Michie, another traveller, gives in brief the general method of the Russian advance. It will be seen to be similar to that by which the Indian lands of the western United States were gained. "The Cossacks at Russian stations make raids on their own account on the Kirgheez, and subject them to rough treatment. An outbreak occurs which it requires a military force to subdue. An expedition for this purpose is sent every year to the Kirgheez steppes. The Russian outposts are pushed farther and farther south, more disturbances occur, and so the front is year by year extended, on pretence of keeping peace. This has been the system pursued by the Russian government in all its aggressions in Asia." But this does not tell the whole story of the Russian advance in Asia. South of the Kirghis steppes lies another great and important territory, known as Central Asia, or Turkestan. Much of this region is absolute desert, wide expanses of sand, waterless and lifeless, on which to halt is to court death. Only swift-moving troops of horsemen, or caravans carrying their own supplies, dare venture upon these arid plains. But within this realm of sand lie a number of oases whose soil is well watered and of the highest fertility. Two mighty rivers traverse these lands, the Amu-Daria--once known as the Oxus--and the Syr-Daria--formerly the Jaxartes,--both of which flow into the Sea of Aral. It is to the waters of these streams that the fertility of _the_ oases is due, they being diverted from their course to irrigate the land. Three of the oases are of large size. Of these Khiva has the Caspian Sea as its western boundary, Bokhara lies more to the east, while northeast of the latter extends Khokand. The deserts surrounding these oases have long been the lurking-places of the Turkoman nomads, a race of wild and warlike horsemen, to whom plunder is as the breath of life, and who for centuries kept Persia in alarm, carrying off hosts of captives to be sold as slaves. The religion of Arabia long since made its way into this land, whose people are fanatical Mohammedans. Its leading cities, Khiva, Bokhara, and Samarcand, have for many centuries been centres of bigotry. For ages Turkestan remained a land of mystery. No European was sure for a moment of life if he ventured to cross its borders. Vambery, the traveller, penetrated it disguised as a dervish, after years of study of the language and habits of the Mohammedans, yet he barely escaped with life. It is pleasant to be able to say that this state of affairs has ceased. Russia has curbed the violence of the fanatics and the nomads, and the once silent and mysterious land is now traversed by the iron horse.
