would not afford protection to their progeny, 
and that a more secure abode must be resorted 
to. In this state and situation the eggs, 
which are quite round, of a faint red, remain 
du ring the winter months, and survive the most 
inclement weather. They become animated about 
the fore end of May, and produce the Spider as 
above. The effect of their depredations will evi- 
dently appeal- by the leaves which they annoy 
turning brown, as though they had been scorched 
by the sun’s rays. Dry warm weather is most 
congenial to their progress, as the reverse renders 
them torpid, which naturally causes them to 
abstain from feeding. Trees numerously infested 
by them present a very unsightly and sickly 
appearance, more like the fall of the leaf at the 
back end than the summer season. 
For their destruction, the Mixture 
(No. 3) should be applied all over the tree, with 
the engine, about the middle of June, the middle 
of September, or any other period, when they are 
not in the egg state, but the former period, and 
sometimes the September months will be the best, 
when the fruit will not be injured with the 
mixture. 
The Thrip sometimes prevails to the injury 
of the fruit and foliage of this tree, especially on 
those that are trained against walls. The effect 
produced on the leaves is similar to that produced 
by the Red Spider, except that they appear a little 
more spotted, as the bite of this insect is something
