"Still, I noted with some uneasiness, my companions hesitated, their minds, I suppose, a prey to feelings for which they could not have found a rational explanation. All this, however, really was not strange, for it was truly a wild and savage and awesome place and hour. "At length, in an evil moment, we moved forward. "Yes, soon there could be no doubt whatever about it: the trail led straight toward those rocks. What would we find there? "So engrossed were we that we did not see it coming. There was a sudden exclamation, we halted, and there was the fog--the dreaded fog that we had forgotten--drifting about us. The next moment it was gone, but more was drifting after. We resumed our advance. It was not far now. Why couldn't the fog have waited a little longer? But what did it matter? It could affect but little our immediate purpose; and, though I knew that it would be difficult, surely we could find our way back to the camp. "The fog thinned, and the rocks loomed up before us, dim and ghostly but close at hand. Then the vapor thickened about us again, and they were gone. We were in the midst of crevasses now and had to proceed with great caution. How it happened none of us knew; but of a sudden we saw that we had lost the trail. But we did not turn back to find it. It didn't matter, really. The demon and the angel had gone to those rocks. Of that we were certain. And there the rocks were, right there before us. 'Tis true we couldn't see them now, but they were there. "We went on. Minutes passed. And still there were no rocks. At length we had to acknowledge it: in the twistings and turnings we had been compelled to make among those cursed crevasses, we had missed our objective, and now we knew not where we were. "But we knew that we were not far. White and Long cursed and wanted to know how we were ever going to find our way back through this fog, since we had failed to find the rocks when they had been right there in front of us. But it was nothing really serious; we would find that rock-mass. We started. Of a sudden Long gave a sharp but low exclamation, and his hand clutched at my arm. "'What is it?' I asked in a voice low and guarded. "'_Voices!_' he whispered." Chapter 5 "DROME!" "We listened. Not a sound. Suddenly the glacier cracked and boomed, then silence again. We waited, listening. Still not the faintest sound. Long, so White and I decided, must have been deceived. But Long declared that he had not. "'I heard voices, I tell you! I know that I was not mistaken at all. I heard voices.' "Again we listened. "'There!' Long said suddenly. 'Hear them?'
