evidence of these facts. From a letter received from 

 Dr. C. L. Wellman, dated November 3, 1910, the 

 following is quoted : — 



"From the fifteenth of August to the first of September we 

 had forty-eight (48) cases of Malaria who were admitted to the 

 hospital. During the month of September sixty-nine (69) were 

 admitted and seventy-two (72) in October. Of course this does 

 not include the cases which were not treated in the hospital but 

 were prescribed for in quarters. Of these we have no record. I 

 think a safe estimate of the prevalence of Malaria among- the 

 workmen would be 25 per cent. It seems to be fairly evenly 

 distributed between Rocklin and Clipper Gap."
