THE SILK WORM, 
of any bird. When a grub has come out of one of 
the eggs, it will be put into a new tray, made deep 
on the side, with a leaf or two from the tree it is 
most fond of, to eat. When it has been left here 
for some time, it will spin its web in the way I have 
just told you. If the silk is left on the grub it will, 
in time, bite its way out, and then it will not be a 
grub, but a moth, and the silk will be of no use. 
It will take many and many a web to make up a 
yard of silk as we see it ! Silk, when it is on the 
grub, is a fine buff, not very dark, and is very soft. 
We use silk in many ways, to sew with, as well as 
to wear ; and when you see the ball of silk on the 
Silk Worm, you will find how much will have to 
be done to it to make it fit for us to put on. We 
do not get much silk from our own land, for the 
Silk Worm will not live in any but a very warm 
spot ; so that if a very cold wind were to blow upon 
it at any time, it must die.
