THE SILK WORM. 43 



also been known to arrest the disease after it had be- 

 come epidemic and threatened the destruction of the 

 whole family. It is a cheap article, a dollar's worth 

 being sufficient for a large establishment. The man- 

 ner of using it is simple. Put an ounce or two on 

 plates, with a little water, and set them in different 

 parts of the cocoonery, replenishing every four or 

 five days. It may also be put in a jug, or demijohn, 

 and a gallon of water added for every pound. Sprin- 

 kle the floor with a little of this solution three or four 

 times a day, when there is an offensive smell in the 

 room. 



In very hot weather, when it would be unsafe to 

 cool the room by sprinkling cold water on the floor, 



Si consequence of the vapor evolved,) it will be of 

 e greatest importance to have this solution, as it 

 may be sufely used. Should they, however, after all 

 these precautions, become diseased, the only remedy 

 is to purify the air of the cocoonery, or convey them 

 to another apartment. 



We have been thus particular in the description of 

 the diseases of the Silk Worm, not because they are 

 peculiarly liable to disease, but that the culturist 

 should have a knowledge of them, should they appear, 

 which is not much to be feared if the proper precau- 

 tions and preventives are duly regarded. 



THE COCOONERY. 



For the accommodation of the Worms during the 

 season of feeding and making their cocoons, a labra- 

 tory, or, as it is of late, more commonly called, a co- 

 coonery, must be provided. Every thing, however, 

 that is indispensable, is to have a building inclosed in 

 uch manner as to exclude the rain and chilling winds.
