a cry for aid and succour.

"Help! For love of God, save me!"

"White,--an American, too!" exploded Waldo, taking action as by
brilliant inspiration. "Hang over him, uncle, for I'm going--to
go fishing--for a man!"

Waldo was tugging at the grapnel and long drag-rope. Bruno was
quick to divine his intention, and lent a deft hand, while the
professor manipulated the helm so adroitly as to keep the
flying-machine hovering directly above yonder imperilled
stranger, leaning far over the hand-rail to shout downward:

"Have courage, sir, and stand ready to help yourself! We will
rescue you if it lies within the possibilities of--we WILL save
you!"

"You bet we just will, and right--like this," spluttered Waldo,
as he cast the grapnel over the rail and swiftly lowered it by
the rope. "Play you're a fish, stranger, and when you bite, hang
on like grim death to a--steady, now!"

Fortunately nothing occurred to mar the programme so hastily
arranged, for the drift was drawing nearer the centre of the
whirl, and if once fairly caught by that, nothing human could
preserve the stranger from death.

"Make a jump and grab it, if you can't do better!" cried Waldo,
intensely excited now that the crisis was at hand.
