In an instant his frenzy was at an end.  He gazed for a time in mute bewilderment upon his victim; then drawing his buffalo robe over his head, he sat down beside the corpse, and remained brooding over his crime and his loss.  Three days elapsed, yet the chief continued silent and motionless; tasting no food, and apparently sleepless.  It was apprehended that he intended to starve himself to death; his people approached him in trembling awe, and entreated him once more to uncover his face and be comforted; but he remained unmoved.  At length one of his warriors brought in a small child, and laying it on the ground, placed the foot of the Blackbird upon its neck.  The heart of the gloomy savage was touched by this appeal; he threw aside his robe; made an harangue upon what he had done; and from that time forward seemed to have thrown the load of grief and remorse from his mind.

He still retained his fatal and mysterious secret, and with it his terrific power; but, though able to deal death to his enemies, he could not avert it from himself or his friends.  In 1802 the small-pox, that dreadful pestilence, which swept over the land like a fire over the prairie, made its appearance in the village of the Omahas.  The poor savages saw with dismay the ravages of a malady, loathsome and agonizing in its details, and which set the skill and experience of their conjurors and medicine men at defiance.  In a little while, two thirds of the population were swept from the face of the earth, and the doom of the rest seemed sealed.  The stoicism of the warriors was at an end; they became wild and desperate; some set fire to the village as a last means of checking the pestilence; others, in a frenzy of despair, put their wives and children to death, that they might be spared the agonies of an inevitable disease, and that they might all go to some better country.

When the general horror and dismay was at its height, the Blackbird himself was struck down with the malady.  The poor savages, when they saw their chief in danger, forgot their own miseries, and surrounded his dying bed.  His dominant spirit, and his love for the white men, were evinced in his latest breath, with which he designated his place of sepulture.  It was to be on a hill or promontory, upwards of four hundred feet in height, overlooking a great extent of the Missouri, from whence he had been accustomed to watch for the barks of the white men.  The Missouri washes the base of the promontory, and after winding and doubling in many links and mazes in the plain below, returns to within nine hundred yards of its starting-place; so that for thirty miles navigating with sail and oar the voyager finds himself continually near to this singular promontory as if spell-bound.

It was the dying command of the Blackbird that his tomb should be on the summit of this hill, in which he should be interred, seated on his favorite horse, that he might overlook his ancient domain, and behold the barks of the white men as they came up the river to trade with his people.
