development of marine forms, and also impart instruction 
to those qualified to learn.- Inshort, anamply equipped 
college of biology, pisciculture and kindred branches of 
study, should be established upon the most liberal scale 
in a locality the natural advantages ot which would 
insure its most economical constructionand maintenance. 
Among the various branches of practicable effort that 
such an institution would facilitate may be mentioned 
the acquirement of knowledge as to the habits, mode of 
spawning of deep sea fishes, ‘and also the acclimatization 
of edible fish of warmer waters. The elimination of the 
migratory instinct in the land- locked salmon of Maine, 
in the Canadian Winninnish, and also in the fresh water 
smelt of our own and of other lands, suggests another. 
During the first third of the present century the streams 
running into Lake Ontario swarmed in their season 
with my yriads of salmon, farmers pitch-forked them upon 
the banks and sometimes at night their teams would 
kill them at the fords, the frichtened horses plunging 
through dense masses crowding in darkness over the 
shallows. The choking of the streams with nets soon 
made the salmon a reminiscence, and to this day it is 
disputed whether they journeyed from the deeps of the 
far distant sea, stemming the swift current and swifter 
rapids of the mighty St. Lawrence, or whether they 
were residents of the great lake itself. We know, 
however, that the migratory instinct has become 
dormant in many anadromous fish, and there is reason 
to believe that their permanent adaptation to fresh water 
has been effected by natural agencies operating through 
a brief period. 
If the swarming menhadden of our coast could be 
gradually replaced by a variety in which the wander- 
ing impulse was absent much would be gained, nor need 
it seem visionary to attempt its ultimate development 
into a valuable food fish by the constant addition of 
improved varieties obtained under culture. Although
