branches are too stout for these pruning-saws (Figs. 80 

 to 82) will have to be used. When trees have to be 

 removed they can be felled by felling-axe or saw, or by 

 the two combined, or if they have no marketable value 

 they can be girdled, unless they belong to those species 

 which are not killed by girdling. In girdling a tree 

 care should be taken to thoroughly clear the bark down 

 to the cambium; and to let no strands of bark or bast 

 remain to join the upper and lower lips of the wound.

This is particularly liable to happen with trees which 

 have grooves running down their boles. Unless the 

 bark is thoroughly cleared, the strands of bast left may 

 be sufficient to preserve the life of the tree. When 

 removing whole trees over seedlings of valuable species, 

 great care should be exercised, especially where fast- 

 growing brushwood is liable to spring up, not to carry 

 out this operation with too heavy a hand. I have seen 

 a wood in the Himalayas where girdling, which was to 

 foster the growth of young deodar cedar, only led to the 

 whole area being overrun with brambles. Wholesale
