There- fore for the treat- ment of evergreens spraying is a neces- sity. The methods of controlling shade- tree pests in cities and towns, as out- lined in Farmers' Bulletin No. 99," on pages 25-29, are in part applicable to this species. This bulletin should be read by persons who have experienced trouble from the depredations of the bagworm. Collecting the hags. â ^ One of the most important remedies consists in gath- ering the bags with the contained insect by hand and either burning them or preserving them to lib- erate the useful parasites which have been previ- ously mentioned. This work may be facilitated by thp use of a 12-foot pole pruner or similar appliance, and can be intrusted to those ordinarily unemplo3'ed, such as children and aged persons. Where the trees are very tall it will be necessary to use a long ladder. For best results the cooperation of neighbors who are troubled with the same pest should be secured. a This publication may be had gratis on application to the Department of Agriculture. [Cir. 97].
