Tom tried desperately to shift the wheel and, at the same time to elevate the airship to pass over the monster of the deep. But they were now so close that it seemed impossible. With the motors shut off the sound of the whale’s blowing could be heard and each moment the vast bulk became plainer. If the airship hit that mountain of flesh she would be instantly wrecked!

CHAPTER XXIV
THE LAST TRICK

“Start the engine! Give me some speed!” Tom yelled desperately. “I’ve got to zoom!”

He meant, by this, a sudden and sharp lifting of the airship over the whale, as a birdman often zooms to avoid crashing into trees or some obstruction.

Luckily, Peltok was on duty in the engine compartment. He had shut off power but a short time before, and the cylinders were still hot. In a second the machinist switched on the spark, hoping to start the motors on compression as can sometimes be done. To his delight it happened this time.

With a roar the powerful engines started up, whirring the propellers and giving the craft enough momentum for Tom to lift her over the whale’s back.

But so little room was there to spare that afterward, observers in near-by boats declared that the spouting of the whale wet the lower portion of the Monarch.

Tom could well believe this, for when the big creature, alarmed by the near approach of the air craft, raised its flukes and slammed them down on the surface of the sea, preparatory to sounding, the water was washed in a big wave over the rudders of the Air Monarch tearing loose some of the stays and guy wires of the elevating surfaces.

It was a narrow escape, and Tom realized this as, a little farther on, he brought his craft safely to the calm surface of the bay while behind him the waves were ruffled by the sinking of the whale that was soon lost to sight.

“If this keeps us,” remarked Ned whimsically, as he sat on a locker, “I’ll be a nervous wreck after this race. It’s just one bit of excitement and narrow squeak after another.”
