No mean prize, that. Half the value of ship and cargo! More than he was apt to earn in years of mining the meteor-belt. With new anxiety, he measured the relative motion of the gleaming ship. It was going to pass ahead of him. And very soon. No more time for speculation. It was still uncertain whether it would come near enough so that he could get a line to it. Rapidly he unslung from his belt the apparatus he used to capture meteors. A powerful electromagnet, with a thin, strong wire fastened to it, to be hurled from a helix-gun. He set the drum on which the wire was wound upon the metal at his feet, fastened it with its magnetic anchor, wondering if it would stand the terrific strain when the wire tightened. Raising the helix to his shoulder, he trained it upon a point well ahead of the rushing flier, and stood waiting for the exact moment to press the lever. The slender spindle of the ship was only a mile away now, bright in the sunlight. He could see no break in her polished hull, save for the dark rows of circular ports. She was not, by any means, completely wrecked. He read the black letters of her name. _Red Dragon._ The name of her home port, below, was in smaller letters. But in a moment he made them out. San Francisco. The ship then came from the Earth! From the very city where Thad was born! * * * * * The gleaming hull was near now. Only a few hundred yards away. Passing. Aiming well ahead of her, to allow for her motion, Thad pressed the key that hurled the magnet from the helix. It flung away from him, the wire screaming from the reel behind it. Thad's mass of metal swung on past the ship, as he returned to the rocket and stopped its clattering explosions. He watched the tiny black speck of the magnet. It vanished from sight in the darkness of space, appeared again against the white, burnished hull of the rocket ship. For a painful instant he thought he had missed. Then he saw that the magnet was fast to the side of the flier, near the stern. The line tightened. Soon the strain would come upon it, as it checked the momentum of the mass of iron. He set the friction brake. Thad flung himself flat, grasped the wire above the reel. Even if the mass of iron tore itself free, he could hold to the wire, and himself reach the ship. He flung past the deserted vessel, behind it, his lump of iron swung like a pebble in a sling. A cloud of smoke burst from the burned lining of the friction brake, in the reel. Then the wire was all out; there was a sudden jerk. And the hard-gathered sphere of metal was gone--snapped off into space. Thad clung desperately to the wire, muscles cracking, tortured arms almost drawn from their sockets. Fear flashed over his mind; what if the wire broke, and left him floating helpless in space? * * * * *
