asked Ned, looking anxiously
at Tom, and then toward where his rifle stood in a corner of the
cabin.
"No, probably that drum was beaten by some of the native priests,"
explained the hunter. "The natives are very superstitious, and
likely they took us for an evil spirit, and wanted to drive us
away."
"Then we'll hustle along out of their sight," said Tom, as he went
to the pilot house to increase the speed of the airship, for he had
been letting it drift along slowly to enable the adventurers to view
the country over which they were passing. A few minutes later, under
the increased force of the machinery, the Black Hawk left the native
village, and the crowd of frightened blacks, far behind.
The travelers passed over a succession of wild stretches of forest
or jungle, high above big grassy plains, over low but rugged
mountain ranges, and big rivers. Now and then they would cross some
lake, on the calm surface of which could be made out natives, in big
canoes, hollowed out from trees. In each case the blacks showed
every appearance of fright at the sight of the airship throbbing
along over their heads.
On passing over the lake, Ned Newton looked down and cried out
excitedly:
"Look! Elephants! They're in swimming, and the natives are shooting
them! Now's our chance, Tom!"
Mr. Anderson and Mr. Durban, after a quick glance, drew back
laughing.
"Those are hippopotami!" exclaimed the old elephant man. "Good
hunting, if you don't care what you shoot, but not much sport in it.
It will be some time yet before we see any elephants, boys."
Ned was rather chagrined at his mistake, but the African travelers
told him that any one, not familiar with the country, would have
made it, especially in looking down from a great height.
They sailed along about half a mile above the earth, Tom gradually
increasing the speed of the ship, as he found the machinery to be
working well. Dinner was served as they were crossing a high grassy
plateau, over which could be seen bounding a number of antelopes.
"Some of those would go good for a meal," said Mr. Durban, after a
pause during which he watched the graceful creatures.
"Then we'll go down and get some for supper," decided Tom, for in
that hot climate it was impossible to carry fresh meat on the
airship.
Accordingly, the Black Hawk was sent down, and came to rest in a
natural clearing on the edge of the jungle. After waiting until the
fierce heat of noonday was over,
