This move was decided upon at once.
Harding directed the course of the air-ship. Darkness was fast coming on, and after drifting for a time over the mountain peaks Frank decided that it would be better to wait for the light of another day.
Harding declared that the cavern was now not more than twenty miles distant.
“We will make that in very quick time in the morning,” declared Frank. “Certainly we can do little in this gloom.”
The sky was cloudy and the darkness which settled down was most intense.
But upon the bow of the air-ship was an electric searchlight.
With this Frank illumined the face of the country below.
He selected what he believed would be a good spot.
It was an open spot in a valley high up in the lofty Andes.
Here the air-ship was allowed to descend and rest upon the ground.
