dom, for these secreted enemies to consume whole, 
or nearly whole, crops of cherries. This tree 
appears, if any thing, more resorted to than the 
trees already mentioned, especially by the two first 
species described on the Apple. About the time 
that the flowers are bursting the envelopment which 
incloses each group, and when separating' from 
each other, they leave their cells, and often enter 
the flower while it is yet green, several days before 
it expands, and feed at first upon the fructification

expand. This is often sufficient to deceive the 
proprietor or gardener, who are not minute ob- 
servers, and leave them to conclude, when fruit 
should appear, that either white frost, cold winds, 
blasts, or heavy rains, have destroyed it. 
For their destruction. — On a fine

(No. 3) with the engine ; or, if their destruc- 
be delayed till they are folded up in the leaf,
