A trader who goes from place to place, or along the streets of a town, selling the goods which he carries with him.
It is perhaps not essential to the idea, but is generally understood from the word, that a hawker is to be one who not only carries goods for sale, but seeks for purchasers, either by outcry, which some lexicographers conceive as intimated by the derivation of the word, or by attracting notice and attention to them, as goods for sale, by an actual exhibition or exposure of them, by placards or labels, or by a conventional signal, like the sound of a horn, for the sale of fish.
