. Better farming with Atlas farm powder, the safest explosive, the original farm powder. Explosives in agriculture. Better Stump Removing frozen so long as the crust is not too thick for easy making of holes. Two or 3 inches does not greatly hinder opera- tions. The roots seem to come free from the ground and the stumps break up better under such conditions than in summer. Atlas Farm Powder is par- ticularly satisfactory for this cold weather blasting, since it requires little or no thawing. Since fall and winter, or early spring, often are the times when there is least other farm work to do,

Atlas Farm Powder is par- ticularly satisfactory for this cold weather blasting, since it requires little or no thawing. Since fall and winter, or early spring, often are the times when there is least other farm work to do, stump removing in many instances can be done then to Typical tap-root stumps, with the dirt washed away. To ;,, , ,,, m out the charge must be located against the big root, four or five feet below the surface of the ground. Two charges to each root are better than one, though either loading will cut o£f the root. When Blasting Benefits Soil. An explosion in soil, like plowing it, may benefit it from a tillage standpoint when dry, and harm it when wet, though this is not true of all soils in equal degree. The explanation lies in the fact that wet soil parks under the pressure of the gases, but dry soil crumbles and breaks apart. The pot hole or cavity underground, familiar to anyone who has blasted in wet soil, is largely due to the wet condi- tion. The earth surrounding the charge for at least half a foot is driven into the â j^M i»^ HR ^ ^y mL surrounding earth, with the result that a hollow is made, surrounded by com- pacted, hard walls like those of a jug. The test for condition is explained on page 83. Soil moist enough to be plastic is too wet to blast if the tillage \ur Is iiniKjir mr. \ c I n smiI tiiusr he ^mm mr) ^a^^^^^^m HW' Ifcl n^^ 1 â ^^^r^^ â fe K- '* » P^" tWf^- I ^*w pi >1 ? m^firr' % 'k^m m-''-'. â "'-i This stump had been obstructing the plow for fifty years, but was taken out in half an hour. 7/.
