TWENTY-NINTH BIENNIAL REPORT. 87 



During the first six months of this year, twenty-five loans were made 

 in addition to the use of films at scheduled lectures. 



ROUTINE OFFICE WORK. 



Through the years this bureau has had charge of the issuance of 

 scientific collector's permits. In December of each year, the reports of 

 150 collectors in the state are filed and new permits issued. In most 

 instances, scientific collector's permits are limited to a small number 

 of birds and their issuance is based largely on the actual scientific or 

 educational use to be made of the specimens. 



A compilation of hunting accidents has been made and published 

 annually. 



Attention has been given the care and filing of sportsmen's maga- 

 z;ines and other publications. All such publications are arranged in 

 chronological order and are available for reference. Likewise, a large 

 collection of photographs has been filed and indexed. The complete 

 card index record of the Commission's publications is up to date. 



PUBLICITY. 



For some time the Commission has needed wider publicity as to its 

 accomplishments and plans. This was finally attained in the spring of 

 1926 and a separate Bureau of Publicity was established relieving the 

 old ])ureau of the newspaper publicity. Previous to that time, numer- 

 ous items on activities of the Commission and on conservation were 

 prepared and mailed to the newspapers. A check showed that these 

 items were widely used by newspapers throughout the state. 



Puldicity was further attained through lectures, the State Fair 

 exhibit, motion pictures, radio broadcasting, loan of photographs and 

 cuts, and through numerous conferences. 



RESEARCH AND INVESTIGATIONS. 



Progress has been made on the stomach examination of ducks, look- 

 ing toward a final report on the food of ducks in California; however, 

 this important pro.iect is still incomplete. A number of miscellaneous 

 stomach examinations of birds have been made and the data filed, like- 

 wise, a number of identifications have been made for various persons 

 and reports submitted. 



During the summer of 1924 special study of the relation of birds and 

 animals to the the foot and mouth disease was made and a report 

 written. Also, the conditions oil Lower Klamath Lake were investigated 

 at the request of the United States Biological Survey and a full report 

 rendered. 



Several post-mortems made on ducks djang from a peculiar disease 

 in the Sacramento Valley showed the usual signs of alkali poisoning. 

 Splendid help from the veterinary department of the University of Cali- 

 fornia is acknowledged. A number of quail reported as having been 

 poisoned were sent to a chemist and an analysis was made. The results 

 were negative. 



In the fall of 1925 quail poisoning experiments conducted by the 

 Associated Sportsmen of California were watched with resultant profit.
