Mesas showed in striking contrast above them. They seemed far away and probably only their

tops were visible ; but the distance could not be determined as farther on we lost sight of them.

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 Lal Singh's survey shows to the west of his camp

C. 89 (Map. No. 32. B. 2).' As we proceeded the Yârdangs 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

the east a continuous line of the familiar white salt-coated ridges. It could be seen stretching far

away to the north-east, and is, I think, probably connected with the Yârdang belt which Lai

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 Mar 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 Yârdangs was here, too, from N.20° E. to S.20° W. Edge of

to find a spot near the edge of the Yârdang 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

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.
