to 60,000 artificially grown terrapin are 

 placed on the market annually. With- 

 out any outside aid or suggestions, the 

 Japanese have evolved special methods 

 for the cultivation of many kinds of 

 mollusks, including the pearl oyster, the 

 ark-shell, several clams, and various 

 other lamellibranchs, and, in addition, 

 the common oyster. That the Japanese 

 should realize the importance of oyster 

 culture is not strange ; but that they 

 should have taken it up a century before 

 our nation was born and have recognized 

 the most essential factor in successful 

 cultivation, namely, individual owner- 

 ship or control of the oyster bottoms, 

 comes as something of a shock to our na- 

 tional pride when we remember that in 

 the most important oyster region in the 

 world, within a short distance of the 



Capital of the United States, the vital 

 principles of oyster culture are ignored 

 and efforts to apply them are resisted 

 sometimes by force of arms. The culti- 

 vation of oysters has reached greatest 

 perfection in the Inland Sea near Hiro- 

 shima, and some very ingenious meth- 

 ods have there been evolved, which are 

 described in a paper by Dr. Bashford 

 Dean recently published by the U. S. 

 Bureau of Fisheries.
