bered millions of trees annually, the various 

 species of another group of beetles known as 

 weevils are active in deforming and injuring 

 even a greater number. They mutilate and 

 deform trees by the millions. The work of the 

 white-pine weevil is particularly devilish. It 

 deposits its eggs in the vigorous shoots of the 

 white-pine sapling. The eggs hatch, and the 

 grubs feed upon and kill the shoot. Another 

 shoot bursts forth to take the place of the one 

 killed; this is attacked and either killed or in- 

 jured. The result is a stunted, crooked, and 

 much-forked tree. 



Borers attack trees both old and young of 

 many species, and a few of these species with 

 wholesale deadly effect. Birches by the million 

 annually fall a prey to these tree-tunnelers, and 

 their deadly work has almost wiped the black 

 locust out of existence. Borers pierce and hon- 

 eycomb the tree- trunk. If their work is not 

 fatal, it is speedily extended and made so by the 

 fungi and rot that its holes admit into the tree. 



Trees, like people, often entertain a number 

 of troubles at once and have misfortunes in
