 They pointed out a definite and feasible program of tick control 

 by dipping and otherwise freeing domestic animals of ticks. How- 

 ever, the work of that season did not indicate conclusively just 

 what solution to dip with, how often to diji, or how long to keep 

 it up. We undertook to secure information on these points in the 

 spring 01 1911. It was nearing- the close of the Bureau's fiscal 

 year and thev could not furnish us the funds required for the con- 

 struction of the necessary dipping vat and yards and after an un- 

 successful attempt to get the sum through the State Board of 

 Health, to which a special appropriation for spotted fever investiga- 

 tions had been made, we accepted a fund made up by voluntary 

 contributions by chambers of commerce and individuals in the Val- 

 ley. At this point it was learned that the Public Health and Ma- 

 rine Hospital Service at Washington, ]). C. was about to send 

 representatives into the State under the auspices of the State Bo?rd 

 of Health for the puri)Ose of undertaking the extermination of ticks 

 in the spotted fever district. A conference was held in \Vashingion 

 between the chief of the Bureau of Entomology and the head of the 

 Public Health and Marine Hospital Service at which it wr^s learned 

 that the latter saw no necessity whatever for co-operative work. 

 The situation led to the withdrawal of the Bureau of Entomclopy 

 and the Bureau of Biological Survey. Instead of having two bu- 

 reaus of the Department of Agrirulture working on this problem in 

 Montana on their own funfls c^nd in their special lines we now 

 have the Public Health and Marine-Hospital Servdce working on 

 ticks on funds furnished by the State.
