ss, but at the expense of straining the engines or
fuel or something. They're doing excellent work right now, so let's not
disturb them. It won't be long now."

The minutes seemed to drag like hours, however, to the boys. The glasses
were constantly used by Tom, who was perched on top of the pilot house,
sweeping the water for a trace of a sail.

"I see her," he shouted. "I mean Ship Ahoy. No, Sail Ho."

Directly the Fortuna overhauled the vessel they pursued.

"I want to speak to your captain," hailed Jack.

"Keep off, or I'll shoot," replied the mate at the rail.

"Bob, Bob White," came a whistle from the rigging.

CHAPTER XX

RESCUED AT SEA

"Bob, Bob White," replied Frank from the Fortuna. "Oh, there you are,
Charley. Thank God. Oh, come down and come aboard."

"Yes, he'll come aboard," vociferated the mate in a coarse voice. He was
a brutal looking fellow, to whom the boys instantly took a violent
dislike. "He'll stay where he is and so will you."

With these words he drew from the pocket of his trousers a revolver of
old style, but of aspect fully as vicious as its owner. It was of large
calibre, and from the way in which the mate handled it he was evidently

But Jack was not to be daunted so easily. Stretching the truth a bit,

shook the menacing revolver and shouted:

"You fellows keep off or I'll shoot. You can't steal my crew. I'm a
bucko mate, I am. You better sheer off."

"Drop that gun, you villain!" cried Charley Burnett, high up in the
schooner's rigging. At his words the mate turned.

Instantly a ringing voice from the Fortuna called out:

"Now I've got the drop on you! Let that gun go and tell the captain I
want to talk to him or I'll have to shoot."

Tom was perched on top of the Fortuna's pilot house with a rifle in his
hands, the muzzle pointed straight at the mate.

When the coward saw that he was indeed covered by a weapon in the hands
of a determined person, his grasp on his own means of o
