Mr. A. P. Davis traveled duriug the 

 montli about three thousand miles. He 

 established river stations at several points 

 in Kansas and New Mexico and, later, 

 went to Colorado, where he made measure- 

 ments and rated meters. From California, 

 Montana, Idaho, Nevada, Nebraska and 

 other States and Territories come favorable 

 reports of the progress of the work in its 

 several branches. Reports from Washing- 

 ton and Wyoming are not so favorable. 



In the east Mr. C. C. Babb spent nearlj^ 

 the whole month on the Potomac, making- 

 measurements by which the discharge of the 

 stream can be computed for various heights 

 of water at the different gauging stations. 



In the oflBce, the preparation of a bulle- 

 tin, to be numbered 131, giving the reports 

 of field for the years 1893-'94, was com- 

 pleted. In this bulletin are inserted all 

 the available data concerning the various 

 river stations of the country and miscella- 

 neous information bearing upon the hydro- 

 graphic work. 



In the Division of Chemistry, under Profes- 

 sor F. W. Clarke, the number of routine 

 analyses completed and reported during the 

 month of May is 20, Dr. Hildebrand mak- 

 ing 6, Dr. Stokes making 5, and Mr. Stei- 

 ger making 10. In addition to this, some 

 special investigations were under way, and 

 these were well advanced. By Dr. Hille- 

 brand two papers were prepared for jour- 

 nal publication, one on chlorite, from Crip- 

 ple Creek, Colo., and the other on the esti- 

 mation of titanium. 



The work of the Division of Mining Statis- 

 tics, under Dr. D. T. Day, consisted in 

 preparations for the publication of the re- 

 port on mineral resources of the United 

 States for 1894. During the month the 

 statistics of production of coal, lead and 

 building stones, were given to the public, 

 through the press, and those on iron ores, 

 tin and the gold resources of the South 

 were in the printer's hands. 



In the Division of Topography nearly all the 

 parties have been placed in the field and 

 are at work in sections, as folloM^s: Atlantic 

 section. Central section, Pacific section, 

 Indian Territory section. The Indian Ter- 

 ritory work is a combined topographic and 

 land subdivisional survej^, and was speci- 

 ally authorized by Congress at its last ses- 

 sion. Work is in progress in 23 States and 

 Territories. 



In the General Editorial Division, the fol- 

 lowing manuscripts were read: — Reconnois- 

 sance of Gold Fields of Southern Appalach- 

 ians : G. F. Becker; for Part II., 16th Ann. 

 Rpt. Production of Iron-ores : J. Birkin- 

 bine, Bull. 131. Water Supply Data : F. 

 H. Newell. Text, Knoxville folio : Text, 

 Stevenson folio. Proofs were received from 

 the Public Printer of parts of the 15th and 

 16th Annual Reports and several Bulletins. 



In the Editorial Division of Geologic Maps 

 Mr. Willis edited the map of New York 

 State and worked on the Marysville and 

 Smartsville, Cal., and Stevenson, Ala., 

 sheets. Text for the Knoxville, Tenn., 

 Fredericksburg, Va.-Md., and Lassen Peak, 

 Cal., sheets was read in original, and after 

 reference to the authors sent to the press. 

 In the Editorial Division of Topograpihic Maps, 

 under Mr. Marcus Baker, attention was di- 

 rected largelj' to the revision and correction 

 of engraved atlas sheets which are about to 

 be pi-inted as the bases for geologic folios. 



In the Engraving Division the 31 topo- 

 graphic atlas sheets were in course of en- 

 graving. Of geologic folios in course of en- 

 graving there were 10, and besides, work 

 was continued on the 6-sheet map of New 

 York. 



In the printing department 5 geologic 

 folios were in press, viz.: Lassen Peak and 

 Marysville, Cal.; Staunton, Va.; Stevenson, 

 Ala., and Knoxville, Tenn. The Staunton 

 folio was completed. Editions of 11 topo- 

 graphic sheets were delivered from the 

 press.
