he red-throat
trout. I should think, from the description given in the report of the
Commission of Fisheries, Game, and Forests for the State of New York,
that it would do well in many of our waters. There are many varieties of
this species of trout. The common name of them all is _Salmo mykiss_,
the black-spotted trout of the Rocky Mountains. The cut-throat trout
proper, so called from the red colour of its throat, is simply S.
mykiss, but there are many varieties described. Among these are the
Columbia River trout (_S. mykiss_, var. _clarkii_), the Lake Tahoe trout
(_S. mykiss_, var. _henshawi_), the Rio Grande trout (_S. mykiss_, var.
_spilurus_), and the Colorado River trout (_S. mykiss_, var.
_pleuriticus_). As these names show, the black-spotted trout has a very
wide range and is found in what are totally different climates. I should
very much like to see the cut-throat and the Columbia River varieties
tried in our waters, particularly the former, as they would probably
succeed in waters which are too cold for the rainbow, and might very
likely thrive where our own trout (_S. fario_) is not a success. As it
is found in climates which vary so much as do Alaska and California, it
would probably be easy to find one variety, if not two or three, which
would thrive in England. It is a particularly fine trout, and the
ordinary maximum weight is five or six pounds, though some of the
varieties grow much larger.

Char, proper, are not at all satisfactory fish to rear. They are very
delicate, and require much more care and attention than do any of the
fish I have already described. From the very first period of their
coming under the care of the amateur fish culturist, that is to say,
from the ova, just before hatching out, till they are yearlings, the
mortality among them will be much greater than in the case of any of the
trout.

The two kinds of char, most commonly to be obtained by the amateur, are
the Alpine and the Windermere char. The ova of these fish will be
received shortly before they are ready to hatch out, as was the case
with the trout ova. The amateur's difficulties will, however, begin
almost at once, for in the act of hatching out considerable mortality
among the char often occurs. Trout almost invariably emerge from the egg
tail first. As soon as the tail is free the little fish begins to move
it rapidly, using it as a propeller with which to swim about and thus
soon works completely out of the egg. Occ
