"That is on the boundary between Peru and Bolivia?"

"Yes."

"It is a long way from Asuncion?"

"It is barely a third of the way. You will see on the map."

"Well," Ned said, after a short silence, "I may as well tell you what I want. I want to be directed to a place in the mountains where I can securely hide our aeroplane. It must be a hiding place absolutely out of sight, especially from the sky. Do you understand?"

The Indian nodded, a knowing smile on his dusky face.

"You mean to hide from the other airship?" he asked.
