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 tact 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 

 mouths 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 web worm in May and June; it means the 

 destruction of the larvae 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. 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.
