So when I repeated: "And you saw something else, William?" he gave me a wicked, frightened leer, and shuffled off to feed the mules. Flattery, entreaties, threats left him unmoved; he never told me what the third thing was that he had seen behind the Hudson Mountains.
William had retired to mix up with his mules; I resumed my binoculars and my silent inspection of the great, smooth path left by the Graham Glacier when something or other exploded that vast mass of ice into vapor.
The arid plain wound out from the unknown country like a river, and I thought then, and think now, that when the glacier was blown into vapor the vapor descended in the most terrific rain the world has ever seen, and poured through the newly blasted mountain-gateway, sweeping the earth to bed-rock. To corroborate this theory, miles to the southward I could see the débris winding out across the land towards Wellman Bay, but as the terminal moraine of the vanished glacier formerly ended there I could not be certain that my theory was correct. Owing to the formation of the mountains I could not see more than half a mile into the unknown country. What I could see appeared to be nothing but the continuation of the glacier's path, scored out by the cloud-burst, and swept as smooth as a floor.
Sitting there, my heart beating heavily with excitement, I looked through the evening glow at the endless, pine-crowned mountain-wall with its giant's gateway pierced for me! And I thought of all the explorers and the unknown heroes—trappers, Indians, humble naturalists, perhaps—who had attempted to scale that sheer barricade and had died there or failed, beaten back from those eternal cliffs. Eternal? No! For the Eternal Himself had struck the rock, and it had sprung asunder, thundering obedience.
In the still evening air the smoke from the fire below mounted in a straight, slender pillar, like the smoke from those ancient altars builded before the first blood had been shed on earth.
The evening wind stirred the pines; a tiny spring brook made thin harmony among the rocks; a murmur came from the quiet camp. It was William adjuring his mules. In the deepening twilight I descended the hillock, stepping cautiously among the rocks.
Then, suddenly, as I stood outside the reddening ring of firelight, far in the depths of the unknown country, far behind the mountain-wall, a sound grew on the quiet air. William heard it and turned his face to the mountains. The sound faded to a vibration which was felt, not heard. Then once more I began to divine a vibration in the air, gathering in distant volume until it became a sound, lasting the space of a spoken word, fading to vibration, then silence.
Was it a cry?
I looked at William inquiringly. He had quietly fainted away.
I got him to the little brook and poked his head into the icy water, and after a while he sat up pluckily.
