“Eh?  What’s that?  What’s the matter?” began Tom, and then he suddenly sat up.  “Oh, my head!” he exclaimed, putting his hands to his aching temples.

“And that queer smell!” added Ned, who was also awake now.

“Bless my talcum powder!” cried Mr. Damon.  “I have a splitting headache.”

“Hum!  Chloroform, if I’m any judge!” called Mr. Nestor from his berth.

“Chloroform!” cried Tom, staggering to his feet.  “I wonder” He did not finish his sentence, but made his way to the room where his camera was kept.  “It’s gone!” he cried.  “We have been chloroformed in the night, and some one has taken my Wizard Camera.”

CHAPTER XX — AFTER THE ENGLISHMEN

“The camera gone!” gasped Ned.

“Did they chloroform us?” exclaimed Mr. Damon.  “Bless my—­” but for one of the few times in his life, he did not know what to bless.

“Get all the fresh air you can,” hastily advised Mr. Nestor.  “Koku, open all the doors and windows,” for, though it was hot during the day in the jungle, the nights were cool, and the airship was generally closed up.  With the inrush of the fresh air every one soon felt better.

“Is anything else gone?” asked Ned, as he followed Tom into the camera room.

“Yes, several rolls of unexposed films.  Oh, if only they haven’t got too much of a start!  I’ll get it away from them!” declared Tom with energy.

“From who?  Who took it?” asked Ned.

“Those Englishmen, of course!  Who else?  I believe they are in the pay of Turbot and Eckert.  Their taking pictures was only a bluff!  They got on my trail and stuck to it.  The delays we had, gave them a chance to catch up to us.  They came over to the airship, to pretend to borrow films, just to get a look at the place, and size it up, so they could chloroform us, and get the camera.”

“I believe you’re right,” declared Mr. Nestor.  “We must get after those scoundrels as quickly as possible!”

“Bless my shoulder braces!” cried Mr. Damon.  “How do you imagine they worked that trick on us?”

“Easily enough,” was Mr. Nestor’s opinion.  “We were all dead tired last night, and slept like tops.  They watched their chance, sneaked up, and got in.  After that it was no hard matter to chloroform each one of us in turn, and they had the ship to themselves.  They looked around, found the camera, and made off with it.”

“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.”
