brazen sky above. A cry broke from his lips.

"Why, what under the sun does it mean?" exclaimed Andy, who had also

"An aeroplane!" he burst forth in thrilling tones; "and the sillies down
there think it's just a frightfully big bird about to carry them

"It's--it's a biplane, Frank!" gurgled Andy.

"Yes, and one you've set eyes on before, too, old fellow. It belongs

"Puss Carberry!" burst from Andy's quivering lips, as he continued to
stare, as if almost unable to believe his own eyes.
