A wound made by a cut on the dotted line A-B will be promptly healed. One made on the line C-D or E-F will not. In Fig. 154 the lower branch was cut o£E too far from the trunk. Fig. 154. Showing how to make the cut in pruning large branches. The upper cut, all made from above, permits the branch to split down. The left cut, first made partly from below, prevents splitting down.

Cut on the dotted line, the uppermost bud would form a shoot tending to horizontal. line, will usually heal promptly, but if the cut is made much farther out, it will not. "Wounds so large that they cannot heal promptly should be painted with lead and oil paint to preserve the wood. 419.
