Bridgeport, found it easy to pick out the trees which had been treated 
in this way. Such elms were green, while all others were brown and 
nearly leafless. The defect of this plan as a general practice lies in 
the fact that not all property owners or residents can afford to employ 
a tree sprayer, while others are unwilling, since they deem it the busi- 
ness of the city authorities, or do not appreciate the value of tree 
shade. 
Any effort, therefore, looking toward the arousing of popular senti- 
ment or the banding together of the citizens in the interests of good 
shade is desirable. A most excellent plan was urged by one of the 
Washington newspapers in the summer of 1894, 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 is only one of several ways which might 
be devised to arouse general interest. The average city householder 
seldom has more than a half 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 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 bagworm in win- 
ter, and equally simple operations for other insects should they become 
especially injurious. Whata 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.
