"Ah-o-o-o-o-AH-O-O-O-O-o-o-o-o-o-o-o-o-o-o-o!"
It was the voice of the mountain once more.
With yells of dismay and terror the remainder of the gorilla band instantly dashed up the rocky mountain-side dragging with them, in grotesquely human fashion some of their wounded. Several of these, however, still lay on the ground and the boys put them out of their misery with a few well-directed shots. A pathetically human look lingered in the eyes of some of the injured gorillas and Harry burst out with:
"This is awful work. I'd rather fight a dozen bands of cannibals than have to do this."
"And yet," replied Frank, "if we hadn't killed them they'd have killed us."
At last the unpleasant work was over and the ivory was rapidly loaded into the aeroplane. But here an unanticipated difficulty manifested itself. Obviously the aeroplane would be too heavily laden if she attempted to carry all or even a good part of the ivory.
"Now we are stuck," cried Harry.
"Hold on," exclaimed Frank with a smile, "I anticipated this. We are going to turn the Golden Eagle into a tow-boat."
"A tow-boat?"
"That's what I said."
