"How are we ever going to get the tusks down the hill to the Golden
Eagle II?" asked Harry as he gazed at the formidable pile.

"I have a better plan than that," replied Frank, "we will bring the
Golden Eagle II here."

"What?" gasped both his listeners.

"Why not? It will be a ticklish job to land her on this spot, but I
think I can do it. I mean to try anyhow."

"You are risking breaking up the ship," objected Harry.

"On the other hand, if we don't get this ivory out of here in jig
time Muley-Hassan will be here with a big force and we shall
assuredly all have our throats cut."

This argument proved insurmountable, and while Ben was left by the
ivory Harry and Frank hurried down the steeps to the plateau on
which they had left the Golden Eagle II. It was the work of a few
minutes to tune her up. In a brief time from the moment they had
left the ivory cache, considering the clamber they had had, the boys
were in the air and headed for the spot where they had left the
hoard.

But as they rose into the air they were startled by the sound of a
shout and then another and another, then carne a volley of shots.

What could be the matter?
