She saw him slink into a crevice and take off the suit, then, as he moved toward the river ravine, she stole up after him.

Suddenly she stopped stark still, surprised, and stared.

The man had actually gone up to the very waterfall. He had pressed what looked like a lever and the water over the falls seemed to stop. Then he walked directly through into a cave.

In the greatest wonder, Elaine crept along toward the falls. Inside the cave Del Mar's emissary started to climb a ladder to an inner cave. As he reached the top, he glanced out and saw Elaine by the entrance. With an oath he jumped into the inner entrance. His hand reached eagerly for a lever in the rocks and as he found and held it, he peered out carefully.

Elaine cautiously came from behind a rock where she had hidden herself and seeing no one apparently watching, now, advanced until she stood directly under the trickle of water which had once been the falls. She gazed into the cave, curiously uncertain whether she dared to go in alone or not.

The emissary jerked fiercely at the lever as he saw Elaine.

Above the falls a dam had been built and by a system of levers the gates could be operated so that the water could be thrown over the falls or diverted away, at will. As the man pressed the lever, the flood gates worked quickly.

Elaine stood gazing eagerly into the blackness of the cave. Just then a great volume of water from above crashed down on her, with almost crushing weight.

How she lived through it she never knew. But, fortunately, she had not gone quite far enough to get the full force of the water. Still, the terrific flood easily overcame her.

She was swept, screaming, down the stream.
