Kim had all a plains-man's affection for the well-trodden track, not six feet wide, that snaked among the mountains; but the lama, being Tibetan, could not refrain from short cuts over spurs and the rims of gravel-strewn slopes. As he explained to his limping disciple, a man bred among mountains can prophesy the course of a mountain-road, and though low-lying clouds might be a hindrance to a short-cutting stranger, they made no earthly difference to a thoughtful man. Thus, after long hours of what would be reckoned very fair mountaineering in civilised countries, they would pant over a saddle-back, sidle past a few landslips, and drop through forest at an angle of forty-five on to the road again. Along their track lay the villages of the hill-folk--mud and earth huts, the timbers now and then rudely carved with an axe--clinging like swallows' nests against the steeps, huddled on tiny flats half-way down a three-thousand-foot glissade; jammed into a corner between cliffs that funnelled and focused every wandering blast; or, for the sake of summer pasture, cowering down on a neck that in winter would be ten feet deep in snow. And the people--the sallow, greasy, duffle-clad people, with short bare legs and faces almost Esquimaux--would flock out and adore. The Plains--kindly and gentle--had treated the lama as a holy man among holy men. But the Hills worshipped him as one in the confidence of all the devils. Theirs was an almost obliterated Buddhism, overlaid with a nature-worship fantastic as their own landscapes, elaborate as the terracing of their tiny fields; but they recognised the big hat, the clicking rosary, and the rare Chinese texts for great authority; and they respected the man under the hat. 'We saw thee come down over the black Breasts of Eua,' said a Betah who gave them cheese, sour milk, and stone-hard bread one evening. 'We do not use that often--except when calving cows stray in summer. There is a sudden wind among those stones that casts men down on the stillest day. But what should such folk care for the Devil of Eua!' Then did Kim, aching in every fibre, dizzy with looking down, footsore with cramping desperate toes into inadequate crannies, take joy in the day's march--such joy as a boy of St. Xavier's who had won the quarter-mile on the flat might take in the praises of his friends. The hills sweated the ghi and sugar suet off his bones; the dry air, taken sobbingly at the head of cruel passes, firmed and built out his upper ribs; and tilted levels put new hard muscles into calf and thigh.
