"We will not!" exclaimed Betty, above the noise. She shifted the wheel
to bring the boat head-on to the waves, and this made her ride on a
more even keel. Then, with a downpour, accompanied by terrific thunder
and vivid lightning, the storm broke. Betty bravely stood to her post,
the others offering to relieve her, but she would not give up the
wheel, and remained there until the little dock was reached. Then,
making snug their craft, they raced for the tent. It had stood up
well, for it was protected from the gale by big elm trees. Soon they
were in shelter.

And then, almost as suddenly as it had come up, the storm passed. The
clouds seemed to melt away, and the sun came out, the shower passing
to the East.

Grace, who had gone out on the end of the dock, called to the others.

"Oh, come on and see it!"

"What-- the ghost?" inquired Mollie.

"No, but the most beautiful rainbow I ever saw-- a double one!"

They came beside her, and Grace pointed to where, arching the heavens,
were two bows of many colors, one low down, vivid and perfect, the
other above it-- a fainter reflection. As the sun came out from behind
the clouds the colors grew brighter.

"How lovely!" murmured Amy, clasping her hands.
