vil, glistening,
pointing coldly down to where they were struggling towards the shore.
Phil Holmes felt his strength ooze out. He heard Professor Guinness
gasp:

"A water-snake!"

* * * * *

Its head was reared above the surface, gliding down on them silently,
leaving a wedge of long, sluggish ripples behind. When thirty feet
away the glistening head dipped under, and a great half-circle of
leg-thick body arched out. It was like an oily stream of curved cable;
then it ended in a pointed tail--and the creature was entirely under
water....

With desperate strength Phil hauled the girl to the bank and, standing
in several feet of water, pushed her up. Then he whirled and yanked
old Guinness past him up into the hands of his daughter. With them
safe, and Sue reaching out her hand for him, he began to scramble up
himself.

But he was too late. There was a swish in the water behind him, and
toothless, hard-gummed jaws clamped tight over one leg and drew him
back and under. And with the touch of the creature's mouth a stiff
shock jolted him; his body went numb; his arms flopped limply down. He
was paralyzed.

Sue Guinness cried out. Her father stared helplessly at the spot where
his young partner had disappeared with so little commotion.

"It was an eel," he muttered dully. "Some kind of electric eel...."

Phil dimly realized the same thing. A moment later his face broke the
surface, but he could not cry out; he could not move his little
finger. Only his involuntary muscles kept working--his heart and his
lungs. He found he could control his breathing a little.... And then
he was wondering why he was remaining motionless on the surface.
Gradually he came to understand.

He had not felt it, but the eel had let go its hold on his leg, and
had disappeared. But only for a moment. Suddenly, from somewhere near,
its gleaming body writhed crazily, and a terrific twist of its tail
hit Phil a glancing blow on the chest. He was swept under, and the
water around him became a maelstrom. When next he bobbed to the
tumultuous surface, he managed to get a much-needed breath of
air--and in the swirling currents glimpsed the long, snake-like head
of the eel go shooting by, with thin trickles of stuff that looked
like white jelly clinging to it.

That explained what was happening. The eel had been challenged by the
ameboid monster, and they were fighting for possession of him--the
common prey.
