"Whilst I resided in Philadelphia, in 1782, and 1783, I discovered that the shad brought to market from the Scuylkill were very superiour in flavour and firmness to those taken in the Delaware, which must proceed from their food in that river, previous to their going to the sea; as they are taken by the nets of the fishermen, before they are six hours in that river, on their return. I cannot think it a romantic idea, that the waters are impregnated with certain particles, on which they have been accustomed to feed; which is sufficient to allure them to where they were originally spawned; or that they are piloted there by some of the old fry. This idea will not appear improbable, when we consider the general laws which seem to control the whole finny tribe; and what would be the consequence should they be thrown down? The cod-fish which occupy the banks of Newfoundland, between the latitudes of 41 and 45, are very different, and are kept so distinct, and are so similar on the respective banks, that a man acquainted with that fishery will separate those caught on one bank from those of another, with as much ease as we separate the apple from the pear.
