Barney attacked the body of the serpent, trying to cut the huge coil in two.

The attack was a success.

Again Frank’s ax struck the serpent full in the neck, cutting a huge gash.

Then the maddened reptile made a savage blow at Frank.

It just missed him by a narrow margin and proved the end of the struggle.

Frank saw his opportunity, and gave the reptile a blow which almost severed its head from its body.

The monster’s huge coils went writhing and twisting into the depths of the cavern.

The struggle was over.

Frank and Barney, somewhat exhausted by the struggle, climbed aboard the Dart.

They were joyfully welcomed by the others, and mutual congratulations were exchanged over the success of the fight.
