-a shark!

Like a flash she turned and faced the monster. Something she had drawn
from her girdle shone palely in her hand. It was a knife of whetted
stone or bone.

Darting swiftly downward her feet spurned the yellow sand, and she shot
at her enemy with amazing speed. The long blade swept in an arc, ripped
the pale belly of the monster just as he turned to dart away.

A great cloud of blood dyed the water. The white figure of the girl shot
onward through the scarlet flood.

Blinded, she did not see that the jutting ribs of the ancient ship were
in her path. I seemed to see her crash, head on, into one of the
massive timbers, and I cried out involuntarily, and glanced down at the
girl in the water at my feet.

Her eyes were glowing. She knew that I had understood.

I flung the instrument from my head and dropped to the bottom of the
pool. I gripped both her shoulders, gently, to express my thanks and
friendship.

My heart was pounding. There was a strange fascination about this girl
from the depths of the sea, a subtle appeal that was answered from some
deep subterranean cavern of my being. I forgot, for the moment, who and

echo of a long-forgotten instinct.

I think I kissed her. I know her arms were about me, and that I pressed
her close, so that our faces almost met. Her great, weirdly blue eyes
seemed to bore into my brain. I could feel them throbbing there....

I forgot time and space. I saw
