by cutting about half way through the branch from beneath at a 

 point marked A in figure 43, which may be about six or eight 

 inches beyond the junction. The final cut is then made from 

 above and close to the parent branch as shown at B in the 

 diao-ram. By the time the saw reaches the center, the branch 

 win split horizontally at X and drop off, when the cut may be con- 



Fig, 43. Diagram to illustrate the method of sawing off a large limb 

 to prevent it from splitting clown the trunk. Cut first at A and then at 

 B, when the branch should split along the dotted line X, and drop off. 

 If the limb does not drop off when the second cut reached, the half-way 

 point, a third cut should be made at the point D, After the limb has 

 dropped off the final cut may be made through to C. 



tinned through to C. Sometimes with tough-wooded trees and when 

 there is a large shoulder at the base, the branch may not split 

 readily when the second cut reaches the half-way point or the 

 level of the ending of the first cut. In such cases a third cut 

 should be made from above at the point D, just beyond the first 

 cut. When these two cuts meet on the same level the limb will 

 drop off, when the final cut may be finished. 



All cuts should be made smooth and close to the parent branch, 

 which forms the callus to heal the wound. AYhen there is a 

 large shoulder at the base of the limb to be removed, there is 

 always a temptation to make the cut beyond the shoulder and at 

 right-angles with the branch. Wounds made by cutting in this 

 direction, although much smaller, will not heal over as readily
