The silk cocoons are gassed ; by small quantities of ohloroplcrln. I which has proved exceedingly prartl- j cal ,and easy to handle. The gas has been tried In various silk-raising con- j ters and has been found to possess marked advantages over killing the cocoons by baking or steaming. Under the prevalent methods of siik culture j the cocoons have to be all sold with- i it! period of two or three weoks, but ! the use of' chloropicrin promises a j practical way, it is said, for the grow- i ers to turn the cocoons into notiper- ishahle merchandise which can be sold j when the market is best. j i i |
