This ugly monster straddled a long pole with its four bowed legs, the front end of which was attached to a U shaped collar that circled its scaly neck, and the rear end of which was fastened to a long chain of creaking, bumping carts, fastened together by hooks and rings. Each of these carts traveled on two large rollers in lieu of wheels, and contained many metal cylinders which jolted and banged together as the vehicle lumbered along. Walking beside the cart on each side was a long row of Lunites clad in sandals and coarse, loose fitting tunics that reached to the knees. The long black hair of these workmen was twisted up in a pointed, pagoda-like effect on top of the head. Each man carried a two handled metal urn, a short tube pointed at one end like a quill, and a small mallet. Behind the first dragon came two others, similarly harnessed and attended, and Ted, noticing that the last dragon snatched from time to time at the shoots of the luminous plants which grew by the roadside, munching each phosphorescent mouthful with apparent relish, saw the reason these creatures appeared to breathe fire. It was some time later that he learned this was a crew of sap gatherers, returning with a supply of cylinders filled with the luminous fluid with which the Lunite chemists made the yellow, light-emitting liquid which, suspended in transparent containers, lighted their underground cities. When the cavalcade had passed out of sight down the road the girl motioned him to rise, and together they resumed their flight. They passed many cross-lanes in the luminous forest, unmolested. Then the one on which they were traveling came to an end. The cultivated area now gave way to an immense tangle of luminous and non-luminous plants of various hues and shades—a tremendous hodge podge of winding creepers, low fungi of every conceivable shape, and tall trunks, jointed, smooth, and spiny—some topped like mushrooms, spears, stars or globes, others with long waving fronds like palms or ferns. Most of the non-luminous plants were white, although some were gray or black. Here and there among the common phosphorescent types of luminous plants were scattered groups and individuals which gave off red, green, pink, violet or yellow light. Some of them emitted two or three shades of one color, or even several colors of light. The whole scene was a vast, weird, fairyland of color and shade—at once, beautiful and forbidding. Into this tangle the girl plunged without the slightest hesitation. Ted followed, a pistol degravitor in his hand ready for instant action. As they progressed further and further into this subterranean wilderness the fauna of the place became more and more in evidence, indicating to Ted that, if one might judge from the conduct of the wild things, they were gradually receding from the haunts of man.
