or other of these trouts turning up in lakes where their pres- 
ence was unsuspected. It is, therefore, not unlikely, when 
their geographical distributions are better worked out, that 
this seeming partiality to certain waters may, after all, be 
more apparent than real. Further, it appears that their 
claims to be considered distinct species, rest altogether on cer- 
tain minor details of structure and coloring in each, which, 
however, have been further abridged by late researches. 
I therefore—and for other reasons—believe all lake trouts 
to be non-migratory, and to partake of peculiarities produced 
by habitat. For example, the Seneca and Canandaigua lake 
trouts are far more beautiful and finer flavored than the Ca- 
yuga Lake trout. The reason may be that the two former 
lakes are more profound and of mineral bottom, while the 
latter is shallow, with vegetable bottom. These lake trouts 
are gray-bodied, more or less clouded according to age (the 
young only being clouded), and they are further marked 
with vermicular tracery, and have fins placed like those of 
the salmon, but not the same shape. They are fork-tailed, 
but not so finely lined in all their proportions. The trout 
of Moosehead Lake and of a few lakes in New Brunswick 
are said to be the best for the table. They are scarce, and 
are never found south of the Boston fish markets. 
The namaycush is one exception to all other lake trouts, 
being what is termed, on page 265, the Mackinaw trout, its 
habitat being Lake Superior. This fish is supposed by nat- 
uralists to be a distinct family of lake trout. It is larger 
than any other lake trout, and a more delicate and succulent 
fish than any other confinies, except the siscowet and those 
of Maine and New Brunswick. 
The namaycush is generally taken in winter through the 
ice by hand-lines; for it would be superfluous to troll for 
him in summer in fifteen hundred feet depth of water, as 
there is no summer market for him, and the angler can find 
abundant sport more attractive.
