He also found that the combination of the mineral soil and the two suns affected growth tremendously. Planting a few dried kernels of corn, he was amazed to see them take root almost instantly and reach full maturity within a few hours. He now set upon a task which he had been mulling over in his brain for some time. There were ray cannons mounted on the space liner's stern. Two of these had broken muzzles, but the third was intact. Standish went down into the bowels of the ship and found a dozen old message projectiles. Cigar-shaped objects of heat-resisting corodite, these projectiles were a part of all space crafts' emergency equipment. They were used for distress signals when radio or visiscreen equipment failed. In the hollow chamber of each of the twelve projectiles he placed the same message: Castaway. Mason Standish. Lieutenant-defense-engineer Earth. On unknown planet, somewhere near Sirius-Earth Route. December 28, 3020. He had no means of astronomical calculation. So he aimed the gun at twelve different points of the heavens and fired haphazardly. Chances of intelligent life ever finding those projectiles were millions to one against him. But whatever the odds, he must miss no opportunity. Next he made a thorough survey of the wrecked liner, carrying all usable objects to the forecastle, which swiftly took on the appearance of a storage room. As these articles began to grow in number, satisfaction and pride of ownership gripped him. It was in the midst of these labors that he was suddenly struck with an idea. Why not construct a space ship from the wrecked parts of the liner? He had six atomic motors, and surely from their wreckage he could salvage enough to build one of half the trajectory power. And with a smaller ship, he might be able to find his way back to Earth. Standish smoked a pipe over this. When morning came, he began the herculean task of dismantling the motors. Day after day he struggled with the cumbersome machinery. When this stage of the work was finally completed, he was startled to discover that six weeks of Earth time had slipped by. He then found in the machinists' quarters an electrolic saw. The tool was dull, but he managed to cut free a dozen girders for the framework of his craft. To his dismay he found them too heavy to move even with block and tackle. There was no alternative but to cut them into sections and weld them together, hoping they would stand the strain. That night the first warning of trouble came. Absently Standish had noticed a chill in the air, a more oblique slant to the twin suns. Suddenly from the jungle beyond the ravine came a low rumbling. The Earthman switched on a searchlight he had fastened on top of the forecastle. The white glare fastened itself on the wall of trees, revealed five figures advancing directly into the light. * * * * *
