Second-Growth Stumps There is often directly under a second-growth stump the de-cayed remains of the original stump; this is soft, and the force ofthe explosive when placed on it seems to merely scatter this deadwood and has no marked effect upon the stump above. To overcomethis difficulty, it is a good plan to dig under the stump and place agood-sized flat stone between the roots, leaving only room on top ofthe stone for the dynamite. Damp clay should then be firmly packedaround the dynamite. This gives sufficient resistance to the explosiveto enable it to lift out the stump. Red Cross 40% Extra Dynamiteshould be used. See pages 11 to 16 for proper methods of priming,charging, tamping and firing. FELLING TREES Occasionally when clearing land of growing timber, it is of ad-vantage to blast out the entire tree and saw off the root afterwards. 40. SPLITTING STUMPS AND LOGS The process here is exactly the same as in stump blasting, but a littlemore dynamite is required to bring out the tree, roots and all, than toblast the stump after the tree has been cut. The blast lifts the treestraight up a foot or two; then it falls, generally with the wind. Seepages 1 1 to 15 for proper methods of priming, charging, tamping andfiring. SPLITTING STUMPS AND LOGS When stumps, particularly large ones, are blasted out whole ornearly so, it is usually necessary to split them up so that they can beconveniently handled or burned. This can be readily accomplishedwith dynamite; only a small quantity of explosives being required ifthe charge is properly tamped in auger holes bored part way throughthe stump. In the South the pine stumps are very large producers of tur-pentine and by-products. Nothing is
