Adult beetle much enlarged. and delay putting out the main crop, so as to at- tract many of the striped beetles, stink-bugs and borers to the decoy strip. Extensive investigations have demonstrated that the cotton boll-weevil can be controlled only by cultural methods. Profitable crops of cotton can be grown in spite of the weevil by planting early- maturing varieties farther apart and earlier, by thorough cultivation, by plowing up and destroying all the old stalks in early autumn, and by a more liberal use of fertilizers—all these are " farm prac- ; By burning fruit-tree prunings before spring, the hibernating stage of several fruit pests, as plant-lice eggs and bud-moth larvae, may be de- stroyed. The application of a little quick-acting commercial fertilizer will sometimes stimulate a plant to overcome or outgrow the onslaught of its insect enemies; but when used in practicable or fertilizing quantities, these fertilizers will not kill the insects. It is an alluring thought that we may be able to develop insect-resisting varieties of many kinds of agricultural plants. The resistance of certain American native grape roots to the phylloxera plant-louse is proving to be the salvation of the grape industry in Europe. Promising eft'orts are now being made to develop a boll-weevil-resisting variety of cotton. Sometimes certain varieties of wheat seem to be resistant to the hessian fly. Much can be done around farmhouses to reduce the numbers of house-flies and mosquitos. Put the horse manure in tight sheds so that flies can not breed, or spread it on the fields every two or three days in summer. Drain off or fill in low places where water stands
