magic might hold an island in the sky.... Whee-e-e-e! what a black cloud!"

It grew suddenly dark, for they were rushing through a thick cloud that rolled around them in billows. Trot felt little drops of moisture striking her face and knew her clothing was getting damp and soggy.

"It's a rain cloud," she said to Button-Bright, "and it seems like an awful big one, 'cause it takes so long for us to pass through it."

The umbrella never hesitated a moment. It made a path through the length of the heavy black cloud at last and carried its passengers into a misty, billowy bank of white, which seemed as soft and fleecy as a lady's veil. When this broke away they caught sight of a majestic rainbow spanning the heavens, its gorgeous colors glinting brightly in the sun, its arch perfect and unbroken from end to end. But it was only a glimpse they had, for quickly they dove into another bank of clouds and the rainbow disappeared.
