load of lime was placed in the orchard, imme- 
diately after the fiill of the leaf, and was suffered 
to slaek by the weather. Advantage was taken 
of the morning' dews, to powder every part of the 
surface of the trees with the lime, while in its 
most caustic state. The trees then exhibit that 
appearanee which they assume after a fall of snow, 
or an intense hoar frost.” 
Loudon, after enumerating' the Caterpillar 
and other insects, observ'es, that burning of straw 
and other materials, under the trees, has been long 
recommended, “ but the principal thing to be re- 
lied upon, in our opinion, is regimen, that is 
judicious subsoil and surface soil, culture and 
pruning.” 
Harrison recommends for the destruction of 
these insects on the cherry-tree, as follows : — 
“ Trees infested by this insect must be forcibly 
washed over with lime-water, likewise be sprin- 
kled over with powdered quick lime. This appli- 
cation will destroy all those it reaches to, but as 
some are so closely concealed that they will some- 
times escape this operation, a few days afterwards 
the trees must be looked over, and all insects that 
escaped must be pinched to death. Although the 
directions given are effectual when pursued, yet 
it is a practice with me to destroy the insects in 
the larvae state, by the application of the proper 
composition for the Cherry-trees, at the winter 
pruning.” His composition is as follows : “To 
four gallons of water add one pound of soft soap.
