A more tremendous burst of thunder than any yet experienced dwarfed all other sounds for an appreciable time. The American scrambled up, almost at her feet, and stood beside her. Stampa came quick on his heels, moving with a lightness and accuracy of foothold amazing in one so lame.

“Just me, Miss Wynton. Sorry if I have frightened you, but our old friend here was insistent that we should hurry. I have been tracking you since nine o’clock.”

Spencer’s words were nonchalantly polite. He even raised his cap, though the fury of the ice laden blast might well have excused this formal act of courtesy. Helen was still blushing so painfully that she became angry with herself, and her voice was hardly under control. Nevertheless, she managed to say:

“How kind and thoughtful of you! I am all right, as you see. Mr. Bower and the guide were able to bring me here before the storm broke. We happened to be standing near the door, watching the lightning. When I caught a glimpse of you I was so stupidly startled that I screamed and almost fell into Mr. Bower’s arms.”

Put in that way, it did not sound so distressing. And Spencer had no desire to add further difficulties to a situation already awkward.

“Guess you scared me too,” he said. “I suppose, now we are at the hut, Stampa will not object to my waiting five minutes or so before we start for home.”

“Surely you will lunch with us. Everything is set out on the table, and we have food enough for a regiment.”

“You would need it if you remained here another couple of hours, Miss Wynton. Stampa tells me that a first rate guxe, which is Swiss for a blizzard, I believe, is blowing up. This thunder storm is the preliminary to a heavy downfall of snow. That is why I came. If we are not off the glacier before two o’clock, it will become impassable till a lot of the snow melts.”

“What is that you are saying?” demanded Bower bruskly. Helen and the two men had reached the level of the cabane; but Stampa, thinking they would all enter, kept in the rear, “If that fairy tale accounts for your errand, you are on a wild goose chase, Mr. Spencer.”

He had not heard the American’s words clearly; but he gathered sufficient to account for the younger man’s motive in following them, and was furiously annoyed by this unlooked for interruption. He had no syllable of thanks for a friendly action. Though no small risk attended the crossing of the Forno during a gale, it was evident he strongly resented the presence of both Spencer and the guide.
