CHAPTER. Tt: 
IMPLEMENTS THAT FACILITATE THE RAISING OF SILK. 
The room in which the rearing is to be done should be so arranged 
that it can be thoroughly and easily ventilated and warmed if desirable. 
A northeast exposure is the best, and buildings erected for the express 
purpose should combine these requisites. If but few worms are to be 
reared, all the operations can be performed in trays upon tables, butin 
large establishments the room should be arranged with deep and nu- 
merous shelves, ranging one above the other from floor to ceiling, as 
shown in Fig. 7. The width of these shelves should not exceed 5 feet,

as those in charge must be able to reach from either side to the middle 
of each table. Bearing this in mind, the dimensions of these tables may 
be made to suit the room in which the worms are reared. The vertical 
distance between two shelves should not be less than 20 inches, but if 
this space is greatly increased it will be found inconvenient to obtain 
brush of sufficient length to form the arches upon which the cocoons are 
to be spun.
