 large trees to cut only two notches, but cuts are also required at 

 the other sides, though they should never be as deep as the 

 principal notches in the direction of the fall. Small trees may 

 be felled by one man, trees from 10 to 12 inches in diameter by 

 two men working together, and very large trees by four men.

the tree is to fall, and continued to about \ or -Ith of its 



diameter, and a notch in direction {a)

The saw is then taken to the oppo-

 cut (c) is deep enough wedges are in- 

 serted behind the saw, and from time to 

 time driven further until the tree falls.

 dense growth in which there is no 

 room to use the axe. Saplings [are 

 felled with one blow of the billhook, 

 but if a stem is too thick for this, it should be felled with two 

 blows on opposite sides, without making a regular notch.
