So you will see that a railroad to join California to the Eastern states was a great necessity and had often been talked of. Several ways to bring the iron horse puffing across the plains and up the mountains with his long train of cars had been laid out on paper. The emigrants had found that the best highway from the Missouri River to California was to keep along the Platte River in Nebraska to Fort Laramie and the South Pass of the Rocky Mountains, then by Salt Lake, and along the Humboldt and Truckee rivers, crossing the Sierras at Donner Pass. Other roads were talked of, and Senator Benton of Missouri favored a nearly straight line between St. Louis and San Francisco. Some one, in objecting to this, said that only engineers could lay out a railroad, and such men did not believe a straight line possible. The senator answered: "There are engineers who never learned in school the shortest and straightest way to go, and those are the buffalo, deer, bear, and antelope, the wild animals who always find the right path to the lowest passes in the mountains, to rich pastures and salt springs, and to the shallow fords in the rivers. The Indians follow the buffalo's path, and so does the white man for game to shoot. Then the white man builds a wagon-road and at last his railroad, on the trail the buffalo first laid out." For two or three years surveyors and explorers tried to find the easiest way to build this great overland road. Several railroad acts or bills were passed by Congress, and the California Legislature gave the United States the right of way for a road to join the two oceans. The first railway in the state was opened in '56 from Sacramento to Folsom, a distance of twenty-two miles. This was built by T.D. Judah, an engineer who had thought and studied a great deal about the overland road so much needed to bring mail and passengers quickly from East to West. A railroad convention, made up of men from the Pacific states and territories, was held in San Francisco in '59, with General John Bidwell, a pathfinder of early days, as the chairman. Here Mr. Judah gave such a clear and full account of the central way he had planned, that the convention sent him to Washington, D.C., to see the President, and to try to get Congress to pass a Pacific Railroad Bill. He had very little help in the East, but at last four men of Sacramento, Leland Stanford, C.P. Huntington, Mark Hopkins, and Charles Crocker, took an interest in Judah's plans, and in '61 the Central Pacific Railroad Company was formed. Mr. Judah went back to the mountains and studied the pines in summer and the winter snowbanks, to make sure of the easiest grades and the shortest and best way for the track-layers. He found that to follow the Truckee River from near Lake Donner to the Humboldt Desert, would mean the least work. The tunnels would be through rock, and he believed that snow might easily be kept off the track with a snow-plough.
