Dean found the big casting in the circle of his glass. There were black figures moving near it; they were indistinct. He changed the focus—they were gone before he could get their images sharp.

But the casting! Plainly he saw its great bulk that many men had worked to ease down to the sand. It was outlined clearly now until its edge became a blur, until the sand rolled in upon it, and its black mass became a circle that shrank and shrank and vanished utterly at the last.

"It's gone!" Rawson shouted. "It sank into the sand! I saw it...."

He was running for the car. A clamor of voices was coming from below; the sound died under the thunder of the car's exhaust as Rawson gave it the gun and sent the big machine leaping toward the waiting curves.


CHAPTER V

The Attack

very light of the camp was on as Rawson and his assistant approached. A shallow depression in the sand marked the place where the big casting had been. Beyond it a hundred feet was a black swarm of men that parted as the car drew near. They had been gathered about a figure upon the sand.

Dean sensed something peculiar about that figure as the big car ploughed to a stop. He leaped out and ran forward.
