“We’ll put her together here,” said Tom, “give her a good try-out to see that she works well, and then pack her up for shipment to the African coast by steamer. We’ll go on the same ship, and when we arrive we’ll put the Black Hawk together again, and set sail for the interior.”

“Good idea,” commented Mr. Durban. “Now, if you’ve no objections, I’m going to do a little practice with the electric rifle.”

“Have you heard the news?”

“What news?” inquired the young inventor.

“About Andy Foger. He and his aeroplane are lost!”

“Lost!” cried Tom, for in spite of the mean way the bully had treated him our hero did not wish him any harm.

“Well, not exactly lost,” went on Ned, as he held out the paper to Tom, “but he and his sky-craft have disappeared.”
