which are freest from blight, as will readily appear from 

 what has been said. 



FROST BLIGHT 

 docs not differ from the blight we have been speaking of. 



INSECT BLTC.HT. 



In May and June, shoots at the ends of branches, 

 extending not beyond the wood of two years growth, 

 turn dark in color, and the leaves soon turn black, and 

 the wood becomes shriveled and very hard. Where 

 this blight starts, or near it, will be found the cause. It 

 is caused by the egg of a beetle, (Scolytus Pyri.) 

 deposited there the year before, in July. The beetle is 

 small, deep brown, with light brown limbs. Thorax 

 short and studded with bristles. The wings have 

 punctured points, and between these points are rows of 

 bristles. The egg, having been deposited the year 

 before, hatches either then, or next May or June, on 

 the Peninsula, and then the small grub or larva bores 

 through the sap wood, going in at the root of a bud, 

 and burrows toward the centre of the limb. The branch 

 dies beyond the burrow, and we have insect blight. 

 The grub now completes his transformation and passes 

 out, and we have the beetle again, as heretofore 

 described, and on it goes to lay its eggs, and thus with 

 it the wheel of nature revolves.
