CHAPTER II

YAWNS PROVE DISASTROUS

"Yah-h-h hum." Stacy Brown yawned loudly. "Yah-hum," breathed
Walter Perkins, half rousing himself from his nap.

"Ho-ho-hum," added the deep bass voice of Professor Zepplin.

"Yah--see here, stop that!" commanded Ned Rector, suddenly raising
himself to a sitting posture. "You've done nothing but stretch your
mouth in yawns ever since we reached Montana. See, you've waked up
the whole camp."

"Ho-hum," said Chunky.

"Say, what ails you?" demanded Tad, putting down by supreme force of
will, his own inclination to yawn.

"I--I guess--yah--it must be the--the mountain air. Yah-hum," yawned
the fat boy.

Pink-eye coughed off among the cedars.

"What means all this disturbance, young gentlemen?" demanded the
Professor.
