"Now," he said, "I'll have to look over the ship."

Frank accompanied him on his tour of inspection. They found everything absolutely clean and ship-shape. The muzzles of the big guns were shining brightly beneath their coat of polish. After the inspection, Jack and Frank went below for a look at the ship's papers.

The Brigadier was a small destroyer, not more than 200 feet long. It had a complement of 250 men, officers and crew; carried two batteries of 9-inch guns in turrets forward and aft and was equipped with three 2-inch torpedo tubes. It was not one of the latest of British destroyers, but still it was modern in many respects.

"A good ship," said Jack, after a careful examination of the papers. "As to speed, we should get twenty-three knots on a pinch. Her fighting equipment is excellent, everything is spick and span, and I was impressed with the officers and crew. Yes, she is a good ship."

"And you're the boss of the whole ranch, Jack," said Frank. "Think of it.

Less than four years ago you knew nothing at all of naval tactics, and now you're in command of a British destroyer. By George! I wouldn't mind having your job myself."

Jack smiled.

"Never mind," he said. "You'll get yours some day. I've just been more fortunate, that's all. Besides, I knew something of navigation before you did, and while you have mastered it now, I had a long start."

"That's true enough," Frank admitted, "but at the same time you are considerably more fit for the job than I am. Another thing. I don't know that I would trade my berth here for a command of a ship."

Jack looked his surprise.

"Why?" he asked.

"Because it would separate us," was Frank's reply. "We've been together now since the war began, almost. I hope that we may see it through together."

"Here, too," declared the commander of the Brigadier, "but at the same time you should not let a matter of friendship stand between you and what may be your big opportunity."

"Oh, I'd probably take the job if it were offered me," said Frank. "I'm just hoping the offer will not be made; that's all."

The lads conversed for some moments longer. Then Frank looked at his watch.

"My watch," he said quietly. "I'll be going on deck."

"Right," said Jack. "Call me if anything happens."

"Yes, sir," said Frank, saluting his commander gravely.

Jack grinned.

"By Jove! It seems funny to have you talk like that to me," he said. "At the same time I suppose it must be done for the sake of discipline.

However, it is not necessary in private."

"Nevertheless," said Frank, "I had better stick to it or I'm liable to forget in public some time."

"Well, maybe you're right," said Jack.

Frank turned on his heel and went on deck, where he relieved Lieutenant Hetherton, who had been on watch.

"Nothing to report, sir," said Lieutenant Hetherton, saluting.

"Very well, sir," was Frank's reply, as he, too, saluted.

It was after midnight, and Frank's watch was nearing its end when the lookout on the port side called:

"Boat off the port bow, sir."

Frank advanced to the rail. A moment later there was a hail from the water.

"What ship is that?'

"His Majesty's Ship Brigadier," Frank called back.

"I'm coming aboard you," said the voice from the darkness. "Lower a ladder."

Frank gave the necessary command. A few moments later a man attired in the uniform of a British captain came over the side. He approached Frank, who was barely visible in the darkness.

"Captain Templeton?" he asked.

"No, sir. I'm Lieutenant Chadwick. A moment, sir, and I'll call the captain."

"If you please," said the visitor.

Frank passed the word for the quartermaster, who arrived within a few moments.

"Call Captain Templeton," Frank directed.

Jack arrived on deck a few moments later and exchanged greetings with his visitor. The latter produced a packet of papers.

"From the admiralty," he said. "You will know what to do with them."

Jack took the papers and stowed them in his pocket.

"Yes, sir," he said.

"That is all, then," said the visitor. "I shall be going."

He stepped to the side of the vessel and disappeared.

"This means," said Jack, after the other had gone, "that we can sail any time now."

"Then why not at once?" asked Frank.

"You anticipated me," replied Jack. "Will you kindly pipe all hands on deck, Mr. Chadwick?"

Frank passed the word.

Sleepy men came tumbling from their bunks below. All became bustle and hurry aboard the Brigadier. Jack himself took the bridge. Frank stood beside him. Other officers took their places.

"Man the guns!" came Jack's order.

It was the lad's intention to overlook nothing that would protect the ship should it encounter an enemy submarine en route, and, as the lad knew, it was just as possible they would encounter one in the English Channel as elsewhere.
