A significant gesture from her trembling cousin again drew her attention from the vessel to the boat. The animal, which now exhibited the delicate and glossy fur of the beaver, had gained the stern, and remained stationary within a foot of her quarter. Presently the sailor made a sluggish movement, turning himself heavily on his side, and with his face towards his curious and daring visitant. In the act the tarpaulin hat had fallen from his eyes, but still he awoke not. Scarcely had he settled himself in his new position, when, to the infinite horror of the excited cousins, a naked human hand was raised from beneath the surface of the lake, and placed upon the gunwale of the boat Then rose slowly, and still covered with its ingenious disguise, first the neck, then the shoulders, and finally the form, even to the midwaist, of a dark and swarthy Indian, who, stooping low and cautiously over the sailor, now reposed the hand that had quitted the gunwale upon his form, while the other was thrust searchingly into the belt encircling his waist. Miss de Haldimar would have called out, to apprise the unhappy man of his danger; but her voice refused its office, and her cousin was even less capable of exertion than herself. The deep throbbings of their hearts were now audible to each; for the dreadful interest they took in the scene, had excited their feelings to the most intense stretch of agony. At the very moment, however, when, with almost suspended animation, they expected to see the knife of the savage driven into the chest of the sleeping and unsuspecting sailor, the latter suddenly started up, and, instinct with the full sense of the danger by which he was menaced, in less time than we take to describe it, seized the tiller of his rudder, the only available instrument within his reach, and directing a powerful blow at the head of his amphibious enemy, laid him, without apparent life or motion, across the boat. "Almighty God! what can this mean?" exclaimed Miss de Haldimar, as soon as she could recover her presence of mind. "There is some fearful treachery in agitation; and a cloud now hangs over all, that will soon burst with irresistible fury on our devoted heads. Clara, my love," and she conducted the almost fainting girl to a seat, "wait here until I return. The moment is critical, and my father must be apprised of what we have seen. Unless the gates of the fort be instantly closed, we are lost." "Oh, Madeline, leave me not alone," entreated the sinking Clara. "We will go together. Perhaps I may be of service to you below." "The thought is good; but have you strength and courage to face the dark chiefs in the council-room. If so, hasten there, and put my father on his guard, while I fly across the parade, and warn Captain Baynton of the danger."
