"What is it?" murmured Alice, after a few moments of terrible suspense.

"What is it?" repeated Hewyard aloud.

Neither Hawkeye nor the Indians made any reply. They listened, as if expecting the sound would be repeated, with a manner that expressed their own astonishment. At length they spoke together, earnestly, in the Delaware language, when Uncas, passing by the inner and most concealed aperture, cautiously left the cavern. When he had gone, the scout first spoke in English.

"What it is, or what it is not, none here can tell, though two of us have ranged the woods for more than thirty years. I did believe there was no cry that Indian or beast could make, that my ears had not heard; but this has proved that I was only a vain and conceited mortal."

"Was it not, then, the shout the warriors make when they wish to intimidate their enemies?" asked Cora who stood drawing her veil about her person, with a calmness to which her agitated sister was a stranger.

"No, no; this was bad, and shocking, and had a sort of unhuman sound; but when you once hear the war-whoop, you will never mistake it for anything else. Well, Uncas!" speaking in Delaware to the young chief as he re-entered, "what see you? do our lights shine through the blankets?"

The answer was short, and apparently decided, being given in the same tongue.

"There is nothing to be seen without," continued Hawkeye, shaking his head in discontent; "and our hiding-place is still in darkness. Pass into the other cave, you that need it, and seek for sleep; we must be afoot long before the sun, and make the most of our time to get to Edward, while the Mingoes are taking their morning nap."

Cora set the example of compliance, with a steadiness that taught the more timid Alice the necessity of obedience. Before leaving the place, however, she whispered a request to Duncan, that he would follow. Uncas raised the blanket for their passage, and as the sisters turned to thank him for this act of attention, they saw the scout seated again before the dying embers, with his face resting on his hands, in a manner which showed how deeply he brooded on the unaccountable interruption which had broken up their evening devotions.

Heyward took with him a blazing knot, which threw a dim light through the narrow vista of their new apartment. Placing it in a favorable position, he joined the females, who now found themselves alone with him for the first time since they had left the friendly ramparts of Fort Edward.

"Leave us not, Duncan," said Alice: "we cannot sleep in such a place as this, with that horrid cry still ringing in our ears."

"First let us examine into the security of your fortress," he answered, "and then we will speak of rest."

He approached the further end of the cavern, to an outlet, which, like the others, was concealed by blankets; and removing the thick screen, breathed the fresh and reviving air from the cataract. One arm of the river flowed through a deep, narrow ravine, which its current had worn in the soft rock, directly beneath his feet, forming an effectual defense, as he believed, against any danger from that quarter; the water, a few rods above them, plunging, glancing, and sweeping along in its most violent and broken manner.

"Nature has made an impenetrable barrier on this side," he continued, pointing down the perpendicular declivity into the dark current before he dropped the blanket; "and as you know that good men and true are on guard in front I see no reason why the advice of our honest host should be disregarded. I am certain Cora will join me in saying that sleep is necessary to you both."

"Cora may submit to the justice of your opinion though she cannot put it in practice," returned the elder sister, who had placed herself by the side of Alice, on a couch of sassafras; "there would be other causes to chase away sleep, though we had been spared the shock of this mysterious noise. Ask yourself, Heyward, can daughters forget the anxiety a father must endure, whose children lodge he knows not where or how, in such a wilderness, and in the midst of so many perils?"

"He is a soldier, and knows how to estimate the chances of the woods."

"He is a father, and cannot deny his nature."

"How kind has he ever been to all my follies, how tender and indulgent to all my wishes!" sobbed Alice. "We have been selfish, sister, in urging our visit at such hazard."

"I may have been rash in pressing his consent in a moment of much embarrassment, but I would have proved to him, that however others might neglect him in his strait his children at least were faithful."

"When he heard of your arrival at Edward," said Heyward, kindly, "there was a powerful struggle in his bosom between fear and love; though the latter, heightened, if possible, by so long a separation, quickly prevailed. 'It is the spirit of my noble-minded Cora that leads them, Duncan', he said, 'and I will not balk it. Would to God, that he who holds the honor of our royal master in his guardianship, would show but half her firmness!'"

"And did he not speak of me, Heyward?" demanded Alice, with jealous affection; "surely, he forgot not altogether his little Elsie?"

"That were impossible," returned the young man; "he called you by a thousand endearing epithets, that I may not presume to use, but to the justice of which, I can warmly testify. Once, indeed, he said - "

Duncan ceased speaking; for while his eyes were riveted on those of Alice, who had turned toward him with the eagerness of filial affection, to catch his words, the same strong, horrid cry, as before, filled the air, and rendered him mute. A long, breathless silence succeeded, during which each looked at the others in fearful expectation of hearing the sound repeated. At length, the blanket was slowly raised, and the scout stood in the aperture with a countenance whose firmness evidently began to give way before a mystery that seemed to threaten some danger, against which all his cunning and experience might prove of no avail.
