by half-past five o'clock, won't you?"

"Without fail," Dick smiled back, "unless circumstances beyond
our control prevent us."

Good-byes were eagerly called, Dr. Bentley warmly expressing his
thanks to Reade and Hazelton for their assistance. Then, with
a warning honk, the big car started away.

Then all hands turned upon Dick. "Prescott, why on earth did
you let us in for a dinner and dance to-morrow night?" quivered
Greg.

"Look at us---the only outside clothes we have with us!" exploded
Danny Grin.

"We're frights!" chimed in Dave.

"We'll disgrace the girls," blurted Tom, "unless in the meantime
we can find some real tramps with whom to trade clothes."

"We'll feel ashamed enough to drop, when we get among civilized
folks," moaned Harry.

"This is a fine chance to prove or disprove Tom's theory that
a fellow ought to feel most at home in his old working clothes,"
chuckled Dick.

"Was that why you did it---accepted that dinner and dance invitation?"
gasped Dave.
