But in a few short days the beauty has disappeared. The seeds mature speedily and drop into the sand. A hot wind withers the stems and leaves and blows them away; drifting sands take the place of the rich carpet. How readily these plants have adapted themselves to the brief period in which life is possible!

Thus it is that this vast region about the lower Colorado, although so dry and hot, and at first sight apparently so unfitted for sustaining life, nevertheless supports its share. Many of the plant forms have assumed strange and monstrous shapes in their efforts to withstand the hard conditions in the struggle for existence, while others simply lie in waiting, sleeping during the long dry year, but ready to spring into life when the favorable showers come, as they sometimes do.

[THE PONY EXPRESS]

although it is only a little more than fifty years since the discovery of gold was made and the rapid settlement of the West began, what a change has come over this great region! It was at first supposed to be impossible to connect the growing settlements upon the Pacific with the East by anything more than a wagon road, and those who advocated the building of a railroad were ridiculed. Now the journey across the continent is made upon smooth steel tracks in comfortable coaches, for the skill of the engineer has overcome the difficulties of the desert, the mountain wall, and the cañon.

The pioneers who pushed westward from the Mississippi River with their slow ox-teams took all summer to reach the fertile valleys of California and Oregon, and considered themselves fortunate if they arrived at their destination before the coming of the winter storms.

The first overland stage line was established by way of New Mexico and Arizona, terminating at Los Angeles. Twenty-two days were required for this part of the tiresome and dangerous trip. The route was longer and more desert-like than that farther north across Nevada, but the winter storms were avoided.

The stage-coach proved too slow for the needs of the growing settlements upon the Pacific slope. A telegraph line was planned, but it could not be completed for some time, and even then it was probable that the Indians would destroy the poles and wires.

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.
