on the leaves. The pattern on the wings of the moth becomes more 
strongly marked, its movements are much more lively, and it makes 
use of its wings as much as its naturally sluggish nature will allow it 
to do.” The singular entomological fact is stated, that at first the silk- 
worm has much difficulty in holding on to the tree in very windy weather, 
and often lets itself drop by gnawing through the stalk of the leaf on which 
it is feeding; butin a few years the caterpillar becomes stronger and ape 
lively, the moth more alert, and the insect “ completely regenerated,’ 
and its eggs, exempt from disease, promise an unfailing return; for the 
following year. 
The mulberry-trees, in accordance with M. Roland’s plan, are grown 
as standards, headed down at a height of three feet, so as to resemble 
a Standard rose. They are pruned or pollarded every spring, the object 
being to secure the formation of a number of young shoots, with fresh, 
tender leaves, the older, harsher leaves not being suitable for the insect’s 
food. 
The annexed cut, copied from the London Gardener’s Chronicle, wil? 
illustrate the method of proceeding. 
Over the head of the tree, as will be seen, is fixed a hood or cover of 
wire gauze and canvas, about 
three feet in diameter, the top 
and bottom being made of 
fine painted canvas. This 
hood is slipped over the tree, 
the lower end being tied care- 
fully round the trunk, with in- 
tervening wadding, so as to 
prevent injury to the tree, as 
well as egress of the worms or 
ingress of other less desirable 
insects. The silk-worms are 
placed on the head of the tree 
through the upper opening of 
the hood, which is then closed 
carefully, like the. bottom. 
Two stakes, one on either side, 
are then thrustinto the ground, 
and the hood is made fast te 
them to secure steadiness. In 
spring the worms are hatched 
naturally at the same time 
that the shoots make their 
appearance, and when they 
have nearly eaten the leaves 
of one tree they are shifted 
to another. Thirty trees and 
ten hoods will rear silk-worms 
sufficient to produce an ounce 
of eggs. 
It will be observed that this
