Within Russian territory the Murghab river irrigates exclusively the Merv district, and its length within the Trans-Caspian province is about 400 versts. If its numerous bends were taken into account the length of the stream would be 850 versts. The Kushk river waters Russian territory for a distance of 100 versts, from the Russo-Afghan frontier to its confluence with the Murghab; the Kashan for 60 versts. The width of the Murghab at the Kaushut-Khan-Band, 28 versts above the town of Merv, is about 23 sagenes; but at Merv itself it narrows to 12 sagenes. Its mean depth is 7 feet. The rise of the water begins in the middle of March and the fall finishes three months later. Between June and the middle of October the level of the river is determined by the rain-fall and snow in the neighbouring mountains. About June, when the river has fallen, the population experiences the want of the water which is necessary for the autumn crop of cotton. In years of drought, when the dearth of water is felt much earlier--during the period of the ripening of the crops, in fact--the population are obliged to abandon the greater portion of their harvest. The country through which these rivers flow is, in the main, a mixture of desert waste and cultivated strip, with rising uplands carpeted in spring by bright flowers and hidden in winter by heavy snows. Roads meander along the valleys, sometimes by means of rocks and boulders crossing and recrossing the stream many times in short stretches or, at others, wandering far away from the waterside to traverse the broken spurs of hills. Where signs of cultivation exist, there are indications that the population has regained confidence in the Russian domination of the district. Fields and irrigation canals have been cleaned and restored; the sparkle of the little rills is reflected in the brilliant sunshine. [Illustration: TAMARISK SCRUB IN THE RIVER VALLEY]
