Show 37 abont November 25. The California parties will reach Caliente, the present terminus of the Southern Pacific Railroad, about the same date. They will be disbanded, the animals transferred, and the articles of public property put in store. Special operations for the month of October.- Regular office- work will be continued as usual. The publication of volumes III and V will be pushed with all possible vigor. The manuscript for volumes II and IV wiW be sent to the printer as soon as he is ready for it. The manuscript of the Catalogueof Mean Declinations of about2,000Stars, now being prepared by Professor Safford, will be finished. Lieutenant Berglaud will be directed to take a temporary office at Los Angeles, and complete observations necessary to bring about a complete connection between the base measured by this survey during the past season and that measured by the Coast Survey in 1854 near Los Angeles, and certain other observations necessary to complete belts of triangulation, which, if successfully concluded, will reach from the coast near Los Angeles, in a triple tier, northeastward to about the one hundred and sixteenth meridian of longitude west from Greenwich. These belts of triangles form the basis of a system that can be developed over at least all of the southern half of California, a portion of Southwestern Nevada, and all of Western Arizona. From the preliminary plots and field- work, profiles and other sections and special plots will be made, and a report of the examination of the Colorado River at the mouth of the Virgin, near Camp Mohave, will be prepared and forwarded to this office without delay. When Lieutenant Bergland submits this preliminary report, it can more nearly be . determined as to the practicability of reorganizing his party and dispatching it to the lower part of the Colorado River, to continue its operations during the winter months, in advance of which the matter will be submitted to the Chief of Engineers for further instructions, if such be considered necessary. It is hoped that funds from the appropriation for explorations and surveys, for the present fiscal year, may be available, sufficient in amount to cover the expense of a winter campaign of about four months; if not, further appropriation must be asked. The several parties of the California and Colorado sections will prosecute this work during the month in the areas assigned to them. Respectfully submitted. GEORGE M. WHEELER, Lieutenant of Engineers, in charge. OCTOBER 1,1875. APPENDIX A. EXECUTIVE BEPORT OP LIEUTENANT WILLIAM L.
