cent of the flies appearing about farm bnildings are bred, by 

 either hauling away each day or applying daily a mixture of 

 acid phosphate and kainite, or covering with dry earth, and 

 also by thoroughly caring for whatever garbage and other ad- 

 vantageous places for breeding there may be about the prem- 

 ises. A proper system of shading, that is, darkening rooms 

 when not in use, as well as proper screening, go a long way 

 towards keeping flies out of the stable and milk room. The 

 judicious use of fly paper, traps, sprays, etc., aids materially 

 in reducing the number of flies after they have appeared. 

 The greatest effort, however, should be made to prevent fly 

 breeding, and this should be done by using such means as are 

 effectual, and at the same time do not injure the fertilizing- 

 properties of the manure. 



We believe there is yet much to be learned in regard to the 

 means of preventing fly breeding, and it is hoped that this 

 contest and others that may follow will be useful in develop- 

 ing still better methods and devices. 



]Srature has apparently provided flies as the natural accom- 

 paniment of certain more or less disagreeable and unsanitary 

 conditions. Remove these conditions and the necessity for 

 flies no longer remains.
