"On, on," I cried, for we were past the need for silence, and when I looked again, the kindly fog had swallowed up the van of the party.

I turned and gazed back, and there I saw a strange sight. A dozen men or more had come to the edge of the trees on the hill-side. They were quite near, not two hundred yards distant, and I saw them clearly. They carried bows or muskets, but none offered to use them. They were tall fellows, but lighter in the colour than any Indians I had seen. Indeed, they were as fair as many an Englishman, and their slim, golden-brown bodies were not painted in the maniac fashion of the Cherokees. They stood stock still, watching us with a dreadful impassivity which was more frightening to me than violence. Then I, too, was overtaken by the grey screen.

"Will they follow?" I asked Shalah.

"I do not think so. They are not hill-men, and fear the high places where the gods smoke. Further-more, there is no need."

"We have escaped, then?" I asked, with a great relief in my voice.

"Say rather we have been shepherded by them into a fold. They will find us when they desire us."

It was a perturbing thought, but at any rate we were safe for the moment, and I resolved to say nothing to alarm the others. We overtook them presently, and Shalah became our guide. Not that more guiding was needed than Ringan or I could have given, for the lift of the ground gave us our direction, and there was the sound of a falling stream. To an upland-bred man mist is little of a hindrance, unless on a featureless moor.

Ever as we jogged upward the air grew colder. Rain was blowing in our teeth, and the ferny grass and juniper clumps dripped with wet. Almost it might have been the Pentlands or the high mosses between Douglas Water and Clyde. To us coming fresh from the torrid plains it was bitter weather, and I feared for Elspeth, who was thinly clad for the hill-tops. Ringan seemed to feel the cold the worst of us, for he had spent his days in the hot seas of the south. He put his horse-blanket over his shoulders, and cut a comical figure with his red face peeping from its folds.

"Lord," he would cry, "I wish I was in the Dry Tortugas or snug in the beach-house at the Isle o' Pines. This minds me painfully of my young days, when I ran in a ragged kilt in the cold heather of Cruachan. I must be getting an old man, Andrew, for I never thought the hills could freeze my blood."

Suddenly the fog lightened a little, the slope ceased, and we had that gust of freer air which means the top of the pass. My head was less dizzy now, and I had a momentary gladness that at any rate we had done part of what we set out to do.
