As a Cattle Pest. — In a most useful and interestinfj paper on the 

 stable fly, as a live stock pest, Bishopp ' regards this fly as very impor- 

 tant. Injury is brought about in various ways, e.g. worry, due to the 

 attacks of myriads of flies; loss of blood ; lessening of the milk supply 

 from 40 to GO per cent ; loss of flesh ; bringing on attacks of acute 

 Texas fever if the cattle are already parasitized ; etc.

There is little doubt that the fly is a great factor in disease transmission. 

 In many cases swollen and stiff joints of both horses and cattle are caused from 

 standing in water where they seek protection from flits. 



Numerous instances are reported of animals becoming frantic from the painful 

 stings and receiving serious injuries from running into barbed wire fences.
