Mr Stoddart must feel neither anger nor surprise if we deliberately avoid not merely any discussion, but even any notice whatever, of theories or speculations, directly or collaterally referring to the breeding or propagation of fishes. We have not been, as the pages of Maga prove, unwatchful of what conjectural philosophy might propose, or ingenious experimentalism might exhibit. We hold some piscine opinions, so curious but so true, that if we could enunciate them in a language intelligible to fish (which ought to be the Finnish dialect,) the liveliest salmon in Norway could not execute summersets sufficiently numerous to express his astonishment at our knowledge. We could likewise put such puzzling objections to the most elaborate and seemingly satisfactory systems, as to demonstrate irrefragably that, in spite of every thing which every body has said about every variety of the _salmo_ race, nobody knows any thing certain as to the age Of OLD PARR. But, for one good reason, we shall be discreet and silent. Nobody cares a straw, or a horse-hair, or a thread of gut, whether Stoddart is overthrown, or Shaw is predominant,--nobody, whose sole and laudable object is to enjoy a day's good fishing. The great fact remains--the waters are full of fish. What matter is it whence the fins came or come? The question is not how they got into, but how they are to be taken out of the burn, the river, or the lake? It is not we who mean to go "Under the glassy, cool, translucent wave;" but up out of it we hope to draw many dozens of its peopling swarms. And we desire to learn from Mr Stoddart how best we may, by baits and guileful spells, reach and inveigle, them-- "In their obscured haunts of inmost bowers."
