Filling the hollow in the ledge with the sea-water, we first tried to get fire enough about it to make the water boil.

This we found it impossible to do, and so had recourse to a plan suggested by Kit.

It was to get eight or ten stones about the size of the tin bumper, and heat them in the fire.

When red-hot, these were successively rolled into the water in the hollow, raising great clouds of steam, and soon causing it to boil furiously.

Continuing this stone-heating process for three or four hours, we succeeded in boiling away fully half a dozen pailfuls of water.
