8 FISH-CULTURAL: ASSOCIATION. 
fish that I have never fancied much, and am in greater doubts as 
to their value since reading the last report of the New York Fish 
Commission, which says: 
“A good deal is to be learned yet respecting temperature and 
other local conditions affecting fish. Till the past year not 
enough had been done in stocking with rainbow trout to war- 
rant a judgment of their ultimate success in the waters on the 
Atlantic side. Their time of spawning occurring at a different 
season from that of the native brook trout, it would not seem to 
be policy to plant them in waters inhabited by that fish. The 
protective seasons would need to be different, and inhabiting 
the same waters one kind might be taken often when the other 
was fished for, and thus unintended violations would be liable 
to.,occur. An obstacle’ to their ready ‘suctess in ‘Oun/wasene 
presents itself in the circumstance that at the season the fry are 
ready to plant, all-other fish are greedily feeding, and conse- 
quently a considerable share of the fry are liable to be nipped 
in the bud. This, however, may be avoided by providing places 
where the fry can be free from, the presence of * predaron, 
enemies till they are able to look after their own safety. 
“From the circumstance that they have not been readily found 
always in the second year, where the plants have been made, it 
has been surmised that they are a migratory fish—working their 
own way, as soon as they attain any considerable growth, down 
stream toward the ocean. Their disappearance, however, may 
be accounted for by the other ‘cause stated: Further €xperr 
ments will be necessary to solve all the problems connected 
with their establishment in the Eastern waters; but the prom- 
ise continues to be that they will prove themselves a fish of 
great value in stoclsing large Suse se whose temperature is too 
high for brook trout.’ 
An editorial note in Forrest AND STREAM of May rst, written 
by myself, says of the rainbow trout: 
“We would call attention to the paragraph in our notice of 
the report of the New York Fish Commission concerning these 
fish. It is beginning to be learned that they are migratory, and 
do not remain in brooks. We have never been much in favor 
of this fish, because we have known, what is not popularly known,
