of. Mr. Swift waved his hand and wished his son and the others good
luck, feeling a little lonesome that he could not make one of the
party. Ned was eager with excitement, and anticipation of what lay
before him. Tom Swift was thinking of what he could accomplish with
his electric rifle, and of the wonderful sights he would see, and,
as for the old elephant hunter, he was very glad to be on the move
again, after so many weeks of idleness, for he was a very active
man.

Their journey to New York was uneventful, and they found that the
parts of the airship had safely arrived, and had been taken aboard
the steamer. The little party went aboard themselves, after a day
spent in sight-seeing, and that afternoon the Soudalar, which was
the vessel's name, steamed away from the dock at high tide.

"Off for Africa!" exclaimed Tom to Ned, as they stood at the rail,

"Indeed I do. And to think of meeting you again, and on this African
steamer," and Tom's mind went back to the perilous days when his
wireless message had saved the castaways of Earthquake Island, among
whom were Mr. Anderson and his wife.

"Did I hear you say you were going to Africa?" asked Mr. Anderson,
when he had been introduced to Ned, and the others in Tom's party.

"That's where we're bound for," answered the lad. "We are going to
elephant land. But where are you going, Mr. Anderson?"

"Also to Africa, but not on a trip for pleasure or profit like
yourselves. I have been commissioned by a missionary society to
rescue two of its workers from the heart of the dark continent."

"Rescue two missionaries?" exclaimed Tom, wonderingly.

"Yes, a gentleman and his wife, who, it is reported, have fallen
into the hands of a race known as the re
