This fly lays its eggs in the freshdroppings of cows, and these hatchinto tiny whitish maggots, whichlive in the dung three or four then burrow a half inch orso into the ground beneath the ma-nure, and remain quiet for aboutfive days, at the end of which theyg. horn fly.

Or sprinklekerosene oil or emulsion on all freshdroppings. Fresh powdered
