“There’s a pretty stiff breeze blowing, eh, fellows?” was his unexpected question.

“Mr. Ogden ’phoned from the hangar at Border City that Major Carroll has made an ascent in his dirigible.”
“He’s done that before,” exclaimed Dave, wondering at Bob’s expression. “Is anything the matter?”
“Mr. Ogden fears there is something wrong with the air-ship,” answered Bob.
