scription of its process, see on Peaclies and Nec- 
tarines ; make use of the Mixture (No. 3) in the 
some manner as directed. 
ScAiiES AND Cocci. — This tree is liable to 
be attacked in all parts by a species of the Scales, 
or Cocci. It is of a very small size, so that if 
the bark of the tree is not smooth and fine, and 
the insects numerous, they will easily be over- 
looked by those who are not acquainted with them. 
They tend greatly to injure the health of the tree 
and flavour of the fruit. I have seen, where trees 
have been neglected, especially against walls, those 
little insects prevail to such a degree, that the tree 
has not had sufficient sap to produce young wood, 
or to bring forth the fruit to half its proper size, 
and in flavour worth nothing. For a farther de- 
scription and their destruction, see on Peai’s. 
Large Scale. — If trees should be attacked 
by the large Scale, described on Grape Vines, 
and the one on Apricots, let the same means be 
applied as directed respectively on the Vine and 
Apricots. 
As various kinds of insects are often intro- 
duced from the nurseries with young trees, it 
would be advisable to immerse or brush all young- 
trees, which are received from nurseries, before 
they are planted, all over the roots, as well as the 
stems, with the Mixture for the American Blight, 
(No. 3.)
