 numerous, few beavers are to be found at the present time. 



reports afford much valuable information on the life history and status 

 of the various species of game birds and mammals. Such items as 

 demanded immediate attention have been investigated, and much of 

 the information contained in the reports has been utilized. 



A book on the game birds of California, in preparation under the 

 auspices of the University of California Museum of Vetebrate Zoology, 

 under the joint authorship of Dr. Joseph Grinnell, the director of this 

 bureau, and Mr. T. I. Storer, is almost ready for the press. Although 

 the routine work of the bureau has precluded continuous participation 

 in the preparation of the manuscript during the past two years, all 

 available spare time has been given to a furtherance of the project.
