Three days more--that's what I'll give it."

But the three days pa.s.sed, and no rescue ship came. The Earth was almost at the full. We tried signaling again. Perhaps it got through--we did not know. But our power was weaker now. The wall of one of the rooms sprang a leak, and the men were hours repairing it. I did not say so, but never once did I feel that our signals were seen on Earth. Those cursed clouds! The Earth almost everywhere seemed to have poor visibility.

Four of our eight days of grace were all too soon pa.s.sed. The brigand ship must be half-way here by now.

They were busy days for us. If we could have captured Miko and his band, our danger would have been less imminent. With the treasure insulated so that its Gamma rays could not betray us, and our camp in darkness, the arriving brigand ship might never find us. But Miko knew our location: he would signal his oncoming ship when it was close and lead it to us.

Three times during those days--and the days which followed them--Grantline sent out searching parties. But it was unavailing.

Miko, Moa and Coniston, with their five underlings, could not be found. We searched all the territory from the camp to the _Planetara_, and off to the foot-crags of Archimedes, and a score of miles into the flatness of the Mare Imbrium. There was no sign of the brigands. Yet we knew they could be near here--it was so easy to hide amid the tumbled crags, the ravines, the gullies, the numberless craters and pit-holes: or underground in the vast honeycombed subterranean recesses.

We had at first hoped that the brigands might have perished. But that was soon dispelled! I went--about the third day--with the party that was sent to the _Planetara_. We wanted to salvage such of its equipment, its unbroken power units, as might be available. And Snap and I had worked out an idea which we thought might be of service. We needed some of the _Planetara's_ smaller gravity-plate sections. Those in Grantline's wrecked little _Comet_ had stood so long that their radiations had gone dead. But the _Planetara's_ were still efficacious.

We secured the fragments of Newtonia.[2] But our hope that Miko might have perished was dashed. He too had returned to the _Planetara_! The evidence was clear before us. The vessel was stripped of all its power units save those which were dead and useless. The last of the food and water stores was taken. The weapons in the chart-room--the Benson curve-lights, bullet projectors, and heat-rays--had vanished.

[Footnote 2: An allusion to the element Newtonia, named in memory of the great founder of celestial mechanics, Sir Isaac Newton.

Artificially electronized, this metal element may be charged either positively or negatively, thus to attract or repell other ma.s.ses of matter. The gravity plates of all s.p.a.ce-ships were built of it.]

Other days pa.s.sed. The Earth reached the full, and began waning. The twenty-eight day Lunar night was in its last half. No rescue ship came from Earth. We had ceased our efforts to signal, for we needed all our power to maintain ourselves. The camp would be in a state of siege.

That was the best we could hope for. We had a few short-range weapons, such as Bensons, heat-rays and rifles. A few hundred feet of effective range was the most any of them could obtain. The heat-rays--in giant form one of the most deadly weapons on Earth--were only slowly efficacious on the airless Moon. Striking an intensely cold surface, their warming radiations, without atmosphere to aid them, were slow to act. Even in a blasting heat-beam a man in his Erentz helmet-suit could withstand the ray for several minutes.

We were, however, well equipped with explosives. Grantline had brought a large supply for his mining operations, and much of it was still unused. We had, also, an ample stock of oxygen fuses, and a variety of oxygen light flares in small fragile gla.s.s-globes.

It was to use these explosives against the brigands that Snap and I were working out our scheme with the gravity-plates. The brigand ship would come with giant projectors and with some thirty men. If we could hold out against them for a time, the fact that the _Planetara_ was missing would bring us help from Earth.

"A month," said Grantline. "A month at the most. If we can hold them off that long--even in a week or two help may come."

Another day. A tenseness fell on us all, despite the absorption of our feverish activities. To conserve the power, the camp was almost dark, we lived in dim, chill rooms, with just a few weak spots of light outside to mark the watchmen on their rounds. We did not use the telescope,[3] but there was scarcely an hour when one or the other of the men was not sitting on a cross-piece up in the dome of the little instrument room, casting tense searching gaze into the black, starry firmament. A ship might appear at any time now--a rescue ship from Earth, or the brigands from Mars.

Anita and Venza during these days could aid us very little save by their cheering words. They moved about the rooms, trying to inspire us; so that all the men, when they might have been humanly sullen and cursing their fate, were turned to grim activity, or grim laughter, making a joke of this coming siege. The morale of the camp now was perfect. An improvement indeed over the inactivity of the former peaceful weeks!

[Footnote 3: An old-fashioned telescope, of limited field and needing no electronic power, would have been immensely serviceable to Grantline, but his was of the more modern type.]

Grantline mentioned it to me. "We'll put up a good fight, Haljan.

These fellows from Mars will know they've had a task before they ever sail off with this treasure."

I had many moments alone with Anita. I need not mention them. It seemed that our love was crossed by the stars, with an adverse fate dooming it. And Snap and Venza must have felt the same. Among the men we were always quietly, grimly active. But alone.... I came upon Snap once with his arms around the little Venus girl. I heard him say:

"Accursed luck! That you and I should find each other too late, Venza.

We could have a mighty lot of fun in Great-New York together."

"Snap, we will!"

As I turned away, I murmured: "And, pray G.o.d, so will Anita and I."

The girls slept together in a small room of the main building. Often during the time of sleep, when the camp was stilled except for the night watch, Snap and I would sit in the corridor near the girls'

door-grid, talking of that time when we would all be back on our blessed Earth.

Our eight days of grace were pa.s.sed. The brigand ship was due--now, to-morrow, or the next day.

I recall, that night, my sleep was fitfully uneasy. Snap and I had a cubby together. We talked, and made futile plans. I went to sleep, but awakened after a few hours. Impending disaster lay heavily on me. But there was nothing abnormal nor unusual in that!

Snap was asleep. I was restless, but I did not have the heart to awaken him. He needed what little repose he could get. I dressed, left our cubby and wandered out into the corridor of the main building.

It was cold in the corridor, and gloomy with the weak blue light. An interior watchman pa.s.sed me.

"All as usual, Haljan."

"Nothing in sight?"

"No. They're looking."

I went through the connecting corridor to the adjacent building. In the instrument-room several of the men were gathered, scanning the vault overhead.

"Nothing, Haljan."

I stayed with them awhile, then wandered away. The outside man met me near the admission lock-chambers of the main building. The duty-man here sat at his controls, raising the air-pressure in the locks through which the outside watchman was coming. The relief sat here in his bloated suit, with his helmet on his knees. It was Wilks.

"Nothing yet, Haljan. I'm going up to the peak of the crater to see if anything is in sight. I wish that d.a.m.nable brigand ship would come and get it over with."

Instinctively we all spoke in half whispers, the tenseness bearing in on us.

The outside man came out of his helmet. He was white and grim, but he grinned at Wilks.

"All is usual." He tried the familiar jest at Wilks, but his voice was flat: "Don't let the Earthlight get you!"

Wilks went out through the portes--a process of no more than a minute.

I wandered away again through the corridors.

I suppose it was half an hour later that I chanced to be gazing through a corridor window. The lights along the rocky cliff-edge were tiny blue spots. The head of the stairway leading down to the abyss of the crater floor was visible. The bloated figure of Wilks was just coming up. I watched him for a moment making his rounds. He did not stop to inspect the lights. That was routine; I thought it queer that he pa.s.sed them.

Another minute pa.s.sed. The figure of Wilks went with slow bounds over toward the back of the ledge where the gla.s.site shelter housed the treasure. It was all dark off there. Wilks went into the gloom, but before I lost sight of him he came back. As though he had changed his mind he headed for the foot of the staircase which led up the cliff-face to where, at the peak of the little crater, five hundred feet above us, the narrow observatory platform was perched. He climbed with easy bounds, the light on his helmet bobbing in the gloom.

I stood watching. I could not tell why there seemed to be something queer about Wilks' actions. But I was struck with it, nevertheless. I watched him disappear over the peak of the summit.

Another minute went by. Wilks did not reappear. I thought I could make out his light on the platform up there. Then abruptly a tiny white beam was waving from the observatory platform! It flashed once or twice, then was extinguished. And now I saw Wilks plainly, standing in the Earthlight, gazing down.

Queer actions! Had the Earthlight touched him? Or was that a local signal-call which he had sent out? Why should Wilks be signalling?
