for the use of navigators: To June 30, 1893, the aggregate of $7,797.80 has been turned into the Treasury from the sale of charts. Up to February 20, 1890, charts to vessels navigating the Great Lakes were, by regulation, issued free, |
