"Then will you swim ahead and see what it is that my eyes show me on the water?"

"Oh, aye!"

With l.u.s.ty strokes the Dane swam around him, and then ahead.

"A little more to the left!" called Dave.

Then Captain Kennor believed that he saw it, too, and headed straight for the object. Getting nearer he sent back a real cheer.

"What is it?" Darrin called.

"A spar!"

"Any size?"

"Large enough us to hold all up! Swim dis vay! Alone, can I hardly push it to you."

Neither Dave nor the Englishman needed urging. They swam, still bearing the woman between them. The sight of the Dane ahead of them holding to the spar with one arm, and holding up the other hand, heartened them wonderfully.

Soon all three had gained the spar, and Captain Kennor, drawing a cord from his pocket, soon succeeded in lashing the Englishwoman so securely to the spar that she could not slip away and perish.

"Now, you will remember what I said about not giving up," Dave reminded his companions.

"Why, yes, I am buoyed up, and perhaps you men can manage to hold on, also," admitted the woman. "Yet we must freeze to death."

"We will still dare to hope," Darrin replied, calmly.

"You are a splendid inspiration, Mr. Darrin!" declared the Englishman, heartily. "I wish I could believe that you are a true prophet, as well."

"Oh, well," spoke Dave, with a lightness that was deceptive, "I've really been in several worse sc.r.a.pes than the present one."

But to himself he added:

"May I be forgiven for uttering what seems to me to be a possibly helpful lie!"

Though they were now safely afloat for some time to come, their situation rapidly became worse, owing to the increasing cold. Especially was this noticeable in the case of the Englishwoman.

From time to time her eyes closed. When spoken to she had to exert considerable effort to shake off her languor before she could reply. She became still more drowsy; evidently she was on the verge of freezing to death. From speaking kindly her husband dropped into sharp tones for the sole purpose of keeping her awake. Presently he was forced to resort to light blows in order to bully her into wakefulness. Once she fell soundly asleep she would not again awake.

As for Captain Kennor, he held on almost dumbly. He seldom spoke, his eyes mournfully regarding the woman whose battle for life was slowly being lost.

"This is awful!" cried the Englishman, hoa.r.s.ely, after another effort to rouse his wife from slumber.

"For all of us," Darrin admitted, "though there is still hope."

"Where?" inquired Captain Kennor.

"I do not know," Dave confessed. "Yes, I do, too, though! Look yonder!

No, in that direction!"

At first the others could not make it out. Captain Kennor was the first to see what Dave had found. It was only a low, dark cloud on the horizon, and it looked as though smaller clouds detached themselves and sailed away on the low-hanging sky.

"I see it, too!" cried the Englishman, at last. "But what is it?"

"A ship," Dave answered. "To be more exact, it looks like a destroyer, and it looks too as though it might pa.s.s within a quarter of a mile of us."

"Look, my dear--look!" the Englishman urged his wife, shaking her in his eagerness to have her realize the thread of hope that dangled before their eyes. "A ship coming! We are to be saved."

Her eyes opened at last; the woman struggled bravely to show interest in the sight that half-cheered the others, but she could not. She was too far gone, and her eyes closed again.

"Keep your wife awake, sir, if you have to begin to pull her hair from her head!!" It was a command. "See how near that craft is getting. Jove, sir! I believe it is one of our own Yankee ships!"

"But they will not come close enough to see us," objected Captain Kennor, with the practiced eyes of the veteran seaman. "They are not using their searchlight, and we have no way of signalling to them."

Without speaking Darrin tried a desperate hope. In one of his hands something gleamed out into the night.

"What is it?" demanded the Dane. "Himmel! Der flashlight! Vere or ven did you by dat come?"

"I found it in the locker of our sleeping cabin, and hid it in my clothes," Dave answered, as he again tested the light. "I did not want to speak of it unless there should come some hope to us. This light was evidently left by some German who had used that cabin. It's waterproof, too. When I found it I had a hope that it might come in handy before I got through with this adventure. And now!"

Waiting only a minute or two longer, Dave, clinging to the spar with one arm, held the other hand as high aloft as he could.

"Help!" he signalled by flashes in the Morse code. "Help!"

"It is such a tiny glow, to carry so far!" sighed the Englishman.

"Maybe id vill seen be," said Captain Kennor.

Dave continued to signal until, to his great joy, there came an answering signal from a blinker light which asked:

"Who are you?"

"Four castaways, clinging to a spar. Help before we freeze!" Dave flashed back, desperately.

"If only the commander of that boat does not suspect us of being a German submarine springing a trap!" cried the Englishwoman.

A searchlight flashed up, then its broad beam stretched across the waters as the operator tried to pick up the floating ones.

Dave threw the flash into a continuous light while the searchlight beam continued groping. Then, in a blessed instant, the beam struck almost blindingly across the spar and the four human beings held up by it.

"Now, they've spotted us," Dave cried, exultingly. "They won't run away and leave us without a look-in."

Holding the spar with the searchlight beam, the destroyer changed its course, bearing down rapidly upon them. Then it stopped and a motor launch was lowered from davits.

With a burst of speed the launch came alongside the spar. Busy hands were outstretched. The Englishwoman was the first to be taken aboard, after a few quick slashes had freed her from the binding cord.

[Ill.u.s.tration: "Help!"]

"Why, here's Lieutenant Commander Darrin!" exclaimed a voice. Dave, almost too weak to speak, was hustled into the boat, then the other two men were taken over.
