“Yes. Yonder peak was north by west. Here—here was about the spot where we camped. The gold mound should be three miles or more in that direction out in the lake.”
These facts established, the interest of all reached fever height. The air-ship was held stationary over that spot.
A discussion was now held as to the best course to be pursued.
“Of course we can do no better than to wait for the disappearance of the lake,” said Nicodemus. “That may happen at any time.”
“Is there any regularity to the event?” asked Frank.
“That I cannot say,” replied the captain. “We were here but a few weeks, and the lake disappeared and reappeared only once in that time.”
“I have to suggest, then,” said Frank, “that we sail over to that distant peak and wait there until some change comes.”
The peak in question overhung the lake, so that its disappearance could be instantly noted.
The plan was adopted.
Soon the Spectre was resting upon this mountain height. A good spot was found for the air-ship to rest.
