The above incidents are but a few out of thousands that occurred during the stormy construction days. They illustrate the trials and dangers encountered by the hardy pioneers. It was not only at "the front" that trouble was incurred, but after the building had proceeded, the section men, station employees and train crews were in constant danger. At the stations, it was a rule to build sod forts connected by underground passage with the living quarters to which retreat could be had in case of Indian attacks. For some time small squads of soldiers were stationed at every station and section house along the line, being quartered in sod barracks. With the completion of the road and the establishment of regular train service, immigration soon poured in to such an extent as to make the settlers numerous enough to protect themselves, and it was not long until "Lo," like the buffalo, was only a memory. CHAPTER VII. _The Builders._ Their Material and Methods--Oakes Ames (Financier)--George Francis Train (Promoter)--John A. Dix (First President)--Thomas C. Durant (Vice President and President)--Granville M. Dodge (Chief Engineer)--Subordinate Officials--Casement Brothers, Track-layers, Mormons--Materials Used--Their Source--Methods. At Sherman Station, the highest point on the Union Pacific Railroad, stands a monument some sixty feet square and about the same height, bearing the simple legend, "In Memory of Oakes Ames and Oliver Ames." This was erected in compliance with a resolution passed at the meeting of the Company's stockholders held in Boston, March 10th, 1875, which read as follows, "Resolved that in memory of Oakes Ames and in recognition of his services in the construction of the Union Pacific Railroad to which he devoted his means and his best energies with a courage, fidelity, and integrity unsurpassed in the history of railroad construction, the directors (of this Company) are requested to take measure in co-operation with such friends as may desire to contribute, for the erection at some point in the line of the road, of a suitable and permanent monument." (By the recent shortening of the line this monument has been left some three miles away from the present track. Its removal to Cheyenne Depot Grounds or some other equally prominent position is under consideration.) Oliver Ames was born at North Easton, Mass., January 10th, 1804; he passed his youth and early manhood assisting his father in the work of a farmer and later of manufacturing shovels, attending during the winter a country school. Serving first as apprentice, then foreman, he was in due time taken into partnership with his father to whose business he succeeded.
