the Mixture of tobacco and black pepper is quite 
useless. The tobacco might make the Caterpil- 
lars intoxicated, but they would recover in a short 
time. As for the pepper, I think it would not do 
more than make their food palatable, for I may 
venture to say the quantity mentioned would fall 
far short of seasoning a beef-steak pie, of a size 
requiring the same quantity of gravy as water 
here required to compose the Mixture, and if ten, 
or even twice ten times the quantity was used to 
the same quantity of water, it would not destroy 
them, and how much less useful it must be where 
half an ounce only is introduced to eight gallons of 
water with other ingredients for Peach and Nec- 
tarine trees. After the spring watering', a little 
lime is directed to be laid under the h'ees, but I 
am at a loss to know for what purpose. The 
smoking, it is possible, may be of some use, but 
I doubt whether it will destroy when applied in 
this manner. 
I do not know any thing about the destroying- 
powers of Cow urine, which Maemurray strongly 
recommends. If it has those destroying proper- 
ties, it is probable the application may fall on 
some of the straggling Caterpillar's, which may 
have only just left the bush to conceal themselves 
in the earth ; but the principal bulk, at this time, 
will be coated over with a shell that would resist 
almost any quantity that might be applied, and 
at the same time the Caterpillar does not always 
retire immediately round the stem of the busli.
