But I had forgotten our helmet-lights. Miko must have seen them just as I pulled the trigger. The flying bullet missed him as he jumped sidewise. He dropped, but I could see him moving in the shadows to where a jutting rock gave him shelter. I fired again.

"Gregg."

I had stood up to take aim. I saw the bullet chip a bit of rock. 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 could not reach us.

Miko rose a moment later and bounded to another rock. I scrambled up, and shot at him, but missed. Then he crouched and returned my fire from his new angle; but Anita and I had shifted.

Time pa.s.sed--only a few moments. I could not see Miko momentarily.

Perhaps he was crouching; perhaps he had moved away again. He was, or had been, on slightly higher ground than the bottom of our bowl. It was dim down here where we were lying, but I feared that every moment Miko might appear and strike at us. His ray at any short range would penetrate our visor-panes, even though our suits might temporarily resist it.

"Anita--it's too dangerous here."

Had I been alone, I might perhaps have leaped up to lure Miko. But with Anita I did not dare chance it.

"We've got to get back to the camp," I told her. The audiphone brought her comment:

"Perhaps he has gone."

But he had not. We saw him again, out in a distant patch of Earthlight. He was further from us than before, but on still higher ground. We had extinguished our small helmet-lights. But he knew we were here, and possibly he could see us. His projector flashed again.

But we had again shifted, and were untouched. He was a hundred feet or more away now. His weapon was of longer range than mine. I did not answer his fire, for I could not hope to hit him at such a distance, and the flash of my weapon would help him with his aim.

I murmured to Anita, "We must get out of here."

Yet how did I dare take Anita from these concealing shadows? Miko could reach us so easily as we bounded away, in plain view in the Earthlight of the open summit! We were caught, at bay in this little bowl.

The camp from here was not visible. But out through the broken gully, beyond the staircase top, a white beam of light suddenly came up from below.

"_Haljan._"

It spelled the signal.

"_Haljan._"

It was coming from the Grantline instrument room, I knew.

I could answer it with my helmet-light, but I did not dare. I hesitated.

"Try it," urged Anita.

We crouched where we thought we might be safe from Miko's fire. My little light-beam shot up from the bowl. It was undoubtedly visible to the camp.

"_Yes? I am Haljan._"

And I added:

"_Help! Send us help._"

I did not mention Anita. Miko could doubtless read these signals. And in the camp they must have missed Anita by now. They answered:

"_Cannot_--"

I lost the rest of it. There came a flash from Miko's weapon. But it gave us confidence. He could not reach us at the moment.

The Grantline beam repeated:

"_Cannot come out. Portes broken. You cannot get in. Stay where you are--an hour or two. We may be able to repair portes._"

The portes were broken! Stay here an hour or two! But I could not hold this position against Miko that long! Sooner or later he would find a place from where he could sweep this bowl beyond possibility of our hiding. I saw him running now, well beyond my range, to ferret out another point of vantage.

I extinguished my light. What use was it to tell Grantline anything further? Besides, my light was dangerous.

But the Grantline beam spelled another message:

"_The brigand ship is coming! It will be here before we can get out to you! No lights! We will try and hide our location._"

And the signal-beam brought a last appeal to me:

"_Miko and his men will divulge where we are. Unless you can stop them_--"

The beam vanished. The lights of the Grantline camp made a faint glow that showed above the crater-edge. The glow died, as the camp now was plunged into darkness.

CHAPTER XXVII

_Anita's Plan_

We crouched in the shadows, the Earthlight filtering down to us. The skulking figure of Miko had vanished; but he was out there somewhere on the crags I was sure, lurking, maneuvering to where he could strike us with his ray. Anita's metal-gloved hand was on my arm; in my ear diaphragm her voice sounded eager and unmistakable:

"What was the signal, Gregg?"

She could not read the semaph.o.r.e lights. I told her.

"Oh Gregg, the Martian ship coming!"

Her mind clung to that as the most important thing. But not so myself.

To me there was only the realization that Anita was caught out here, almost at the mercy of Miko's ray. Grantline's men could not get out to help us, nor could I get Anita into the camp.

She added, "Where do you suppose the ship is? In telescopic view?"

"Yes--twenty or thirty thousand miles up, probably."
