us half a show."

"That's just the trouble," grumbled Hal Hastings, breaking into the talk, at last. "Confound it, why don't the people of this country run their government more than they do? Four-fifths of the inventors who get up great things that would put the United States on top, and keep us there, have to go abroad to find a market for their inventions! If I could invent a cannon to-day that would give all the power on earth to the nation owning it, would the American Government buy it from me? No, sir! I'd have to sell the cannon to England, Germany or Japan—or else starve while Congress was talking of doing something about it in the next session. Mr. Farnum, you have the finest, and the only real submarine torpedo boat. Yet, if you want to go on building and selling these craft, you'll have to dispose of most of them abroad."

"I hope not," responded the shipbuilder, solemnly.

Having said his say, Hal subsided. He was likely not to speak again for an hour. As a class, engineers, having to listen much to noisy machinery, are themselves silent.

It was well along in the afternoon, a little past the middle of October.
For our three young friends, Jack, Hal and Eph, things were dull just
at the present moment. They were drawing their salaries from the
Pollard company, yet of late there had been little for them to do.

Yet the three submarine boys knew that big things were in the air. David Pollard was away, presumably on important business. Jacob Farnum was not much given to speaking of plans until he had put them through to the finish. Some big deal was at present "on" with the Government. That much the submarine boys knew by intuition. They felt, therefore, that, at any moment, they were likely to be called into action—to be called upon for big things.

As Jack and Hal sat in the office, silent, while Jacob Farnum turned to his desk to scan one of the papers lying there, the door opened. A boy burst in, waving a yellow envelope.

"Operator said to hustle this wire to you," shouted the boy, panting a bit. "Said it might be big news for Farnum. So I ran all the way."

Jacob Farnum took the yellow envelope, opening it and glancing hastily through the contents.

"It is pretty good news," assented the shipbuilder, a smile wreathing his face. "This is for you, messenger."

"This" proved to be a folded dollar bill. The messenger took the money eagerly, then demanded, more respectfully:

"Any answer, sir?"

"Not at this moment, thank you," replied Mr. Farnum. "That is all; you may go, boy."

Plainly the boy who had brought the telegram was disappointed over not getting some inkling of the secret. All Dunhaven, in fact, was wildly agog over any news that affected the Farnum yard. For, though the torpedo boat building industry was now known under the Pollard name, after the inventor of these boats, the yard itself still went under the Farnum name that young Farnum had inherited from his father.

While Jacob Farnum is reading the despatch carefully, for a better understanding, let us speak for a moment of Captain Jack Benson and his youthful comrades and chums.

Readers of the first volume in this series, "The Submarine Boys on Duty," remember how Jack Benson and Hal Hastings strayed into the little seaport town of Dunhaven one hot summer day, and how they learned that it was here that the then unknown but much-talked about Pollard submarine was being built. Both Jack and Hal had been well trained in machine shops; they had spent much time aboard salt water power craft, and so felt a wild desire to work at the Farnum yard, and to make a study of submarine craft in general.

How they succeeded in getting their start in the Farnum yard, every reader of the preceding volumes knows; how, too, Eph Somers, a native of Dunhaven, managed to "cheek" his way aboard the craft after she had been launched, and how he had always since managed to remain there.

Our same older readers will remember the thrilling experiences of this boyish trio during the early trials of the new submarine torpedo boat, both above and below the surface. These readers will remember, also, for instance, the great prank played by the boys on the watch officer of one of the stateliest battleships of the Navy.

Readers of the second volume, "The Submarine Boys' Trial Trip," will recall, among other things, the desperate efforts made by. George Melville, the capitalist, aided by the latter's disagreeable son, Don, to acquire stealthy control of the submarine building company, and their efforts to oust Jack, Hal and Eph from their much-prized employment. These readers will remember how Jack and his comrades spoiled the Melville plans, and how Captain Jack and his friends handled the "Pollard" so splendidly, in the presence of a board of Navy officers, that the United States Government was induced to buy that first submarine craft.

After that sale, each of the three boys received, in addition to his regular pay, a bank account of a thousand dollars and ten shares of stock in the new company. Moreover, Messrs. Farnum and Pollard had felt wholly justified in promising these talented, daring, hustling submarine boys an assured and successful future.

Jacob Farnum at last looked up from the final reading of the telegram in his hands. Captain Jack Benson's gaze was fixed on his employer's face. Hal Hastings was looking out of a window, with almost a bored look in his eyes.

"You young men wanted action," announced Mr. Farnum, quietly. "I think you'll get it."

"Soon!" questioned Jack, eagerly.

"Immediately, or a minute or two later," laughed the shipbuilder.

"I'm ready," declared Captain Jack, rising.

"It'll take you a little time to hear about it all and digest it, so you may as well be seated again," declared Farnum.

Hal, too, wandered back to his chair.

"You've been wondering how much longer the Government would leave the
'Pollard' here," went on Mr. Farnum. "I am informed that the gunboat
'Hudson' is on her way here, to take over the 'Pollard.'"

"What are the Navy folks going to do!" demanded Captain Jack, all but wrathfully. "Do they propose to tow that splendid little craft away!"

"Hardly that, I imagine," replied Farnum. "It's the custom of the United States Navy, you know, to send a gunboat along with every two or three submarines. They call the larger craft the 'parent boat'. The parent boat looks out for any submarine craft that may become disabled."

"The cheek of it," vented Jack, disgustedly. "Why, sir, I'd volunteer to take the 'Pollard,' unassisted, around the world, if she could carry fuel enough for such a trip."

"But the Navy hasn't been accustomed to such capable submarine boats as ours, you know," replied Mr. Farnum. "Hence the parent boat."

"Parent boat!" interjected Hal Hastings, with his quiet smile. "You might call it the 'Dad' boat, so to speak."

Mr. Farnum laughed, then continued:

"A naval crew will take possession of the 'Pollard,' and the craft will proceed, under the care of the Dad boat"—with a side glance of amusement at Hal—"to the United States Naval Academy at Annapolis."

"Annapolis—where they train the naval cadets, the midshipmen, into
United States Naval officers? Oh, how I'd like to go there!" breathed
Captain Jack Benson, eagerly.

"As a cadet in the Navy, do you mean!" asked Mr. Farnum.
