"Ridiculous!" murmured William Philander.

"Absolute fact, Tubbs," responded Spud, earnestly. "Come with me, some day, and I'll show you where the pies made a dent in the street when the flying machine struck 'em." And then a general laugh went up, and the dudish student stepped back in the crowd, out of sight.

"All aboard!" sang out Dick, as he hopped into the driver's seat and took hold of the wheel. "Start her up, somebody!"

Sam and Tom got aboard and willing hands grasped the propellers and gave each a twist. Bang! bang! bang! went the explosions, and soon the propellers were revolving swiftly, and then with a swoop the Dartaway ran over the campus on its wheels and suddenly arose in the air. A cheer went up, and the students threw up their caps. Then Dick swung around in a quarter circle and headed directly for Plankville.

It was an ideal day for flying, not too hot or too cold, and with very little breeze, and that of the "steady" kind, not likely to develop "holes"—the one great terror of all airmen.

"Wish we had the girls along," remarked Sam, when they were well on the way.

"Not for this trip, Sam," answered Dick, grimly. "We have got our work cut out for us."

"Why, what do you mean?"

"If old Crabtree hasn't been caught yet me must see if we can't round him up."
