In the New England states, the woodlot may consist of almost pure stands of white pine, mixed spruce, pine, birch and the like, maple, oak and hickory; farther south it may consist of pure stands of scrub pine, pitch pine, black locust, or mixed hard-wood, yellow poplar, walnut, beech, chestnut; i n the south Atlantic and gulf states it may be loblolly or long-leaf pine, sweet gum or mixed hard- woods ; n 0 rt h of the gulf states it may he mixed hard-woods, with oak, hickory, lo- cust, box elder or Cottonwood pre- dominating; in the Rocky moun- tain region it may be pine, spruce, aspen or cotton- wood ; toward the Pacific coast, scrub oak, live oak, pine or redwood ; in the North- west it will consist of a different class of trees, growing under very different conditions from those found in any other section of country. Each tree and each section of the country has its peculiar class of insects, requiring special methods of control. It is readily seen to be impracticable to discuss in a short treatise even the more impor- tant insect enemies of the farmers' woodlots in all sections of the country. If we take one section, however, we may give some general information on the character and extent of the depredations by a few of the principal and more widely distributed enemies, and methods for their control. Enemies of a special section. In the section east of the Mississippi river and north of the gulf states, the average insect losses affecting the medium- to large-sized hard-wood trees of the woodlot and small forests evidently equal, or even surpass, the average losses to the same class of timber by forest fires. The hickory bark-beetle has killed a large percentage of the hickory; the black locust has been so b
