"It's an aeroplane--an airship," explained Mr. Swift.

"An airship!" exclaimed the old elephant hunter. "Say, you don't
mean that you make balloons, do you?"

"Well, they're not exactly balloons," replied Tom, as he briefly
explained what an aeroplane was, for Mr. Durban, having been in the
wilds of the jungle so much, had had very little chance to see the
wonders and progress of civilization.

"They are better than balloons," went on Tom, "for they can go where
you want them to."

"Say! That's the very thing!" cried the old hunter enthusiastically.
"If there's one thing more than another that is needed in hunting in
Africa it's an airship. The travel through the jungle is something
fierce, and that, more than anything else, interferes with my work.
I can't cover ground enough, and when I do get on the track of a
herd of elephants, and they get away, it's sometimes a week before I
can catch up to them again."

"For, in spite of their size, elephants can travel very fast, and
once they get on the go, nothing can stop them. An airship would be
the very thing to hunt elephants with in Africa--an airship and this
electric rifle. I wonder why you haven't thought of going, Tom
Swift."

"I have thought of it," answered the young inventor, "and that's why
I asked you in. I want to talk about it."
