shore.

After walking for twenty minutes, the four castaways were suddenly
brought to a standstill by the sight of foaming billows close to their
feet. The solid ground ended here. They found themselves at the extremity
of a sharp point on which the sea broke furiously.

"It is a promontory," said the sailor; "we must retrace our steps,
holding towards the right, and we shall thus gain the mainland."

"But if he is there," said Neb, pointing to the ocean, whose waves shone
of a snowy white in the darkness. "Well, let us call again," and all
uniting their voices, they gave a vigorous shout, but there came no reply.
They waited for a lull, then began again; still no reply.

The castaways accordingly returned, following the opposite side of the
promontory, over a soil equally sandy and rugged. However, Pencroft
observed that the shore was more equal, that the ground rose, and he
declared that it was joined by a long slope to a hill, whose massive front
he thought that he could see looming indistinctly through the mist. The
birds were less numerous on this part of the shore; the sea was also less
tumultuous, and they observed that the agitation of the waves was
diminished. The noise of the surf was scarcely heard. This side of the
promontory evidently formed a semicircular bay, which the sharp point
sheltered from the breakers of the open sea. But to follow this direction
was to go south, exactly opposite to that part of the coast where Harding
might have landed. After a walk of a mile and a half, the shore presented
no curve which would permit them to return to the north. This promontory,
of which they had turned the point, must be attached to the mainland. The
castaways, although their strength was nearly exhausted, still marched
