“Drop more!” cried Tom, sending the ship about in a circle, and hovering it over the middle of the press of savages.

More of the deadly tombs exploded.  The pygmies were running about wildly.  Tom, who was closely watching the rear of the cavalcade, suddenly called out: 

“Now’s our chance!  They’ve let their captives go, and are running into the jungle.  We must swoop down, and get the prisoners!”

It was no sooner said than the nose of the Black Hawk was pointed downward.  Onward it flew, the two captives wildly waving their hands to the rescuers.  There was no more danger from the red savages.  They had been thrown into panic and confusion, and wore rapidly disappearing into the forest.  The terrible weapons of the whites had been too much for them.

“Quick!  Get on board!” called Tom, as he brought the machinery to a stop.  The airship now rested on the ground, close to the former captives.  “Get in here!” shouted the young inventor.  “They may change their minds and come back.”

The two white persons ran toward the Black Hawk.  Then one of them—­ the smaller—­halted and cried out: 

“Why, it’s Tom Swift!”

Tom turned and glanced at the speaker.  A look of astonishment spread over his face.

“Andy Foger—­here!” gasped Tom.  “How in the world—?”

“I dink besser as ve git on der board, und dalk aftervard!” exclaimed Andy’s companion, who spoke with a strong German accent.  “I like not dose red little mans.”

In another minute the two rescued ones were safe on Tom Swift’s airship, and it had arisen high enough to be out of all danger.

“How in the world did you ever get here?” asked Tom of the lad who had so often been his enemy.

“I’ll tell you soon,” spoke Andy, “but first, Tom, I want to ask your forgiveness for all I’ve done to you, and to thank you, from the bottom of my heart, for saving us.  I thought we were going to be killed by those dwarfs; didn’t you, Herr Landbacher?”

“Sure I did.  But ve are all right now.  Dis machine is efen besser as mine vot vos lost.  Is dere anyt’ing to eats, on board, if you vill excuse me for being so bolt as to ask?”

“Plenty to eat,” said Tom, laughing, “and while you eat you can tell us your story.  And as for you, Andy, I hope we’ll be friends from now on,” and Tom held out his hand.

There was not much to tell that the reader has not already guessed.  Andy and the German, as has been explained, went abroad to give airship flights.  They were in the lower part of Egypt, and a sudden gale drove them into Africa.

For a long time they sailed on, and then their fuel gave out, and they had to descend into the jungle.  They managed to fall in with some friendly blacks, who treated them well.  The airship was useless without gasolene, and it was abandoned.

Andy and the German inventor were planning to walk to some white settlement, when the tribe they were with was attacked by the red dwarfs and vanquished.  Andy and his friend were taken prisoners, and carried to the very village where the missionaries were, just before the latter’s rescue.
