Place all toolsand equipment a safe distance away from the tree, butnot on the escape path.Then, determine the placement of the felling notch (fig.21). The felling notch when properly placed determinesthe direction in which the tree will fall. It is made perpen-dicular to the line of fall and should be as close to theground as possible.Cut the felling notch to a depth of about one-fifth to one-fourth of the trunk diameter (fig. 22). It should be in no casehigher than it is deep. Make the felling notch very care-fully.If the tree has large buttress roots, cut into the largestbuttresses vertically first (horizontally next) and remove(fig. 20).
