effectually to destroy them, 1 would advise, that 

 from the first to the middle of August, some 

 swingling tow, a piece of hairy hide, (the hair 

 inside, but turned over at top,) or some other 

 coarse thing of six or more inches in width, be 

 tied close around the trunk of the tree, the under 

 edge to be a little covered with earth, so as to 

 prevent any passage beneath; about the middle 

 of September remove the bandage, and imme- 

 diately give the whole trunk of the tree a cover- 

 ing of soft soap or lime-wash, well brushed on, 

 that no spot from the head to the root may 

 remain untouched. Perhaps a decoction of 

 tobacco, or some other wash, might do better; 

 even hot water would be effectual, where the 

 tree was sufficiently hardy to bear the applica- 

 tion; or it may be, that the wash would answer 

 the purpose without the bandage, but where the 

 bandage is dispensed with, the wash ought, I 

 think, to be applied about the first of September, 

 or I should have great confidence in a bandage of 

 tobacco leaves or stems; it should be kept on 

 from the first of August to November, and 

 could do no damage by being continued, provided 

 it was not tied so close as to cramp the growth 

 of the tree.
