302 THROUGH RICHTHOFEN RANGE CH. LXXVII
supplies for men and animals had also to be inspected. Four donkeys were provided, in addition, to carry the pony-men's rations. In the midst of all this bustle I almost missed the farewell visit of the attentive Magistrate. The morning was delightfully cool, and as soon as the two miles of bare alluvial slope, with many traces of terraced fields now abandoned, had been crossed to the mouth of the valley, I found myself in refreshing verdure.
A picturesque tower guarded the entrance, and by its side a richly decorated temple, half in ruins, and a hamlet lay ensconced under big trees. A shop newly built by the roadside, and a gaily painted little shrine behind it, were evidently intended for the patronage of the miners who travel by this route to the gold-fields high up in the mountains.

At present only scraped on the surface, they may yet prove for Kan-su the promise of a great industrial future.
