[Footnote 19: The neighborhood of Carthage, the sea, the
land, and the rivers, are changed almost as much as the
works of man. The isthmus, or neck of the city, is now
confounded with the continent; the harbor is a dry plain;
and the lake, or stagnum, no more than a morass, with six or
seven feet water in the mid-channel. See D'Anville,
(Geographie Ancienne, tom. iii. p. 82,) Shaw, (Travels, p.
77 - 84,) Marmol, (Description de l'Afrique, tom. ii. p.
465,) and Thuanus, (lviii. 12, tom. iii. p. 334.)]
