It has occurred to me since that these far-off Mesas were probably identical with the belt of eroded
terraces on somewhat higher ground which Lāl Singh's survey shows to the west of his camp
C. 89 (Map. No. 32. B. 2).⁷ As we proceeded the Yārdangs sank away rapidly, and soon only light
swellings of the ground, in which abundant gypsum flakes were mingled with decomposed clay,
remained to suggest the former existence of such formations.

After covering about ten and a half miles from the Mesa where the coins were found, we reached Progress

here decided me to abandon our north-easterly course and to steer due eastwards for the point
where the fence of salt-encrusted ridges seemed thinnest. For another mile or so we still had the
benefit of an easy surface of decomposed clay. Then followed what seemed a shallow depression
covered with rows of low salt-encrusted hillocks, with flat beds of hard shôr between them. Fortu-
nately the winds had driven a thin coating of coarse dark gravel across these, thereby making the
ground less trying.

The direction of the rows of salt-covered Yārdangs was here, too, from N. 20° E. to S. 20° W. Edge of

to find a spot near the edge of the Yārdang belt where the salty ground, hard indeed but fairly
smooth, allowed men and camels to lie down without discomfort, after the day's total march of

driven into the surface of salt.

Much of the night had to be spent by the men in 'resoling' those camels which had again View of

level plain. Only a few isolated knolls rose island-like slightly above it far away in the distance.
Through powerful glasses it was just possible to make sure that these were the tops of hills, mani-
festly those with which the low desert ranges of the westernmost Pei-shan abutted on the huge
dried-up basin. It was encouraging to point to them as affording assurance that 'land' was in
sight, however long the difficult crossing before us might prove. To the north and north-east
a continuous fringe of low hills showed above the horizon, very distant also, yet confirming my
belief that the ancient route—which from evidence discussed below I knew to have crossed the
sea-bed—could not be sought for much farther to the north than the point where we stood. On
ground like this it seemed useless to search for direct evidence of the line actually followed by the
route, even if considerations of safety had allowed time for the purpose.
