We watched them approach us.

They dashed against the rocks, swirled in the crevices, rose like scarfs on the wind, fell back in drops and sprays, and with one long, sweeping libration, gathered their green waters together and retreated.

When one wave left the sand, its currents immediately joined, and sought lower levels.

The sea-weed moved its slimy branches; the water bubbled between the pebbles, oozed through the cracks of the rocks and formed a thousand rivulets and fountains.

The drenched sand absorbed it all, and soon its yellow tint grew white again through the drying action of the sun.
As soon as we could, we jumped over the rocks and continued on our way.
Soon, however, they increased in numbers, their weird groups being crowded together, piled up and overturned on one another.
