The RED DUST _By Murray Leinster_ _A Sequel to "The Mad Planet."_ [Transcriber's Note: This etext was produced from January 1927 Amazing Stories.

He had fallen upon the shining back of one of the huge, meat-eating beetles, and his spear had slid across the horny armor and then stuck fast, having pierced only the leathery tissue between the insect's head and thorax.] _You who have read "The Mad Planet" by Murray Leinster, will welcome the sequel to that story. The world, in a far distant future, is peopled with huge insects and titanic fungus growths. Life has been greatly altered, and tiny Man is now in the process of becoming acclimated to the change. We again meet our hero Burl, but this time a far greater danger menaces the human race. The huge insects are still in evidence, but the terror they inspire is as nothing compared to the deadly Red Dust. You will follow this remarkable story with breathless interest._ CHAPTER I Prey The sky grew gray and then almost white. The overhanging banks of clouds seemed to withdraw a little from the steaming earth. Haze that hung always among the mushroom forests and above the fungus hills grew more tenuous, and the slow and misty rain that dripped the whole night long ceased reluctantly. As far as the eye could see a mad world stretched out, a world of insensate cruelties and strange, fierce maternal solicitudes. The insects of the night--the great moths whose wings spread far and wide in the dimness, and the huge fireflies, four feet in length, whose beacons made the earth glow in their pale, weird light--the insects of the night had sought their hiding-places. Now the creatures of the day ventured forth. A great ant-hill towered a hundred feet in the air. Upon its gravel and boulder-strewn side a commotion became visible. The earth crumbled, and fell into an invisible opening, then a dark chasm appeared, and two slender, threadlike antennæ peered out. A warrior ant emerged, and stood for an instant in the daylight, looking all about for signs of danger to the ant-city. He was all of ten inches long, this ant, and his mandibles were fierce and strong. A second and third warrior came from the inside of the ant-hill, and ran with tiny clickings about the hillock, waving their antennæ restlessly, searching, ever searching for a menace to their city.
