From this height he had a good view to the west, seeing most of the wide valley through which the red river flowed. The low vegetation they sighted from the ship thickened into clumps of good-sized trees. And among these were flying things which did not appear to be dragons.

Along the edge of the sea the cliff rose in an unbroken, perpendicular wall. Apparently the star ship had earthed in the only opening in it. For from the elevation of the sled they could sight nothing but that barrier of brilliantly hued stone dividing vegetation and low land from the heating sea.

Rogan cried out and a moment later Dard, too, cringed as a ray of light struck painfully into his eyes. It flashed up from sea level, as if a mirror had been used to direct the sunlight straight at them. Kimber brought the sled around and ventured out over the water in a sweep designed to bring them to the source of that light.

There was a scrap of beach, a few feet of sand across which the weed, driven up by the storm, lay. Kimber, with infinite caution, maneuvered to set them down there.

When the sled jolted to earth its occupants stared in open amazement at the source of the mirrored ray.

Protruding from the face of the cliff, as if from a pocket or hollow especially fashioned to contain it, was a cone-shaped section of metal. And not metal in a crude, unworked state, but of a finely fashioned and refined alloy!

Dard split a fingernail on the buckle which fastened his belt in his haste to get to the find. But Kimber was already halfway across the sand before he gained his feet. The three, not quite daring to touch, studied the peculiar object.

Kimber squatted down to peer under it. There was a thin ring of similar metal encircling the widest part of the cone, as if it rested within a tube.

“A bullet in a rifle barrel!” Rogan found a comparison which was none too reassuring. “This a shell?”

“I don’t think so.” Kimber pulled gently at the tip.
