SUPPLEMENT. 171 



with the silk of the provinces of Kia and Hou (see above, 

 the cocoon room, called chan-po}. That silk has been dried 

 twice, that is to say: while spinning, and afterwards in reel- 

 ing from the basin. It is not to be feared that the threads 

 of that chain will break during the tissue work. 



Extract from the same Work, (fol 31, verse L, 4.) 



The following is the manner of obtaining excellent silk; 

 it is expressed in six words : 



1st. Tchou-kheou-kan; that is to say, the silk must be 

 dried when it comes out of the mouth of the insect. For 

 that purpose chafing-dishes with small coals must be placed 

 at the bottom of the frame. See PLATE 7. 



2d. Tchou-choui-kan ; that is to say, the silk must be 

 dried when it comes out of the water. When the silk is 

 reeled, two small chafing-dishes must be placed five or six 

 inches from the reel, each containing four or five ounces of 

 lighted coal. The rapid movement of the wheel produces 

 the effect of wind. It gives activity to the fire, and causes 

 the thread that is reeled to dry rapidly. If the weather is 

 clear and bright, and a great deal of air circulates in the 

 silk room, it is not necessary to make use of fire.
