a small bow and
a blunt arrow after this. Even. then I fear our eyes will be in
danger. Do you see what you did?"

One of Stacy's bullets had bored a hole through the crown of the
professor's sombrero. The other had plowed a neat furrow through
Professor Zepplin's grizzled whiskers, close to the chin.

"Ho, ho, ho! Haw, haw, haw!" roared the fat boy with head thrown back
as far as it would go without dislocating his neck.

CHAPTER XXI

A HOLE IN THE MOUNTAIN

The professor gave Stacy a shaking that the fat boy did not forget at
once, the others shouting their approval. The fat boy grinned after
his punishment.

"I'm a regular William Tell, eh?" he asked looking about. It was
still a good joke to him. Even the professor permitted a grim smile
to show itself at the base of his whiskers.

"You came near killing Professor Zepplin," answered the Ranger.

"That would have been too bad," replied Stacy almost anxiously. "I
shouldn't have had anybody to tease then. Do I try that shot again?"

"You do not!" was the firm reply from McKay.

"Come, come, boys, if you are going to shoot any more you'd better

You will turn and shoot at it when I give the word," said the captain.

The first shot Tad missed the hat by some three or four rods. How the
boys did shout and jeer at him!

"I did better than you. I trimmed the professor's whiskers," declared
Chunky.

Tad nodded to McKay that he was ready for another shot.

"Don't shoot this time until you see the hat. Shoot a little under
rather than over it. The natural tendency is always to overshoot,
whatever one is shooting at."

Bang!

The hat in the air jumped as if it had received a sudden blow as Tad
whirled and let go.

"You've graduated. Next!"

Rector missed five shots. Walter fanned the rim, then they called a
halt in the practice.

"Altogether I am well satisfied with your shooting,
