“It's queer we didn't notice it when we were up in the air,” remarked Mr. Jenks. “We've been over this place before, I'm sure of it.”
The next moment Mr. Damon uttered a cry. “Bless my watch-chain!” he exclaimed. “Look at that!”
He pointed off to the left. There, jutting out from the side of a steep mountain peak was a mass of stone—black stone—which, as the airship slowly approached, took the form and shape of a giant's head.
“That's it! That's it!” cried Tom. “The great stone head!”
“And now for Phantom Mountain and the diamonds!” shouted Mr. Jenks, as Tom let the airship slowly settle to the bottom of the valley.
CHAPTER XIII—ON PHANTOM MOUNTAIN
Out from the Red Cloud piled Tom and the others. They made a rush for the irregular mass of rock which bore so strong a resemblance to the head of some gigantic man.
“That's the one! That's the thing I saw when they were taking me along here blindfolded!” exclaimed Mr. Jenks. “I'm sure we're on the right trail, now!”
“But what gets me, though,” remarked Mr. Damon, “is why we couldn't see that landmark when we were up in the air. We had a fine view, and ought to have been able to pick it out with the telescopes.”
