ceeded in breaking out.

The cabin was lighted, in day time, by side ports and a barred transom
overhead. The ports were too small to permit of a man forcing his way
through. Even though they broke the glass overhead, the prisoners in
the cabin would still have iron bars to overcome. Tom Halstead, with
his club, could hinder any work at that point.

In the meantime, the "Restless," once out of the cove, was bounding
over the waves like a thing of life. Though the water had been hard to
swim through, it did not present a rough sea for a fifty-five foot
power boat.

In less than three minutes Engineer Joe Dawson was sounding his auto
whistle like mad as he neared the dock at Lonely Island.

Just as the boat glided in, under decreased headway, to the dock the
bungalow door was seen to open. Powell Seaton, shot-gun in hand,
appeared on the porch. He watched, not knowing whether friend or foe
commanded the "Restless." Mr. Seaton, himself, was made to stand out
brightly in the middle of the searchlight ray that Joe turned upon
him, yet he could not see who was behind that light.

Running the boat in, bow-on, Joe leaped ashore with the hawser. Making
fast only at the bow, he next raced up the board walk, shouting the
news to Mr. Seaton. The latter, with a hail of delight, darted toward
the dock, arriving barely behind Dawson.

Down in the cabin the din of the men trying to escape had redoubled.
Powell Seaton tramped hurriedly aft, while Tom and Joe fell in behind
him with heavy tread, to give the rascals below an idea that numerous
reinforcements had arrived.

Bang! Pausing before the hatch Mr. Seaton raised the shot-gun to his
shoulder, discharging a single shell. Hastily slipping one into the
magazine of the weapon to replace the fired one, Seaton shouted
sternly:

"Stop your nonsense down there! If you get out it will be only to run
into the muzzles of fire-arms. You fellows are fairly caught!"

There was a startled silence, followed by indistinct mutterings. Not
even Anson Dalton, it appeared, cared to brave what looked like too
certain death.

Tom held a whispered consultation with his employer, then stepped over
to young Butts.

"Hank, we're going to leave you on shore. Mr. Seaton will come along
with the gun. Keep your eyes open--until you see us again! Don't be
caught napping. Remember, you and Dr. Cosgrove have the whole
protection of that helpless man, Clodis, _in_ your hands."

Hank Butts made a wry
