be noted that in 1878 the Government hatched and liberated 

 salmon and trout in the prin cipal rivers in the north-eastern part 

 of Japan and Hokkaido and afterwards the same process was 

 frequently repeated in lakes and rivers at home. 



The Hokkaido Administration headed the others in establish- 

 ing Government grounds with a view to the encouragement of 

 such practices. 



The result was the establishment of private hatching grounds. 

 In the north-eastern parts of Honshu, we observe the appearance 

 of hatching grounds both official (expenses defrayed by local 

 expenses) and private. 



The hatching ground is chiefly constructed after the model 

 of the Buxford hatching ground, in the State of Maine, U.S.A. 

 while the method with fish eggs is the dry method of fertilization, 

 and the hatching vessel of Mr. Atkin's is adopted. The latest 

 favourable results have been obtained in the Towada lake, Akita 

 prefecture. In 1884, the lake was altogether destitute of any 

 fish, but a certain Wanai Sadayuki opened the waterfall of the 

 Nenorogawa, which forms an exit to the lake, with a view to 

 make a path for fish, and at the same time, the hatching ground 

 was established. During the following years, the eggs of trout 

 were obtained from the Chugiiji lake, Nikko which were hatched 

 and liberated. Subsequently the fresh water salmon produced in 

 Hokkaido were hatched and liberated three or four years ago, 

 while the parental fish of the same lake were employed for the 

 purpose of taking eggs and for hatching and liberation. 



The work has attained such a degree of success that eggs are 

 now furnished to other places and the industry attracts the 

 attention of foreigners. In such lakes as the Chuguji, Nilcko 

 and Ashi Hakone, trout are hatched and liberated by the
