It was getting dusk when Tom, who was peering through a powerful glass, called out:

"Well, we're at the end of the plateau, and it seems to dip down into a valley just beyond here."

"Then that's the place!" cried Abe, excitedly. "Go slow, Tom."

Our hero needed no such caution. Carefully he sent the airship forward. A few minutes later they were passing over a large Eskimo village, the fur-clad inhabitants of which rushed about wildly excited at the sight of the airship.

"There they are! Them's th' beggars!" cried the old miner. "Them's th' fellows who drove me an' my partner away. But there's th' valley of gold! I know it now! Now t' fill our pockets with nuggets!"

"Are you sure this is the place?" asked Mr. Damon.

"Sartin sure of it!" declared Abe. "Put her down, Tom! Put her down!"

"All right," agreed the young inventor, as he shifted the deflection rudder. The airship began her descent into the valley. The edge of the plateau, leading down into the great depression was now black with the Eskimos and Indians, who were capering about, gesticulating wildly.

"It's quite a surprise party to 'em," observed Ned Newton.

"Yes, I hope they don't spring one on us," added Tom.
