of them ninety-six per cent hatched. The cost of production 

 was only $18.09 per thousand, and it is believed they can be 

 furnished hereafter at $8.00. 



With a fair start once gained, progress is rapid. In Ver- 

 mont, between 30,000 and 40,000 salmon-eggs have been put 

 into West River, the Winooski, and Williams River. In New 

 Hampshire, salmon-ova were placed in the Merrimac by Dr. 

 Fletcher as long ago as 1867, and should be heard from soon, 

 if alive. Land-locked salmon have been put into Newfound 

 Lake. In Maine, 28,000 salmon-spawn have been put into 

 the Androscoggin River, and fish- ways have been opened over 

 the dams at the Grand Lakes so that salmon can now ascend. 

 The first effort to stock the Connecticut River with salmon 

 was made in 1868, and large quantities of spawn have been 

 since put into it; also into the Pequonnock, Housatonic, 

 Shetauket, and Farmington Rivers, and tributaries of the 

 Quinnebaug. Land-locked salmon have been placed in nine 

 ponds or rivers of seven counties of Connecticut. Shad 

 have multiplied rapidly in the Connecticut under protection 

 and cultivation. The catch of 1871 was three times as large 

 as that of the previous year. In New York, a State hatch- 

 house has been established at Rochester, whose operations 

 have been wholly successful. Several thousands of spawn 

 have been disposed of to applicants. Salmon have been 

 placed in the Hudson, Genesee, and Delaware Rivers, and 

 trout and salmon-trout in many waters that were barren 

 before. A hatch-house has also been located at Central 

 Park, New York city. In New Jersey and Pennsylvania, 

 salmon-fry have been placed in the Delaware River, and 

 salmon-trout fry in the Susquehanna. California is not slack 

 in her efforts to preserve the fish of her valuable rivers from 

 extinction. She has commenced her work in season, and by 

 compelling thus opportunely the erection of fish- ways, where- 

 ever needed, will keep up her stock of fish to its natural 

 quota. Some 10,000 Eastern trout have been acclimated in 

 the waters of California, and are thriving. The trout species
