Hsüan-
tsang's
crossing of
Su-lo Ho.
'In the third watch they came to the river, and sighted the Yü-mên barrier from a distance.
At 10 li above the point where the barrier stood, the river banks were not much more than
a chang (10 feet) apart.'¹² Here a crossing was effected by a rough footway which the young
barbarian improvised with cut tree-branches, etc. After resting by the water's edge and having
discharged the young 'barbarian', who was unwilling to venture further, the pilgrim bravely set out
alone on the track leading to the first watch-tower. We shall follow him on this venture in a sub-
sequent chapter, and show that there is good reason for believing that his track could not have lain
far away from the present caravan route connecting An-hsi with Hāmī.¹²ᵃ
Local data
in Hsüan-
tsang's Life.
From this short account and the local information previously given to Hsüan-tsang we gather
the following topographical data. Starting from the town of Kua-chou, the route towards Hāmī
first led north for 50 li to the river Hu-lu, where the watch-station of Yü-mên kuan was placed.
From this point the route towards Hāmī turned to the north-west and passed into the desert.
Hsüan-tsang, having to avoid the watch-station where his unauthorized move beyond the border
would have been stopped, set out from Kua-chou at night and reached the river in the third watch
at a point some 10 li above the Yü-mên barrier, and there managed to effect a crossing unperceived.
Thence he picked up the track leading to the nearest of the watch-towers, at which, as we are told
in the Life, he arrived after covering 80 li.¹⁴
Topo-
graphical
data verified.
It is easy to see that these indications are in full accord with the topographical facts as the
map shows them. By the river Hu-lu no other but the Su-lo Ho can be meant.¹⁵ From the
ruined town of Kua-chou-ch'êng, which in view of its central position and surviving local tradition
may safely be assumed to mark the approximate site of the Kua-chou of T'ang times,¹⁶ it is 8 miles
almost exactly due north in a straight line to the point where the road to Hāmī crosses
the Su-lo Ho. If we assume that its course lay in Hsüan-tsang's days about two miles further to
the north, where Rai Rām Singh's reconnaissance survey marks an old river-bed,¹⁷ the agreement
in distance with the 50 li of the Life becomes still closer; for the equation of 5 li to the mile is the
one which my experience of Hsüan-tsang's distance reckonings on Central-Asian ground has proved
to be the generally correct average.¹⁸ That the road to Hāmī, after leaving the Su-lo Ho, leads
steadily in a north-west direction is a fact which the map clearly demonstrates. Finally it is note-
worthy that the 80 li which Hsüan-tsang is said to have covered from the river crossing to the
first watch-tower agree remarkably well with the 16 miles or so which Map No. 81 shows between
