"And the air was stagnant,--dead. The atmosphere seemed to lie upon the body like the weight of sea on a diver who has ventured too far into its awful depths. What we usually call silence seems so only in relation to the din of ordinary experience. This was silence in the absolute, and it crushed the mind while it intensified the senses, bringing down the awful weight of inextinguishable fear. "I know that Nils and I stared towards each other in abject terror, listening to our quick, heavy breathing, that sounded to our acute senses like the fitful rush of waters. And the poor little dog we were leading justified our terror. The black oppression seemed to crush him even as it did us. He lay close on the ground, moaning feebly, and dragging himself painfully and slowly closer to Nils's feet. I think this exhibition of utter animal fear was the last touch, and must inevitably have blasted our reason--mine anyway; but just then, as we stood quaking on the bounds of madness, came a sound, so awful, so ghastly, so horrible, that it seemed to rouse us from the dead spell that was on us. "In the depth of the silence came a cry, beginning as a low, sorrowful moan, rising to a tremulous shriek, culminating in a yell that seemed to tear the night in sunder and rend the world as by a cataclysm. So fearful was it that I could not believe it had actual existence: it passed previous experience, the powers of belief, and for a moment I thought it the result of my own animal terror, an hallucination born of tottering reason. "A glance at Nils dispelled this thought in a flash. In the pale light of the high stars he was the embodiment of all possible human fear, quaking with an ague, his jaw fallen, his tongue out, his eyes protruding like those of a hanged man. Without a word we fled, the panic of fear giving us strength, and together, the little dog caught close in Nils's arms, we sped down the side of the cursed mountains,--anywhere, goal was of no account: we had but one impulse--to get away from that place. "So under the black trees and the far white stars that flashed through the still leaves overhead, we leaped down the mountain side, regardless of path or landmark, straight through the tangled underbrush, across mountain streams, through fens and copses, anywhere, so only that our course was downward. "How long we ran thus, I have no idea, but by and by the forest fell behind, and we found ourselves among the foothills, and fell exhausted on the dry short grass, panting like tired dogs.
