sandstone, intermixed with lumps of rock salt.⁷ The neighbouring spurs of the Kum-tāgh seemed
to be of the same formation, and the foot of the hill-side was everywhere seen to be studded with
shallow pits, the result of salt-digging operations. The point is known as *Tuzluk* ('the salt place')
and marked by a couple of reed huts. Beyond this we continued across the bare inundation belt
by the side of the lake, which, towards its southern extremity, shrunk considerably in width and
split up into a series of lagoons between extensive reed-beds (Map No. 8. B. 2).
Filling of
water-
tanks, &c. The statement of Azīz 'Pāwān', that on a hunting trip the year before he had found there
drinkable water, induced us to pitch camp amidst tamarisk-cones not far from the southernmost
of these lagoons. But the water proved decidedly brackish, probably because the lake reservoir
had not been sufficiently refilled by the last summer flood, and next day we had to move back with
the camels some six miles before fresh water was found by the lake shore wherewith to fill tanks
and skins for the journey. As the water was very shallow and the men had to wade far out, it took
practically a whole day's work to fill, secure, and load up our six galvanized iron tanks and the
forty-two goat-skins brought from the 1st Sappers and Miners' Workshops at Roorkee.
First dunes
encoun-
tered. On October 29th we set out to the south-east after a start delayed by the packing and dis-
tribution of the heavy loads of water. For three miles we crossed bare salty soil, marking a former
extension of the lake end, now dried up. Then the first dunes were reached, stretching in irregular
lines across flat ground of disintegrated loess dust, covered on its surface with abundant remains
of quasi-petrified reeds and scrub. On this ground, which extended for about another three miles
and obviously marked a former riverine belt, living vegetation was entirely absent. Farther on
the dunes increased in height to thirty feet or more, and lay much closer together. Yet scanty
living tamarisk scrub appeared again between them, and in a small depression we found even
a group of young Toghraks rising above the sand. Their presence encouraged the hope that
subsoil water was near, and on pitching camp here, a well dug to a depth of about four feet sufficed
in fact to reach it. When the march was resumed next morning we found the dunes growing rapidly
higher and very closely packed. The crests of individual dunes here faced with their concave sides
regularly to the south-south-west. But the huge ridges or 'Dawāns' into which they lay heaped
up, and which we soon encountered rising in endless succession to heights of 200-300 feet, were
found to run invariably with an approximate bearing ENE.-WSW. Their lines thus lay at a
fairly wide angle diagonally across our intended direction, and consequently involved constant
ascents and descents, both very trying to the camels.
Direction
of sand
'Dawāns'. It soon became evident to me that this uniform bearing of the 'Dawāns' was a result of a law
that I had previously observed in the desert west of Lou-lan, in the Keriya river delta, and else-
where, under the action of which these big accumulations of drift-sand in the Taklamakān are
aligned parallel to the main direction of the nearest large river.⁸ But there were important differ-
ences to be noted here and there distinctly unfavourable to us. In the areas of high sands previously
crossed by me these 'Dawāns' had not presented themselves as unbroken chains such as faced
us here, but as separate ridges varying in length, yet always showing at their ends low saddles or
shoulders over which movement with laden camels was comparatively easy. The steering round
those 'Dawāns' had indeed compelled us to make considerable detours; but the broad and flat
valley bottoms found between them afforded easy ground, and the march across it served to give
relief to the camels.
Difficulties
of progress
across
Dawāns. The tract now encountered offered obstacles far more formidable in all respects. To get round
the 'Dawāns' was impossible, for nowhere did they show distinct saddles or breaks. To move
