As a result the far West became the Mecca of the fur trappers and traders. Commencing with the Astoria settlement in 1807, for the next forty years or until the opening of the Oregon immigration in 1844, they were practically the only whites to visit it outside of the missionaries, who did more or less exploring and visiting the Indians resulting in the Rev. Jason Lee in 1833 and Dr. Marcus Whitman in 1835 having established mission stations in Oregon. The next record is of one Robert Mills of Virginia who suggested in a publication on "Internal Improvements in Maryland, Virginia, and South Carolina," issued in 1819, the advisability of connecting the head of navigation of some one of the principal streams entering the Atlantic with the Pacific Ocean by a system of steam propelled carriages. (H. R. Doc. 173, 29th Cong.) This was before there was a mile of Steam Railroad in the world, and under the then existing circumstances was so chimerical as to hardly warrant mention. In a weekly newspaper published in 1832 at Ann Arbor, Michigan, called "The Emigrant," appeared what was probably the first suggestion in print on the advisability of a Pacific Railroad. The article suggests the advisability of building a line from New York to the Mouth of the Oregon (Columbia River) by way of the south shore of Lake Erie and Lake Michigan, crossing the Mississippi River between 41 and 42 north latitude, the Missouri River about the mouth of the Platte, thence to the Rocky Mountains near the source of the last named river, crossing them and down the valley of the Oregon to the Pacific. It further suggested that it be made a national project, or this failing the grant of three millions of acres to a Company organized for the purpose of constructing it. No name was signed to the article, but the probabilities are that it was written by S. W. Dexter, the Editor of the paper. With the Whitman party leaving the East for the far northwest to establish a Mission Station was the Rev. Samuel Parker, a Presbyterian minister, who was sent under the auspices of the Missionary Board of his Church to investigate and report on the mission situation and to suggest a plan for Christianizing the Indians. He crossed the continent to Oregon and on his return in 1838, his journal was published. It presented a very correct and interesting account of the scenes he visited. In it he says, "There would be no difficulty in the way of constructing a railroad from the Atlantic to the Pacific Ocean * * * * and the time may not be so far distant when trips will be made across the continent as they are now to Niagara Falls to see Nature's wonders." To just whom belongs the credit of being the first to advocate a railroad to the Pacific Coast is in dispute. No doubt the idea occurred to many at the time they were being introduced and successfully operated in the East. The two items referred to seem to be the first record of the idea or possibility.
