flies and other insects; and to provide for the assessment, levy, col- 

 lection and disbursement of taxes therein. It provides that such tax 

 must not be greater than sufficient to raise the amount estimated by 

 the board of trustees of the district, appointed by the county super- 

 visors, and must not be in excess of ten cents on each one hundred 

 dollars of taxable property in such district. 



The first district to be organized under the new law was the San 

 Mateo District, the second being Marin County District No. 1, both 

 involving salt marsh areas. These two districts are now in charge of 

 Mr. N. ]M. Stover, a graduate of the University of California. A 

 second salt marsh district has been organized in San Mateo County, 

 known as the Pulgas District. The first inland district to be organ- 

 ized involving fresh water mosquitoes of the malaria-bearing type was 

 at Bakersfield, — the Doctor Morris District. Oroville (Butte County) 

 has a well organized district while the Los Molinos District (Tehama 

 County) is ready for operation and Riverside (Riverside County) and 

 Yolo County are now in process of formation. 



The act makes it possible to include both incorporated and unin- 

 <}orporated territory or portions of both in the same district, thus 

 protecting communities which draw their supply of mosquitoes very 

 largely from the outskirts which may be outside the corporate limits. 



Fourteen species of mosquitoes for California were listed by Quayle^ 

 in 1906, viz.: Anopheles punctipennis Say, Anopheles maciilipeyii\is 

 Meig., Anopheles franciscanus McCr., Psorophora ciliata Fabr., Ochler- 

 otatus varipalpus Coq., Ochlerotatus lativittatus Coq., Ochlerotatus syl-

 territans Walk., Culex pipiens L., Theobaldia annulatus Schran., Theo- 

 haldia incidens Thom., and Culiseta consobrina Desv. At the pres-
