they have been successfully introduced into 

 lakes of Maine, New York, and other States, 

 and even as far south as North Carolina. 



The California salmon-hatchery, on the Mc- 

 Cloud river, was established in 1872, under the 

 direction of Livingston Stone, who has made

it the greatest station of the kind in existence. Washington. 

 The native salmon are stopped in their ascent 

 of the river by a dam near the hatchery, and 

 they congregate in vast numbers. In 1877 Mr. 

 Stone built the salmon-hatching establishment 

 on Clackamas river, Oregon, and in 1879 the 

 McCloud river trout-pond station was estab- 

 lished for treating eggs of the rainbow-trout. 

 Mr. Stone has summarized the work of the 

 salmon station in the following words: "In 

 the eleven years since the salmon - breeding 

 station has been in operation, 67,000,000 eggs 

 have been taken, most of which have been dis- 

 tributed in the various States of the Union. 

 Several millions, however, have been sent to 

 foreign countries, including Germany, France, 



Great Britain, Denmark, Russia, Belgium. Hol- 

 land, Canada, New Zealand, Australia, and the 

 Sandwich Islands. About 15,000,000 have 

 been hatched at the station, and the young 

 fish placed in the McCloud and other tributaries 

 of the Sacramento river. So great have been 

 the benefits of this re- 

 stocking of the Sacra- 

 mento, that the statistics 

 of the salmon -fisheries 

 on the Sacramento show 

 that the annual salmon- 

 catch of the river has in- 

 creased 5,000,000 pounds 

 during the past few 

 years." 



The principal shad - 

 hatching station of the 

 United States is in the 

 Armory, Army Square, 

 This building now has all the 

 modern appliances for the work, and can ac- 

 commodate an unlimited number of eggs. 

 Nearly 50,000,000 were received there in one 

 year. Eggs are received from small camps 

 from fifty to one hundred miles away, and the 

 fry are shipped in cars constructed for fish- 

 transportation. The station near Havre de 

 Grace, in the lower waters of the Susquehanna 

 river, is also important, and it has the advan- 

 tage of a large pool in which shad may be con- 

 fined until their eggs are ripe. Fully 70,000,000 

 eggs of shad have been hatched in a single year 

 at all the stations of the commission. Instances 

 of great improvement might be cited in con- 

 nection with nearly every shad-river in the
