DO SALMON FEED IN FRESH WATERS? 



The question has frequently been started as to whether the 

 salmon feeds in fresh waters, and careful examination of many 

 specimens in England has failed to reveal any thing in their 

 stomachs. During the past summer Mr. Charles G. Atkins, 

 who has penned up six hundred salmon at Bucksport, Maine, 

 with a view of keeping them until their spawning season, 

 was careful to save the stomachs of all the fish that died in 

 his* charge, amounting to twenty or thirty in all. They were 

 principally taken below Bucksport, in Penobscot Bay, in 

 weirs, and brought alive to his establishment. The stomachs 

 of these fish were submitted to Professor Sidney J.Smith, of 

 New Haven, our leading carcinologist, in order that he might 

 ascertain whether they contained remains of Crustacea or 

 other marine animals, and after diligent investigation he re- 

 ports that nothing of the kind can be found. In the in- 

 testines of one specimen two small bits, of wood were met 

 with. 



SALMON FISHERIES IN THE COLUMBIA RIVER. 



Some idea of the economical value of streams abounding 

 in salmon may be gathered from the statistics of the salmon 

 fishery of the Columbia River during the past season, which 

 lasted from April 1 to the end of July. The number offish 

 consumed fresh, on the river, and even exported to other 

 parts along the coast, can not be ascertained with perfect 

 correctness ; but the San Francisco Bulletin gives the amount 

 of the catch of salmon by six establishments for the purpose 

 of canning and salting. From this paper w r e learn that dur- 

 ing the above-named period 1 70,000 salmon w r ere canned, 

 weighing, when dressed, 2,700,000 pounds, and filling 26,250 

 boxes of 48 pounds each, their wholesale value amounting 

 to $242,000. The pickled salmon amounted to 162,000, 

 weighing, when dressed, 2,600,000 pounds, and filling 13,000 

 barrels of 200 pounds each, and worth $117,000. The total 

 number of salmon taken in four months on the Lower Co- 

 lumbia, for canning and curing purposes, thus amounted to 

 332,000, weighing 5,300,000 pounds, and worth $359,000. 

 The canned salmon of the Columbia River are rapidly find- 

 ing their way to, and a ready market in, all parts of the
