CULTIVATION <>K MARINE AND FRESH-WATER ANIMALS IN JAPAN. 2S<t 



day you can sec hundreds of little skill's, mostly with women and young girls, going 

 out to collect it. Being brought home, the plant is thoroughly cleansed and then 

 made and dried in the shape of thin rectangular sheets about 25 by is cm., looking 

 very much like sheets of dark paper. In this state it can be kept for a long time 

 and is sold in shops. When slightly roasted the sheets have a peculiar taste and are 

 used much to give flavor to various articles of diet. The production about Tokyo 

 alone is over 1,000,000 yen, and for the whole country it must of course he much 

 more. 



"Funori" {Gloiopeltis) is used as the starch-yielding source in the manufacture 

 of various kinds of silk and cotton goods and in washing, and is one of the most 

 important articles produced by the sea. Its cultivation is not as extensive as that 

 of the amanori, hut. according to Mr. Endo, it is undertaken to some extent in the 

 village of Shimofuro, in the district of Shimokita, prefecture of Aomori, on the south 

 side of tht 1 strait between Hokkaido and Honshu. At that place there is a large ledge 

 of rock that is exposed at low tide. Here people place 700 to 800 large blocks of 

 stone, and the alga, which grows between tide marks, soon becomes attached to these. 

 A fter five or six years, when the Mocks become too old and the alga no longer grows 

 on them, they are pushed into deeper parts and new blocks are placed in their stead. 



I think I have now given — how imperfectly, I am but too well aware- a brief 

 survey of the marine and fresh water animals cultivated in Japan. The subject has 

 always been an attractive one to me. as it might in many respects be called applied 

 embryology. Aside from its immediate economical results, there are many things in 

 it which might be utilized to solve problems in heredity, growth, ecology, etc. 



In conclusion. I wish to express my thanks to all who helped me in the prepara- 

 tion of this paper. Especially 1 would mention Doctor Kishinouye, Messrs. Fujita, 

 Mikimoto, NishikawaJWada, Fujimura, and Ilattori. To Mr. (Jchiyama, my assistant, 

 I am indebted for much painstaking photographic work.
