It is impossible to convey an idea of the extraordinary vehemence, the wild accents, the frantic looks, with which Nathan ended the horrid story, into which he had been betrayed by his repining companion. His struggles to subdue the passions that the dreadful recollections of a whole family's butchery awoke in his bosom, only served to add double distortion to his changes of countenance, which, a better index of the convulsion within than were his broken, incoherent, half-inarticulate words, assumed at last an appearance so wild, so hideous, so truly terrific, that Roland was seized with horror, deeming himself confronted with a raging maniac. He raised his hand to remove that of Nathan, which still clutched his arm, and clutched it with painful force; but while in the act, the fingers relaxed of themselves, and Nathan dropped suddenly to the earth, as if struck down by a thunderbolt, his mouth foaming, his eyes distorted, his hands clenched, his body convulsed,--in short, exhibiting every proof of an epileptic fit, brought on by overpowering agitation of mind. As he fell, little Peter sprang to his side, and throwing his paws on his unconscious master's breast, stood over him as if to protect him, growling at Roland; who, though greatly shocked at the catastrophe, did not hesitate to offer such relief as was in his power.

The soldier had heard that injuries to the head often resulted in insanity of some species or other; he could now speculate, on better grounds, and with better reason, upon some of those singular points of character which seemed to distinguish the houseless Nathan from the rest of his fellow-men. CHAPTER XXIV. The convulsion was but momentary, and departed with almost the same suddenness that marked its accession. Nathan started half up, looked wildly around him, surveying the bodies of the two Piankeshaws, and the visage of the sympathising soldier. Then snatching up and replacing his hat with one hand, and grasping Roland's with the other, he exclaimed, as if wholly unconscious of what had happened him,--
