SILK 10JJ 



der the action of the machine the thread of silk un- 

 winds while the cocoon jumps about in the hot water 

 like a ball of wool when one pulls the yarn. 



"In the center of tlu 1 threadbare cocoon is the 

 chrysalis, scorched and killed by the fire. Later the 

 silk undergoes divers operations which irive it more 

 suppleness and luster; it passes into the dyer's vats 

 when' it takes any color desired; finally it is woven 

 and converted into fabric."
