To overcome the shifting of the sand, near the Caspian it was thoroughly soaked with salt water, and at other places was covered with a layer of clay. But there are long distances where no such means could be employed, at least two hundred miles of utter wilderness, where the surface resembles a billowy sea, the sand being raised in loose hillocks and swept from the troughs between, flying in such clouds before every wind that an incessant battle with nature is necessary to keep the road from burial. To prevent this, tamarisk, wild oats, and desert shrubs are planted along the line, and in particular that strange plant of the wilderness, the _saxaoul_, whose branches are scraggly and scant, but whose sturdy roots sink deep into the sand, seeking moisture in the depths. Fascines of the branches of this plant were laid along the track and covered with sand, and in places palisades were built, of which only the tops are now visible. Yet despite all these efforts the sands creep insidiously on, and in certain localities workmen have to be kept employed, shovelling it back as it comes, and fighting without cessation against the forces of the desert and the winds. In the building of the road, and in this battling with the sands, Turkomans have been largely employed, having given up brigandage for honest labor, in which they have proved the most efficient of the various workmen engaged upon the road. Aside from the peculiar difficulties above outlined, the Transcaspian Railway was remarkably favored by nature. For nearly the whole distance the country is as flat as a billiard-table, and the road so straight that at times it runs for twenty or thirty miles without the shadow of a curve. In the entire distance there is not a tunnel, and only some small cuttings have been made through hills of sand. Of bridges, other than mere culverts, there are but three in the whole length of the road, the only large one being that over the Amu-Daria. This is a hastily built, rickety affair of timber, put up only as a make-shift, and at the mercy of the stream if a serious rise should take place. The whole road, indeed, was hastily made, with a single track, the rails simply spiked down, and the work done at the rate of from a mile to a mile and a half a day. Before the Bokharans fairly realized what was afoot, the iron horse was careering over their level plains, and the shrill scream of the locomotive whistle was startling the saints in their graves. Over such a road no great speed can be attained. Thirty miles an hour is the maximum, and from ten to twenty miles the average speed, while the stops at stations are exasperatingly long to travellers from the impatient West. To the Asiatics they are of no concern, time being with them not worth a moment's thought.
