When they were within four days' ride of Bent's Fort they met a caravan traveling toward Taos. The leader told Whitman that a party of mountaineers was about leaving Bent's Fort for St. Louis, but added that Whitman and Lovejoy, hampered by their pack animals, would not be in time to join them.

Whitman was very anxious to join the mountaineers if he could, and decided to leave Lovejoy and the guide with the pack-mules. Taking the fastest horse, and a small store of food, he rode on alone, hoping to catch the party. To do this he would have to travel on Sunday, something they had not done before.

Lovejoy saw Dr. Whitman start on his ride, but when the former reached Bent's Fort four days later he was astonished to find that Whitman had not arrived there, nor been heard from. As that part of the country was full of packs of gray wolves, now half-starved on account of the snow, Lovejoy was alarmed.

If not a prey to the wolves, Whitman must be lost; so his friend took a good guide from the Fort and started to search for him. He traveled up-river a hundred miles, and there fell in with Indians who told him of a lost white man who was trying to find the Fort, and whom they had directed down the river. Lovejoy went back, and late that afternoon saw Whitman come riding in, convinced that his journey had been so much delayed because he had traveled on Sunday.

The party of mountaineers had already left, but a messenger had been sent after them, and they stayed in camp, waiting for Whitman. Tired as he was, he started out immediately with a new guide, particularly eager to join this company, because they were now nearing the outposts of civilization, where the worst white men and Indians beset the pioneers. Lovejoy waited at Bent's Fort, and went east with the next caravan that started for St. Louis.

Whitman came safely through to St. Louis, where he had friends. He was at once surrounded by trappers and traders in Indian goods and furs who wanted news of the plains. In his turn he asked news of Congress, and learned that the Ashburton Treaty, settling a part of the boundary between Canada and the United States, had been approved and signed, but that the question of Oregon had not been settled, and from the reports of what had been said in the debates at Washington he knew that none of the American statesmen realized what a great prize Oregon Territory was.

He must reach the capital before Congress adjourned if possible. The rivers were frozen, and he had to rely on a journey by stage, slow at all times, but especially so in midwinter. He toiled slowly eastward, taking one coach after another, swinging and swaying and rocking across the center of the country, and reaching the capital in time to plead the cause of the northwest.

Washington was used to many strange types of men in those pioneer days, but even among such Marcus Whitman was a striking figure. He was of medium height, compact of build, with big shoulders and a large head. His hair was iron gray, and that, as well as his moustache and beard, had not been cut for four months. He was of pioneer type, living so long among Indians and trappers, and watching so constantly for wolves and bears, that he seemed awkward and uncouth in an eastern city. His clothes were a coarse fur jacket with buckskin breeches, fur leggings, and boot moccasins. Over these he wore a buffalo overcoat, with a head-hood for bad weather. He did not show an inch of woven garment.

Whitman reached Washington in March, 1843, and immediately urged his case before President Tyler, Secretary of State Daniel Webster, and many congressmen. He found the densest ignorance concerning Oregon Territory, a tract of territory which has since been divided into the three states of Washington, Oregon, and Idaho. A senator had said of that territory, "What is the character of this country? As I understand it there are seven hundred miles this side of the Rocky Mountains that are uninhabitable; where rain never falls; mountains wholly impassable, except through gaps and depressions, to be reached only by going hundreds of miles out of the direct course.... Of what use would it be for agricultural purposes? I would not, for that purpose, give a pinch of snuff for the whole territory. I wish the Rocky Mountains were an impassable barrier. If there was an embankment of even five feet to be removed I would not consent to expend five dollars to remove it and enable our population to go there." Another statesman declared, "With the exception of land along the Willamette and strips along other water courses, the whole country is as irreclaimable and barren a waste as the Desert of Sahara. Nor is this the worst; the climate is so unfriendly to human life that the native population has dwindled away under the ravages of malaria." And newspaper opinions were no more favorable. The Louisville Journal wrote, "Of all the countries upon the face of the earth Oregon is one of the least favored by heaven. It is the mere riddlings of creation. It is almost as barren as Sahara and quite as unhealthy as the Campagna of Italy. Russia has her Siberia and England has her Botany Bay, and if the United States should ever need a country to which to banish her rogues and scoundrels, the utility of such a region as Oregon would be demonstrated. Until then, we are perfectly willing to leave this magnificent country to the Indians, trappers and buffalo hunters that roam over its sand-banks."

Marcus Whitman had ridden four thousand miles, and starved, frozen, and never rested in order to overcome such opinions. The President and Daniel Webster were polite to him, but neither seemed to think much of the northwest. As he was describing the richness of the country, its fertile soil, great forests, precious minerals, and delightful climate, Webster interrupted. "But Oregon is shut off by impassable mountains and a great desert, which make a wagon road impossible," said he. Whitman answered, "Six years ago I was told there was no wagon road to Oregon, and it was impossible to take a wagon there, and yet in despite of pleadings and almost threats, I took a wagon over the road and have it now." The missionary's earnest, forceful manner impressed both President Tyler and Secretary Webster, and gradually they began to think it might be worth while to protect the claim of the United States to that country. Finally Whitman said, "All I ask is that you won't barter away Oregon, or allow English interference until I can lead a band of stalwart American settlers across the plains: for this I will try to do."
