Dinner was eaten afloat, and after giving the professor a chance to look for the flying frog, but without success, preparations were made for the return.

“I told you we could make the trip easily in a day,” observed Jerry to his chums, as, toward the close of the afternoon, they were nearing Cresville.

“Yes, the Comet is doing herself proud,” declared Ned. “I hope we take a prize with her at Colton.”

“Sure we will,” insisted Bob, who was feeling very fine because of a good dinner.
