THE SYR-DARIA

temperature 2i°9 Fahr. (-5°6 C.), I made the following- 
observations in the Naryn. 
The mean depth was 5ft. 10 in. (maximum 8 ft. 7 in.) ; the 
area of the vertical section 840 square feet ; mean velocity 
3 ft- 8 in. (maximum 4 ft. 6 in.); and the volume of water 
3070 cubic feet. The greatest depth and the greatest 
velocity occurred on the right side of the river ; and there, 
too, the stream was loaded with large quantities of packed 
Jce. The greatest quantity of drift-ice I found in a 
current only 1 2 yards from the right bank ; thus it did 
not follow, as might be expected, the swiftest current, 
which was 25 yards out from the same bank. 
About one mile to the south, I crossed the Kara- 
ana about a couple of hours later, and I then made 
he tollowmg observations in that river mean depth 
5 t. 3in. ; maximum depth 10 ft. 1 1 in. ; area of vertical 
section 1220 square feet; mean velocity 3 ft. 10 in. 
(maximum 4 ft 6 in.); volume of water 4700 cubic feet. 
ogether, therefore, the Naryn and the Kara-daria 
carried 7770 cubic feet of water, or almost precisely the 
quantity I found in the Syr-daria at Gurum-serai 
Comparing the two streams, it will be found that the 
Karafoaria IS 9 ft. broader than the Naryn, but as a 
rule IS shallower, while the maximum depth is o-reater 
In both rivers the maximum depth is near thj rio-hi 
\ both the right 
bank IS much more eroded than the left. It is also higher
