in two gallons of water — or a wash of carbolic-acid 

 soap. But the first-named remedy is best. The stalls 

 and woodwork of the quarters occupied by the in 

 fested animals should also be treated. 



The Horn Fly is a recently imported insect that 

 often annoys cattle by sucking their blood and light- 

 ing upon their horns. The eggs are deposited in 

 freshly dropped cow-du^ig, in which the larvae 



develop, and pupate in the soil beneath. There are 

 four or five broods each season. During hot weather 

 the transformations of the insect — from egg to 

 imago — ^may be completed within two weeks. 



Remedies — Spray cattle twice a week, either 

 with kerosene emulsion, to which a little tobacco de- 

 coction has been added, or fish-oil, to which a little 

 carbolic acid has been added. Or rub on by means 

 of a brush or cloth. One stockman has had good 

 success by simply dampening the tips of the hairs with 

 a rag dipped in crude petroleum.
