A thought now flashed across the captain’s mind that they really had a plan to depose him, and that, having picked up some information at Owyhee, possibly of war between the United States and England, they meant to alter the destination of the voyage; perhaps to seize upon ship and cargo for their own use.

Once having conceived this suspicion, everything went to foster it.  They had distributed fire-arms among some of their men, a common precaution among the fur traders when mingling with the natives.  This, however, looked like preparation.  Then several of the partners and clerks and some of the men, being Scotsmen, were acquainted with the Gaelic, and held long conversations together in that language.  These conversations were considered by the captain of a “mysterious and unwarranted nature,” and related, no doubt, to some foul conspiracy that was brewing among them.  He frankly avows such suspicions, in his letter to Mr. Astor, but intimates that he stood ready to resist any treasonous outbreak; and seems to think that the evidence of preparation on his part had an effect in overawing the conspirators.

The fact is, as we have since been informed by one of the parties, it was a mischievous pleasure with some of the partners and clerks, who were young men, to play upon the suspicious temper and splenetic humors of the captain.  To this we may ascribe many of their whimsical pranks and absurd propositions, and, above all, their mysterious colloquies in Gaelic.

In this sore and irritable mood did the captain pursue his course, keeping a wary eye on every movement, and bristling up whenever the detested sound of the Gaelic language grated upon his ear.  Nothing occurred, however, materially to disturb the residue of the voyage excepting a violent storm; and on the twenty-second of March, the Tonquin arrived at the mouth of the Oregon, or Columbia River.

The aspect of the river and the adjacent coast was wild and dangerous.  The mouth of the Columbia is upwards of four miles wide with a peninsula and promontory on one side, and a long low spit of land on the other; between which a sand bar and chain of breakers almost block the entrance.  The interior of the country rises into successive ranges of mountains, which, at the time of the arrival of the Tonquin, were covered with snow.

A fresh wind from the northwest sent a rough tumbling sea upon the coast, which broke upon the bar in furious surges, and extended a sheet of foam almost across the mouth of the river.  Under these circumstances the captain did not think it prudent to approach within three leagues, until the bar should be sounded and the channel ascertained.  Mr. Fox, the chief mate, was ordered to this service in the whaleboat, accompanied by John Martin, an old seaman, who had formerly visited the river, and by three Canadians.  Fox requested to have regular sailors to man the boat, but the captain would not spare them from the service of the ship,
