to produce a hybrid of the salmon and sea-trout, and is very- 

 sanguine of success. The object is to have a new food fish 

 which will be in fine condition and seasonable just at the 

 time when the salmon and sea-trout are out of season and un- 

 eatable. 



Supposing the problem to be solved in regard to the reten- 

 tion of salmon and sea-trout in inclosed salt-water basins, the 

 question still remains as to the extent to which either will 

 thrive if permanently penned up in large fresh-water lakes, 

 and cut off from communication with the sea. It is not at all 

 improbable, however, that in the great lakes of our Northern 

 border this feat may be accomplished, especially as many ex- 

 perienced fishermen are of the opinion that the Lake Ontario 

 salmon, such as are bred at Mr. Wilmot's establishment at 

 Newcastle, are exclusively lacustrine. Should it be possible 

 to stock Lake Superior, Lake Michigan, Lake Huron, and Lake 

 Erie with salmon in addition to other food fishes, a very 

 great benefit will be conferred upon the adjacent states. 2^4,

CAPTURE OF RHINE SALMON IN HOLLAND. 



The German fish-culturists resident upon the upper waters 

 of the Rhine have lately been greatly aggrieved by the ac- 

 tion of the Dutch in catching the salmon bred by them while 

 in the lower waters of that river, and on their way from the 

 ocean to their spawning beds. This has been the subject of 

 a memorial on the part of the German Fischerei-Verein to the 

 society for promoting fresh-water fisheries in Holland, and a 

 rejoinder on the part of the latter body has lately made its 

 appearance. In this it is remarked that the matter in ques- 

 tion can not be judged except after due examination on the 

 spot, and that no importance should be attached to the im- 

 pressions of the gentlemen of the Fischerei-Verein, as they 

 have not themselves examined the method of fishing in Hol- 

 land, and the difficulties that this interest has to struggle with.

It is also maintained by the Dutch society that a residence on 

 the border gives the right to the inhabitants to appropriate 

 such a gift of nature ; and the fact that parties living on the 

 higher waters might secure a larger supply if those lower 

 down did not exercise their rights has nothing whatever to
