"That's what I will!" cried Tom. "If they get my camera away from me again, it will be my own fault."

The voyage to Colon was not specially interesting. They ran into a terrific storm, about half way over, and Tom took some pictures from the steamer's bridge, the captain allowing him to do so, but warning him to be careful.

"I'll take Koku up there with me," said the young inventor, "and if a wave tries to wash me overboard he'll grab me."

And it was a good thing that he took this precaution, for, while a wave did not get as high as the bridge, one big, green roller smashed over the bow of the vessel, staggering her so that Tom was tossed against the rail. He would have been seriously hurt, and his camera might have been broken, but for the quickness of the giant.

Koku caught his master, camera and all, in a mighty arm, and with the other clung to a stanchion, holding Tom in safety until the ship was on a level keel once more.

"Thanks, Koku!" gasped Tom. "You always seem to be around when I need you." The giant grinned happily.

The storm blew out in a few days, and, from then on, there was pleasant sailing. When Tom's airship had been reassembled at Colon, it created quite a sensation among the small army of canal workers, and, for their benefit, our hero gave several flying exhibitions.

He then took some of the engineers on a little trip, and in turn, they did him the favor of letting him get moving pictures of parts of the work not usually seen.

"And now for the volcano!" cried Tom one morning, when having shipped to Mr. Period the canal pictures, the Flyer was sent aloft, and her nose pointed toward Arequipa. "We've got quite a run before us."

"How long?" asked Ned.
