Tlie roots not only go down, but spread widely in all direc- tions near the surface. Place one charge directly under the center of the stump on level land, and others 2 to 5 feet out under the anchor roots. It is no use to try to blast out big white pine stumps with single charges, even when fuse firing only is Before blasting. A stump that was loaded with a single charge, placed too shal- low at that. Oaks have the same general type of root development as white pine. The roots, however, are slimmer and hardly so long. To take out green stumps a heavy charge should be placed under the center and lighter charges out under the main roots. The most important fact about most oak stumps, however, is that the roots rot in a few seasons. After 5 to 10 years about all there is left of an oak stump is a bulk of trunk wood with short stubs. In this condition they can be blasted out and broken up with single charges very satisfactorily. White oak decays slowly. Oaks have a tend- ency to sprout. Chestnut is another semi-tap root variety with much the same character- istics as oaks, except that the roots de- cay more slowly, and sprouting is more marked. When chestnut stumps are left alone the centers rot out of the trunks, but the sprouts keep the roots alive, and the net fesult is that the whole thing is harder to remove after ten years than within a year after the original tree is cut. In some places oaks present the same condition. Maple is a great sprouter. These woods, however, are soft and more easily broken, hence come out with lighter charges as a us
