Aloft all sharp grey stone: below, wherever the salt water had reached, a mass of dark clinging weed: while beyond, as though set in a dark frame, was a soft glimpse of blue sky and snow-white seabirds.
"There is nothing so grand as that in Cornwall, Doctor," said Halbert.
"Can we pass under it, Mr.Barker ?" said Alice.

"I should like to go through; we have been into none of the caves yet." "Oh, yes!" said George Barker.

"You may go through for the next two hours.

The tide has not turned yet." "I'll volunteer first," said the Doctor, "and if there's anything worth seeing beyond, I'll come for you." It was, as I said, a thin wall of granite, which ran out from the rest of the hill, seaward, and was pierced by a tall arch; the blocks which had formerly filled the void now lay weed-grown, half buried in sand, forming a slippery threshold.

Over these the Doctor climbed and looked beyond.
A little sandy cove, reef-bound, like those they had seen before, lay under the dark cliffs; and on a water-washed rock, not a hundred yards from him, stood the man they had seen on the downs above, looking steadily seaward.
The Doctor slipped over the rocks like an otter, and approached the man across the smooth sand, unheard in the thunder of the surf.
