where the apple trees are trained, as some insects 
may be there lodged. It would be tedious to use 
the brush for standard or large trees, but much good 
might be done by the following practice ; — Should 
the application of the mixture be deferred till the 
insect becomes plentiful, it would be well in the 
first place to force spring or soft water copiously 
over the trees with the engine, to break or dislodge 
their secretions, that the mixture may be forced 
more effectually amongst them with less waste. 
The mixture must be then applied with the engine 
as before-mentioned, and in two or three days after 
the operation must be repeated. To make the 
mixture more powerful, one gill of train or fish oil 
may be added to each gallon for the autumn opera- 
tion, though it proves rather injurious to the tender 
leaves or buds if applied in the spring or summer 
months. At all times the mixture should be applied 
as warm as it can without being injurious to the 
leaves or young shoots, and in summer time it 
should be applied in the evening, when the sun 
is not so powerful as to injure the trees. 
It may not be improper to observe, as this 
great pest to the apple tree has become so general all 
over the kingdom, that it perhaps would be of great 
use in making new plantations of apple trees, not to 
plant standards or long stemmed trees, but dwarfs, 
either as espaliers or not, and to keep those un- 
trained well pruned or low in their growth, in which 
case they may be planted much nearer to each 
other, and not much less produce will be obtained.
