head land, presented a more even and less agitated surface.  This head land once doubled, the safety of the adventurers was ensured, since, although the tremendous current which swept through the inner channel must have borne them considerably downwards, still the canoe would have accomplished the transit below the town in perfect safety.  The fact of this opportunity being neglected, led at once to the inference that the adventurers were total strangers, and distinct voices were now raised by those on the bank, to warn them of their danger—­but whether it was that they heard not, or understood not, the warning was unnoticed.  Once indeed it seemed as if he who so ably conducted the course of the bark, had comprehended and would have followed the suggestion so earnestly given, for his tiny sail was seen to flutter for the first time in the wind, as with the intention to alter his course.  But an impatient gesture from his companion in the bow, who was seen to turn suddenly round, and utter something, (which was however inaudible to those onshore,) again brought the head of the fragile vessel to her original course, and onward she went leaping and bounding, apparently with the design to clear the whirlpool at a higher point of the river.  Nothing short of a miracle could now possibly enable them to escape being drawn into the boiling vortex, and, during the moments that succeeded, every heart beat high with fearful expectation as to the result.  At length the canoe came with a sudden plunge into the very centre of the current, which, all the skill of the steersman was insufficient to enable him to clear.  Her bow yawed, her little sail fluttered—­and away she flew, broadside foremost, down the stream with as little power of resistance as a feather or a straw.  Scarcely had the eye time to follow her in this peculiar descent, when she was in the very heart of the raging eddy.  For a moment she reeled like a top, then rolled two or three times over, and finally disappeared altogether.  Various expressions of horror broke from the several groups of whites and Indians, all of whom had anticipated the catastrophe without the power of actively interposing.  Beyond the advice that was given, not a word was uttered, but every eye continued fixed on the whirlpool, as though momentarily expecting to see something issue from its bosom.  After the lapse of a minute, a dark object suddenly presented itself some twenty yards below, between the island and the town.  It was the canoe which, bottom upwards, and deprived of its little mast and sail, had again risen to the surface, and was floating rapidly down with the current.  Presently afterwards two heads were seen nearly at the point where the canoe had again emerged.  They were the unfortunate adventurers, one of whom appeared to be supporting his companion with one arm, whilst with the other he dashed away the waters that bore them impetuously along.  The hats of both had fallen off, and as he who exerted himself so strenuously,
