"I mean that I believe Monsieur Lattery has made the first passage of the Col des Nantillons from the east," he said, with a peculiar solemnity. "I think we must look for them on the western side of the pass, in the crevasses of the Glacier des Nantillons."

"Surely not," cried Chayne. True, the Glacier des Nantillons in places was steep. True, there were the séracs—those great slabs and pinnacles of ice set up on end and tottering, high above, where the glacier curved over a brow of rock and broke—one of them might have fallen. But Lattery and he had so often ascended and descended that glacier on the way to the Charmoz and the Grépon and the Plan. He could not believe his friend had come to harm that way.

Michel, however, clung to his opinion.

"The worst part of the climb was over," he argued. "The very worst pitch, monsieur, is at the very beginning when you leave the glacier, and then it is very bad again half way up when you descend into a gully; but Monsieur Lattery was very safe on rock, and having got so high, I think he would have climbed the last rocks with his guide."

Michel spoke with so much certainty that even in the face of his telegram, in the face of the story which Jules had told, hope sprang up within Chayne's heart.

"Then he may be still up there on some ledge. He would surely not have slipped on the Glacier des Nantillons."

That hope, however, was not shared by Michel Revailloud.

"There is very little snow this year," he said. "The glaciers are uncovered as I have never seen them in all my life. Everywhere it is ice, ice, ice. Monsieur Lattery had only one guide with him and he was not so sure on ice. I am afraid, monsieur, that he slipped out of his steps on the Glacier des Nantillons."

"And dragged his guide with him?" exclaimed Chayne. His heart rather than his judgment protested against the argument. It seemed to him disloyal to believe it. A man should not slip from his steps on the Glacier des Nantillons. He turned toward the door.

"Very well," he said. "Send three guides up the Mer de Glace. We will go up to the Glacier des Nantillons."
