REARING SILKWORMS. 51 



very dusty, as dust is not wholesome for the silk- 

 worms. 



Unless hot-air pipes can be provided, oil-stoves 

 will do for heating, but they must be a kind that 

 will not give off any odor. When the air seems 

 too dry, a vessel of water should be placed on 

 the stove. 



FURNITURE OF COCOONERY. 



The cocoonery should be fumigated every week 

 by burning eucalyptus leaves. All the ventila- 

 tors should be opened in three minutes to let the 

 smoke escape. This process purifies the atmos- 

 phere. 



Have four double racks five feet deep and 

 twenty- five feet long. These are for the large 

 room. An aisle three feet wide should pass 

 through the center of the room, between the two 

 middle racks. Another aisle the same width 

 should separate each of the other double racks. 

 In these aisles the stretchers may be placed to 

 attend to the worms. 



In the wider spaces at either side of the room, 

 two single racks can be placed between the win- 

 dows, also two common tables, that will often be 

 needed. Six or eight stretchers will be found 

 useful for many purposes, especially to lay trays 

 on when working with the worms or millers.
