A School History of the United States

%365. The "Wilmot Proviso."%—In 1846 the Mexican War was very hateful to many Northern people, and as a new House of Representatives was to be elected in the autumn of that year, Polk thought it wise to end the war if possible, and in August asked for $2,000,000 "for the settlement of the boundary question with Mexico." This, of course, meant the purchase of territory from her. But Mexico had abolished slavery in 1827, and lest any territory bought from her should be made slave soil, David Wilmot of Pennsylvania moved that the money should be granted, provided all territory bought with it should be free soil. The proviso passed the House, but not the Senate. Next year (1847) a bill to give Polk $3,000,000 with which to settle the boundary dispute was introduced, and again the proviso was attached. But the Senate rejected it, and the House then gave way, and passed the bill without the proviso.

%366. Conquest of New Mexico and California.%—While Taylor was winning victories in northeastern Mexico, Colonel Stephen W. Kearny was ordered to march into New Mexico. Leaving Fort Leavenworth in June, 1846, he went by the Upper Arkansas River to Bents Fort, thence southwest through what is now Colorado, and by the old Santa Fe trail to the Rio Grande valley and Santa Fe (p. 330). After taking the city without opposition, he declared the whole of New Mexico to be the property of the United States, and then started to seize California. On arriving there, he found the conquest completed by the combined forces of Stockton and Frémont.

%367. The Great American Desert.%—But how came Frémont to be in California in 1846?

If you look at any school geography published between 1820 and 1850 you will find that a large part of what is now Nebraska, Kansas, Colorado, Wyoming, Oklahoma, and Texas is put down as "THE GREAT AMERICAN DESERT." Many believed it was not unlike the Desert of Sahara, and that nobody would ever want to cross it, while there was so much fertile land to the eastward. This view made people very indifferent as to our claims to Oregon, so that when Thomas H. Benton, one of the senators from Missouri, and one of the far-sighted statesmen of the day, wanted Congress to seize and hold Oregon by force of arms, he was told that it was not worth the cost. "Oregon," said one senator, "will never be a state in the Union." "Build a railroad to Oregon?" said another. "Why, all the wealth of the Indies would not be sufficient for such a work."

%368. The Santa Fé and Oregon Trails.%—Some explorations you remember had been made. Lewis and Clark went across the Northwest to the mouth of the Columbia in 1804-1805, and Zebulon M. Pike had penetrated in 1806 to the wild mountainous region about the head waters of the Platte, Arkansas, and Rio Grande and had probably seen the great mountain that now bears his name. Major Long followed Pike in 1820, gave his name to Longs Peak, and brought back such a dismal account of the West that he was largely responsible for the belief in a desert. The great plains from the sources of the Sabine, Brazos, and Colorado rivers to the northern boundary Were, he said, "peculiarly adapted as a range for buffaloes, wild Goats, and other wild game," and "might serve as a barrier to prevent too great an expansion of our population westward;" but nobody would think of cultivating the plains. For years after that the American Fur Trading Company of St. Louis had annually sent forth its caravans into Oregon and New Mexico. Because the way was beset by hostile Indians, these caravans were protected by large and strongly armed bands, and in time wore out well-beaten tracks across the prairies and over the mountain passes, which came to be known on the frontier as the Santa Fé and Oregon Trails. In 1832 Captain Bonneville[1] took a wagon train over the Rocky Mountain divide into the Green River Valley, and Nathaniel J. Wyeth led a party from New England to the Oregon country, and in 1834 established Fort Hall in what is now Idaho. Still later in the thirties went Marcus Whitman and his party.

%369. %Explorations of Frémont.%—By this time it was clear that the tide of westward emigration would soon set in strongly towards Oregon. Then at last Benton succeeded in persuading Congress to order an exploration of the far West, and in 1842 Lieutenant Frémont was sent to see if the South Pass of the rocky Mountains, the usual crossing place, would best accommodate the coming emigration. He set out from Kansas City (then a frontier hamlet, now a prosperous city) with Kit Carson, a famous hunter, for guide, and following the wagon trails of those who had gone before him, made his way to the pass. He found its ascent so gradual that his party hardly knew when they reached the summit. Passing through it to the valley beyond, he climbed the great peak which now bears his name and stands 13,570 feet above the sea.

Though Frémont discovered no new route, he did much to dispel the popular idea created by Long that the plains were barren, and the American Desert began to shrink. In 1843 Frémont was sent out again. Making his way westward through the South Pass, where his work ended in 1842, he turned southward to visit Great Salt Lake, and then pushed on to Walla Walla on the Columbia River (see map on p. 330). Thence he went on to the Dalles, and then by boat to Fort Vancouver, and then, after returning to the Dalles, southward to Sutter's Fort in the Sacramento valley, and so back to the States in 1844.

In 1845 Frémont, who had now won the name of "Pathfinder," was sent out a third time, and crossing what are now Nebraska and Utah, reached the vicinity of Monterey in California. The Mexican authorities ordered him out of the country. But he spent the winter in the mountains, and in the spring was on his way to Oregon, when a messenger from Washington overtook him, and he returned to Sutter's Fort.
