ied on shore.
I'll go with you, if you want."

"Will you, old man? I'll be a thousand times obliged!"

So the pair went off in search of the sick-bay, as the hospital part of
a battleship is called. The surgeon was not in his office adjoining, but
the hospital steward called him over one of the ship telephones,
informing him that a midshipman was suffering with an ulcerated tooth.

Dr. Mackenzie came at once, turned on a reflector light, and gazed into
Midshipman Pennington's mouth.

"Have you tried to treat this tooth yourself, in any way?" queried the
ship's surgeon.

"Yes, sir; I was so crazy with the pain, while in Annapolis, that I am
afraid I did something that will get me into trouble," replied
Pennington, with a quiver in his voice.

"What was that?" asked Dr. Mackenzie, glancing at him sharply. "Did you
try the aid of liquor?"

"Worse, I'm afraid, sir."

"Worse?"

Pennington told of his experience with the opium pipe.

"That's no good whatever for a toothache, sir," growled Dr. Mackenzie.
"Besides, it's a serious breach of discipline. I shall have to report
you, Mr. Pennington."

"I expected it, sir," replied Pennington meekly.

"However, the report won't cure your toothache," continued Dr. Mackenzie
in a milder tone. "We'll attend to that first."

The surgeon busied himself with dissolving a drug in a small quantity of
water. This he took up in a hypodermic needle and injected into the
lower jaw.

"The ache ought to stop in ten minutes, sir," continued the surgeon,
turning to enter some memoranda in his record book.

After that the surgeon called up the ship's commander over the 'phone,
and made known Pennington's report.

"Mr. Pennington, Captain Scott directs that you report at his office
immediately," said the surgeon, as he turned away from the telephone.

"Very good, sir. Thank you, sir."

Both midshipmen saluted, then left the sick-bay.

"This is where you have to go up alone, I guess," hinted Midshipman
Hallam.

"I'm afraid so," sighed Pennington.

"However, I'll be on the quarter-deck, and, if I'm wanted, you can send
there for me."

"Thank you, old man. You're worth a brigade of Darrins--confound the
greasing meddler!"

"Darrin acted according to his best lights on the subject of duty,"
remonstrated Mr. Hallam mildly.

"His best lights--bah!" snarled Pennington. "I'll take this all out of
him before I'm through with him!"

Pennington reported to the battleship's comm
