applied without injury to vegetation, especially to 
the buds of all kinds of trees and plants. 
For the destruction of the Aphis, it 
will be proper to look over the trees as soon as the 
buds begin to open out, or rather about the time 
when the corticated envelopment has buret which 
contains the flowers, and while the petels are still 
unexpanded. By the time that the petels expand, 
or perhaps before, the whole of the insects will 
liave left the egg. The preparation (No, 1) may 
be applied, as warm as the hand can be just borne 
in it, with the engine, by pressing upon the pipe 
with the fore finger, and suflering it to escape like 
fine rain, so that the tree may be wet all over, 
without much waste. At the same time, it should 
be applied with as much force as possible, which 
assists it in spreading .md entering into the cre- 
vices of walls and trees. It will be of farther 
advantage to use a whisk, beating it carefully up- 
wards to save the liquid, and that the insects on 
the under sides of the leaves, may receive it more 
effectually. Care should be taken not to apply it 
in the evenings, as, at this time of the year, white 
frosts are very general, and the wet would consider- 
ably assist the frost in destroying the bursting buds. 
The best time is from five o’clock to eight in a 
morning, which gives time for the trees to get 
moderately dry before the sun becomes powerful, 
which might otherwise scorch the leaves or tender 
buds. As some of the leaves undoubtedly will 
escape this operation, they should be frequently
