"Let her go!" cried Tom. "I'll do the rest of my moving picture work, around volcanoes and earthquakes, from up in the air!"

The Flyer shot upward, and scarcely a moment too soon, for, an instant after she left the ground, the stream of hot, burning and bubbling lava rolled beneath her, and those on board could feel the heat of it ascending.

"Say, I'm glad we got out of that when we did," gasped Ned, as he looked down. "You're all right, Koku."

"That no trouble," replied the giant with a cheerful grin. "Me carry four fellows like you," and he stretched out his big arms. Tom had at once set his camera to working again, taking view after view.

It was a terrifying but magnificent sight that our friends beheld, for the earth was trembling and heaving. Great fissures opened in many places. Into some of them streams of lava poured, for now the volcano had opened in several places, and from each crack the melted rocks belched out. The crater, however, was not sending into the air such volumes of smoke and ashes as before, as most of the tremendous energy had passed, or was being used to spout out the lava.

The earthquake was confined to the region right about the volcano, or there might have been a great loss of life in the city. As it was, the damage done was comparatively slight.

Tom continued to take views, some showing the earth as it was twisted and torn, and other different aspects of the crater. Then, as suddenly as the earthquake had begun, it subsided, and the volcano was less active.

"My! I'm glad to see that!" exclaimed Mr. Damon. "I've had about enough of horrors!"

"And I have too," added Tom. "I'm on my last roll of film, and I can't take many more pictures. But I guess I have all Mr. Period needs, and we'll start for home, as soon as I finish the next roll. But I'm going to save that for a night view. That will be a novelty."

The volcano became active again after dark, and presented a magnificent though terrifying aspect. As the airship hovered above it, Tom got some of his best pictures, and then, as the last bit of film slipped along back of the lens, the airship was headed north.
