"Wait until I get in the purser's office," he mused as he puffed at his cigarette. "I'll soon learn all there is to know, and then I'll have my uncle see the captain and have me made purser. I don't like Mr. Dunn. When I get his job I'll take things easy, and have a couple of a.s.sistants to do the work. Maybe I'll let Nat be second a.s.sistant,"

he went on. "Won't I make him stand around, though!"

These thoughts were very pleasant to Sam Shaw. At heart he was a mean youth, and he was lazy and inefficient, faults to which his uncle was, unfortunately, blind. Mr. b.u.mstead thought Sam was a very fine boy.

In one of his trips about the deck, attending to his duties, Nat had to pa.s.s close to Sam. He saw the red-haired lad smoking a cigarette, and, knowing it was against the rules of the ship to smoke in that part of it where Sam was, he said:

"You'd better throw that overboard before the captain sees you."

"Throw what overboard?" asked Sam in surly tones.

"That cigarette. It's against the rules to smoke 'em here."

"What do I care?" retorted Sam. "My uncle is the mate."

"That won't make any difference if Captain Marshall sees you."

"I'm not afraid of him. My uncle owns part of the ship. He could be captain if he wanted to. I'll smoke wherever I please. Have one yourself?" he added in a burst of generosity, for since he had had his idea of becoming purser and having Nat for an a.s.sistant, Sam felt in a little more tolerant mood toward our hero.

"No, thanks, I don't smoke."

"Afraid of being sick, I s'pose."

"No, it isn't that."

"Afraid the captain will see you and punish you, then?"

"Well, that's part of it. I used to smoke when I was about the docks, but I found it didn't agree with me, so I gave it up. I like a cigarette, but I believe they're bad for one's health. Besides, if I did smoke, I wouldn't do it here. It's against the rules, I tell you, and you'd better stop."

"Well, I'm not going to, and you can go and tell Captain Marshall if you want to."

"I don't do things like that," replied Nat quietly, though he felt like punching Sam for his sneering tone. "But I'm advising you for your own good."

He turned away, and as he did so his coat, with an outside pocket showing conveniently open, was close to Sam's hand. Then a daring and mean scheme came into the mind of the red-haired youth.

"If I get into trouble, I'll make trouble for him, too," he thought, and with a quick motion he dropped into Nat's pocket a partly-filled box of cigarettes. "If he squeals on me I'll have something to tell on him," he continued.

Hardly had he done this than he was startled by an angry voice exclaiming:

"Throw that cigarette overboard! How dare you smoke on this deck?

Don't you know it's against the rules? Go below at once and I'll attend to your case!"

Sam started guiltily, and turned to behold Captain Marshall glaring at him and at the lighted cigarette which the youth still held between his fingers. Nat, who had pa.s.sed on only a few steps, turned likewise.

One look at the commander's face told him Captain Marshall was very angry indeed.

"I told you that you'd better stop," Nat whispered to Sam.

"Aw, dry up!" was the ungracious retort. "I guess I can look out for myself."

"Look here," went on the captain, striding up to Sam, "didn't you know it was against the rules to smoke up here? I don't like cigarettes in any part of the ship, least of all up on this deck. Didn't your uncle tell you about it?"

"No--no, sir," replied Sam, who, in spite of his bravado, was startled by the angry manner of the commander.

"And didn't any one tell you that it was forbidden here? Didn't you tell him?" he asked, turning to Nat. "You've been here long enough to know that rule."

"I did know it, sir," replied Nat respectfully, "and I told----"

"He didn't tell me!" burst out Sam quickly. "He didn't say anything about it. In fact, Captain Marshall, he asked me to smoke here. He gave me the cigarette!"

"What!" exclaimed Nat, astonished beyond measure. "I never----"

"Yes, you did!" went on Sam quickly. "You gave me a cigarette out of a box you had in your pocket, I--I thought it was all right to smoke when he gave it to me."

"Is this true?" demanded the captain sternly.

"No, sir!" exclaimed Nat. "I haven't any cigarettes, and if I had I wouldn't give him any. I haven't smoked in over a year."

"He says you have a box in your pocket now," continued Captain Marshall, remembering his suspicions about the fire in the hold.

"He's telling an untruth," replied Nat quietly. "I don't carry cigarettes about with me. You can----"

"Then what's this?" asked the commander suddenly, as he stepped toward Nat, and plunging his hand in the lad's pocket he pulled out the box of cigarettes. The captain had seen a suspicious-looking bulge, and had acted on what he considered his rights as a commander of a vessel in searching one of his crew.

"Why--why----" stammered Nat. "I didn't know----"

"That's the box my cigarette came out of," said Sam, truthfully enough.

"It isn't mine!" exclaimed Nat.

"Then what's it doing in your pocket?" inquired Captain Marshall.

"I don't know, unless Sam put it there," said Nat firmly.

"That's a likely story! I don't believe you."

"I never put it there," declared Sam stoutly. Telling an untruth meant nothing to him.

"Then some one else, who wants to injure me, did it," declared Nat. "I never use cigarettes--I haven't for over a year."

"This will be looked into," said the captain. "One of you lads is telling an untruth, and I propose to find out who. When I do I shall take action. Meanwhile I'll hold these cigarettes as evidence. Don't let me catch either of you smoking again aboard this ship. As for you," he added, turning to Nat, "you've been idle long enough. Get on with your work."

CHAPTER XII

THE INVESTIGATION

Nat hardly knew what to make of the strange turn of events. It had happened so suddenly that he had no time to prepare himself. He was positive Sam had dropped the cigarettes into his pocket, but to prove it was another matter. He knew the mate would take the side of his nephew, while Nat had no one to stand up for him.
