But Chayne bethought him of another day long ago, when a lad had burst into the hotel at Zermatt and told with no more acceptance for his story of an avalanche which he had seen fall from the very summit of the Matterhorn. Chayne looked at his watch. It was just four o'clock.

"There has been an accident," he said. "We must hurry."

CHAPTER XXIV

THE BRENVA RIDGE

The peasant was right. He had seen a man waving a signal of distress on the slopes of Mont Blanc above the great buttress. And this is how the signal came to be waved.

An hour before Chayne and Sylvia set out from Chamonix to cross the Col du Géant, and while it was yet quite dark, a spark glowed suddenly on an island of rocks set in the great white waste of the Brenva glacier. The spark was a fire lit by Pierre Delouvain. For Garratt Skinner's party had camped upon those rocks. The morning was cold, and one by one the porters, Garratt Skinner, and Walter Hine, gathered about the blaze. Overhead the stars glittered in a clear, dark sky. It was very still; no sound was heard at all but the movement in the camp; even on the glacier a thousand feet below, where all night long the avalanches had thundered, in the frost of the early morning there was silence.

Garratt Skinner looked upward.

"We shall have a good day," he said; and then he looked quickly toward
Walter Hine. "How did you sleep, Wallie?"

"Very little. The avalanches kept me awake. Besides, I slipped and fell a hundred times at the corner of the path," he said, with a shiver. "A hundred times I felt emptiness beneath my feet."

He referred to a mishap of the day before. On the way to the gîte after the chalets and the wood are left behind, a little path leads along the rocks of the Mont de la Brenva high above the glacier. There are one or two awkward corners to pass where rough footsteps have been hewn in the rock. At one of these corners Walter Hine had slipped. His side struck the step; he would have dropped to the glacier, but Garratt Skinner had suddenly reached out a hand and saved him.
