THE ART OF REARING 
quire, until the first moulting of the skin, a space 
of about seven feet ten inches square. 
Until the second moulting, a space of about fif- 
teen feet four inches square. 
Until the third moulting, a space of thirty-five 
feet square. 
The hurdles, or wicker trays, should be placed 
above one another, at a distance of twenty-two 
inches at least ; and as many should be put as are 
required to give the number of square feet ne- 
cessary for the quantity of silk-worms which are 
to be accommodated. 
The worms must be kept upon paper, which 
should line the wicker trays, and extend a little 
beyond, to prevent the worms falling off. 
Upon this paper, which should be rather strong, 
ought to be inscribed the corresponding num- 
bers to those on the boxes ; thus avoiding every 
chance of the silk- worms of different boxes being 
mixed. 
According; to the size of the room, there should 
be one or more thermometers. One or two small 
fire-places placed in the angles, one or two ven- 
tilators in the ceiling, or in the floor, and one or 
more windows ; and also as many doors as may 
be convenient. In this room I also w r ould re- 
commend a stove similar to that in the stove- 
room, as in cold weather it may be of use to save 
fuel.
