The ship in which the party was to sail was the Tonquin, commanded by a Captain Thorn, a somewhat stern officer, with whom the fur traders had many conflicts on their outbound journey. The report having gone abroad that a British cruiser from Halifax would come down upon the Tonquin and arrest the Canadians on board her, led to the application being made to the United States frigate Constitution to give the vessel protection. On September 10th, 1810, the Tonquin with her convoy put out and sailed for the Southern Main.

Notwithstanding the constant irritation between the captain and his fur trading passengers, the vessel went bravely on her way. After doubling Cape Horn on Christmas Day, they reached the Sandwich Islands in February, and after paying visits of ceremony to the king, obtained the necessary supplies of hogs, fruits, vegetables, and water from the inhabitants, and also engaged some twenty-four of the islanders, or Kanakas, as they are called, to go as employés to the Columbia.

Like a number of rollicking lads, the Nor'-Westers made very free with the natives, to the disgust of Captain Thorn. He writes:—"They sometimes dress in red coats and otherwise very fantastically, and collecting a number of ignorant natives around them, tell them they are the great chiefs of the North-West ... then dressing in Highland plaids and kilts, and making bargains with the natives, with presents of rum, wine, or anything that is at hand."

On February 28th the Tonquin set sail from the Sandwich Islands. The discontent broke out again, and the fur traders engaged in a mock mutiny, which greatly alarmed the suspicious captain. They spoke to each other in Gaelic, had long conversations, and the captain kept an ever-watchful eye upon them; but on March 22nd they arrived at the mouth of the Columbia River.

McKay and McDougall, as senior partners, disembarked, visited the village of the Chinooks, and were warmly welcomed by Comcomly, the chief of that tribe. The chief treated them hospitably and encouraged their settling in his neighbourhood. Soon they had chosen a site for their fort, and with busy hands they cut down trees, cleared away thickets, and erected a residence, stone-house, and powder magazine, which was not, however, at first surrounded with palisades. In honour of the promoter of their enterprise, they very naturally called the new settlement Astoria.

As soon as the new fort had assumed something like order, the Tonquin, according to the original design, was despatched up the coast to trade with the Indians for furs. Alexander McKay took charge of the trade, and sought to make the most of the honest but crusty captain. The vessel sailed on July 5th, 1811, on what proved to be a disastrous journey.

As soon as she was gone reports began to reach the traders at Astoria that a body of white men were building a fort far up the Columbia. This was serious news, for if true it meant that the supply of furs looked for at Astoria would be cut off. An effort was made to find out the truth of the rumour, without success, but immediately after came definite information that the North-West Company agents were erecting a post at Spokane. We have already seen that this was none other than David Thompson, the emissary of the North-West Company, sent to forestall the building of Astor's fort.

Though too late to fulfil his mission, on July 15th the doughty astronomer and surveyor, in his canoe manned by eight men and having the British ensign flying, stopped in front of the new fort. Thompson was cordially received by McDougall, to the no small disgust of the other employés of the Astor Company. After waiting for eight days, Thompson, having received supplies and goods from McDougall, started on his return journey. With him journeyed up the river David Stuart, who, with eight men, was proceeding on a fur-trading expedition. Among his clerks was Alexander Ross, who has left a veracious history of the "First Settlers on the Oregon." Stuart had little confidence in Thompson, and by a device succeeded in getting him to proceed on his journey and leave him to choose his own site for a fort. Going up to within 140 miles of the Spokane River, and at the junction of the Okanagan and Columbia, Stuart erected a temporary fort to carry on his first season's trade.

In the meantime the Tonquin had gone on her way up the coast. The Indians were numerous, but were difficult to deal with, being impudent and greedy. A number of them had come upon the deck of the Tonquin, and Captain Thorn, being wearied with their slowness in bargaining and fulness of wiles, had grown impatient with the chief and had violently thrown him over the side of the ship. The Indians no doubt intended to avenge this insult. Next morning early, a multitude of canoes came about the Tonquin and many savages clambered upon the deck. Suddenly an attack was made upon the fur traders. Alexander McKay was one of the first to fall, being knocked down by a war club. Captain Thorn fought desperately, killing the young chief of the band, and many others, until at last he was overcome by numbers. The remnant of the crew succeeded in getting control of the ship and, by discharging some of the deck guns, drove off the savages. Next morning the ship was all quiet as the Indians came about her. The ship's clerk, Mr. Lewis, who had been severely wounded, appeared on deck and invited them on board. Soon the whole deck was crowded by the Indians, who thought they would secure a prize. Suddenly a dreadful explosion took place. The gunpowder magazine had blown up, and Lewis and upward of one hundred savages were hurled into eternity. It was a fierce revenge! Four white men of the crew who had escaped in a boat were captured and terribly tortured by the maddened Indian survivors. An Indian interpreter alone was spared to return to Astoria to relate the tale of treachery and blood.

Astor's plan involved, however, the sending of another expedition overland to explore the country and lay out his projected chain of forts. In charge of this party was William P. Hunt, of Trenton, New Jersey, who had been selected by Astor, as being a native-born American, to be next to himself in authority in the Company. Hunt had no experience as a fur trader, but was a man of decision and perseverance. With him was closely associated Donald McKenzie, who had been in the service of the North-West Company, but had been induced to join in the partnership with Astor.
