I say water will not destroy the insect in the 
manner generally recommended ; for we find, as 
soon as the leaves again become moderately dry, 
it renews its attacks. Besides, how is it that 
they survive the winter months ? Can they 
escape the long-continued and heavy rains and 
snow which are common at that period, when 
their protection is nothing better than crevices in 
the wall and trees, and sometimes in the earth ? 
And, I may say, that nearly half of the year 
aftbrds them but little relief from damp, if not 
actual rain or snow, and yet, at the spring, as 
before mentioned, when the weather becomes ani- 
mating, they do not appear, as generally supposed, 
dead, but actively wandering over the trees. 
But it may be said some will be protected 
from wet deep in the wall and other concealments. 
This may be allowed ; but on one occasion, 
when endeavouring to prove the effect of water, 
I macerated a number of the Spiders, Acarias Te- 
larius, three hours with the leaf of a Peach tree, 
on which they were feeding, in clear water, with- 
out one being destroyed ; and upon one occasion 
twelve hours, and yet some survived ! and can 
it be supposed that those tenacious animals will 
be drowned with a shower of rain, or a good 
watering with the engine, when they escape de- 
struction after being deluged so long under 
water. 
The Thrip.— The Thrip makes its attacks 
on those trees similar to the Spider, as soon as
