Insects affecting the cotton plant . on the growing parts can not be easily an ordinary knapsack pump a field may be gone over rapidlyand the volunteer cotton thoroughly treated, the nozzle being directedat each growing tip. The first application should be made as soonas the volunteer sprouts, and perhaps repeated two or three timeswithin as many weeks. As ordinarily cultivated, the number of vol-unteer plants is small and the time required for the thorough sprayingof such plants will not be great. A strong solution should be applied,viz, 1 pound of the poison to 50 gallons of water, because no harm willbe done if the volunteer plants are ultimately killed by the poison. The practicability of this method has been demonstrated, but it hasbeen abundantly shown that the very best system of control of theweevil is in a system of cultivation of cotton, to be later described,which will prevent all possibility of volunteer growth whatever. Thepoisoning and the other palliative measures relative to volunteer growths. 22 are given, therefore, merely as a means of correcting an evil which mayresult if the cultural system referred to has been neglected. Theseremarks apply, for instance, to the trap system, which we have hithertorecommended among others. This consists of attracting the earliestbeetles to a few cotton plants left at convenient points and protectedfrom winter killing by forced watering, so that they will branch outand acquire buds often in advance of volunteer cotton. From thesethe beetles may be collected by hand when they are attracted to themby the first warm days, or, preferably, these plants may be poisoned,as already suggested. The fact that the spring generation develops only upon volunteercotton has suggested the possibility that the insect will not spreadbeyond the region where volunteer cotton will grow in spring, butunfortunately this possibility is by no means absolutely to be reliedupon. Nevertheless, the destruction of such volunteer pl
