“There will be no flood,” interrupted Mr. Parker impatiently.

“I’d be happy to leave this ark if only I could believe that,” sighed Noah. “I’m getting older, and it’s a great burden to care for so many animals. But I must not shirk my duty because I am tired.”

Penny knew that the old man could not be influenced by mere words. Glancing at the sky, she saw that although rain still fell, the sun had straggled through the clouds. Above the trees arched a beautiful rainbow.

“Noah!” she cried, directing his attention to it. “Don’t you remember the Bible quotation: ‘And I do set my bow in the cloud and it shall be for a token of a covenant between me and the earth.’”

“‘And the waters shall no more become a flood to destroy all flesh,’” Noah whispered, his fascinated gaze upon the rainbow.

“There, you have your sign, your token,” Mr. Parker said briskly.

“Yes, yes,” whispered the old man. “This is the hour for which I long have waited! Behold the rainbow which rolleth back the scroll of destiny! Never again will the flood come. Never again will destruction envelop the earth and all its creatures.”

“How about it Noah?” Mr. Parker asked impatiently. “If I make all arrangements will you leave the ark?”

The old man did not hesitate. “Yes, I will go,” he said. “My mission here is finished. I am content.”

Penny and her father did not annoy the old man with material details, but slipped quietly away from the ark. Glancing back, they saw that Noah still stood at the railing, his face turned raptly toward the fading rainbow. As the last trace of color disappeared from the sky, he bowed his head in worshipful reverence. A moment he stood thus, and then, turning, walked with dignity into the ark.
