The last opening was sealed and Nerado shot the great vessel into the air. Up and up, out beyond the last tenuous trace of atmosphere, on and on through space it flew with ever-increasing velocity until Nevia's gigantic blue sun had been left so far behind that it became a splendid blue-white star. Then, projectors cut off to save the precious iron whose disintegration furnished them power, for week after week Captain Nerado and his venturesome crew of scientists drifted idly through the illimitable void. Sun after sun, as visible in their ultra-instruments as though the flying vessel were moving slower than light, they studied without finding a single planet. Three months passed. Nerado had already applied the slight power which was to swing the vessel around in an immense circle, back toward his native world. In that course he was rapidly approaching a sun, an ordinary G-type dwarf, whose spectrum revealed a blaze of lines of the precious element for which he was searching. Now at close observing range--he had long since abandoned his former eager habit of studying a sun as soon as it showed the tiniest perceptible disk in his most powerful telescope--he turned on his powerful visiray beam without enthusiasm, swung it upon that very commonplace sun, and shrieked aloud in exultation. Not only one planet had that yellowish luminary--it had six, seven, eight; yes, possibly nine or ten; and several of those planets were themselves apparently centers of attraction around which were circling other tiny worlds! Nerado thrilled with joy as he applied a full retarding force, and every creature aboard that great vessel had to peer into a plate or through a telescope, before he could believe that planets other than Nevia did in reality exist! Velocity checked to the merest crawl, as space-speed goes, and with electro-magnetic detector screens full out, the Nevian vessel crept toward our sun. Finally the detectors encountered an obstacle, a conductive substance which the patterns showed conclusively to be practically pure iron. Iron--an enormous mass of it--floating alone out in space! Without waiting to investigate the nature, appearance, or structure of the precious mass, Nerado ordered power into the converters and drove an enormous softening field of force upon the object--a force of such a nature that it would condense the metallic iron into an allotropic modification of much smaller bulk; a red, viscous, extremely dense and heavy liquid which could be stored conveniently in his tanks. No sooner had the precious fluid been stored away than the detectors again broke into an uproar. In one direction was an enormous mass of iron, scarcely detectable; in another a great number of smaller masses; in a third an isolated mass, comparatively small in size. Space seemed to be full of iron, and Nerado drove his most powerful beam toward distant Nevia and sent an exultant message.
