On issuing from Kara-buran the Tarim again appears as a river of some importance, but it soon rapidly diminishes, owing to the numerous canals by means of which the inhabitants draw off the water for fishing purposes. On the opposite bank the neighbouring desert continually encroaches upon the land capable of cultivation, scorching with its fiery breath every spare drop of moisture, and finally arresting the further progress of the river eastward. The struggle is over, the desert has gained the mastery over the river, life is swallowed up in death.
