In June, 1812, war broke out between England and the United States. It was January before the people at Astoria heard of it. Finding themselves cut off from help on the one side, and threatened with capture on the other, Astor's agents sold the property to the North-west Company, into whose hands it thus passed, not without suspicion of collusion on the part of the sellers. This was in October, 1813. In this way an enterprise which had been sagaciously planned, backed with abundant means, and had passed through the preliminary stage of trial to assured success, came to an inglorious end because the Government lacked means to protect it. And so Americans were ousted from Oregon, and Englishmen put in possession, which was much like giving the wolf the wether to keep. LOUISIANA ADMITTED. Louisiana came into the Union in 1812, so making it the eighteenth State in the order of succession, as it was the first formed of any portion of the territory we had acquired west of the Mississippi. Louisiana is therefore the corner-stone of the new Great West. Louisiana came in at the beginning of a period of strife and bloodshed. England made a most desperate effort to seize New Orleans, with intent to obtain control of the Mississippi, or at least to gain a vantage-ground from which she could dictate terms to the United States. The fortune of war, however, went against her in the bloodiest battle of the time. Peace was already made when it was fought, so making the effort as useless as it was costly and heroic. III. THE OREGON TRAIL. THE TRAPPER, THE BACKWOODSMAN, AND THE EMIGRANT. Ever since the expedition of Lewis and Clarke, the head waters of the Missouri had been frequented by hunters, trappers, and traders. These men threaded every nook and corner of the wilderness in pursuit of a livelihood, and, rude geographers as they were, the remotest mountain solitudes were fast yielding up to them the secrets they had held since the creation of the world. Let us begin with a portrait of the trapper as drawn from life by Mr. Irving:— "When the trade in furs was chiefly pursued about the lakes and rivers, the expeditions were carried on in bateaux and canoes. The voyageurs or boatmen were the rank and file in the service of the trader, and even the hardy men of the North were fain to be paddled from point to point of their migrations.
