He was to touch at the Sandwich Islands, inquire about the fortunes of the Tonquin, and whether an establishment had been formed at the mouth of the Columbia. If so, he was to take as many Sandwich Islanders as his ship could accommodate, and proceed thither. On arriving at the river, he was to observe great caution, for even if an establishment should have been formed, it might have fallen into hostile hands. He was, therefore, to put in as if by casualty or distress, to give himself out as a coasting trader, and to say nothing about his ship being owned by Mr. Astor, until he had ascertained that everything was right. In that case, he was to land such part of his cargo as was intended for the establishment, and to proceed to New Archangel with the supplies intended for the Russian post at that place, where he could receive peltries in payment. With these he was to return to Astoria; take in the furs collected there, and, having completed his cargo by trading along the coast, was to proceed to Canton. The captain received the same injunctions that had been given to Captain Thorn of the Tonquin, of great caution and circumspection in his intercourse with the natives, and that he should not permit more than one or two to be on board at a time.
The Beaver sailed from New York on the 10th of October, 1811, and reached the Sandwich Islands without any occurrence of moment.
Here a rumor was heard of the disastrous fate of the Tonquin.
Deep solicitude was felt by every one on board for the fate of both expeditions, by sea and land. Doubts were entertained whether any establishment had been formed at the mouth of the Columbia, or whether any of the company would be found there.
After much deliberation, the Captain took twelve Sandwich Islanders on board, for the service of the factory, should there be one in existence, and proceeded on his voyage.
On the 6th of May, he arrived off the mouth of the Columbia and running as near as possible, fired two signal guns. No answer was returned, nor was there any signal to be descried. Nigh coming on, the ship stood out to sea, and every heart drooped as the land faded away. On the following morning they again ran in within four miles of shore, and fired other signal guns, but still without reply. A boat was then despatched, to sound the channel, and attempt an entrance; but returned without success there being a tremendous swell, and breakers. Signal guns were fired again in the evening, but equally in vain, and once more the ship stood off to sea for the night. The captain now gave up all hope of finding any establishment at the place, and indulged in the most gloomy apprehensions. He feared his predecessor had been massacred before they had reached their place of destination; or if they should have erected a factory, that it had been surprised and destroyed by the natives.
In this moment of doubt and uncertainty, Mr. Clarke announced his determination, in case of the worst, to found an establishment with the present party, and all hands bravely engaged to stand by him in the undertaking. The next morning the ship stood in for the third time, and fired three signal guns, but with little hope of reply. To the great joy of the crew, three distinct guns were heard in answer. The apprehensions of all but Captain Sowle were now at rest. That cautious commander recollected the instructions given him by Mr. Astor, and determined to proceed with great circumspection. He was well aware of Indian treachery and cunning. It was not impossible, he observed, that these cannon might have been fired by the savages themselves. They might have surprised the fort, massacred its inmates; and these signal guns might only be decoys to lure him across the bar, that they might have a chance of cutting him off, and seizing his vessel.
At length a white flag was descried hoisted as a signal on Cape Disappointment. The passengers pointed to it in triumph, but the captain did not yet dismiss his doubts. A beacon fire blazed through the night on the same place, but the captain observed that all these signals might be treacherous.
On the following morning, May 9th, the vessel came to anchor off Cape Disappointment, outside of the bar. Towards noon an Indian canoe was seen making for the ship and all hands were ordered to be on the alert. A few moments afterwards, a barge was perceived following the canoe. The hopes and fears of those on board of the ship were in tumultuous agitation, as the boat drew nigh that was to let them know the fortunes of the enterprise, and the fate of their predecessors. The captain, who was haunted with the idea of possible treachery, did not suffer his curiosity to get the better of his caution, but ordered a party of his men under arms, to receive the visitors. The canoe came first alongside, in which were Comcomly and six Indians; in the barge were M'Dougal, M'Lellan, and eight Canadians. A little conversation with these gentlemen dispelled all the captain's fears, and the Beaver crossing the bar under their pilotage, anchored safely in Baker's Bay.
