there had been a time more pointedly specified for 
the performance, we should have been better able 
to judge, for, from one end of the autumn months 
to the other, it will be found, from the account I 
have laid down, the change of these animals is 
very material. At the fore parts of the months 
the perfect insect and egg exist on the leaves toge- 
ther, and at the latter end there are no eggs, and 
the insects have entered their retirement. At all 
events, if one of the ingredients recommended 
w'ere used much stronger, viz. the soap to six 
gallons of water instead of eight, applied at a 
proper time, as I have before directed, probably dt 
would be found useful for the destruction of the 
insect, but not the egg. The other ingredients, as 
I have said before, are quite useless. 
The only benefit derived from wjiter, so gene- 
rally recommended for the destruction of these 
animals, as far as I can judge, will be this : 
From the time of its application, till the leaves 
again becomes dry, the Spider abstains from 
feeding upon them. But this can only be done 
to a certain degree, to be advantageous to the tree, 
which is better known by practical gardeners than 
myself, and, when properly attended to, no doubt 
but health and vigour will be promoted by it. 
So far w'e may pronounce watering to be 
good ; but in respect to its being applied for the 
destruction of the insects, I cannot coincide with 
the numerous authors preceding me, and say that 
it is effectual for that purpose, but to the contrary.
