"Good morning, sir."

Still that "sir" to the citizen. The sergeant would drop it, as far as these two boys were concerned, if they entered the service and became his subordinates.

It seemed to Hal and Noll as if they could not get over the ground fast enough until they reached that doorway where the orderly stood. The orderly directed them how to reach the office upstairs, and both boys, after thanking him, proceeded rapidly to higher regions.

They soon found themselves before the door. It stood ajar. Inside sat a sergeant at a flat-top desk. He, too, was of the cavalry. There were also two privates in the room.

Doffing their hats Hal and Noll entered the room. Overton led the way straight to the sergeant's desk.

"Good morning, Sergeant. We have come to see whether we can enlist."

"How old were you on your last birthday?" inquired the sergeant, eyeing Hal keenly.

"Eighteen, Sergeant."

"And you?" turning to Noll.

"Seventeen," Noll replied.
