Again the trio pressed on through hurricane and moonlight, still farther into the wilderness. It seemed to the men as though they must long since have lost their way and there was no escape from this desert where one ridge rose beyond another in perpetual, horrible monotony, but Danira walked on undisturbed without once hesitating. At last she stopped and turned.

"We have reached our goal," she said, pointing down into the depths below. "There is the Vila spring."

Gerald paused to take breath, and his eyes wandered in the direction indicated. The ground suddenly sloped sheer down and he saw at his feet a chasm, close by a huge, projecting rock. It was a strange formation of stone, towering upward in broad massive outlines, curiously jagged at the top, the peak inclined so far forward that it looked as if it must break off and fall. Beyond this gateway the ravine appeared to widen, for they saw the moonlight glitter on some rippling water.

"Must we go down there?" George asked his lieutenant, doubtfully, in a low tone. "The rock hangs over like one of our bunches of ripe grapes at home. I believe it will drop on our heads as soon as we come near it. Everything in Krivoscia is spiteful, even the stones."

"The rock will not fall," replied Danira, who had heard the words, "it has hung so for centuries, and no storm has ever shaken it. Follow us."

She had already descended and Gerald followed without hesitation. They both passed the rock gateway and George could not help joining them. He cast one more suspicious glance upward; for he had become accustomed to regard everything in this country as a personal foe, but the rocky peak, by way of exception, showed no disposition to molest him, and remained quietly in its threatening attitude.

The distance was not very great. In a few minutes both reached the bottom of the cliffs and stood in a ravine which widened rapidly above, but was accessible only through the rock gateway. Here too flowed the water they had seen above, one of the little streams which often burst suddenly out of the rocky soil of the Karst and in a short time as suddenly vanish again. Even here the water preserved its beneficent power, for fresh grass was growing around it, thin and scanty, it is true, but a sign of life amid this petrified nature, and there was life also in the clear waves which, with a low ripple and murmur, made a channel down the ravine.

Danira, with a sigh of relief, leaned against the cliff. The exhaustion of the rapid walk or excitement had made the girl tremble from head to foot, and she really seemed to need the support.

"We have reached the spot," she said, softly. "Here you are safe."

Gerald, who meantime had scanned the surroundings, shook his head doubtfully.
