339. The Oregon Treaty, 1846.
339．俄勒冈条约（1846年）
The matter was now taken up in earnest. "All Oregon or none," "Fifty-four forty or fight," became popular cries. The United States gave notice of the ending of the joint occupation. The British government suggested that Oregon should be divided between the two nations. In 1818 he boundary between the United States and British North America had been fixed as the forty-ninth parallel from the Lake of the Woods to the Rocky Mountains. It was now proposed to continue this line to the Pacific. The British government, however, insisted that the western end of the line should follow the channel between Vancouver's Island and the mainland so as to make that island entirely British. The Mexican War was now coming on. It would hardly do to have two wars at one time. So the United States gave way and a treaty was signed in 1846. Instead of "all Oregon," the United States received about one-half. But it was a splendid region and included not merely the present state of Oregon, but all the territory west of the Rocky Mountains between the forty-second and the forty-ninth parallels of latitude.
此时到了认真解决这个问题的时候，"全占或放弃，只有一个俄勒冈"、"54度到40度，否则就开战"成为当时流行的口号。美国政府发出结束共同占有俄勒冈的声音，英国政府则建议将俄勒冈分割给两个国家。1818年美国与美洲北部英国领地的界限被确定为从伍兹湖到落基山脉与49度纬线平行的一条线，现在美国提出将这条线延长到太平洋。然而，英国政府坚持这条线的西端应该按照温哥华岛屿与大陆之间的海峡来划定，这样可以使得这个岛屿完全属于英国。此时墨西哥战争已经打响，美国不可能同时与两个国家开战，因此，美国做出让步，英美于1846年签订条约。美国没有得到"整个俄勒冈"，而是得到这个地区的一半，但这个地区极其美好，它不仅包括今天的俄勒冈州，还包括落基山脉以西位于42度纬线与49度纬线之间的地区。
