t was dusk when they roared in through the gate at the Rockland County Airport and pulled up at the hangar office. Van rushed in, shouting for Bill Petersen, and Bart followed. A slender, fair-haired youth in rumpled flying togs greeted them.

"Bill, my friend, Bart Madison," Van blurted without pausing for breath. "Listen, we've got to have a plane right away. Got one with a radio?"

"Yes, but what's all the rush? Where you going?"

"Albany. Right away. Make it snappy, will you?"

"Sure, but what's it all about?" Young Petersen was leading them to the field where a sleek mono-plane was in waiting as if they had ordered it. "Warm her up, Joe," he called to the mechanic.

"Listen, Bill—I never lied to you, did I?" Van asked, when they were seated in the plane's cabin.

"Not that I know of. But sometimes I've thought you were lying, until I saw with my own eyes the things you had told me about. What is it this time?"

"Death and destruction. Coming down out of the Ramapos. We've got to warn the country. Plants, Bill—squirmy red plants with long feelers that can twist around a man and devour him. Half animal, they are, and the feelers break loose and crawl by themselves. Multiplying like nothing you ever saw. Millions of them in an hour."

"What?" Petersen stared incredulously as his motor roared into life. Then he gave his attention to the business of taking off. He jerked the thumb of his free hand toward the radio.
