however, make the first drawing in from three to four months. 

 At night or when it rains, the jars must be covered with bam- 

 boo covers. This sunning process results in an evaporation of 

 the liquid in the jars; and three days before the drawing off 

 of the soy, salt solution is used again to fill the jars. The first 

 drawing is then made by siphon, kwo kong lung ( ^ ££ $ | ) 

 (Plate III, fig. 1). About 60 catties of the liquid are drawn off. 

 This liquid is allowed to settle and is again drawn off, reducing 

 the quantity to about 50 catties. It is then placed in clean jars 

 and allowed to sun again for from one to six months. Some 

 of this soy is at times allowed to sun for three years, but this 

 is too expensive and is rarely done commercially. 



First drawing. — This soy is called teng ch'au (if ifa ) , "first 

 drawing." The material that remains in the jar is called teng 

 shi ( Jg> Q?), "first salted," and is sold as a separate sauce, used 

 as the base of a number of different sauces or as the base for 

 the "second drawing," i ch'au (~ 3ft) • 



Second drawing. — A salt solution of 150 catties of water and 

 30 catties of salt is now poured on the teng shi, or the beans 

 which remain in the jar from the first drawing. The jars are 

 again placed in the sun for from one to two months. Salt water 

 is again added three days before the drawing, after which the 

 soy is drawn off, about 50 catties, after it is cleaned, and placed 

 in the sun from one to two months. This is called i ch'au 

 (Z2 3ft), "second drawing." The material which remains in the 

 jar is called iin shi (J§f g£), "beginning salted," and is sold as 

 a sauce for 4 cents per catty, used as the base of a number 

 of other sauces and as the base for sdm ch'au (H •[&)> "third 

 drawing." 



Third draiving. — The same method is used in the making of 

 sdm ch'au as in i ch'au and the material which remains is called 

 chung shi (tfi %\), "middle salted." This is sold as a sauce at 

 2 cents per catty, used as the base of a number of different 

 sauces and as the base for sz ch'au (Jjg Jjfj), fourth drawing." 



Fourth drawing. — This is made the same as i ch'au, sdm ch'au, 

 and sz ch'au, and the material left in the jars is also called 

 chung shi ( t£ |£) and is sold as a sauce at 1 cent per catty ; it 

 is used as the base of a number of very cheap sauces. 



Boiling method. — The sunning method takes so much time that 

 many of the manufacturers boil the second, third, and fourth 

 drawings instead of sunning them. This makes a decidedly
