fire in the velvet black of space. A moment later he knew whose net it was, for the mining ship Fleetblast slid by him in pursuit, controlling the rocket-powered net from the remote controls in her maw. The Fleetblast sped on, unable to equal the instant acceleration that the touch of the meteor sent into the rockets of the net. But she was soon catching up. With her remote controls she was slowing the rockets of the net, as she increased her own speed. In a few minutes both ship and netted meteor would be hanging motionless alongside, the meteor caught and halted just as a small boy catches a swift ball in his cap. Sam grimaced. What would it contain when they melted it open with the heat rod? Probably nothing. Possibly mineral ore, to be refined into metal for new heat rod tips, for from this the miner fishers of the Asteroid Belt eked out their precarious existence. But perhaps—PERHAPS—there was wealth and fortune. Here might be the dream come true. Here by the luck of space, might lie one of the rare jewels of the asteroids, spawned in some once-fiery sun, and flung into space in the heart of a fragment. For this the eternal hope of man yearned, and men spent their lives fishing and mining here. For this they risked the swift and horrible infections of life in the Asteroid Belt. The visaphone sprang into life. Sam recognized the voice as that of a woman.... "Fleetblast calling Aeries...." The Fleetblast lay some fifty miles ahead, a speck of light, where the chase of her net had led her. Just to her right, closer, lay the only near ship, the Aeries. "Aeries speaking—go ahead...." Before the Aeries her net spurted four ribbons of flame. In a surge of power the Aeries was off, acceleration full, straining like a hound after a rabbit. There would be no more conversation from the Aeries, Sam knew, until the catch was landed. The woman was unaware of this development, unaware that the Aeries' flaming jets were bearing her far away. "... father is hurt ... an open wound and we have no more penicillin X...." No penicillin X! No ship took to ether for the "Belt" without a supply of that important penicillin derivative. Sam touched the controls. This was the break, this was the luck
