There the Volga, the Ural, the Syr-darya and the Amu-darya discharge their waters without reaching the ocean, but they bring life to the rapidly desiccating Transcaspian steppes, and link together the most remote parts of Russia.
The area between the northern border of the Persian high lands and the Caspian and Aral Seas is a nearly desert low-lying plain, extending to the foot of the north - western extremity of the great Tibeto-Himalayan mountains, and prolonged east- Trans- ward up the valleys of the Oxus (Amu-Darya) and Caspian Jaxartes (Syr-Darya), and northward across the country re ior, and of the Kirghiz to the south-western border of Siberia.
From it the Oxus, or Amu, flows off to the west, and the Jaxartes, or Syr, to the north, through the Turki state of Khokand, while to the east the waters run down past Kashgar to the central desert of the Gobi, uniting with the streams from the northern slope of the Tibetan plateau that traverse the principalities of Yarkand and Khotan, which are also Turki.
KUNGRAD, a trading town of Asiatic Russia, in the province of Syr-darya, in the delta of the Amu-darya, 50 m.
The chief river of Bokhara is the Oxus or Amu-darya, which separates it from Afghanistan on the south, and then flows along its south-west border.
How far they reach up the present courses of the Oxus (Amu-darya) and Jaxartes (Syr-darya) is not known.
The southern coast is occupied by the delta of the Oxus (Phan, Amu-darya), one of the arms of which, the Laudan, forms a swamp, 80 m.
This river, as well as the Amu, conveys vast quantities of sediment into the lake; the delta of the Syr-darya increased by 134 sq.
This is, of course, due to the excess of evaporation over the amount of water supplied by its two feeders, the Amu-darya and the Syrdarya, both of which are seriously drawn upon for irrigation in all the oases they flow through.

OXUS, or AMU Darya, one of the great rivers of Central Asia.
The plateau is traversed by the Surkhab or Vakhsh, a right-hand tributary of the Amu-darya (Oxus).
Two rivers only - the Syr and the Amu - succeed in getting across the desert and reaching the Sea of Aral.
The only tributaries which the Amu retains are those whose whole course is within the highlands.
One of the most striking instances of this is the very thick Cretaceous and Tertiary deposits which cover the bottom of the valley of the Vakhsh (right tributary of the Amu) and are continued for about 300 m.
Of rain and snow fall throughout the year at Tashkent, at the base of the highlands; and the steppes of the lower Amu have less.
The tiger is met with only on the lower Amu-darya, except when it wanders to the alpine region in pursuit of the maral deer (Cervus maral).
