To enable tke public to form some idea of tke extent of public fisk- 

 culture witkin the limits of the United States, a brief description of 

 the operations of several of the larger stations operated by the IT. S. 

 Fish Commission is given. 



The hatchery at North ville, Mich., under the direction of Mr. Frank 

 N. Clark, passed into the hands of the U. S. Fish Commission in 1880, and 

 is now one of the most important stations for salmonidse in the world. 

 It is provided with natural and artificial ponds in which brook-trout,, 

 rainbow-trout, land-locked salmon and lake-trout, are kept for breeding 

 purposes. In addition to tke eggs obtained from these ponds, many 

 millions of eggs of the whitefisk, lake-trout, and wall-eyed pike are ob- 

 tained in the waters of Lake Erie, and forwarded to Nortkville to be 

 hatched and distributed. During the season of 1882-'S3, 70,950,000 eggs 

 of the salmonidae were handled at this hatchery, a large percentage of 

 which were hatched and distributed to different waters. A large refri- 

 gerator is being put in readiness for next season's work, when it is 

 expected that fully 500,000,000 eggs of the wkitefisk alone will be 

 hatched. 



The hatcheries at Bucksport and Grand Lake Stream are both under 

 the superintendence of Mr. Charles G. Atkins. The former of these is 

 provided with ponds in which salmon, purchased from the fiskermen of 

 the Penobscot Biver, in May, are confined till November, at which time 

 the eggs are taken and tke fish liberated. At Grand Lake Stream, 

 wkere tke land-locked salmon are hatched, the eggs are obtained from 

 the wild fisk which, when attempting to ascend to their natural spawn- 

 ing grounds, are turned aside into inclosures of netting, where they are 

 retained until all of the eggs have been secured. There were secured 

 at these two stations, during the past season, 3,675,000 eggs of these 

 species for distribution to different parts of the United States.
