"Well, I'm going to get right after them!" cried Tom. "Ned, start the motor. I'll steer for a while."

"Hold on! Wait a minute," suggested Mr. Nestor. "I wouldn't go off in the ship just yet, Tom."

"Why not?"

"Because you don't know which way to go. We must find out which trail the Englishmen took. They have African porters with them, and those porters doubtless know some of the blacks around here. We must inquire of the natives which way the porters went, in carrying the goods of our rivals, for those Englishmen would not abandon camp without taking their baggage with them."

"That's so," admitted the young inventor. "That will be the best plan. Once I find which way they have gone I can easily overtake them in the airship. And when I find 'em—" Tom paused significantly.

"Me help you fix 'em!" cried Koku, clenching his big fist.

"They will probably figure it out that you will take after them," said Mr. Nestor, "but they may not count on you doing it in the Flyer, and so they may not try to hide. It isn't going to be an easy matter to pick a small party out of the jungle though, Tom."

"Well, I've done more difficult things in my airships," spoke our hero. "I'll fly low, and use the glass. I guess we can pick out their crowd of porters, though they won't have many. Oh, my camera! I hope they won't damage it."

"They won't," was Ned's opinion. "It's too valuable. They want it to take pictures with, themselves."

"Maybe. I hope they don't open it, and see how it's made. And I'm glad I thought to hide the picture films I've taken so far. They didn't get those away from us, only some of the blank ones," and Tom looked again in a secret closet, where he kept the battle-films, and the others, in the dark, to prevent them from being light-struck, by any possible chance.
