THE PENRYN CRUSADE 101 



and it has not been possible to keep persons affected 

 with malaria screened during sleep, thus preventing the 

 infection of such Anopheles as may have escaped the 

 vigilance of the Field Agent, which may in turn, after 

 a period of ten or twelve days, inoculate another 

 person. 



As to the general conditions with regard to both 

 adults and children, Dr. 0. L. Barton of Loomis, 

 whose practice includes practically all cases in Penryn 

 and its vicinity, personally told me, and authorized 

 me to state in his name, that there has been very much 

 less malaria this year (1910) than last year (1909) and 

 that a large majority of the cases this year have been 

 chronic forms, manifesting themselves principally as 

 malarial neuralgia. He further stated that in his 

 opinion, even if it were not a fact that malaria is trans- 

 mitted only by Anopheline mosquitoes, the personal 

 comfort of a summer free from mosquitoes and their 

 attendant irritating bites is well worth the cost of the 

 control, and that next year Loomis 1 would certainly 

 have an efficient control campaign throughout the entire 

 year. He expressed himself as being very much in 

 favor of cooperation among the communities in Placer 

 County affected with malaria, especially on the basis 

 of the formation of a Sanitary District. 



Conclusion. — ■ It has been demonstrated that malaria 

 can be and has been controlled in Penryn through 

 the destruction of the Anopheline mosquito, which 



1 Loomis did not carry on a crusade in 191 1.
