"We're coming," Wayne shouted, and returned the signal. It was at that instant that he felt something slam against the sole of his heavy metamagnetic boot. It was as though something had kicked him savagely on the sole of his right foot.
He winced sharply at the impact. Then, somewhat puzzled he looked down at the boot. He felt something move under the sand. He tried to step back, and almost tripped. It was as though his right foot were stuck firmly to the sand!
He pushed himself back, and with a tremendous heave managed to pull himself free. He braced his body against the cliff, lifted his foot, and looked at it.
Hanging from his boot sole was one of the ugliest monstrosities he had ever seen, unusually grotesque.
It was about the size and shape of a regulation football, and was covered with a wrinkled, reddish hide. At one end was a bright red gash of a mouth studded with greenish, gnashing teeth. From the other end of the creature's body protruded a long, needle-like projection which had imbedded itself in the metal sole of Wayne's boot.
"Good God! If I'd been wearing ordinary boots, that thing would have stuck clear into my foot!"
He hefted the weighted pick with one hand and swung, catching the monster with the point. It sank in and ripped through the creature, spilling red-orange blood over the sand. Shuddering a little, Wayne put his other foot on the dead thing and pulled his right boot free of the needle beak.
He started to say something, but he had a sudden premonition that made him look up in time. Sergeant Boggs put both hands against the Captain's shoulder and pushed.
"What the hell?" Wayne asked in surprise as he felt the shove. He almost fell to the sand, but he had had just enough warning to allow him to keep his balance. He put out a foot and staggered wildly.
