REPORT OP THE FISH AND GAME COMMISSION. 89 



been seeping out of the ^ards for several years past. I have been unable 

 to get figures on the actual amount of oil thus recovered but it must be 

 considerable. 



There is still some complaint about "tankers" pumping ballast out- 

 side the entrance of San Luis Bay but this practice has evidently ceased 

 in the vicinity of the Farallones and San Francisco lightship. 



A concrete separator has been constructed by the Union Oil Com- 

 pany at Avila to recover the oil leakage from the "topping" plant 

 and the Pacific Gas and Electric Company have done likewise at Vallejo 

 to retain lampblack. 



Prohibition has, temporarily at least, aided the cause by eliminating 

 the winery and distillery, both of which were sources of pollution par- 

 ticularly deadly to fish. 



There are treble the number of small concerns using fuel oil than 

 existed prior to 1918, all of which require frequent inspection. Small 

 leaks may amount to nothing individually but the aggregate may run 

 into barrels. 



Respectfully submitted.

 In Charge, Department of Water Pollution.

 of California. 



Sirs: We herewith submit a report for the San Francisco District 

 covering the period from July 1, 1918 to June 30, 1920. 



PERSONNEL. 



The Fish and Game Commission has been particularly fortunate in 

 retaining practically all of its employees during the strenuous times 

 of the past several years. Although many employees obeyed the call 

 to arms, they all returned safely at the close of the war. The higher 

 wages paid in other lines of work proved attractive to only a few. For 

 the most part their interest and loyalty held them even though it meant 

 financial loss. 



GAME CONDITIONS. 



On account of the dry season the duck and goose shooting has not 



been as good as usual. The only part of the state where waterfowl were 



found in normal numbers was the Sacramento Valley. In the San 



Joaquin Valley there was practically no loafing water and for the most
