420 ANNUAL RECORD OF SCIENCE AND INDUSTRY. 



It is well known that salmon formerly abounded in Lake 

 Champlain and its tributaries on both sides, and, with a 

 view of determining whether the same condition of things 

 can be restored to these waters, this experiment has been 

 made. 



DISTRIBUTION OF TROUT EGGS FROM TASMANIA TO THE 



NEIGHBORING COLONIES. 



The Society of Arts refers to an official report in regard 

 to the acclimatization of trout in Tasmania, which states 

 that in 1873 a total distribution of 4050 trout e2;s was 

 made from the rivers of that country to the neighboring col- 

 onics ; 800 of these were sea trout, the rest being those of 

 the brown trout. 23 A, June 11, 1875, 664. 



IMPORTATION OF THE GOURAMI INTO PARIS. 



A Paris journal announces the arrival in that city, in No- 

 vember last, of forty-eight gourami fish, sent to M. Carbon- 

 nier, the well-known dealer in aquarial supplies, and who has 

 made a specialty of importing fish of this character. This 

 gentleman now has seventy specimens in all, in thriving con- 

 dition. The fish is warmly recommended for introduction 

 into the hotter parts of the United States, especially South 

 Carolina, Western Florida, and other sections where ice and 

 frost are unknown. 



Their special merit consists in their being fresh-water fish, 

 of large size and great excellence of flesh, that feed entire- 

 ly on vegetable matter, so that if placed in a pond with plen- 

 ty of aquatic plants around them they will live and thrive 

 without requiring any artificial means. 10 B, Dec, 1874,770. 



FRENCH METHOD OF OYSTER CULTURE. 



M. Crugny announces in Les Mondes that, after ten years 

 of groping in the dark in the treatment of the great oyster 

 banks of France, especially of Arcachon, these have entered 

 upon a career of fertility so prodigious that Arcachon alone 

 will soon be able to furnish oysters for the whole world, and at 

 prices much lower than those which at present prevail. It is 

 well known, according to Crugny, that each oyster produces, 

 every year, spat sufficient to furnish 4,000,000 of young, but 

 that innumerable sources of destruction greatly reduce the
