dumb with wonder and delight.

It was not dark in this vast cave, yet the light seemed to come from
underneath the water, which all around them glowed with an exquisite
sapphire color. Where the little waves crept up the sides of the
rocks they shone like brilliant jewels, and every drop of spray
seemed a gem fit to deck a queen. Trot leaned her chin on her hands
and her elbows on her lap and gazed at this charming sight with real
enjoyment. Cap'n Bill drew in the oars and let the boat drift where
it would while he also sat silently admiring the scene.

Slowly the little craft crept farther and farther into the dim
interior of the vast cavern, while its two passengers feasted their
eyes on the beauties constantly revealed. Both the old seaman and
the little girl loved the ocean in all its various moods. To them it
was a constant companion and a genial comrade. If it stormed and
raved, they laughed with glee; if it rolled great breakers against
the shore, they clapped their hands joyfully; if it lay slumbering
at their feet, they petted and caressed it, but always they loved
it.

Here was the ocean yet. It had crept under the dome of overhanging
rock to reveal itself crowned with sapphires and dressed in azure
gown, revealing in this guise new and unexpected charms. "Good
morning, Mayre," said a sweet voice.

Trot gave a start and looked around her in wonder. Just beside her
in the water were little eddies--circles within circles--such as are
caused when anything sinks below the surface. "Did--did you hear
that, Cap'n Bill?" she whispered solemnly.
