He sprang down into the vestibule with an ax in his hand. He had already closed down his helmet. He closed the door and flooded the vestibule.
CHAPTER IV.
IN THE ATLANTIC VALLEY.
It was but a moment’s work for Frank to spring out on deck. Then he reached the sands below.
Swinging the ax aloft, he rushed to Von Bulow’s assistance.
He was not a moment too soon.
Captain Bell had already attacked the monster. But Frank’s arrival saved the day.
The young inventor swung the ax over his head and made a slashing blow at the monster’s head.
It struck the enormous hawk-like beak and slashed off part of it.
Quick as thought Frank repeated the blow.
