The sun had just come up over the great slope whereon leagues of primal brick foundations and worn walls and occasional cracked pillars and pedestals stretched down desolate to the shore of Yath, and Carter looked about for his tethered zebra. Great was his dismay to see that docile beast stretched prostrate beside the curious pillar to which it had been tied, and still greater was he vexed on finding that the steed was quite dead, with its blood all sucked away through a singular wound in its throat. His pack had been disturbed, and several shiny knick-knacks taken away, and all round on the dusty soil were great webbed footprints for which he could not in any way account. The legends and warnings of lava-gatherers occurred to him, and he thought of what had brushed his face in the night. Then he shouldered his pack and strode on toward Ngranek, though not without a shiver when he saw close to him as the highway passed through the ruins a great gaping arch low in the wall of an old temple, with steps leading down into darkness farther than he could peer.
