Then came the idea of a relay of fast messengers upon horseback, and the pony express was organized. It is difficult to believe that by this means the journey of two thousand miles between St. Joseph, a point upon the Missouri a little above Kansas City, and Sacramento, California, was once made in about eight days. This is only a little more than twice the time required by the fast trains at present. For two years the trip was regularly made in about nine days, averaging two hundred and twenty miles a day. It can be readily understood that this wonderful feat required many relays of men and horses scattered along the route. The express rider had no well-graded roads to follow, but only the rough trail of the emigrants. This led across broad deserts and over rugged mountains, and throughout most of the journey exposed the rider to the attacks of Indians. Let us take a map and trace the route of the express. It followed closely the main overland trail which the gold-seekers had opened. Now towns and cities are scattered along the old trail, and the railroad crosses and recrosses it. But let us try to picture the country as it appeared in its wild state. Mountains, valleys and plains made up the landscape. Vast herds of buffalo darkened the Great Plains east of the Rocky Mountains, while farther west were numerous bands of antelope. The streams were filled with beaver and other fur-bearing animals. Here and there along the rivers were Indian villages with their curiously shaped tepees. Even the deserts of Nevada were not uninhabited, for the Indians lived there also, gathered in little family groups about the desolate springs. When we speak of the overland trail we do not mean a narrow path for animals, but the wagon road, rude though it was, which the early emigrants had made. They were determined to cross the continent, no matter what the difficulties and dangers. Wagons could be drawn by the oxen over the plains and deserts with little difficulty, although there were some dangerous rivers to be crossed. Mountains and canons offered the most serious obstructions. In many places the wagons had to be let down over precipices with ropes, or be taken apart and carried piece by piece around the obstructions. It was not the mountains alone which made the trip "across the plains" one long to be remembered. It was often difficult to obtain water and fodder for the animals, and at many points savage Indians, bent upon plunder, were in hiding, waiting for a chance to stampede the cattle or kill the emigrants. The way was marked by abandoned wagons, household goods, bones of cattle, and the graves of human beings.
