But now, as we stood together on the rocks near the observatory platform, I could see the towering figure of Miko nearing the top of the stairs.

"Anita, that's Miko! We must run!"

Then I saw my projector. It lay in a bowl-like depression quite near us. I jumped for it. And as I tore loose from Anita, she leaped down after me. It was a broken bowl in the rocks, some six feet deep. It was open on the side facing the stairs—a narrow, ravinelike gully, full of gray, broken, tumbled rock masses. The little gully was littered with crags and boulders. But I could see out through it.

Miko had come to the head of the stairs. He stopped there, his great figure etched sharply by the Earthlight. I think he must have known that Coniston was the one who had fallen over the cliff, as my helmet and Coniston's were different enough for him to recognize which was which. He did not know who I was, but he did know me for an enemy.

He stood now at the summit, peering to see where we had gone. He was no more than fifty feet from us.

"Anita, lie down."

I pulled her down on the rocks. I took aim with my projector. But I had forgotten our helmet lights. Miko must have seen them just as I pulled the trigger. He jumped sidewise and dropped, but I could see him moving in the shadows to where a jutting rock gave him shelter. I fired, missing him again.

I had stood up to take aim. Anita pulled me sharply down beside her.

"Gregg, he's armed!"

It was his turn to fire. It came—the familiar vague flash of the paralyzing ray. It spat its tint of color on the rocks near us, but did not reach us.
