Tue Insects OF EARLY Sprinc.—In April the Gardener should 
scrape and wash thoroughly all his fruit trees, so as to rub off the eggs 
of the Bark Lice which hatch out early in May. Many injurious cater- 
pillars and insects of all kinds winter under loose pieces of bark, or un- 
der matting and straw at the base of the trees. Search should also 
be made for the eggs of the Canker Worm and the American Tent 
Caterpillar, which last are laid in bunches half an inch long on the ter- 
minal shoots of many of our fruit trees. A little labor spent in this way 
will save many dollars’ worth of fruit. The “castings” of the Apple 
Tree Borer (Saperda bivittata) should be looked for at the base of the 
tree, and its ravages be promptly arrested. Its presence can also be 
detected, it is said, by the dark appearance of the bark, where the grub 
is at work: cut in and pull out the young grub. It is the wid oe of 
the year to catch and kill this pest. Cylindrical bark borers. h are 
little round black weevil-like Beetles, often causing ea 
pears, etc., are now flying about fruit trees to lay their eggs; and
