Anglers might raise the cry that they require all the finny inhabitants of our waters for their own sport. It is scarcely necessary to go as deeply into the subject as mathematical-minded Mudie did to show that Nature's lavishness in the production of life would make such a contention unreasonable. He demonstrated that if all the fishes hatched were to live their full term, in twenty-four years their production power would convert into fish (two hundred to the solid foot) as much matter as there is contained in the whole solar system--sun, planets, and satellites! An "abundantly startling" result, as he says. To be well within the mark, ninety-nine out of every hundred fishes hatched must somehow perish during that stage when they are nothing but suitable morsels for the kingfisher, to be swallowed entire; and a portion of all this wasted food might very well go to sustain a few species, which would be beautiful ornaments of the waterside, and a perpetual delight to all lovers of rural nature, including anglers. It may be remarked in passing, that the waste of food, in the present disorganized state of nature, is not only in our streams. The introduction of one or more of these lovely foreign kingfishers would not certainly have the effect of hastening the decline of our native species; but indirectly it might bring about a contrary result--a subject to be touched on at the end of this paper. Practical naturalists may say that kingfishers would be far more difficult to procure than other birds, and that it would be almost impossible to convey them to England. That is a question it would be premature to discuss now; but if the attempt should ever be made, the difficulties would not perhaps be found insuperable. In all countries one hears of certain species of birds that they invariably die in captivity; but when the matter is closely looked into, one usually finds that improper treatment and not loss of liberty is the cause of death. Unquestionably it would be much more difficult to keep a kingfisher alive and healthy during a long sea-voyage than a common seed-eating bird; but the same may be said of woodpeckers, cuckoos, warblers, and, in fact, of any species that subsists in a state of nature on a particular kind of animal food. Still, when we find that even the excessively volatile humming-bird, which subsists on the minutest insects and the nectar of flowers, and seems to require unlimited space for the exercise of its energies, can be successfully kept confined for long periods and conveyed to distant countries, one would imagine that it would be hard to set a limit to what might be done in this direction. We do not want hard-billed birds only. We require, in the first place, variety; and, secondly, that every species introduced, when not of type unlike any native kind, as in the case of the pheasant, shall be superior in beauty, melody, or some other quality, to its British representative, or to the species which comes
