"Right, then, through the dog's brain,--fire!" The crash of the pieces, and the fall of the two victims, both marked by a fatal aim, and both pierced through the brain, were the first announcement of peril to their companions; who, springing up, with yells of fear and astonishment, and snatching at their arms, looked wildly around them for the unseen foe. The prisoner, also, astounded out of his despair, raised his head from the grass, and glared around. The wreaths of smoke curling over the bushes on the hill-side, betrayed the lurking place of the assailants; and savages and prisoner turning together, they all beheld at once the spectacle of two human heads,--or, to speak more correctly, two human caps, for the heads were far below them,--rising in the smoke, and peering over the bushes, as if to mark the result of the volley. Loud, furious, and exulting were the screams of the Indians, as with the speed of thought, seduced by a stratagem often practised among the wild heroes of the border, they raised and discharged their pieces against the imaginary foes so incautiously exposed to their vengeance. The caps fell, and with them the rifles that had been employed to raise them; and the voice of Nathan thundered through the glen, as he grasped his tomahawk and sprang from the ditch,--"Now, friend! up with thee axe, and do thee duty!" With these words, the two assailants at once leaped into view, and with a bold hurrah, and bolder hearts, rushed towards the fire, where lay the undischarged rifles of their first victims. The savages yelled also in reply, and two of them bounded forward to dispute the prize. The third, staggered into momentary inaction by the suddenness and amazement of the attack, rushed forward but a step; but a whoop of exultation was on his lips, as he raised the rifle which _he_ had not yet discharged, full against the breast of Tiger Nathan. But, his triumph was short-lived; the blow, so fatal as it must have proved to the life of Nathan, was averted by an unexpected incident. The prisoner, near whom he stood, putting all his vigour into one tremendous effort, burst his bonds, and, with a yell ten times louder and fiercer than had yet been uttered, added himself to the combatants. With a furious cry of encouragement to his rescuers,--"Hurrah for Kentucky!--give it to 'em good!" he threw himself upon the savage, beat the gun from his hands, and grasping him in his brawny arms, hurled him to the earth, where, rolling over and over in mortal struggle, growling and whooping, and rending one another like wild beasts, the two, still locked in furious embrace, suddenly tumbled down the banks of the brook, there high and steep, and were immediately lost to sight.
