Ridges Sands ', San-lung sha 三 龍 沙.⁷ The reference in the Wei lio makes it clear that
these designations were applied to the northernmost offshoots of a belt of high sand dunes which
the caravan track coming from Tun-huang crosses, just as did the ancient Lou-lan route, a short
distance to the north-east of Bēsh-toghrak (Map No. 35. B, c. 4). Now our surveys of 1914 have
established the fact that the big south-eastern bay of the ancient sea extended continuously within
the ' Bēsh-toghrak valley ' as far as the vicinity of Yantak-kuduk (Map No. 35. A. 4). Thence
a succession of shōr-covered areas or actual salt bogs extends in the same depression close to the
west of the wells of Bēsh-toghrak (Map No. 35. A. 4; B. 3, 4). The accuracy of the statement in our
passage as to the limits of the region with which we are concerned is thus vindicated by plain
topographical facts.
It is not possible for us to test in the same conclusive fashion the statement made at the begin-
ning of the passage : 'This region has an extent of a thousand li ;' for we are not definitely told
the direction to which this measurement applies. But it is noteworthy that the recorded
estimate agrees remarkably well with the distances measured along either of the two possible
routes by which a traveller starting from the northernmost point of the ' Three Sands ', east of
Bēsh-toghrak, could attain the nearest habitable ground beyond the western extremity of the
sea-bed. As long as the Lou-lan area received water from the Kuruk-daryā and was capable
in places of human occupation, the western edge of the great salt waste which the Chinese knew
by the name of P'u-ch'ang or Yen-tsé, 'the Marsh of Salt', might be reached at two different
points, either by proceeding to Lou-lan by the ' route of the centre ' or else by following the still
practicable caravan track to Mīrān along the southern shores of the sea-bed.
Now the aggregate of my marches, as measured by cyclometer from L.J., the last outpost
of Lou-lan, to the northernmost of the ' Three Sands ' east of Bēsh-toghrak, along what I believe
to have been the approximate line followed by the ' route of the centre ', amounted to 199 miles.⁸
If the traveller were to start from the same point east of Bēsh-toghrak and to take the southern
route still followed by caravans between Tun-huang and Mīrān, a total marching distance of
practically identical length, as measured by us with the cyclometer in February, 1907, viz. 198
miles, would bring him to Camp 143 of our second journey. Near this we came upon the extreme
south-western edge of the hard salt crust area of the ancient sea-bed. From there to the west
towards Mīrān, desert vegetation in gradually increasing proportion is found along the track,
and the region of bare salt, clay, or gravel is definitely left behind.⁹ Experience gathered on my
explorations in the Tārīm basin and adjacent regions has abundantly proved that one mile there
may ordinarily be reckoned as equivalent to 5 li in Chinese records of distances over level ground.¹⁰
Thus from whichever of the two routes the measurement of a thousand li might have been derived
by Li Tao-yüan's authority, this estimate of distance would appear surprisingly correct.
For two reasons it seems to me more probable that the recorded estimate of extent was taken
from the Lou-lan route. In the first place the whole of the topographical data mentioned in Li
Tao-yüan's notice relates to the ground traversed on this route.¹¹ Secondly, we have in the conclud-
