Upon the passage of the supplementary Charter in 1864 the restriction confining the Central Pacific to the State of California was withdrawn and they were authorized to build for one hundred and fifty miles east of the California boundary. This latter restriction was also withdrawn by Congress in 1866, leaving the meeting point to be determined by the rapidity of the construction of the respective lines, or as the Act of Congress put it, they could locate, construct, and continue their line until it should meet the Union Pacific continuous line. With the experience of three years behind them and the Land Grant, Government Bonds and prospective earnings, not to speak of the element of pride ahead, the two lines entered into a race the like of which had never been seen. The rivalry extended from the Presidents of the respective Companies down to the boy who carried water to the graders. Both forces, justly proud of their achievements, considered themselves a little better than the other. One form of the rivalry was as to which outfit could get the greatest amount of track down in one day. The Union Pacific's forces led off with six miles, soon after the Central went them a mile better. Then seven and a half miles were put down by the Union Pacific; the Central Pacific forces not to be outdone announced they could get down ten miles inside of one working day. Vice-President Durant offered to wager ten thousand dollars it could not be done, and the Central Pacific outfit resolved it should be done. Waiting until there were but fourteen miles for them to lay, they started in and laid ten miles and two hundred feet from seven A.M. to seven P.M., using four thousand men in the operation. And then the Union Pacific outfit was mad. They claimed if they had massed their forces, made special preparation, etc., they could do better than their competitors, but they could not prove it for there was no more track to lay.
