7 4 HISTORY OE1 SURVEYS [Chap. I
Having moved uorth to Pirha, I sent the surveyor to follow 11 new route to Khotan
skirting eastuvar(1o: the slopes of the Tilrelik-tfigl~ ( 18,7S0 feet ), while
for 1 ~iiyself proceeded there by the direct route, already surveyed ill 1900,

in order to gain time for multifarious preparations for the desert campaign
of the autumn and winter. On September 15th I set out for a series of ruined sites to the
north-east aud east of the Khota~r oasis. At the same time Rim Singli was sent off
indepeudently to the foot of the main K'un-lun range south of Keriya in order to resume his
survey work where it had stopped in December 1900 near Imimlar ( Tort-Imim ), and to
extend his tria~~ulrtion along the northern n~ain range of the K'uu-luu as far as possible
eastwards.
Having gained Imimlar cin Keriya, Rim Singli was able to utilize for his hill survey
to the soutli and sooth-east the points tixed by his triangulation of 1900
K.~~~'u~~~~~;~~~~II as well as a llt~mber of high peaks on the spurs above the gorges of
Pdlur which Captain Deasy's triangulation had determined in 1898-99."
He the11 lueasured a base for t,riangulation above the hill village of Aclichan furtllcr east
(Sheet No. 14. D. 4.1, connecti~~g it nvith t,no of Captain Densy's points. I~~formation as
to the detern~iuatioli of this base and the niethotls by n7liich the triangolation there started
was ~uccessfully extended to the east, first as far as Snrghirl;, south of Kiya, and subsequently
beyond Charchau to a peak in longitude 86" 46' (Sheet No. 27. B. I), will be found
in Major hIason's Appendix A. The total lengt,h of new triangulation work thus accomplished
by Rim Sing11 along the K'un-lun range extended over five degrees of longitude.
After completing archieological explorztio~ls in the deseit north of the Khotan-Keriya
line, partly on ground not previously surveyed, I reached the Niya oasis

was able to fix the position of the small marltet-town of Niya by means of triangulation from
the K1un-lun. It is the first and so far only instance of an oasis on the edge of the great
desert having t,hus been exactly located. From Niya he acc~mpanied me to the ancient
sand-buried site beyond the terniination of the Niya river first visited by nie in 1901. There
