It was a grey day, humid and still, and, being low tide, there seemed no fresh wind blowing in from the sea as usual. The children scrambled over the rocks, very happy and important at being, for once, left to their own devices, and they decided to make an expedition to a little sandy bay that can be reached from the shore at low tide, and to come back by a steep winding path up the cliffs which terminates in the coach road just above the village. They had not considered it necessary to confide their intention to Polly, who would certainly have objected. They reached the bay all right, paddled for a little time on the hard, smooth sand, and then set out to climb the path which winds in and out of the side of the cliff for all the world like a spiral staircase up to some nine hundred feet above the sea. This path is so narrow that travelers can only walk in Indian file. On the one side is the steep face of the heather-clad rock, on the other a sheer drop on to the rocks below.

When the children had climbed about a third of the way they found themselves enveloped in white mist—a mist so thick, and fine, and clinging, that you cannot see your own hand held before your face. It was no use to go down again; the tide had turned, and soon the sea would be lapping gently at the foot of the pathway. There was nothing for it but to go on slowly, carefully, step by step, feeling all the time for the rocks on the inner side; by and by the path would widen.

“Don’t be frightened, Viola,” said Basil cheerfully. “It’ll take us a goodish while, but a bit higher up we can walk together.”

“I’m not exactly frightened,” said Viola in a tremulous voice, “but I rather wish we hadn’t come.”

“So do I,” Basil answered fervently. “If I hadn’t been such a juggins I’d have looked up and seen the mist on those cliffs long ago. Probably you can’t see that there are any cliffs in the village now.”

On they toiled, slowly and painfully. It is really a most unpleasant mode of progression, walking sideways up a hill with your back against a very nubbly sort of wall.

“Hark!” cried Basil presently. “Didn’t you hear a call?”

The children paused, leant against the cliff, and listened breathlessly. Sure enough someone was calling. It sounded very muffled and far off; but it was plainly a man’s voice, and he was calling for help.

“Do you think it’s above or below?” Basil asked anxiously. “I can’t seem to tell in this fog.”

“It must be above, or we should have heard it before. Call out that we’re coming.”
