Vol. X] EVERM ANN— DIRECTOR'S REPORT FOR 1920 147 



Two new metal book stacks were erected in the basement library room, 

 furnishing shelving space for 2400 volumes. This additional shelving 

 has made it possible to relieve and rearrange some overcrowded subjects, 

 thus adding materially to the orderly arrangement of the books stored in 

 the basement room. 



Work in the library department has, as in the two previous years, been 

 in the hands of Miss McClellan and Mrs. Van Duzee, and to the faithful 

 and efficient performance of the duties devolving upon these two is due 

 the progress made in this department of the Academy's activities. 



The collating, classification and cataloging has been completed in the 

 series of publications of scientific societies and institutions issued in for- 

 eign languages, and in the subjects of engineering, chemistry, geography, 

 mathematics, medicine, mining, ethnology and archaeology and work on 

 several other subjects is nearing completion. All current accessions also 

 have been cataloged and placed on the shelves promptly as received. Use 

 of the library by the Academy membership has shown a gratifying in- 

 crease and it is hoped that with the improvement of the catalogue and 

 the more systematic arrangement of the books on the shelves will come 

 an increasing and more effective use of the books we have, both by the 

 museum staff and the Academy membership in general. 



E. P. Van Duzee, Assistant Librarian. 



Department of Mammalogy 



As heretofore, this department has been coordinated with that of Or- 

 nithology, and what field work was accomplished was done incidentally 

 with that in the latter department. 



A succession of dry seasons in northern California made the collecting 

 of small rodents a difficult matter on account of their scarcity, but a con- 

 siderable number was obtained. 



The Academy's collection of mammals had never been completely 

 checked up, labelled, or entered upon the accession register, but this work 

 is now nearly finished. Many of the large skins were only salted or dried, 

 but the necessity for the better preservation of these very valuable speci- 

 mens became so evident that Mr. H. W. Vogelsang was employed to tan 

 them. The larger proportion of these have been so treated with most 

 satisfactory results. 



These skins have heretofore been stored in the ordinary metal cases in 

 use for the smaller mammals, and therefore not readily accessible. It 

 was decided to build a hide room in which to hang them when tanned. 

 For this purpose a space has been enclosed in the vacant store room at 

 the northwest corner of the Mammal Hall, in which all hides will be 

 easily accessible for examination. 



Gifts to the department have been made by Messrs. F. S. Townsley, 

 J. R. Slevin, Chas. Budd, Geo. A. Bailey, W. C. Hackmeier, Dr. Saxton 

 Pope, the Golden Gate Park authorities, and others, as shown in the List 

 of Accessions. 



Joseph Mailliard, Curator.
