The Submarine Boys on Duty Part 24

"Don't try it any longer. Get overboard, Miss Desmond, if there's yet time. In heaven's name do!" begged Jack, in a horrified tone. "I can stand going to the bottom if I don't have to drag you down with me.

Escape!"

"Not and leave a fellow human being here in your plight," retorted the girl quietly, though with sublime heroism.

"But you can't save me, anyway."

"Then I'll go down at my post, just as a man would," she retorted, throwing all her frantic strength into her task. How she blamed herself that her muscles were so weak!

"Please go! There may be time."

"I'm not thinking of that. Oh, for a man's strength!"

Jack's breath was bated. His dread for himself was forgotten now, as he watched the efforts of this splendid girl.

"We'll take the last plunge at any instant, now!" screamed Jack Benson.

"There may be time for _you_--"

"Then there'll be time for us both," came the undaunted answer. Grace Desmond did not turn her head as she spoke, but Jack, his intense gaze upon her, knew the light that was flas.h.i.+ng in her eyes at this moment.

A sound above told the submarine boy the worst. The water was gently rippling against the edges of the platform deck. That told him, all to plainly, how near the diving boat was to doing the work for which it had been built.

Could Jack have been close enough to see just why Grace was failing in her effort he might have told her better just what to try to do.

Now, he tried to explain, rapidly. The fault was not with her strength; there was an exact knack needed in the use of the wrench.

On sh.o.r.e, in the yard, Josh Owen crouched low in his place of concealment. He had failed to prevent Grace from starting in the rowboat because, until it was too late, he did not believe the plucky young woman had any such intention.

"It's too bad for the gal to go to the bottom, too," half sighed the raging one. "But she shouldn't meddle."

Hal came swinging along down the street, having left Eph Somers behind in the village. Through the yard came young Hastings, whistling. By instinct he turned to look at the boat, and what he saw made him gasp, then leap forward in the start of a sprint.

Straight down to the harbor's edge he raced. Then, seeing the rowboat adrift, Hal, after one more look at the sinking submarine, leaped into the water without stopping even to shed jacket or cap.

Splas.h.!.+ In the same instant that he sprang, Josh Owen jumped up.

"Come back here, or ye'll wish ye had!" raged the ex-foreman.

Hal Hastings heard, though he did not even take the trouble to answer, but struck out frenziedly, for his chum's calls for help now rang in his ears.

There was the sound of a discharge, a sharp split of fire from a weapon that Owen held in his hand. A bullet struck the water just before Hal's nose, das.h.i.+ng the spray back in his face.

"Come back here, I tell ye!" raged the ex-foreman.

"Josh Owen's voice!" throbbed Hastings, but he swam on with the strongest strokes of which he was master. Then a succession of shots rang out.

Hal Hastings was in the gravest danger he had ever been in.

CHAPTER XVI

THE LAST SECOND OF THE NICK OF TIME

Despite the whistle of lead, minding only the spray that dashed into his eyes, Hal Hastings swam on.

His one idea, at present, was to reach that submarine boat if it were within human power to do so ere the boat, now nearly all submerged, took the final plunge below the waves.

Grace Desmond did not quit her post, nor cease her heroic efforts to turn on the compressed air. Yet she added her shrill shrieks to Jack Benson's l.u.s.ty yells for help.

The sounds of the shots from the sh.o.r.e gave them a momentary hope that help of some sort was really on its way.

"It's the last second or two, if you mean to save us!" yelled Jack, at the top of his voice.

Bang! bang! Josh Owen fired two more shots from his dangerous automatic revolver as Hal caught at the rail of the boat.

"The last chance to save us!" repeated Jack.

"I know it," came, breathlessly, as the dripping Hal dropped down the manhole. He did not even wait to make use of the stairs.

By a fortunate impulse Grace Desmond fell back as young Hastings appeared.

Hal's right hand shot out, gripping the wrench. The "Pollard" gave a surge that all aboard believed to be her final one.

Yet Hal hung to his post, resolved to go down trying.

There was a hiss of compressed air. The "Pollard" didn't quite make the death plunge. Then she seemed to go, ever so little, toward a more level keel.

"I--believe--I've got her!" cried Hal Hastings.

A moment or two later he felt sure of it. He gave a cheer to ease his pent-up feelings, then suddenly gasped:

"Jack, do you know how much compressed air there is?"

"No," replied Benson, blankly.

"Heaven grant there's enough for what we must do," prayed Hal, aloud.

There were two shots over in the yard just now. The three young people heard the discharges, though they paid no heed to them at this critical instant.

Slowly the "Pollard" continued to regain evenness of keel.

Then Hastings, s.h.i.+fting the wrench to another part of the compressed air apparatus, opened the sea-valves of the amids.h.i.+ps water tanks to expel water.

Briefly, now, they knew that the "Pollard" had risen. Also, she was resting on an even keel. Hal, bedewed with cold perspiration, darted up the stairs to the conning tower. He looked out, and the first glance told him the "Pollard" was riding the water as she should.

"It's all right--now," he called down, with a strong effort at calmness.

"Jack, what on earth happened that you had to call for help!"

Then he caught sight of his chum, lashed to the stanchion. Hastings's mouth went wide agape with astonishment.
