“ Pigs and mules seem to be the only exception, thriving here as in other parts of the West Indies; and toads are most disgustingly numerous. Such a port as this, however, is entirely unsuited to be the centre of a great trade; and, accordingly, the intercourse between the two seas is already chiefly removed to Chagres. But the harbour to seaward is not there equal to what might be expected from the river which it receives and discharges. A ledge of rock runs across its mouth, with not more than fifteen feet water in the deepest places, and in many rising even to the surface. ”
