"Yes; I feel the need of fresh air."

"Shove off, then!"

Dave went out quietly, Dan gazing curiously after his friend until the
door had closed behind him.

"Poor chap," muttered Dan. "I reckon he has need enough of something to
stop that restless feeling. The class meets to-night!"

Jetson, after some fifteen minutes of aimless wandering, felt himself
attracted to the gymnasium. Going inside, he went to his locker, where,
with feverish energy, he changed to gym costume.

For a few minutes the sulky one performed on the flying rings. He was an
adept at this work, and something in the rapid motion soothed his
troubled mind.

Tiring of the rings at last, Jetson stood with folded arms, looking about
him, until his eyes lighted with interest on the trapezes. One was up
higher than the rest. Drawn toward this one, Jetson took hold of the
climbing rope and drew himself up, hand over hand. Seating himself on the
bar, he sat looking about at the few other midshipmen who were exercising
at that hour.

"There comes that Darrin fellow," thought Jetson, with a sudden burst of
rage. "Wonder if he's going to work this afternoon? If he does, I'll put
it all over him, even if I break my neck in the trying."

Back and forth swung Jetson, getting up speed on the trapeze. Then,
suddenly, he threw his head downward, hanging on by his knees. An
intentional slip, and he hung fully downward his ankles holding at the
ends of the crossbar.

Folding his arms, Jetson again began to swing as he hung head downward.
Among the midshipmen there were not so very many who were skillful at
this form of exercise. Jetson was, and he was secretly proud of it.

"This will put the fellow Darrin to the bad if he came in with any notion
of showing off," thought the sulky one exultantly.

Now the other midshipmen turned to leave the gym. In a moment more the
only two left were Darrin and the man on the trapeze. In addition to the
midshipmen there were two gym. attendants at some little distance.

"Who's doing that fine work?" wondered Dave, stepping closer. "Why, it's
Jetson! Well, he has one accomplishment that I really envy him!"

Midshipman Jetson was now going through some rapid evolutions, first
hanging head downward, and then, after developing speed, raising himself
and turning over the crossbar. It was really work of which any athlete
might have been proud.

"Say, Jim," muttered one attendant to the other, "that middie has me
nervo
