spring repairs over the 30 miles of permanent road previously constructed, and for betterments and temporary repairs to some 40 miles of the original unimproved roads. During the fiscal year ending June 30, 1889, the sum of $130,000 can be profitably expended. With this it is proposed to complete the circuit of main road from Mammoth Hot Springs, via Upper Geyser Basin, Shoshone and Yellowstone lakes, the falls and Yancy's, some 145 miles, of which about 40 miles were completed July 1, 1887; to repair existing roads; to purchase a portable saw-mill and rock-crusher, and to build a warehouse for tools and supplies, a small office, a stable, and a house for the overseer in summer and the watchman in winter. The estimated amount required for the entire and permanent completion of the roads and bridges, in accordance with the approved and adopted project, is $250,000. Amount appropriated by act approved August 4, 1886.... $20,000.00 July 1, 1887, amount expended during fiscal year, exclusive of liabilities outstanding July 1, 1886 ... 20,000.00 Amount (estimated) required for completion of existing projects 250,000.00 Amount that can be profitably expended in fiscal year ending June 30, 1889 130,000.00 Total expended to July 1, 1887. 89, 779.42 (See Appendix A A A.) ANNUAL WATER-LEVELS OF THE NORTHERN AND LAKES. NORTHWESTERN Tables and diagrams showing the monthly means of water-levels from July 1, 1882, to June 30, 1887, at Charlotte and Sackett's Harbor, Lake Ontario; Erie and Cleveland, Lake Erie; Milwaukee, Lake Michigan; Escanaba, Green Bay; Sand Beach, Lake Huron (from September, 1874); Marquette, Lake Superior; and Sault Ste. Marie (from Decem ber, 1881), being in continuation of those published in the Annual Report of the Chief of Engineers for 1882, will be found in Appendix P P. PRINTING AND DISTRIBUTION OF CHARTS OF THE NORTHERN AND NORTHWESTERN LAKES. Under the supervision of this office the following engraved copperplate of charts of the northern and northwestern lakes has been electrotyped: Lake Huron. The following charts have been photolithographed and an edition printed: Detail charts of the St. Lawrence River, Nos. 7, 8, 9, 10, and 11; scale, Toboo. Corrections in aids to navigation have been made on each of the fol lowing engraved chart plates: Lake Ontario; Lake Ontario coast charts, Nos. 1, 3, 4, and 5; Lake Erie; Lake Erie coast charts, Nos. 3, 4, 5, 6, and 7; Lake St. Clair; Detroit River; Straits of Mackinac; Lake Huron; Sand Beach Harbor of Refuge, Lake Huron; south end of Lake Huron; north end of Lake Michigan; south end of Lake Michigan; northeast end of Lake Michigan, including Grand and Little Traverse bays; south end of Green Bay; Lake Michigan coast charts, Nos. 1, 4, 5, and 6; Lake Superior charts, Nos. 1, 2, and 3; Isle Royale, Lake Superior; River St. Marie, No. 1. During the year 4,995 charts were issued under the supervision of Lieut. Col. O. M. Poe, Corps of Engineers, 1,536 of which were sold at 30 cents each, and the amount, $460.80, turned into the Treasury. Owing to changes in channels, the discovery of previously unknown dangers, and the extension of works of river and harbor improvement, many of the charts require additions and corrections in order to render them of the greatest service. In some cases limited surveys will be required to obtain the requisite data. Considering the extensive use made of the charts and their recognized value to the lake marine, it is recommended that the sum of $10,000 be annually appropriated for the purpose of making the necessary surveys and for correcting the engraved plates, in addition to the amount appropriated for electrotyping the plates and for chart printing. Amount appropriated by act of August 4, 1886..... Amount appropriated by act of March 3, 1887... $2,000.00 1,973.50 2,000,00 $10,000.00 3,000.00 13,000.00 (See Appendix B B B.)

A new map of the departments of California and the Columbia has been completed, with the exception of some minor additions. (See Appendix D D D.) Lieut. John Biddle, engineer officer Department of Dakota, reports the survey of the military reservation at Fort Buford, Dak., and the laying out of a new target range at Fort Snelling, Minn. In addition to his duties as engineer officer, Lieutenant Biddle assisted the commissioners appointed by the Department of the Interior in allotting lands in severalty to the Crow Indians on their reservation in Montana. Plats of all the military posts in the department have been revised, and descriptions of military and Indian reservations, with such itineraries as were deemed useful, have been prepared and published in a general order at headquarters Department of Dakota.
