The Nieuport had shot above the strata of clouds.

Even though his nerves were still tingling, his pulse throbbing violently, the combat pilot could not repress a gasp of admiration as he gazed out over the immense expanse of billowy forms that stretched in every direction in a vast circle against the soft blue field of sky.

It was still early, the sun had not risen high, and its rays, falling upon the clouds, tinted them with the most delicate of rosy hues.

“I almost seem out of the world,” murmured Don, a trifle awesomely.

“And how perfectly safe it looks I—just as though one could float about on the clouds and be in no danger of taking a header to the earth. But where am I in this curious world above? And, more important than all, where are the other planes? I’d be in a nice position, shouldn’t I, if some of Captain Richtofen’s Red Squadron should happen to come along! What shall I do?”
