about the 24th of October, it eats out of the leaf, and crawls down the branches 
and stem, until it has found a convenient place to fix its cocoon. This is the 
only time when it finds it necessary to make use of its legs, which seldom exceeds 
an hour, sometimes less. After having found a suitable place, which is generally 
about the spines and offsets of the branches, it begins to form its cocoon, by 
stretching out its body and attaching a thread to the branch. It then turns its 
body to the other side, fastens it there, and by proceeding in this manner on all 
sides, keeping the hinder part of the body fixed, it forms the upper part of the 
cocoon, or that exposed to the weather, which is convex, and generally circular. 
The under part is oblong, shaped to hold the pupa; it is much smaller than the 
upper, which projects considerably beyond it on all sides. At one end the threads 
are not interwoven, and leave a space through which the pupa can force a 
passage. This remarkable cocoon is very flat, and at first of a pure white, which 
is changed by the first shower of rain to a light orange. It afterwards assumes a 
deep brown colour, so nearly resembling the bark of the rose-tree as only to be 
distinguished by a practised eye. This change takes place very rapidly. The 
pupa is light brown, of an oval shape, about a line long, and half that in breadth. 
The perfect insect is produced in May; it is the sort called the Red-headed 
Pigmy; the upper wings are gold-coloured (Ent . Mag.) with the hinder margin 
purplish, the head being reddish, and the expansion of the wings 2f lines.

Will some of your Readers give me further Information on the 
Culture of the Auricula ? —Being desirous of having a good bloom of Au¬ 
riculas this spring, I was induced to try Mr. Revell’s plan of growing them, as 
detailed in Vol. 1, page 56, which has answered exceedingly well for some sorts, 
but not for others. The green-edged varieties grew and bloomed very fine, but 
the grey sorts succeeded very badly. Will Mr. Re veil, or any other of your cor¬ 
respondents, have the goodness to inform me whether the grey varieties require 
different treatment from the green ones? A Lover of Auriculas. 
Is there not an Error in the Wood-Cut on Page 259?—Your Wood- 
Cut, page 259, at ( c ) represents the shield with an oval top, instead of being cut 
across, that the bark of the bud may join the bark of the stock, on which, I be¬ 
lieve, entirely depends the success of the operation. C. C. C. C. 
London , June 3rd. 1833. 
ANSWER.-~That which at ( c ) appears like an oval top to the shield is intended 
for the bud itself, which the upper figure (a) will explain. 
How to Understand the Force-Pump. — l should have understood the 
pump, page 274, much better, if it had been described by letters, a, b, <$rc. At 
present it seems to me to be a contrivance for letting water fall, in order to have 
the pleasure of raising it up again.
