therefore, in utilising the remainder as food. The same 
argument might be urged against the eating of eggs or 
the eating of lambs, and the same reply might be given. 
But the world has long since made up its mind to go on 
eating eggs and lamb, and the reasons which justify it 
in doing so justify it still more in eating fish fry. 
‘““There is one argument urged against this view. 
which, however, requires consideration. If, it is asked, 
it be unnecessary to preserve the fry of sea fish, why is 
it necessary to preserve the fry of salmon? ‘The answer 
to the question may, we believe, be found in the distinc- 
tive habits of salmon and sea fish. Salmon are fish 
which migrate to and from river and sea. Sea fish are 
fish which live in the ocean. It is obviously possible 
for man to place some obstruction across a narrow 
channel in order to stop all or nearly all the salmon in 
their migration. But it is impossible by any device to 
surround or capture all the fish in the ocean. Salmon 
can be intercepted like the traffic which passes along a 
street. Sea fish can no more be intercepted than the 
traffic which crosses a plain. There is nothing easier 
than to place a turnpike gate across a road and to force 
all vehicles passing along it to pay toll. But a turnpike 
gate on a broad plain would be of no use. Nearly every 
carriage would pass it on one side or the other. 
‘‘ This example seems to us exactly to illustrate the 
distinction between a fish like a salmon frequenting a 
narrow channel during one portion of the year and sea 
fish which pass the whole of their life in the sea. 
Whenever the habits of any fish compel it to live 
throughout the year in a confined area to which man 
has access, or to pass once or more in any year into
