before reaching the next traceable remains of a watch-tower, T. xxxvii. d. This had decayed into Line of
a small shapeless clay mound ; but the semicircle which the wall made round it, with a diameter Limes agger
of 50 yards, rendered its position quite certain. traced to
T.xxxvii. e.
From here onwards we found rows of low Yārdangs approaching close to the line followed
by the Limes. Their axis lay almost due east and west, whereas the Limes agger followed an
alignment of S. 97° E. It was here reduced once more to the condition of a low gravel-covered
mound. In this form we managed to trace it to another completely decayed tower, T. xxxvii. e,
and thence for about three-quarters of a mile farther, until we lost it in a belt of closely packed
Yārdangs flanking the old river-bed previously mentioned. At this point the late hour and our
distance from the river where we should have to look for the night's camp obliged us to suspend
our search. But the sight of a ruined tower to the north-east showed us where to resume it next
morning.
From Camp cxxv, which we were lucky to be able to locate and reach after nightfall, as it Patch of
was pitched low down by the river, I started back on April 12th, Easter Sunday, to the Limes abandoned
line. While moving with the baggage towards the previously noted cart-track which it was to cultivation.
follow to the western edge of the An-hsi oasis, we came unexpectedly, after proceeding a mile or
so amidst luxuriant scrub, upon a small area of abandoned cultivation. The canal that once carried
water to it from the east was still clearly traceable, and as no wind-erosion had as yet set in on the
fields, the date of abandonment could not be remote.
The tower, T. xxxvii. f, sighted on the preceding evening, was at once shown to be old by the Ruined
abundance of pottery debris of Han type found lying about its foot. It still rose to a height of some Limes
18 feet and measured about as much on each side of its square base. Its construction was unusual ; T.xxxvii. f.
for fissures in the mass of stamped clay showed that this formed only a kind of outer casing for
a core of natural clay. An isolated erosion terrace, about 10 feet in diameter and of irregular
shape, had apparently been utilized for building this watch-post. In order to secure cohesion,
wooden beams had been fixed into square holes cut into the natural clay, and then the stamped
clay had been built up around the beams. The latter, as well as smaller pieces used for this wooden
reinforcement, still survived. But their very rotten condition was plain indication of climatic
conditions less arid than those to which the Limes remains west of Tun-huang bore witness. On
clearing the top of the tower the natural clay emerged and showed by its red colour that signal-
fires had been kept burning there. The only refuse traced near T. xxxvii. f consisted of a heap
of brushwood, mainly small twigs, such as occurs in the agger of this section of the Limes, and
some animal bones.
At first the position of this tower appeared distinctly puzzling. To the south-west of it no Puzzling
clear alignment could be made out connecting it with the agger traced to T. xxxvii. e. The ground position of

up here and there. To the north of the tower, however, I noticed that a broad dike-like bank of
gravel, about 70 feet across at its foot and for the most part 15 to 16 feet high, started at a distance
of about 50 yards and extended in a slightly curving line eastwards for about a mile. It looked
very different from any part of the Limes wall I had traced so far, but somewhat resembled the
broad gravel embankment which in 1907 I found running across the bare Sai from Nan-hu to the
Tun-huang river.¹²
Feeling uncertain about the relation between this strange-looking gravel dike and the tower
T. xxxvii. f, I at first considered it possible that the latter might have been intended merely as an
advanced post for observing the ground otherwise screened by the dike, perhaps of earlier origin,
