"As I told you the men from the east and those from the west worked toward each other from opposite ends of the country. As soon as short lengths of track were finished they were joined together. Near the great Salt Lake of Utah a tie of polished laurel wood banded with silver marked the successful crossing of Utah's territory. Five years later Nevada contributed some large silver spikes to join her length of track to the rest. California sent spikes of solid gold, symbolic both of her cooperation and her mineral wealth; Arizona one of gold, one of silver, and one of iron. Many other States offered significant tributes of similar nature. And when at last the great day came when all the short lines were connected in one whole, what a celebration there was from sea to sea! Wires had been laid so that the hammer that drove the last spike sent the news to cities all over the land. Bells rang, whistles blew, fire alarms sounded. The cost of the Union Pacific was about thirty-nine million dollars and that of the Central Pacific about one hundred and forty million dollars. The construction of the Southern Pacific presented a different set of problems from those of the Northern, but many of the difficulties encountered were the same. Bands of robbers and Indians beset the workmen and either cut the ties and spread the rails, or tore the track up altogether for long distances. Forest fires often overtook the men before they could escape, although trains sometimes contrived to get through the burning areas by drenching their roofs and were able to bring succor to those in peril. Then there were washouts and snowstorms quite as severe as any experienced in the northern country." "I'm afraid I should have given the whole thing up!" interrupted Steve. "Many another was of your mind," returned Mr. Tolman. "The frightful heat encountered when crossing the deserts was, as I have said, the greatest handicap. Frequently the work was at a standstill for months because all the metal--rails and tools--became too hot to handle. The difficulty of getting water to the men in order to keep them alive in this arid waste was in itself colossal. Tank cars were sent forward constantly on all the railroads, northern as well as southern, and the suffering experienced when such cars were for various reasons stalled was tremendous. The sand storms along the Southern Pacific route were yet another menace. So you see an eagerness for adventure had to be balanced by a corresponding measure of bravery. Those early days of railroad building were not all romance and picturesqueness." Stephen nodded as his father rose and took up his hat and coat. "I'd like to hear Mr. Ackerman tell of the early steamboating," remarked the lad. "I'll bet the story couldn't match the one you have just told."
