 No food, however, has been at any time found in its 

 stomach after entering our rivers. There may be one 

 obstacle, however, to its introduction into European rivers ; 

 this is, that its spawn hatches out in the incredibly short 

 time of fifty-two hours. It was so proved on the Connecti-

A great fuss has been made about stocking the Thames 

 with salmon. Hundreds of pounds have been spent, and
