"Lie flat!" he hissed. "Quick!"

He dived behind a huge mass of fire-born granite. I flung myself down beside him.

"Something is coming up the trail by the shining river. And it isn't a man! It's between us and the light; we should be able to see it."


oon I heard a curious scraping sound, and a little tinkle of metal. I caught a whiff of a powerful odor—a strange, fishy odor—so strong that it almost knocked me down.

The thing that made the scraping and the tinkle and the smell came into view. The sight of it sickened me with horror.

It was far larger than a man; its body was heavy as a horse's, but nearer the ground. In form it suggested a huge crab, though it was not very much like any crustacean I had ever seen. It was mostly red in color, and covered with a huge scarlet shell. It had five pairs of limbs. The two forward pairs had pinchers, seemingly used as hands; it scraped along on the other three pairs. Yard-long antennae, slender and luminously green, wavered above a grotesque head. The many facets of compound eyes stood on the end of foot-long stalks.

The amazing crab-thing wore a metal harness. Bands of silvery aluminum were fastened about its shell, with little cases of white metal dangling to them. In one of its uplifted claws it carried what seemed to be an aluminum bar, two feet long and an inch thick.

It scraped lumberingly past, between us and the racing stream of white fire. It passed less than a dozen feet from us. The curious fishy smell of it was overpowering, disgusting.
