to think that in the
case of a pond in the south, even when it is supplied by a good stream,
the rainbow is the better fish with which to stock. I have been led to
believe this, partly through my own experience, and partly on account of
the opinion of Mr. Senior, for I consider his opinion on such a matter
of the greatest possible value.

Another point about the rainbow, which in many cases will recommend it
particularly to the amateur, is that though of course an abundant supply
of water is an advantage, it may be reared with a smaller supply.

A fish which has been very freely introduced into British waters is the
American brook-trout (_Salvelinus fontinalis_). Though this fish is not
really a trout but a char I have included it among trout, because it is
so very generally known to fishermen as the American brook-trout. The
_fontinalis_, as it is commonly called by fish culturists, is a very
satisfactory fish to rear artificially, but there seems to be some doubt
as to its suitability to British waters. It grows to a considerable size
under favourable conditions, and is one of the best of table fishes. It
is, however, undoubtedly one of the worst of cannibals among sporting
fishes, and does not apparently rise freely to the fly when about two
years old and older.

The spawning season is extended over an even longer period than that of
our own brown trout, beginning, in its native country, in October, and
sometimes lasting till March. It shows a very marked tendency, at any
rate in America, to go down to the sea, and in some parts of Canada is
called a sea-trout. The fish are easy to rear, but I should recommend
great caution with regard to their introduction into any waters in
England. The remarks and instructions which I gave with regard to the
common trout, apply also to the _fontinalis_, but I would lay particular
stress upon the necessity of separating the fish, as soon as some grow
larger than the rest. The only drawback to this fish, from the fish
culturist's point of view, is that though a very free feeder, it is very
dainty, sometimes refusing a particular kind of food for no apparent
reason. As the spawning season is extended over such a considerable
period of time, it is obvious that the amateur will be able to obtain
the ova, ready to hatch out, during a similarly lengthy period.

A fish which I should very much like to see tried in England, is the
cut-throat trout (_Salmo mykiss_). It is also known as t
