 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 

 Avhat solution to dip with, how often to dip, or how long to keep 

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

 spririg ui 1911. It was nearing the close of the Bureau's fiscal 

 year and they 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 'ever investiga- 

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

 contributions by chambers of commerce and individuals in the \'al- 

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

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

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

 of Health for the purpose of undertaking the extermination of ticks 

 in the spotted fever district. A conference was held in Washingion 

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

 ]^i,l:)lic Health and Alarine Hospital Service at which it wr^s learned 

 "^hat the latter saw no necessity whatever for co-operative work, 

 '.rhe situation led to the withdrawal of the Bureau of Entomclopy 

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

 reaus of the Department of Agri^mlture working on this prolilem in 

 Montana on their own fun -Is and in their special lines we no\v 

 have the Public Health and Ivlarine-Hospital Service working on 

 ticks on funds furnished by the State.
