catch the smaller pieces, for were they to be left 
without means being used for their destruction, they 
would issue forth at the spring, and ascend the tree. 
Forsyth, Harrison, and Abercrombie 
exemplifies it as being like a boat or keel turned 
wrong side up, meaning, no doubt, the shell, as 
the insect has no such appearaance. 
Forsyth and Abercrombie recommend as 
follows : — When these insects first appear on the 
bark they should be scraped off with a wooden 
knife, and the stem and branches of the tree well 
washed with soap suds and urine, ajiplied with a 
stiff painter’s brush, and should be done in Febru- 
ai’y, before the buds begin to come out.” 
Harrison recommends the tree being scraped 
with a blunt knife, siniilai’ to what is communi- 
cated by Forsyth, and then to be anointed with 
the following Mixture “ To four gallons 
of water add half a pound of common suljihur, 
half a pound of soft soap, one ounce of nux 
vomica, two ounce of black pepper. The nux 
vomica must be grated small previous to the 
boiling’ of the whole. After being mixed toge- 
ther, they must be boiled for half an hour, this 
will completely destroy any insect of this kind 
which may be left upon the tree.” 
The practice of scraping the trees by the above 
authors certainly will be productive of some good, 
providing a cloth be spread, as Harrison directs 
us, to catch the eggs ; but as for the Mixture 
they recommend to be aj)plied after the scrajiing'.
