finally effected our passage through the Richthofen range
(Fig. 4) over a succession of high transverse spurs to the city
of Kan-chou. The total mountain area covered by our
plane-table survey between An-hsi and Kan-chou amounted
to close on 24,000 square miles.

Seven years later, in the summer of 1914, my third ex-
pedition brought me once again to this large city of Kan-
chou and the great oasis at the foot of the Nan-shan of
which it is the centre, just as in the days when Marco Polo
stayed there. It was to serve as our base for the new surveys
which I had planned in the Central Nan-shan. Their object
was to extend the mapping which we had effected in the
high mountain near the sources of the Su-lo-ho and Su-
chou rivers by surveys of the high ranges farther east con-
taining the headwaters of the river of Kan-chou.

In conjunction with our labours in the Etsin-gol region
to be described in the next chapter these surveys were in-
tended to complete the mapping of a well-defined portion
of north-western Kansu. This, inasmuch as it sends all its
waters into an undrained basin, may well be claimed in
respect of its general physical conditions as belonging to
Central Asia rather than to China. Previous experience had
prepared me for the reluctance of the local Chinese to ven-

about securing transport. But a fortunate chance brought
just then an old Chinese friend to the military command of
Kan-chou in the person of worthy General Tsai, whose
kindness I well remembered from my visit to Su-chou in
1907. His opportune help enabled us to set out for the
mountains by the first week of July.

The route followed during the first marches acquainted
