"Deviling" sentries is an old, old amusement at West Point. The plebe goes on duty, solemn and anxious, awed to silence and gravity by the sternness of his superiors. He is proud of his important office and thoroughly resolved to do his duty, come what may, and to die in the last ditch. He seizes his gun resolutely; feels of the bayonet point valiantly; puts on his sternest and most forbidding look; strides forth with a step that is bold and unwavering. And the yearlings "don't do a thing" to him.

What they did to Mark and his friends will be described later on.

CHAPTER VII.
MARK'S COUNTERPLOT.

Mark returned to the camp to find his six friends just returned from drill and enjoying a brief respite until the summons came for their next duty. He gathered them together in solemn conclave, and then in whisper imparted to them the information he had just received from the "angel."

The effects of Mark's announcement upon his friends varied considerably with each.

Indian was terrified beyond measure; the possibility of such tricks being tried upon him, too, made his fat eyes bulge. Texas, on the other hand, was wild with excitement and joy, and a little good-natured envy.

"Wow! Mark," he cried. "Why is it you always have all the fun? Them ole cadets always go fo' you; nobody else kin ever do anything. Ef them fellers don't git roun' to me some day I'm goin' off an' raise a rumpus some other way."

"What'll you do?" inquired Mark, laughing.

"I'll go off'n git on a roarin' ole spree!" vowed the other, solemnly. "An' I'll ride into this yere ole camp an' raise such a rumpus as it ain't ever seen afore. Jes' you watch me now! What you fellers a-laughin' at?"
