usual manner :— lst, all useless trees and brushwood are cut 
down; 2nd, all the lower branches of the useful trees are also 
cut to about three feet from the ground, as well as those 
branches which touch adjoining trees; 8rd, the trunk of the 
trees must be well exposed; 4th, all dried leaves and grass are 
removed ;—in fact the place is made as clean as any garden, so 
that the man in charge can at a glance see the worms are not 
molested. ‘The only trees I tried to rear my worms on were 
Shorea robusta (sal, sakooa) and Terminalia tomentosa (assun) ; in 
fact these are the principal ones used for that purpose. 
The eggs having been laid in boxes, I detached them with an 
ivory paper-slice, and kept them in boxes till the evening of the 
eighth day. I then had pouches made of green leaves, taking the 
precaution of making two or three small holes in the lower part, 
so as to allow the water to run out should a shower come on. 
The first time I did it I made no holes, and the natural result 
was that all my worms were drowned and eggs spoiled. This 
leaf-bag or pouch I attached to the trees, where the worms were 
to be reared, on the evening of the eighth day. On the morning 
of the ninth day the eggs hatched, and the trees were at once 
covered with small caterpillars, about three-sixteenths of an inch 
long, and one thirty-second part of an inch broad; they were 
rather hairy, and of a dark colour. ‘lhe natives attach the 
pouches to the lower branches of the trees, so that the worms 
go upwards; and when they have eaten up all the leaves, they 
being on the top of the trees, the keeper has to climb up and hold 
fresh branches with leaves where the starving worms are, keeping 
it there till the worms are on them, and then hand it to another 
man, who ties it to adjoining trees. This operation is risky, 
troublesome, and expensive, and many hands are needed. 
My method was the same, so far as removing the worm from 
one tree to another; but the day the eggs were hatched I attached 
the pouch to the tops of the trees, where young worms not: only 
had the tender leaves to feed upon, but, when they had done 
eating the leaves, they had arrived at the lower branches within 
easy reach of the keeper, who without any risk removed them as 
above described, one man being able to do as much as ten by the 
native method. ‘The worms feed two days and a half and rest or 
starve a day and a half, and before commencing to feed again they 
fix their skin to the branch and crawl out of it, which skin they
