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 the 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.
