He worked as untiringly as a steam engine, and aided by the swift current of the Columbia they made good progress toward the ocean.

All the way along the river the trapper was on the look-out for the returning canoe, in which Ravenna and Little Rifle had been taken to Astoria. Having seen nothing of it thus far, he had strong hopes of reaching the mouth of the Columbia so near behind it as to intercept their friends before they started for San Francisco.

At the same time there was the possibility, if not the probability, that the returning Blackfeet had either gone back overland or had avoided them.

The most vivid reminder that they were out of the woods was the sudden appearance of a sloop coming up-stream. It was under full sail, and at first sight of it Harry started and exclaimed that they were now indeed in a land of civilization.

The Columbia is ascended by large vessels to Fort Vancouver, about a hundred miles from the mouth, while vessels of very light draught now reach a point nearly double that distance.

A few miles further, and just as the day was drawing to a close, our friends came in sight of a schooner anchored close to shore.

Robsart ran the little boat alongside, and finding several of the crew aboard, made inquiries as to whether they had noticed a canoe going by at any time during the past few days.

Upon hearing the question the sailors laughed, and declared that they had seen fully a hundred during the week that they had been ascending the river; and even when the trapper explained particularly the number and general appearance of the occupants of the one he was seeking, the seamen could give no satisfactory answer, and Old Ruff resumed his journey, rather ill-naturedly remarking that it was no use of making inquiries of men who knew nothing and never would know any thing.

They had come a long distance during the day and the trapper needed rest. Accordingly the boat was run ashore, turned over on its face, and they sought and procured lodgings in a little settlement that stood back a short distance from the shore.

As may be believed, the sun was scarcely above the horizon when the canoe was again speeding down the Columbia, which was rapidly expanding in depth and width as they advanced.
