CHARACTER OF THE 
DAMAGE. 
The damage and 
loss, as affecting the 
commercial tree, con- 
sists not only in the — 
death of the terminal ~ 
shoots, but in subse- 
quent abnormal de- 
velopment of the 
trees so injured. The 
dying of the leading 
shoot throws the next 
year’s growth into the 
upper lateral shoots, 
which results in a 
forked and many- 
branched top. Each 
branch produces a 
vigorous terminal, 
and all compete for 
leadership in forming 
the crown. In suc- 
ceeding years the 
- more vigorous termi- 
nals of the topmost 
branches are at- 
tacked and_ killed, 
causing more branch- 
es, and thus effec- 
tually preventing the Fria. 4.—Work of white-pine weevil, showing result of killed terminal 
development of the shoot in 4-year-old top of small sapling. (Original.)
