[N.S. Vol. XIX. No. 478. 



this work completing the survey of the re- 

 serve; also 154 miles of the boundaries of the 

 Black Mesa Forest Reserve and 12 miles of 

 those of the Mount Graham Forest Eeserve 

 of Arizona were surveyed and similarly 

 marked. In the office 97 atlas sheets were 

 completed and the entire revision and redraft- 

 ing of the large topographic wall map of the 

 United States was commenced. 



The division of geography and forestry was 

 instrumental in making an agreement be- 

 tween the representatives of the farming in- 

 dustry and the sheep industry in Utah, to the 

 effect that the entire mountain region of 

 Utah, which constitutes at present the sum- 

 mer range for sheep, be reserved; that in such 

 portions of these reserves as contributed to 

 the water supply of the agricultural settle- 

 ments sheep grazing be prohibited; that the 

 remaining portions of the reserves be allotted 

 to the various sheep owners for extended 

 periods, and that the number of sheep to be 

 grazed upon a unit of area be restricted far 

 below the present number. About 7,500 

 square miles of forest reserves were examined 

 during the season. The appropriation for 

 this work amounted to $130,000. 



The funds available for the work of the 

 division of hydrography were doubled by 

 the appropriation act of June 28, 1902, and 

 the operations under the reclamation law 

 were entrusted to the officials of this divi- 

 sion. As a consequence, it became neces- 

 sary, for administrative purposes, to create a 

 separate branch of the Geological Survey. 

 This is known as the hydrographic branch, and 

 includes the work of the division of hydrog- 

 raphy and also that of the reclamation ser- 

 vice, organized to carry on the surveys and 

 examinations authorized by the reclamation 

 law. The proceeds of the sale of public lands 

 in the western states and territories, which 

 were set aside to create a fund for this pur- 

 pose, amount to between $3,000,000 and 

 $4,000,000 a year. Preliminary investiga- 

 tions made to show the extent to which the 

 arid lands can be reclaimed by irrigation have 

 been carried on by the Geological Survey for 

 many years. At the beginning of the fiscal 

 year the various engineers who had previously 



been engaged in these investigations were pro- 

 vided with added facilities for extending the 

 work and carrying on to construction the pro- 

 jects that were considered feasible. Surveys 

 and examinations were made in the states of 

 Arizona, California, Colorado, Idaho, Kansas, 

 Montana, Nebraska, Nevada, New Mexico, 

 North Dakota, Oklahoma, Oregon, South 

 Dakota, Utah, Washington and Wyoming. 



A division of hydrology has also been added 

 . to the hydrographic branch, the purpose of 

 which is to study geologic conditions govern- 

 ing the occurrence of underground waters. 

 Another feature of this branch is the division 

 of hydro-economics, of which the chief raison 

 d'etre is the investigation of the equality of 

 water and its effect on various industries. 



Many interesting details are also given in 

 this report concerning the work of the publi- 

 cation and administrative branches of the 

 survey. Significant of the amoimt of matter 

 published by the survey is the statement that 

 20,756 pages of manuscript were edited dur- 

 ing the year and 257 atlas sheets and special 

 maps were engraved.

EMIL ALEXAWDER DE SCEWEINITZ. 

 The Medical and Dental Departments of 

 Columbian University have passed the follow- 

 ing resolutions in memory of the late Dr. de 

 Schweinitz : 



A great calamity has befallen the medical and 

 dental departments of the Columbian University 

 in the death of Dr. Emil A. de Schweinitz, pro- 

 fessor of chemistry and toxicology and dean of 

 the medical faculty. 



Dr. de Schweinitz became professor of chem- 

 istry in 1893, and four years thereafter (1897) 

 he was appointed dean of the medical faculty. 

 He filled both positions with marked ability until 

 his death on February 15, 1904. 



Not only was he admired and beloved by the 

 students for his ability as a skillful teacher, both 

 in the lecture room and laboratory, but his 

 gentle method and kindly interest in their wel- 

 fare won for him their devout regard and un- 

 limited esteem.
