"Pass?" inquired the sergeant, with friendly interest. "Yes," nodded Hal. Tip Branders was sitting in a chair, a dark scowl on his face. "Orderly, take Branders to the surgeon, now," continued the sergeant, and Tip disappeared. Then the sergeant knocked at the door of the lieutenant's office and entered after receiving the officer's permission. He came out in a moment, holding the door open. "Overton and Terry, the lieutenant will see you now." Hal and Noll entered, handing their papers back to Lieutenant Shackleton, who glanced briefly at the surgeon's reports. "I don't see much difficulty about your enlisting," smiled the officer. "I congratulate you both." "We're delighted, sir," said Noll simply. "Now, Overton, I can let you sign, provisionally, to-day but I can't accept your friend, Terry, until to-morrow, when he will have reached the proper age for enlisting. This may seem like a trivial thing to you, but Terry is just one day short of the age, and the regulations provide that an officer who knowingly enlists a recruit below the proper age is to be dismissed from the service. Now, if you prefer, Overton, you can delay enlisting until to-morrow, so as to enter on the same date with your friend." "I'd prefer that, sir," admitted Hal. "You are both in earnest about enlisting?" "Indeed we are, sir," breathed Noll fervently. "I believe you," nodded the officer. "Now, have you money enough for a hotel bed and meals until to-morrow forenoon?" "Yes, sir." "Then be here at nine o'clock to-morrow morning, sharp, and I'll sign you both on the rolls of the Army. Now, furnish me with home references, and, especially, the name of your last employer. These will be investigated by telegraph. Also, are you acquainted with the chief of police in your home city?" Hal and Noll answered these questions. Then, having nothing pressing on his hands for the moment, Lieutenant Shackleton offered the boys much sound and wholesome advice as to the way to conduct themselves in the Army. He laid especial stress upon truthfulness, which is the keystone of the service. He warned them against bad habits of all kinds, and told them to pick their friends with care, both in and out of the service. "In particular," continued the lieutenant, "I want to warn you against contracting the 'guard-house habit.' That is what we call it when a soldier gets in the habit of committing petty breaches of discipline such as will land him in the guard-house for a term of confinement for twenty-four hours or more. The 'guard-house habit' has spoiled hundreds of men, who, but for that first confinement, would have made admirable soldiers. The enlisted man with the 'guard-house habit' is as useless and hopeless as the tramp or the petty thief in civil life."
