"You are sure you found the right place?"

"Is—is this not part of it?" Again the girl sought for something on the ledge. What she held out to him was a length of metal rod, twisted and broken at one end as if a giant hand had wrenched it loose from the installation.

Ross nodded dully. "Yes," his voice was harsh as if the words were pulled out of him against his will and against all hope—"that's part of a side bar. It—it must have been totally wrecked."

Yet, even though he held that broken length in his hands, Ross could not really believe the gate was gone. He swam out once more, heading for the reef where the dolphins joined him as guides. There was a second piece of broken tube, the scattered containers of supplies, that was all. The Terrans were wrecked in time as surely as those ships had been wrecked on the sea reef the night before!

Ross headed once again for the cave. Their immediate needs were of major importance now. The containers must be all gathered and taken into their hiding place, because upon their contents three human lives could depend.

He paused just at the entrance to adjust the net of containers he transported. And it was that slight chance which brought him knowledge of the intruder.

On the ledge Karara was heaping up the kelp of the nest. But to one side and on a level with the girl's head....

Ross dared not flash his torch, thus betraying his presence. Leaving the net hitched to the rock by its sling, he swam under water along the side of the cave by a route which should bring him out within striking distance of that hunched figure perching above to watch Karara's every move.
