Among the anadromous fish the salmon is now that of the 
greatest consequence; but it is asserted that in the tidal 
portion of the river the value of the shad and twaite, in times 
gone by, equalled if it did not surpass that of the salmon : 
while in the upper waters Randall remarks that the lamprey 
fishing was that which was most thought of. As, however, 
only a certain number of fish can be accommodated in a river 
it becomes desirable to ascertain where that limit might be 
fixed. In considering such a question it has to be remembered 
that, excluding the eels, we have two classes of fish to deal 
with: the residents, which permanently remain and feed there, 
and the anadromous forms, the majority of which merely enter 
fresh water for breeding purposes, and most of which do not 
feed there, consequently a far larger number could be provided 
for than if they were rapacious kinds. It is, of course, very 
desirable, could steps be taken in order to prevent any undue 
capture from one portion of a river which would be detri- 
mental to the other riparian proprietors, or cause too great 
depletion to the stock present, which would injure the rights 
of the fish-consuming public. The naturalist has to draw 
attention to salmon being bred in the upper portions of rivers, 
and that it is there that artificial cultivation could be best 
carried on. It would be hardly just to the upper proprietors, 
who have had all the trouble and gone to a great portion of 
the expense, for the foregoing purpose, if such slaughter were 
permitted in the lower reaches of the river, that the upper 
proprietors merely see them during the breeding season when
