Sang gives a coiu-se of information of the 
different experiments for the destruction of the 
Caterpillai’s infesting fruit trees, and, after la- 
bouring for several years in pursuit of a proper 
plan for their destruction, he at length appeal’s to 
have hit upon the point, and illustrates it as a 
most effectual one. It is as follows ; “ In the 
beginning of January last (1810), I took five 
pounds of flowers of sulphur, three pounds of soft 
soap, one pound of potash, four pints very strong 
tobacco liquor, the expense of all is but trifling, 
and made up the mixture to ten pints with fresh 
water. I put the mixture on the fire in a pot, and 
when as intimately mixed as possible, I applied 
it in a lukewarm state, with a painter’s small 
brush, so as not to miss a single bud, and potful 
after potful ivas mixed up, till I had w'ashed 34 
full grown trees, Apple, Pear, and Cherry.” 
The most useful information that can be ga- 
thered from Harrison’s recipes is, that of the 
latter part of his summer operation, pinching those 
to death which escape the lime and lime-water, and 
that will include all that were living before the 
operation of lime, and solution of lime, as it cer- 
tainly has no effect towards their destruction, and 
therefore the latter practice, pinching to death, 
had much better be adopted at the first, and pre- 
vent the tree being’ disfigured with the lime-dust.
