and all the channels which enter it are, without exception,
lqtt quite dry ; it is really a hydrographic system of beds
isi4 without water. But though the land now lies dry and
04 lifeless, and though one listens in vain for the sound of
101, purling water, yet there is water beneath the dry dark
roii crust, and turbid flood streams foam along the furrows
after heavy rain. It is a rare occurrence, and the beds
dry up again after the rain has ceased, wind and weather
begin again to do their part, and after the next rain all the
I
fine material is washed down into the Kevir and helps to
fill up the depression. In the region where I now first
14` made acquaintance with a true kevir, its surface is as level
as a lake—on the whole, of course, without reference to
small inequalities. It may then be concluded that these
low regions are a bed of mud, a viscous mass with a sur-
face which, like that of other fluids, assumes a horizontal
position. When fresh mud is swept into the Kevir it
forms no elevations but spreads out evenly and horizontally.
)14 It may also be taken for granted that the yellow belts
which seem to be firm and more dried up are but ephemeral
phenomena, which change their appearance and consistency
rot after heavy rain. And sometimes we pass over belts as to
which it is difficult to decide whether they belong to the
Kevir or to the firm dry steppe land, as, for example, when
odQ the yellow soil has been superficially covered with fine
pebbles by a heavy flood. Only when steppe plants grow
among such gravel can we say for certain that we are on
solid steppe land.
The shore, or the flat strip of steppe, is usually i oo,
seldom 200, yards broad, and we have the front of the hills
on the right hand and the Kevir on our left.
We had twice heard of a path which ran from the south
5 to the spring of Mulkabad, and this path, if it were not
quite obliterated in the insecure ground, was our hope.
Should we find it we should be able to cross the Kevir,
but, if not, then we might be forced to travel westwards
to the neighbourhood of Kum ; and I had also pondered
if it were not wiser to start from Hauz-i-sultan, Kum, or
Kashan. But now we had come straight to the Kevir,
and we must work our way through it somehow.
