Among the traders far up in the interior, in command of Fort Kamloops, which was at the junction of the North and South Thompson, was a Scotchman named Samuel Black. There came as a visitor to his fort a man of science and a countryman of his own. This man was David Douglas. He was an enthusiast in the search for plants and birds. He was indefatigable as a naturalist, did much service to the botany of Western America, and has his name preserved in the characteristic tree of the Pacific slope—the Douglas Fir. Douglas, on visiting Black, was very firm in the expression of his opinions against the Company, saying, "The Hudson's Bay Company is simply a mercenary corporation; there is not an officer in it with a soul above a beaver's skin." Black's Caledonian blood was roused, for he was a leading spirit among the traders, having on the union of the Companies been presented with a ring with the inscription on it, "To the most worthy of the worthy Nor'-Westers." He challenged the botanist to a duel. The scientist deferred the meeting till the morning, but early next day Black tapped at the parchment window of the room where Douglas was sleeping, crying, "Mister Douglas, are ye ready?" Douglas disregarded the invitation. David Douglas some time after visited Hawaii, where, in examining the snares for catching wild cattle, he fell into the pit, and was trampled to death by a wild bullock.

The death of Samuel Black was tragic. In 1841, Tranquille, a chief of the Shushwaps, who dwelt near Kamloops, died. The friends of the chief blamed the magic or "evil medicine" of the white man for his death. A nephew of Tranquille waited his opportunity and shot Chief Trader Black. The Hudson's Bay Company was aroused to most vigorous action. A writer says: "The murderer escaped. The news spread rapidly to the neighbouring posts. The natives were scarcely less disturbed than the white men. The act was abhorred, even by the friends and relatives of Tranquille. Anderson was at Nisqually at the time. Old John Tod came over from Fort Alexandria, McLean from Fort Colville, and McKinley and Ermatinger from Fort Okanagan. From Fort Vancouver McLoughlin sent men.... Cameron was to assist Tod in taking charge of Kamloops. All traffic was stopped.

"Tod informed the assembled Shushwaps that the murderer must be delivered up. The address of Nicola, chief of the Okanagans, gives a fine example of Indian eloquence. He said: 'The winter is cold. On all the hills around the deer are plenty; and yet I hear your children crying for food. Why is this? You ask for powder and ball, they refuse you with a scowl. Why do the white men let your children starve? Look there! Beneath yon mound of earth lies him who was your friend, your father. The powder and ball he gave you that you might get food for your famishing wives and children, you turned against him. Great heavens! And are the Shushwaps such cowards, dastardly to shoot their benefactor in the back while his face was turned? Yes, alas, you have killed your father! A mountain has fallen! The earth is shaken! The sun is darkened! My heart is sad. I cannot look at myself in the glass. I cannot look at you, my neighbours and friends. He is dead, and we poor Indians shall never see his like again. He was just and generous. His heart was larger than yonder mountain, and clearer than the waters of the lake. Warriors do not weep, but sore is my breast, and our wives shall wail for him. Wherefore did you kill him? But you did not. You loved him. And now you must not rest until you have brought to justice his murderer.'

"The old man was so rigid in expression that his whole frame and features seemed turned to stone.

"Archibald McKinley said, 'Never shall I forget it; it was the grandest speech I ever heard.'

"The murderer was soon secured and placed in irons, but in crossing a river he succeeded in upsetting the boat in the sight of Nicola and his assembled Indians. The murderer floated down the stream, but died, his death song hushed by the crack of rifles from the shore."

Thus by courage and prudence, alas! not without the sacrifice of valuable lives, was the power of the Hudson's Bay Company and the prestige of Great Britain established on the Pacific Coast.
