And now they came to the first hollow. On the right, where the hills opened out, was a wall of surf, whose crest threatened at any moment to topple over. More than one wave must have broken through already, which had left smaller and larger pools in the lowest parts of the ground; evidently not a moment was to be lost. But the Count saw that the passage might be ventured, which was fortunate, as in any case it must be tried.

"Follow me boldly, Carla!" he cried, as he again rode forward.

Carla answered not a syllable.

"It is all over between us," said the Count to himself; "she will never forgive me as long as she lives."

They rode on quickly, and had already reached the middle of the hollow, when the Count saw to his horror that the wall of surf, which had stood in the opening of the dunes, was in movement and seemed to be advancing towards them. For one moment he thought it was a delusion of his excited imagination, but only for a moment.

"On! for heaven's sake, on!" he cried, urging his exhausted horse to its utmost speed with whip and spur. He did not look round, he dared not look behind him; he knew from the fearful roar that the wave had flung itself far inland--behind him!

The panting horse staggered up the slope--saved!

He had no need to pull his horse up; it stopped of itself. Carla stopped by his side. How had she got through? He could not tell, and took care not to ask.

And now he looked back.

For a hundred yards at least of the hollow they had crossed, a single stream now carried its dark waters foaming and roaring far inland. The Count saw it with a shudder; there could hardly be a question that the same wave must have broken through above also, on the other side of the Pölitz's farm, and then in all probability the waters would have united behind the farm. If this were the case, only two places of refuge remained--the farm itself, or the lofty dune--called the White Dune--between the two hollows. The dune stood higher, but was farther off, and it was doubtful whether they could reach it as lower fields lay between it and the farm; besides, what would become of them up there?
