"Oh, we've no reason to think Truax isn't honest enough," contended Jack Benson. "He's certainly a fine workman. As to his being sulky, you know well enough that's a common fault among men who spend their lives listening to the noise of great engines. A man who can't make himself heard over the noise of a big engine hasn't much encouragement to talk.

Now, a man who can't find much chance to talk becomes sulky a good many times out of ten."

"We'll have trouble with that fellow, Truax, yet," muttered Eph.

"Oh, I hope not," Jack answered, then added, significantly:

"If he _does_ start any trouble he may find that he has been trifling with the wrong crowd!"

Very little more thought was given to the sulky one. The submarine boys and their companion, Williamson, enjoyed Sat.u.r.day and Sunday ash.o.r.e.

All of them might have felt disturbed, however, had they known of one thing that happened.

The naval machinists aboard the first submarine boat, the "Pollard," now owned by the United States Government, found something slightly out of order with the "Pollard's" engine that they did not know exactly how to remedy.

Sam Truax, hanging around the Basin that Sunday forenoon, was called upon.

He gladly responded to the call for help. For four hours he toiled along in the "Pollard's" engine room. Much of that time he spent there alone.

The job done, at last, Truax quietly received the thanks of the naval machinists and went ash.o.r.e again.

Yet, as he turned and walked toward the main gate of the grounds, there was a smile on Sam Truax's face that was little short of diabolical.

"Now, if I can only get the same chance at the 'Farnum's' engines!" he muttered, to himself. "If I can, I think Mr. Jack Benson will find himself out of favor with his company, for his company will be out of favor with the Navy Department at Washington!"

CHAPTER XIV: THE "POLLARD" GOES LAME

"The submarine boats when out in the Bay will keep abreast of the 'Hudson,' two hundred yards off on either beam. The speed will be fourteen knots when the signal is given for full speed. The general course, after leaving the mouth of the Bay will be East."

Such were the instructions called from the rail of the gunboat, through a megaphone, Monday forenoon.

On each of the submarine craft were sixteen cadet midshipmen, out for actual practice in handling a submarine in diving and in running under water. On board the gunboat were eighty more cadets. Thus a large cla.s.s of the young men were to receive instruction during the cruise, for the detachments aboard the submarines could be changed at the pleasure of Lieutenant Commander Mayhew, who was in charge of the cruise.

Captain Jack, his own hands on the conning tower wheel, ran the "Farnum"

out into the river, first of all. Then the "Pollard," under command of a naval officer, followed. Both backed water, then waited for the "Hudson"

to come out, for the gunboat was to lead the way until the Bay was reached. Then the formation ordered would be followed.

Though it was nearing the first of November, the day, near land, was ideally soft and balmy. As many of the midshipmen as could sought the platform deck of the "Farnum." Those, however, who belonged to the engineer division were obliged to spend the greater part of their time below.

By the time that the three craft were in the ordered formation, abreast, and well started down Chesapeake Bay, the parent vessel signaled that the designated cadets were to take charge of the handling of the submarine boats.

Jack Benson cheerfully relinquished the wheel to Cadet Midshipman Merriam, and stepped out on to the platform deck. At need, as in case of accident or misunderstanding of signals or orders, Benson was still in command.

While all ran smoothly, however, Mr. Merriam enjoyed command.

Hal, being likewise relieved in the engine room, came also out on deck.

"Where's Eph?" inquired the young commander of the "Farnum."

"In the engine room," smiled Hal. "He said I could leave, if I wanted, but that he'd be hanged if he'd let Truax out of his sight while I was away."

"Eph seems to have Truax on the brain," laughed Jack.

"Well, Truax _is_ a queer and surly one," Hal admitted. "This morning he gives one the impression of peeking over his shoulder all the time to see whether he's being watched."

"So Eph means to humor him by watching him, eh?" asked Jack.

Hal laughed quietly.

Some of the cadets who were familiar with the landmarks of Chesapeake Bay pointed out many of the localities and sights to the two submarine boys.

At last, however, Eph was obliged to call for Hal.

"You know, Hal, old fellow, I've got to look out for the feeding of a lot of boarders to-day," complained Eph, whimsically.

This task of Eph's took time, though it was not a hard one. The food for the cadets had been sent aboard. Eph had to make coffee and heat soup. For the rest, cold food had to do. The young men, on this trip, were required to wait on themselves.

Hal found Sam Truax sitting moodily in a corner of the engine room, though there was something about the fellow's appearance that suggested the watchfulness of a cat.

"Why don't you go on deck a while, Truax?" asked Hal, kindly.

"Don't want to," snapped the fellow, irritably. So Hal turned his back on the man.

"Doesn't that part need loosening up a bit, sir?" asked the cadet in charge of the engineer division.

"Yes," replied Hastings, after watching a moment; "it does."

"I'll do it, then," proposed Truax, roughly. He attempted to crowd his way past Hal, but the latter refused to be crowded, and stood his ground until the midshipman pa.s.sed him a wrench. Then Hastings loosened up the part.

"You might let me do a little something," growled Sam Truax, in a tone intentionally offensive.

"Don't forget, Truax, that I'm in command in this department," retorted Hal, in a quieter tone than usual, though with a direct, steady look that made Sam Truax turn white with repressed wrath.

"You won't let me forget it, will you?" snarled the fellow.

"No; for I don't want you to forget it, and least of all on this cruise,"

responded Hal Hastings.

"You don't give me any chance to-"

"Silence!" ordered Hal, taking a step toward him.

Sam Truax opened his mouth to make some retort, then wisely changed his mind, dropping back into his former seat.

The noon meal was served to all hands. By the time it was well over the mouth of the Bay was in sight, the broad Atlantic rolling in beyond.

The sea, when reached, proved to be almost smooth. It was ideal weather for such a cruise.
