Canton and Sainam makers believe it is an excellent plan to 

 sun jars. Limited space in Canton makes this impossible ex- 

 cept on a small scale. 



Making soy from rice. — Many of the village people make their 

 own soy from the rice that has stuck to the bottom of the ves- 

 sel in which it is boiled. A handful of rice is pressed into a 

 ball and sprinkled with hot water. These balls are placed in 

 a covered jar and allowed to mold. In about two weeks these 

 balls are placed in salt solution, using one part of salt to five 

 of water. Two parts of rice are used to three parts of salt solu- 

 tion. The more rice used the stronger the sauce will be. This 

 is then sunned as the regular soy and produces a very inferior 

 grade of rice soy, which is used by the poorer classes of Chinese 

 as a substitute for the soy-bean sauce.
