"Well, well! how are you, Giddings?  How are you, Robert?" cried Mr. Wrenn, sticking out his pudgy hand when he came up to the little group.

Mr. Giddings introduced John, Paul, and Tom, and then the publisher of the _Clarion_ continued with good-humored raillery: "I'm mighty glad to see you fellows here, for I began to think you would get scared and flunk us at the last moment. Was over on the hotel veranda when I saw a plane land here, and I guessed it might be you, and hurried right over.  Put your machine up yet?"
