VOLUMES OF THE TARIM, JURT-TSCHAPGHAN AND KUM-TSCHAPGHAN. 153
At the present moment there is no Abdal that is inhabited, for the district around the existing village has long been called Jurt-tschapghan. But even this situation appears to be in danger, for it is surrounded on every side by marshes and lakes.

Breadth = 30.o m. Tarim at Kum-tschapghan, April io. Scale 1 : 400.
Measuring the river at Jurt-tschapghan on 13th April, I obtained the following result — breadth, 42.4 m. ; mean depth, 3.365 m. ; mean velocity, 0.6023 m. in the second; and volume, 85.91 cub.m. in the second. I have already stated, that at Schirge-tschapghan on 19th April the river had a volume of 101 .86 cub. m. in the second, or 16 cub.m. more than at Jurt-tschapghan, although the measurement there was made six days later, at a time when as a rule the river is subsiding, and without taking into account the influx of the Tschertschen-darja, though it was then, I admit, insignificant, for its spring-flood does not get down to these lakes until the early summer. The difference of volume was unexpected, because the river gives off no canals above Jurt-tschapghan. It must therefore be accepted as a proof of the enervation which overtakes the Tarim before it reaches the Kara-koschun, an enervation which can only be ascribed to the extremely heavy evaporation that goes on, conjoined with the absorption of the water into the ground.

Kum-tschapghan the river had the following dimensions — breadth, 30.0 m.; mean depth, 2.601 m.; mean velocity, 0.3363 m. in the second; and
volume, 26.24 cub.m. in the second.
These data were obtained just above the point where the river divides, and where the water was flowing
