The port of Nelkundah, which, as we have already remarked, was the limit of our author's personal knowledge, was a place of very great trade; it was much frequented, principally on account of the betel and pepper, which were procured there on very reasonable terms: the pepper is distinguished, in the list of its imports, as the pepper of Cottonara. Besides this article and betel, the only exports were, pearls, ivory, silks, spikenard, precious stones, and tortoise-shell; the imports were chiefly specie, topazes, cloth, stibium, coral, glass, brass, tin, lead, wine, corn, &c. The ports to the south of Nelkundah are described in a cursory manner in the Periplus; they were frequented principally by the country ships, which carried on a lucrative trade between them and the ports in the north of India. The exports of the island of Trapobane, or Ceylon, are particularized as consisting chiefly of pearls, gems, tortoise-shells, and muslins: cinnamon is not named; an almost decisive proof, if other proof were wanting, that the author of the Periplus had never visited this island. That trading voyages were carried on by the natives from the southern ports of India, not only to the northern ports of the western side of that country, but also to the eastern ports in the Bay of Bengal, and to the farther peninsula itself, we are expressly informed, as our author mentions vessels of great bulk adapted to the voyages made to the Ganges and the Golden Chersonese, in contradistinction to other and smaller vessels employed in the voyages to Limurike.
