"I guess that will do for to-night," said Mr. Dunn when it came nine o'clock. "I had most of the stuff checked up before you came aboard, or there'd have been more to do. However, we'll manage to keep you busy in the morning."

"I wonder if I'll ever get a chance to learn to be a pilot?" said Nat, for the purser seemed so friendly that he ventured to speak to him of that pet ambition.

"I shouldn't wonder. We're not very busy once we get loaded up, and often when sailing between ports a long distance apart there is little to do for days at a time. If you want to learn navigation, and Mr.

Weatherby will teach you, I don't see why you can't do it."

"I hope I can."

"Come on, and I'll show you where you'll bunk," went on Mr. Dunn. "You want to turn out lively at six bells in the morning."

"That's seven o'clock," observed Nat.

"Right you are, my hearty. I see you know a little something about a ship. That's good. Oh, I guess you'll get along all right."

It seemed to Nat that he had not been asleep at all when six strokes on a bell, given in the way that sailors ring the time, with short, double blows, awoke him. He dressed hurriedly, had his breakfast with the others of the crew, and then did what he could to help the purser, who had to check up some boxes that arrived at the last minute, just before the ship sailed.

A little later, amid what seemed a confusion of orders, the _Jessie Drew_ moved away down the river, and Nat was taking his first voyage on Lake Michigan as a hand on a ship--a position he had long desired to fill, but which hitherto had seemed beyond his wildest dreams.

"How do you like it?" asked Mr. Weatherby, a little later, as he pa.s.sed the boy on his way to the pilot-house.

"Fine."

"I'm glad of it. Attend strictly to business, and you'll get along.

I'll keep you in mind, and whenever I get a chance I'll take you into the pilot-house, and begin to instruct you in the method of steering a ship."

"I'll be ever so much obliged to you if you will."

"Why, that's nothing, after what you did for me," replied Mr.

Weatherby, with a kind smile at Nat.

As sailing on large vessels was not much of a novelty to Nat, except of late years, since his father's death, he did not linger long on deck, watching the various sights as the freighter plowed her way out on Lake Michigan. He went to the purser's office, to see if there was anything that needed to be done. He had temporarily forgotten about the mate's threat to have him discharged.

As Nat drew near the place, he heard voices in dispute, and, when he entered, he was surprised to see the first mate, Mr. b.u.mstead, standing at the purser's desk, shaking his fist in the air.

"I tell you those boxes are not aboard!" exclaimed the mate.

"And I say they are," replied the purser firmly. "They are down on my list as being taken on this morning, and--er--what's his name--that new boy--Nat--Nat Morton checked them off. You can see for yourself."

"Oh, he checked 'em off, did he?" asked the mate, in altered tones.

"Now I begin to see where the trouble is. We'll ask him----?"

"Here he is now," interrupted Mr. Dunn, as Nat entered. "Did you check up these boxes?" he asked, and he handed a part of the cargo list to Nat.

"Yes, sir. They were the last things that came aboard this morning."

"I told you so!" exclaimed Mr. Dunn, turning to the mate.

"Wait a minute," went on that officer. "He says he checked 'em off, but I don't believe he did. If he did, where are they? They can't have fallen overboard, and I didn't eat 'em, I'm sure of that."

"I checked those boxes off as you called them to me, Mr. b.u.mstead,"

replied Nat. "You stood near the forward cargo hold, and the boxes were stowed away there. I was careful in putting them down on my list."

"Yes! Too careful, I guess!" exclaimed the mate angrily. "You've got down ten more boxes than came aboard. That's a nice mess to make of it! But I knew how it would be if the captain took a greenhorn aboard!

Why didn't he get some one who knew how to check a cargo?"

"I know how to check a cargo," replied Nat quietly.

"I say you don't! There are ten boxes missing, and you've got to find them, that's all there is about it!"

"Everything down on my list came aboard," insisted Nat.

"Well, those ten boxes didn't, and I know it. You made a mistake, that's what you did, or else you let the boxes fall overboard, and you're afraid to admit it."

"No boxes fell overboard when I was checking up, Mr. b.u.mstead."

"Well, where are those ten missing ones then?"

"I don't know."

"Of course you don't. And no one else does. You made a mistake, that's all, and it's going to be a bad one. It puts me to a lot of work. I'll have to check over all my lists to make up for your blunder."

"I made no blunder."

"I say you did, and I'm going to report you to Captain Marshall. I'm not going to work with a greenhorn, who don't know enough to check up a simple list. I'll report you, that's what I'll do, and we'll see how long you'll have a berth on this ship!"

Angrily muttering to himself, the mate started for the captain's cabin, while poor Nat, much distressed over the trouble into which he had gotten, stood dejectedly in the purser's office.

CHAPTER VI

AN UNEXPECTED DISCOVERY

"Don't let him worry you," said Mr. Dunn consolingly. "He's a surly fellow, and he's always interfering in my department."

"But the captain may discharge me," replied Nat. "Still, I am sure those boxes came aboard. I counted them carefully and I don't believe I would be ten out of the way."

"Of course not. Probably the mate stowed them in some other place and he's forgotten all about it. They'll turn up."

"I hope so, for I would not like to make a mistake the first day out."

At that moment a deckhand came up to where Nat stood talking to the purser.

"Captain wants to see you," he said to the boy.

"Don't get excited now," advised Mr. Dunn. "Here, take our checking list with you and tell the captain exactly how it happened. If you are sure the boxes came aboard say so--and stick to it."
