Show IV. are contained iu the, report, which also includes a discussion of practicability of the diversion of this stream. Of the six quarto volumes authorized to be published by the aot of June 3, 1874, as amended by the act approved February 15,1875, two volumes, namely, III ( Geology) and V ( Zoology) have been printed, as well as part 1 of volume IV, ( invertebrate Fossils.) The manuscript of volume II ( Astronomy and Meteorology, including Barometric Altitudes) and the second part of volume IV is ready, while that for volumes VI ( Botany) and VII ( Ethnology, Philology, and Ruins) is in an advanced stage of preparation, as well as volume I, ( Geographical Report.) The manuscript of The Declination of 2,018 Stars, by Prof. T. H. Safford, has also been completed. Seven published sheets have been added to the topographical atlas, and others are completed and in various stages of progress. Six geological- atlas sheets have befen published, and three are now ready for, or in the hands of, the engraver. The results determined by the several scientists connected with the investigation of the subjects of natural history are, in addition to the results primarily intended to exhibit the operations of the survey, namely, the preparation of a detailed map of the sections entered, with a description and delineation, so far as practicable, of their natural resources, and showing the distribution of the arable and arid portions, the former divisible into those sections which are susceptible of cultivation, those in which irrigation can be had, and into mining, timber, and grazing sections, the latter entirely valueless at the present or any near prospective date, for occupation or use in any remunerative capacity from such industry that is likely to venture within its borders. The topographical maps, that have been prepared upon scales as follows : 1 inch to 8 miles, 1 inch to 4 miles, and 1 inch to 2 miles- forming the principal results of the survey, furnish information of immediate value to the different branches of the military service, and incidentally to the other departments of the Government and to the public. The regular progress of this important work without interruption, it is believed, will commend itself to the attention of Congress, and it is earnestly recommended. The amounts required to continue the survey, as estimated by Lieutenant Wheeler, are recommended, viz: For continuing geographical surveys of the territory of the United States west of the 100th meridian $ 95,000 0O For preparing and engraving plates and atlas sheets accompanying reports upon geographical surveys west of the 100th meridian 25,000 00 His annual report, with appendixes and estimates, is appended.
