An event happened the following year which made the Washington Government doubt the wisdom of basing its claims upon the Louisiana cession. It was the Treaty with Spain ceding the Floridas. As we have seen in one of the earlier chapters of this work, this Treaty contained a provision ceding to the United States all the rights and sovereignty of Spain in and over the territory lying west of the Rocky Mountains and north of the forty-second parallel of north latitude. Here was a much better claim, both as to quantity of territory and quality of right, than could be founded on the Louisiana cession. If the United States had possessed this claim in 1803, it is doubtful if we should ever have heard of the notion that Oregon was a part of Louisiana. {314} [Sidenote: Continuation of the convention of 1818.] In 1828, the agreement of 1818 was indefinitely continued, but might be terminated by a twelvemonth's notice by either party, at any time. The United States, was, however, in a better position than before, on account of having now the Spanish claims to all territory above the forty-second parallel on the Pacific. The element of greatest importance in the settlement of the question was, of course, colonization within the territory, and neither party had really undertaken that. The hunters and trappers and agents of the Hudson's Bay Company had temporary abodes within the territory, especially north of the Columbia, and there was one settlement on the south bank under the protection of the United States, and that was all. [Sidenote: The British policy in reference to Oregon.] For some fourteen years longer, now, this indefinite status continued. In the negotiations between Mr. Webster and Lord Ashburton, in 1841 and 1842, Mr. Webster sounded Lord Ashburton on the Oregon question, and found that the Queen's agent had received no power to deal with the matter, but drew the conclusion that the British policy in regard to Oregon was to prolong the existing _modus vivendi_, give the Hudson's Bay Company time to settle the country north of the Columbia, and then agree to a division on the line of that river.
