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 glass-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 God, 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. * * * * *
