| On the morning of May 10, 1869, a gang of Irish immigrants met a party of Chinese laborers on a windy bluff northwest of Salt Lake City, Utah. Tired to the bone, the two groups laid down the last of countless wooden ties, bought at the exorbitant cost of six dollars apiece, and thus joined two great rail lines, the Union Pacific and the Central Pacific, to form a single transcontinental route. That rail line made possible the mass settlement of the West, and, as those who conceived it well knew, it changed the course of American history. |
