of wood-ashes or dissolved
potash. Apple-trees will bear it strong enough to kill some of the
finest cherries. We add another very effectual wash. Let cultivators
choose between the two. Into two gallons of water put two quarts of
soft-soap and one fourth pound of sulphur. If you add tobacco-juice, or
any other very offensive article, it will be still better.

_Apple-worm._--The insect that produces this worm lays its egg in the
blossom-end of the young apple. That egg makes a worm that passes down
about the core and ruins the fruit. Apples so affected will fall
prematurely, and should be picked up and fed to swine. This done every
day during their falling, which does not last a great while, will remedy
the evil in two seasons. The worm that crawls from the fallen apple gets
into crevices in rough bark, and spins his cocoon, in which he remains
till the following spring.

Bonfires, for a few evenings in the fore part of June, in an orchard
infested with moths, will destroy vast numbers of them, before they have
deposited their eggs. This can not be too strongly insisted upon.

_Bark-louse._--Dull white, oval scales, one tenth of an inch long, which
sometimes appear on the stems of trees in vast numbers, may be destroyed
by the wash recommended above.

_Woolly aphis_--called in Europe by the misnomer, _American blight_--is
very destructive across the water, but does not exist extensively on
this side. It is supposed to exist, in this country, only where it has
been introduced with imported trees. It appears as a white downy
substance in the small forks of trees. This is composed of a large
number of very minute woolly lice, which increase with wonderful
rapidity. They are easily destroyed by washing with diluted sulphuric
acid--three fourths of an ounce, by measure, from the druggist's--and
seven and a half ounces of water, applied by a rag tied to the end of a
stick. The operator must keep it from his clothes. After the first rain
this is perfectly effectual.

_Apple-tree borer._--This is a fleshy-white grub, found in the trunks of
the trees. It enters at the surface of the ground where the bark is
tender, and either girdles or thoroughly perforates the tree, c
