Oh, Mr.Rover, is anything wrong ?" "I don't know--I hope not.

But I think we had better go after them at once.

Good day." And Dick fairly ran back to where Tom and Sam rested near the biplane.
"Start her up, quick!" he said to his brothers, in a low voice.
"Something is wrong! We've got to get after the girls right away!" "What is it ?" demanded Tom, leaping to his feet, while Sam did the same.
"I'll tell you when we are on the way.

Quick, start the propellers! I'll take the wheel," and Dick sprang into the seat.
In another moment the engine had been started, and with a rush and a whizz the _Dartaway_ left the campus.

Dick made a turn, then headed in the direction of the road through the woods.
