desirable. A most excellent plan was urged by one of the Wostinern 
newspapers the past summer. It advocated a tree protection league, 
and each issue of the paper through the summer months contained a 
coupon which recited briefly the desirability of protecting shade trees 
against the ravages of insects, and enrolled the signer as a member of 
the league pledging him to do his best to destroy the injurious insects 
upon the city shade trees immediately adjoining his residence. This 
was only one of several ways which might be devised to arouse general 
interest. The average city householder seldom has more than half a 
dozen street shade trees in front of his grounds, and it would be a matter 
of comparatively little expense and trouble for any family to keep these 
trees in fair condition. It needs only a little intelligent work at the 
proper time. It means the burning of the webs of the fall webworm in 
May and June; it means the destruction of the larvee of the elm leaf- 
beetle about the bases of the elm trees in late June and July; it means 
the picking off and destruction of the eggs of the tussock moth and the 
bags of the bag worm in winter, and equally simple operations for other 
insects, should they become especially injurious. What a man will do 
for the shade and ornamental trees in his own garden he should be 
willing to do for the shade trees 10 feet in front of his fence.
