An iron bolt may be run through the base, hold-

of the bolt should be large, so that they will not 

 draw into the wood. The bolt should fit tight 

 in the auger hole. When the work is done, apply 

 paint or other covering at the place where the 

 bolt emerges. The bolt will soon be buried, as 

 the nail is buried in Fig. 7G, and the tree does 

 not suffer.
