Sixty thoHsaiul miles of trapline were run, tlie catcli averapin^ 

 one animal to each 64.5 miles of trapline. Seventy-six thousand five 

 hundred and i^ixty day-sets were made, or 82.5 per animal. The eosi 

 of trapping coyotes and bobcats was $11.64 per animal, or in time, 3.14 

 days. One bobcat was taken for every 400 miles of trapline and one 

 coyote for every 77.11 miles of trapline. Most of the coyotes, except in 

 San Benito County, were taken at elevations between 3000 and 6000 

 feet. Practically all of the bobcats were caught below the 5000 foot 

 level. In the experience of the trappers the area covered by a resident 

 coyote is considerably smaller than is commonly supposed. It is gen- 

 erally a circuit covered at intervals of several days, covering each day 

 an area of about five square miles. A female coyote, during the whelp- 

 ing time, ranges over a much smaller area. 



Eight additional trappers have been ]nit on ])redat()rv iMiiiiial woi-k 

 under the supervision of the experienced trappers who have been 

 cniploved i'or several years. To facilitate administration, tlie State has 

 been divided into five districts with a supervising trapper in charge of 

 each. The districts are as follows: 



Northeastern California district from the Sacraniento-Truokee Highway north to 



the Oregon line and west to the Sacramento river and Highway 99. 

 .\< I III I western Califdinia district from San Francisco Hay north to the Oregon line 



niid east to the Sacranwiito river and Highway 9!).

Ridge Koulc aTid west to San .Joaciuin river. 

 South Coast district from San Francisco Bay south to and including Ventura 



County and east to Grapevine on Ridge Route and San Joaquin river. 

 Soutliern California district. :ill of the southern i)art of the state from Tehachapi 



Mountains and \'cntuia County south to Mexican line. 



DEER STUDIES 



A study of fhc Koi-ky i\I()im1ain niiilc deer of northeastern Cali- 

 Fdi-iua lias liccii carried on continuously for the ])ast several years. This 

 sliidy includes adiial census Avork and is furnishing the Division with 

 definite inronnation as to the number, sex ratio, and condition of the 

 deer herd and of disease outbreaks and range conditions. A large por- 

 tion of the definite knowledge which we have of the mule deer has come 

 as a result of this study. 



During the last two years, fifteen count areas on the winter range 

 of llie mule deer have been mapped out and counts have been made
