NOTES ON SHEET No. 36 (KHANAMBAL OR ANAMBAR)

The outermost ranges of the Āltin-tāgh
and their glacis towards the Su-lo-ho termi-
nal basin, shown in this sheet, were surveyed
mainly from the tāgh-yol or 'hill route'
connecting Tun-huang with the Lop region
and already mentioned above (Sheet No. 33).
This was followed by Rai Rām Singh in
1907 and again by R. B. Lāl Singh in 1913.
The belt of high sand-ridges fringing the
southern edge of the glacis was reached by
reconnaissances from the termination of the
ancient Chinese Limes in 1907. The tra-
verses along the 'hill route' have been
adjusted on the positions adopted for Mirān
and Nan-lu (Sheet No. 39). The obser-

NOTES ON SHEET No. 37 (KARLIK-TĀGH)

This sheet shows the surveys made along
the Karlik-tāgh, the eastern extremity of
the T'ien-shan range, and those carried to-
wards it from the south-west across the
northernmost Pei-shan desert. With the
exception of the caravan road from An-hsi
to Hāmi and some routes in 1907 on the
southern slopes of the snowy portion of the
Karlik-tāgh, all belong to the third expedi-
tion.

The positions accepted for Barkul, Hāmi,
An-hsi and Su-chou in adjoining sheets have
served for the adjustment of the several
traverses, besides the latitude observations
noted below. For two points on the Hāmi–
An-hsi caravan road latitude and chronomet-
rically obtained longitude values of other
travellers are available for control. Dr.
Vaillant's position of Yen-tun (A. 4),

vations of 1913 at Khanambal (C. 2) and
Su-mu-t'ou (D.1) have proved the latitudes
shown for these places in Sheet No. 75 of
the Serindia map as correct within about
a minute.

References regarding the historical
topography of the 'hill route' have been given
in the Notes on Sheet No. 33. The range
along which it leads is exceedingly barren
also in this section; but some modest graz-
ing is found at Khanambal, a winter
camping ground of Mongols, and at Khalas-
tai, while a little patch of cultivation exists
at Su-mu-t'ou, occupied by a couple of
Chinese families.

42° 21′,6 lat., 94° 4′,9 long., agrees closely
in latitude with that shown in the map,
while his longitude is about 2 minutes less
than on the map. At K'u-shui (B. 4) Mr.
Clementi's observed latitude is the same, but
his longitude value, 94° 26′ 25″, is exceeded
by fully 8 minutes on the map; this differ-
ence conforms to that already noted as
regards Hāmi (see sub Sheet No. 34).

It is satisfactory to note that M. Mu-
hammad Yakūb's traverse from Ming-shui
(No. 40. A. 1) to Tāsh-bulak (A. 3) shows
between his Camps clxi and clxiv very close
agreement with the careful route survey
carried by Professor K. Futterer over the
same ground. ²²
