THE TARIM RIVER.
banks are often distinctly perceptible for some distance into the forest. As in these places the river's erosive energy is more active, there results a considerable hollow below the banks, giving them an appearance of more than the usual altitude and substantiality. In the deepest parts of the lagoons there is generally a little pool of water (jarsik) remaining until the next high-flood season. Very often it is impossible to determine whether what one sees is a boldschemal or a jarsik.

At the next bend we found a small lake well stocked with fish. Old forest was still abundant, and young forest also was common. At Ketmen-kaldi there is a small jarsik on the left bank, set about with low dunes, and immediately below it yet another. In fact, these formations are very numerous all along this part of
the river. On the opposite bank we have Mus-asti, i. e. Mungus-asti, or the Suspended Horn.

Scale 1 : zoo. the following dimensions: — breadth, 4.80 m. ; mean
depth, 0.363 m.; mean velocity, 1.1798 m.; volume, 2.06 cub.m. in the second. On the 18th April this same channel had a volume of 2.44 cub.m. Its hydrographical importance will be analysed and discussed in another connection. Passing Jalghus-jigdedake-uj on the left, and on the right Kurban Supatschapghan, Sokuschghan, and the jarsik of Jangi-köl, with its good fishing-grounds, a product of the river's overflow, we pulled up in a loop, the isthmus of which was only a few meters across, conveying the impression that it could not much longer escape its inevitable destiny. The river gave here the following measurements — breadth, 47.23 m.; mean depth, 1.887 m.; mean velocity, 0.6887 m.; volume, 61.38 cub.m. in the second. Thus since the I 9th April it had lost no less than 4o cub.m.; for on the date last mentioned I obtained the following measurements — breadth, 47.6 m.;
