Another interesting result may be noticed in connexion with this Compensation Pond. The original streamlet, like most others, was naturally stocked with small "burn-trout," which never exceeded a few ounces in weight, as their ultimate term of growth. But, in consequence of the formation above referred to, and the great increase of their productive feeding-ground, and tranquil places for repose and play, these tiny creatures have, in some instances, attained to an enormous size. We lately examined one which weighed six pounds. It was not a sea-trout, but a common fresh-water one—Salmo fario. This strongly exemplifies the conformable nature of fishes; that is, their power of adaptation to a change of external circumstances. It is as if a small Shetland pony, by being turned into a clover field, could be expanded into the gigantic dimensions of a brewer's horse.
