On the other hand, light soil will not confine the gases of explosives nearly as well as clay. In sand the greater ease of tearing the roots loose is more than Kinds of Soil offset by the lowered efficiency of the blast. The foregoing principles should be of more actual ser- vice to land clearers than a description of the conditions in different sections. If your stumps are Southern long-leaf pine, you know they will not sprout, and are of the tap-root class. If they are white pine of Michigan or Maine, you know they are of the semi-tap-root class, that they will not sprout and that they m^imAAi,. This picture shows what they look like when down. The roots are torn out better than they would have been without the tops to pull them over. Note how easily they can be sawed or chopped. II.
