illegible Sept. 11, 1912 Mr. E. T. Parsons, 1 Mosswood Road, Berkeley, Calif. My dear. Mr. Parsons:- Mr. Adelbert
Cronise has enclosed to me your letter of Sept, 4th and asked me to answer your questions. First, as to the outbreaks of
typhoid occurring as a result of the polution of the Hemlock water supply: Ten years ago last March when the ground about
the Henlook hills was well covered with snow, a sudden rise in the air temperature occurred and the snow melted and rapidly
ran into the lake. The water at that time was found to contain some colon bacilli, but no rise in typhoid took place. Nevertheless,
at that time the people were warned to boil the water. Two years ago this present month, we found that the water mains in
the north-western section of the city, with a population of about 50,000 people, the water had become contaminated with the
river water. Upon examination it was found that someone had made a connection between the pipes of the Holley system (river
water) and the Hemlock system, and that this poluted the Hemlock water. A marked rise in typhoid took place within the next
month or two, some of which was no doubt due to this carelessness. I am sending to you a copy of the laws and ordinances
covering the water supply of Hemlock Lake. The city now owns most of thebed of the lake as well as 80 illegible of the shore
