For some time after hearing this mysterious noise, which had caused the rock to tremble around them, the two men remained motionless within their place of concealment.
At length Wilder cautiously and deliberately pushed aside the curtain. At first only a small portion of it—a corner, so as to make sure about the smoke.
It still oozed in, but not so voluminously as at first. It had evidently become attenuated, and was growing thinner. It appeared also to be ascending with rapidity, as up the funnel of a chimney having a good draught. For this reason it was carried past the mouth of the grotto without much of it drifting in, and they saw that they could soon safely withdraw the curtain. It was a welcome relaxation from the irksome task that had been so long imposed upon them, and the coat was at length permitted to drop down upon the ledge.
Although there were no longer any sounds heard, or other signs to indicate the presence of the Indians, the fugitives did not feel sure of their having gone; and it was some time before they made any attempt to reascend the shaft. Some of the pursuers might still be lurking near, or straying within sight. They had so far escaped death, as if by a miracle, and they were cautious of again tempting fate. They determined that for some time yet they would not venture out upon the ledge, but keep inside the grotto that had given them such well-timed shelter. Some sulky savage, disappointed at not getting their scalps, might take it into his head to return and hurl down into the hole another shower of stones. Such a whim was probable to a prairie Indian.
Cautious against all like contingencies, the guide counselled his younger companion to patience, and for a considerable time they remained without stirring out of their obscure chamber.
At length, however, perceiving that the tranquillity continued, they no longer deemed it rash to make a reconnoissance; and for this purpose Walt Wilder crawled out upon the ledge and looked upward. A feeling of surprise, mingled with apprehension, at once seized upon him.
“Kin it be night?” he asked, whispering the words back into the grotto.
“Not yet, I should think?” answered Hamersley. “The fight was begun before daybreak. The day can’t all have passed yet. But why do you ask, Walt?”
“Because thar’s no light comin’ from above. Whar’s the bit o’ blue sky we seed? Thar ain’t the breadth o’ a hand visible. It can’t a be the smoke as hides it. That seems most cleared off. Darned if I can see a steim o’ the sky. ’Bove as below, everything’s as black as the ten o’ spades. What kin it mean?”
Without waiting a reply, or staying for his companion to come out upon the ledge, Wilder rose to his feet, and, grasping the projecting points above his head, commenced swarming up the shaft, in a similar manner as that by which he had made the descent.
