Lopping of Tops In some forests the burning of the brush may be unnecessary or actually undesirable. A method of brusli dis- posal applicable in many forests is to lop off the branches from the tops and leave the material on the ground. The purpose is to bring all the brush in close contact with the ground, so that it will absorb moisture more readily, dry out less in summer, and decay more rapidly than when propped high above the ground. So far as the author is informed this method was first used on an ex- tensive scale in the Adirondack Moun- tains in lumbering spruce and pine. At first the plan was to cut off only the upper branches of the top as it lay on the ground. This left the stem still propped above the ground. (PI. VI, fig. I.)''' The next step was to cut off the under branches and lower the whole mass to the ground. The heavy snows during the first winter after cut- ting flattened down all the branches. (P1. VI, fig. 2.) In this condition the brush absorbs moisture so rapidly that after three vears there is little risk of fire. This method was first used in private shooting preserves, mainly to prevent the tops from obstructing the hunter's view. It also enables a freer movement over the ground and facilitates the fighting of fires. A later development of the method is to cut up and scatter the branches about over the ground. This has been used in the cuttings on second-growth woodlands when the amount of mate- rial left after cutting the cordwood in the tops was small. It has also been extensively used in certain National Forests in the dry districts of the West, where the scatte
