"The best of friends must part, as the hook said to the eye!" sang out
Tom, merrily.

"I believe you are anxious to leave us!" returned Nellie, teasingly.

"Sure thing!" he retorted, promptly. "I planned to get away an hour
before I came." And then she playfully boxed his ear, at which he
chased her around the biplane and gave her a hearty smack just below
her own pretty ear.

"Tom Rover!" she gasped. But, somehow, she looked pleased,
nevertheless.

"A11 in the family!" sang out the fun-loving Rover, coolly. "As the
lady said when she kissed her cow."

"Who is going to run the Dartaway back?" questioned Sam. "I think it's
my turn at the wheel."

"It's rather dark, Sam," answered Dick. "But you can try it-- if you
want to."

"All right-- I think I can see as much as you or Tom," responded the
youngest Rover. "If I get off the course, and you find it out, let me
know."

Darkness was settling down when the boys finally bid the girls
good-bye and flew away. "Beware of old Crabtree!" sang out Dick.

"We'll watch out!" answered Nellie.
