“Oh! he’s going to drop something on us, Frank!” cried Andy, suddenly.

“Who is—Sandy?” demanded the other. “Give me a push as it leaves his hand!”

Andy did not understand, but he was in the habit of minding what Frank said; and three seconds later he brought his elbow sharply against the pilot’s side.

Sandy had let go above, allowing the bulky object to fall through space!

CHAPTER XXII.
WELL WON!

Instantly Frank closed the throttle, and shut off all power!

It was taking a big chance; but there was nothing else to be done. No matter what it was Sandy had let slip, expecting that it would fall upon the monoplane, to at least cause consternation, and in some way lessen the speed of the smaller craft, Frank did not mean that it should strike them, if he knew it.

Of course their speed instantly slackened; not much, perhaps, but just enough to allow of a miss in the calculations of the unscrupulous Sandy.

Some object whizzed past, just in advance of the now descending monoplane. Immediately it went by, Frank, under the belief that the danger was now over, once more carefully opened the throttle.

Joy! the faithful little Kinkaid answered to the call, and began to renew its former volleying. Once more they were going along swiftly, though a bit lower than when the sudden emergency had caused such prompt work on the part of the wide-awake pilot.
