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-ng, 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.
