88 MALARIA 



My dear Mr. Butler: 



Permit me to assure you of my hearty indorsement of your 

 crusade against malaria. Malarial fever is an absolutely prevent- 

 able disease and is one serious objection to your beautiful country. 

 No stagnant water, no mosquitoes ; no mosquitoes, no malaria. 

 Wishing you and your friends success in this movement, I am 



Yours sincerely, 

 (Signed) W. A. Briggs. 



Professor W. B. Herms, care H. E. Butler, Penryn, California. 

 We indorse most heartily your plan for eradication mosqui- 

 toes in Placer County. Will do anything in our power to assist.

Each district offered its own specific problems : at 

 Penryn, it was irrigation and mountain streams ; at 

 Oroville, dredger ponds, prospecting wells, water pipes, 

 and the Feather River; at Roseville, it was hard pan 

 and level country with poor natural drainage, also 

 lack of sewer system. 



The first thing in each case was to make a care- 

 ful survey of the territory to be protected, in order 

 to determine the nature of the problem ; this was 

 usually done with persons of influence concerned in 

 the respective communities. Next a field agent or 

 inspector was secured who was taken over the ground 

 and put in charge. House-to-house work was done 

 to secure intelligent cooperation, public lectures were 

 given, the school children listened to talks and saw 

 demonstrations, exhibits were placed in store win- 

 dows, newspapers were provided with material on the 

 subject, etc. At the same time proper corrections 

 were made in irrigation, pools were oiled, etc.
