And instantly he was obsessed with the flaming color of that man's unappeased passion. Red—red! The hovels were spattered with the red clay. The man, the skinny, wretched creature who begged for a moment of his gracious mercy at the gate, dripped in ruby filth. The mule sank and wallowed in vermilion mire.

Scrawny, undernourished children, naked, or in rags that afforded little more protection than nakedness, thrust their starved, red-smeared faces up at him, and gibed and howled.

And above all this arose the white majesty of his palace—the throne of the Gray Dragon!

Peter urged the mule up the scarlet alley to a clearing in which he found coolies by the thousands, trudging moodily from a central orifice that continued to disgorge more and more of them. The dreadful, reeking creatures blinked and gaped as if stupefied by the rosy light of the dying day.

Some carried lanterns of modern pattern; others bore picks and shovels and iron buckets, and they seemed to pass on interminably, to be engulfed in the lanes which ran in all directions from the clearing.

It was as though the earth were vomiting up the vilest of its creatures. And in the same light it was consuming others of equal vileness. Down into the red maws of the shaft an endless chain of men and women and children were descending.

Quite suddenly the light gave way, and Peter was aware that the night of the mountains was creeping out over the city, blotting out its disfigurements, replacing the hideous redness with a velvety black.

At the shaft's entrance a sharp spot of dazzling light sprang into being. It was an electric arc light! Somehow this apparition struck through the horror that saturated him, and he sighed as if his mind had relinquished a clinging nightmare.

Professionally now he gave this section of Len Yang another scrutiny. Thick cables sagged between stumpy poles like clusters of black snakes, all converging at the mine's entrance. His acute ears were registering a dull hum, indicating the imminence of high-geared machinery or of dynamos.

At the further side of the red shaft, now crusted with the night's shades, and garishly illuminated by the diamond whiteness of the frosty arc, he made out a deep, wide ditch, where flowed slowly a ruddy current, supplied from a short fat pipe.
