90 MALARIA 



In December, 1909, a few public-spirited citizens of 

 Penryn, learning that malaria is a disease which can 

 be eradicated or largely controlled by proper measures, 

 got together, organized a campaign, and called in the 

 assistance of the scientists of the University of Cali- 

 fornia. William B. Herms, Assistant Professor of 

 Entomology in the College of Agriculture at the Uni- 

 versity, took the campaign under his personal super- 

 vision, and its success is largely due to his ability and 

 energy. ■ 



The work done at Penryn is especially worthy of 

 note because of the fact that it is the first of its kind 

 in the state, and is typical of the gradual awakening 

 of the public to the facts of the recent marvelous 

 increase in our knowledge of the control and preven- 

 tion of disease. While many other communities in 

 the central region of California either are indifferent 

 to the presence of malaria, or deny its existence for 

 fear of hurting business, Penryn has been the first 

 to look the facts squarely in the face, and then intelli- 

 gently set about remedying the conditions. Two other 

 communities, Oroville and Bakersfield, followed suit 

 in 1910, and from the inquiries sent to the State Board 

 of Health during the past year it is probable that 

 many more will start campaigns in 191 1. 



In the following pages will be found a brief descrip- 

 tion of the campaign, with methods, costs, and other 

 data of interest.
