SUMBAR— Lat. 37° 52' 0", Long. 55° 2(T O'' ; _Elev. ^ ' {Napier),
A tributary of the river Atrak, which it joins at Chat, about 100 miles
from its mouth. In the upper part of its course it bears the name of the
“ Sunt ” river. Its general course is along the bottom of a steep-sided ravine,
the bed of which is more or less flat; and in its midst is the river channel,
varying in width from a few feet to 20 or 30 feet. It generally contains
but little water; and in April at its junction with the Atrak at Chat it is
said to have little more than a foot of water, and to be crossed by an easy
jump. From the size of the ravine, however, and from the dimensions of
the channel itself, it is probable that, at times, the mass of water must be
very considerable.
Small as is the usual quantity of water in the Sumbar, the river presents
an almost insuperable obstacle to beasts of burden, and especially to camels,
even when not laden. This is due to the sides of the river sloping regularly
at an angle of 45°, and owing to the slippery nature of the loamy soil
when moistened, which then resembles a soaped board, and renders it almost
impossible to get out of the water without assistance, or even to stand
in the water within one's depth, as the sides slope together in V form.
The water of the Sumbar is considerably more saline and charged with silt
than that of the Atrak.— {O’Donovan.)
