perfectly straight across the gravel-covered flat and rising from three to four feet above it.⁶ It
exactly resembled the remains of the Limes wall where traced in its completely decayed state to
the east of T. xxvi.⁷ In the light of the setting sun, I thought I could also recognize the slight
depression left in the gravel by an ancient track keeping parallel to the wall line and at a distance
of about nine yards south of it. I had previously noticed a similar depression along more than one
stretch of the Limes west of Tun-huang.⁸
The necessity of reaching water before nightfall prevented any search along the line of the Approach
wall and obliged us to hurry on towards the Su-lo-ho across the bare Sai. At a distance of about to Su-lo-ho
a mile and a half we came upon a clearly marked dry river-bed, about 20 yards wide and lined with bed.
Toghraks, most of them alive. Its appearance and direction left no doubt that it was the same
that I remembered having crossed when making my way seven years before to the Su-lo-ho from
the easternmost portion then traced of the Tun-huang Limes.⁹ Beyond it came a narrow strip of
ground where the exposed clay was cut up into regular small Yārdangs, 4 to 5 feet in height ; and
after this again, level gravel-covered Sai, with only scattered tufts of thorny scrub and here and there
a few old Toghraks surviving. There was nothing to assure us that we were approaching the eagerly
expected river, until we almost stumbled upon its deeply sunk bed, fringed by a narrow belt of
reeds and young Toghraks.
The place we had reached for the night's camp showed signs of having been frequented from Search for
time to time by men grazing camels or collecting fuel. A rough cart-track was found in the morning Limes wall
leading from it in the direction of An-hsi. This we followed for close on eight miles eastward to SSW.
where a large refuse mound, rising to a height of about 8 feet, indicated the former existence of
some regular halting-place. Experimental digging disclosed only layers of stable refuse and left
it doubtful how long it had been abandoned. From this point the baggage was sent on ahead,
with instructions to camp by the river, while Afrāz-gul and I, with a iew men, set out to the south-
south-west to search for the line of the Limes. At a distance of two miles from where we had left
the cart-track, we again crossed the winding river-bed previously mentioned. Its general course
lay here from the south-east, and this direction was confirmed by subsequent observations, as
Map No. 38. D. 4 shows. I am thus led to conclude that this dry bed probably represents the
continuation of the course followed by the T'a-shih river where it turns sharply to the north to lose
itself on the flat of the Su-lo-ho valley.
On both sides of this old flood-bed the alluvium once deposited by it was furrowed by wind- Belt of
erosion into Yārdangs. Here they were only 2 to 3 feet high ; but at points farther to the east, Yārdangs.
where we subsequently had occasion to cross this eroded belt along the dry river-bed, the Yārdangs
rose higher—up to 8 to 10 feet. As we continued our march to the south, the bare Sai of gravel
crossed on the previous evening stretched again before us. But in spite of remarkably clear atmo-
spheric conditions, which allowed us to sight the successive ranges of the Nan-shan right away to
the snowy chain south of Shih-pao-ch'êng (Map No. 39. D. 1 ; 41. A, B. 1), no ruined towers of the
Limes could be seen. Nor did we, owing to the sun being high and in our face, notice the straight
line marking its agger until we were quite close upon it.
We there found that the low gravel mound into which it had decayed ran straight like a rail- Gravel
way alignment, with the approximate bearing from east to west. Where we first struck it, the mound mound
rose to a height of only 4 feet above the level of the bare gravel, but showed a width of about marking
32 feet at its foot. No remains of fascines or other reinforcing material were traceable on the surface. Limes wall.
