sciousness descended on him....

The air was hot and damp and the slight breeze which fanned his cheek
was of little solace. Allerdyce turned his head from side to side; a
quiver stirred the heavy frame of his body, and awareness came in a
rush to him as he opened his eyes. He sat erect and looked about him.

A figure lay sprawled on the ground some ten feet away. It was that of
a man and one glance showed Allerdyce that the man was Ed Finster and
that he was alive, though not yet conscious. Allerdyce rose to his
feet and grunted at the effort. It seemed as if every bone and muscle
creaked and groaned in protest. Awe and amazement made his brows lift
and his eyes widen as he looked about. The two men had fallen among
some ferns in a shallow glade bound about by dense jungle growth.
Allerdyce caught a glimpse of hills in the near distance. Then he saw
Finster stir and he stepped to the other's side.

"Wha-what happened?" Finster asked while he turned his head from one
side to the other.

"I don't know exactly," Allerdyce replied in a low voice. "But I'm
going to make a guess, fantastic as it may sound. I think we fell or
were sucked into a space fault. From the looks of this jungle and from
the feel of the atmosphere, I'll bet we've landed in a time long
before the dawn of men such as we know...."

And as though in corroboration there came to their ears a low,
grunting sound. Instantly Finster leaped to his feet and jumped the
several feet to the side of the other. The sharp movement brought
another coughing grunt, this time from the opposite side. And as they
watched, a huge striped shape stepped into the open from the depths of
the thick jungle growth. It was fully ten feet long and high as their
shoulders, and the head of it was that of a tiger but such as they had
never seen, for twin tusks, a foot long protruded down the length of
the jowls....

"A saber tooth!" Allerdyce whispered hoarsely.

Ed Finster could only stare in open-mouthed horror at the thing. His
muscled jaws began to quiver as the tiger began a sinuous advance
toward them, and then, as the animal suddenly crouched in preparation
for its leap, Finster screamed.

But the tiger never moved from his crouch. As if by magic a half dozen
spears pierced its sides and two found a resting place in the tiger's
throat. Then the silence was broken by the hoarse shouts of human
voices, and a dozen men leaped into
