After two more quarries the inhabited part of Inquanok seemed to end, and the road narrowed to a steeply rising yak-path among forbidding black cliffs. Always on the right towered the gaunt and distant peaks, and as Carter climbed farther and farther into this untraversed realm he found it grew darker and colder. Soon he perceived that there were no prints of feet or hooves on the black path beneath, and realised that he was indeed come into strange and deserted ways of elder time. Once in a while a raven would croak far overhead, and now and then a flapping behind some vast rock would make him think uncomfortably of the rumoured Shantak-bird. But in the main he was alone with his shaggy steed, and it troubled him to observe that this excellent yak became more and more reluctant to advance, and more and more disposed to snort affrightedly at any small noise along the route.
