House & Garden 
(Left) A maple treated 
late in 1920 started heal¬ 
ing growth immediately 
Fine healing over filling 
promises new life to this 
tree 
A tree wrongly braced 
with iron was injured 
and broke its girdle 
An old tree, carelessly patched, 
gradually began to lose its cement 
filling and to decay 
The old patch removed, the cavity was 
cleansed, sterilized and braced ready to 
receive the new filling 
The filling in place. This is in sec¬ 
tions, allowing the tree to sway with¬ 
out breaking the cement 
A frost crack such as 
this can never heal 
without help 
Fungous growth start¬ 
ed in a sterilized but 
unfilled cavity 
Rounded top cavities 
rarely heal without 
rapid growth
