He assembled several of the chieftains whom he believed to be in the conspiracy.

When they were all seated around, he informed them that he had heard of the treachery of some of their northern brethren towards the Tonquin, and was determined on vengeance.

"The white men among you," said he, "are few in number, it is true, but they are mighty in medicine.

See here," continued he, drawing forth a small bottle and holding it before their eyes, "in this bottle I hold the small-pox, safely corked up; I have but to draw the cork, and let loose the pestilence, to sweep man, woman, and child from the face of the earth." The chiefs were struck with horror and alarm.

They implored him not to uncork the bottle, since they and all their people were firm friends of the white men, and would always remain so; but, should the small-pox be once let out, it would run like wildfire throughout the country, sweeping off the good as well as the bad; and surely he would not be so unjust as to punish his friends for crimes committed by his enemies.
Mr.M'Dougal pretended to be convinced by their reasoning, and assured them that, so long as the white people should be unmolested, and the conduct of their Indian neighbors friendly and hospitable, the phial of wrath should remain sealed up; but, on the least hostility, the fatal cork should be drawn.
From this time, it is added, he was much dreaded by the natives, as one who held their fate in his hands, and was called, by way of preeminence, "the Great Small-pox Chief." All this while, the labors at the infant settlement went on with unremitting assiduity, and, by the 26th of September, a commodious mansion, spacious enough to accommodate all hands, was completed.
