Whatever falls into the pool is carried under the ground and appears again in the sea, which is about a half a mile distant from the pool. So, then, the story that comes from the island lying off the Libyan coast is like the truth, too.

Another story is told by the Carthaginians. There is a place in Libya [17,25] (nation), AfricaLibya, they say, where men live beyond the Pillars of Heracles; they come here and unload their cargo; then, having laid it in order along the beach, they go aboard their ships and light a smoking fire. The people of the country see the smoke, and, coming to the sea, they lay down gold to pay for the cargo, and withdraw from the wares.

Then the Carthaginians disembark and examine the gold; if it seems to them a fair price for their cargo, they take it and go away; but if not, they go back aboard and wait, and the people come back and add more gold until the sailors are satisfied.
