Most of the information gathered has been collated, and will appear in volume I of the Survey Reports. • ECONOMIC BOTANY AND AGRICULTURE. The agricultural resources of the Far West is a question increasing in interest with each succeeding year, and is one of vital importance to the Government aud country at large. While the main objects of the survey do not admit of elaborate investigations upon this and other subjects of general interest, it has nevertheless been attempted to push inquiry as far as time and facilities would allow. Accordingly, Doctors Rothrock and Loew submit reports < see Appendixes II 1 and H 2) upon the subject; the former in a relative way in connection with his more specific field, ( botany,) adverting to the general topography of the region traversed, its climatology, the relation of forest plants and timber to present and prospective wauts, the probable increase in agricultural areas under cultivation aud irrigation, and a system of tree- culture, the sanitary conditions of the country as influencing immigration, & c. Dr. Loew treats more especially of the capacities of the soil, its constituent elements, the character aud influeuce of climate, irrigation, & c, with analyses aud comparative tables. He also. treats upon this subject incidentally in his report upon mineralogy, ( see Appendix 6 S.) ZOOLOGY AND BOTANY. Collections in these branches have been made during the year by Acting Assistant Surgeons H. C. Yarrow and J. T. Rothrock, United States Army, aud H. W. Heushaw and Charles B. Aiken, ornithologists. Dr. Yarrow submits a general itinerary, and Assistants Henshaw and Aiken report upon the collections in ornithology. An " Annotated List of the Birds of Arizona," by Mr. H. W. Henshaw, is introduced, ( see Appendixes 11 and 12.) With small additional expense no little increase has been made in the lots of collections, heretofore large, that have been gathered from year to year. ETHNOLOGY, PHILOLOGY, AND RUINS. Ethnological material characteristic of present and extinct tribes has been gathered, and facts of note recorded by several members of the expedition since the season of 1872. Belies of stone, flint, & c, have, during the present season, been discovered along the coast near Santa Barbara'that rival all others yet found by parties of the survey. A party in charge of Acting Assistant Surgeon H. C. Yarrow, United Slates Army, assisted by Acting Assistant Surgeon J. T. Rothrock, United States Army, H. W. Henshaw, aud several laborers, has beeu engaged for some weeks in their excavation. Selections from the multitude of specimens will be forwarded to Washington ; meanwhile information of shell- mounds and other iudications of ancient buried remains of a people of which history contributes no trace |
