He dug five days, and found nothing solid.

On the sixth, being now at the bottom the ship, he struck his spade against something hard and heavy.

On inspection it looked like ore, but of what metal he could not tell; it was as black as a coal. He threw this on one side, and found nothing more; but the next day he turned up a smaller fragment, which he took home and cleaned with lime juice. It came out bright in places like silver.

This discovery threw light on the other. The piece of black ore, weighing about seven pounds, was in reality silver coin, that a century of submersion had reduced to the very appearance it wore before it ever went into the furnace.

He dug with fresh energy on this discovery, but found nothing more in the ship that day.
