When the time came to run the boundary line, the American and Mexican commissioners could not agree. So the United States paid ten million dollars more and received an additional strip of land between the Rio Grande and the Colorado rivers. This gave the United States its present southern boundary. This agreement was made in 1853 by James Gadsden for the United States, and the land bought is usually called the Gadsden Purchase.
但在谈及国界时，双方的外交官没有达成一致，为此，美国又付出1000多万美元，并获得里约·格兰德与科罗拉多河之间的一段狭长的土地，这使得美国拥有了其现在的南部边界。这个协议于1853年由詹姆斯·加兹登代表美国达成，因此这块买来的土地一般被称为"加兹登购买地"。
338. The Oregon Question.
338．俄勒冈问题
It was not only in the Southwest that boundaries were disputed; in the Northwest also there was a long controversy which was settled while Polk was President. Oregon was the name given to the whole region, between Spanish and Mexican California and the Russian Alaska. The United States and Great Britain each claimed to have the best right to Oregon. As they could not agree as to their claims, they decided to occupy the region jointly. As time went on American settlers and missionaries began to go over the mountains to Oregon. In 1847 seven thousand Americans were living in the Northwest.
不仅仅在西南部有边界争端，在西北部也有类似的问题长期存在，珀尔卡总统在任职期间解决了这些问题。西北部这个地区的总名称是俄勒冈，它处于西班牙、墨西哥的加利福尼亚和俄国的阿拉斯加之间，美国与大不列颠都宣称有最好的理由拥有对俄勒冈的主权，由于双方不能达成一致，两国决定共同占有这个地区。随着时间推移，美国殖民者和传教士开始越过山脉到达俄勒冈，1847年有7000美国人居住在西北部。
