In Japan, the district where this shell-fish is most appreciated for 

 food is Kyushu ; also in the Sanyo-do and the Sanin-do which are 

 commonly called ' Chugoku ' (provinces in the middle of the country), 

 it is more or less valued as an eatable. In Kwanto, the old name 

 given to the eastern part of the Tokai-do, this custom is almost un- 

 known to people. In short, the demand for the razor-shell is very 

 small in Japan proper. The case in China is quite different. ' Shing- 

 king, ' the dried flesh of the razor-shell, is in great demand through- 

 out the empire. It is said that not less than a million pounds of the 

 same is annually imported and landed at Shanghai. Consequently 

 of such a great quantity, that which we have the honour to supply 

 and export to the empire is not a little. 



Let me tell you in brief how to make ' Ch'eng-kan.' First put 

 a quart of living shells in a large boiler, into which about three 

 gallons of water shall be poured with a pint of salt. After boiling 

 it until the victims open their mouths, that is, their ventral margins, 

 ■we take them out. Then the flesh may be separated from shells. 

 Now put all the flesh in a basket. Prepare another boiler filled with 

 about three pints of water and a pint of salt. When the water boils-, 

 put the basket in the boiler, and stir until the water boils again. 

 Then take out the basket, and dry the flesh in the sun for four or 

 five days. When thus prepared, the flesh is called * Ch'eng-kan.'
