steadily downwards without eddy or back-stream, though there was a narrow belt of stationary water -under the right bank. This bank was low, with marshes and tiny pools of a score or so meters to the south of it. The opposite bank, where the huts of the village stand in two rows, is more accentuated and higher, namely

Breadth = 22.o m. Tusun-tschapghan branch, April Io. Scale I : zoo.
With the view of controlling the results I have just given, as well as of ascertaining how much of the water went to the north and how much to the south, I took the following measurements immediately afterwards in the two riverarms separately, which in plan resemble a hay-fork (fig. 98). The Tusun-tschapghan arm had a breadth of 22.o m.; a mean depth of 2.364 m.; a mean velocity of 0.3729 in.; and a volume of 19439 cub.m. in the second. The left bank, against which the most powerful part of the stream was driven, is 1 m. high, and vertical, and farther down rises slowly up towards some old dunes, bound together with vegetation; consequently they are contained between the two river-arms, and thus serve as a memorial of the time when the drift-sand was able to spread freely westwards in this part of the country as well. The right bank rises into a low rampart, behind which, on the south, are marshes.

Breadth = 22.6 m. Kum-tschapghan branch, April Io. Scale I : 200.
The Kum-tschapghan arm on the left had a breadth of 2 2.6 m. ; a mean depth of 1.243 m.; a mean velocity of 0.3055 m.; and a volume of 8.58 m. in the second. Here the left bank ascends to the highest dune-hill, bound by vegetation, that there is in that region, its altitude being 10.24 m.; but the right side of the stream is occupied by a silt-deposit at the very verge of the water. This applies however
