"No!" cried Sherman, but she was already running out across the field. The snout of the machine lifted toward her as though to deliver a blast, then rose and discharged another beam of blue light. Sherman heard one of the birds scream in answer, saw it sweep down on soaring pinions, and in a single motion snap the dancer up and away. The shimmering fighting machine swung round and turned back toward the road.

He lay still until he was sure it had gone, then, moving carefully for fear of the terror from the skies, crawled to the next bungalow. It yielded treasure-trove in the shape of a flashlight and a serviceable revolver, and securing a sheet from one of the beds to wrap around him as a loin-cloth, he set out to trudge to New York.

After a time it occurred to him that the disaster had taken place not because they were in a car, but because it had been driven unreasonably fast, and without precaution. He looked for and ultimately found another one, and keeping to the back streets and driving slowly, worked his way toward the city again. Then another idea came to him—Newark had an airport as well as New York and it was far nearer. He changed the direction of his advance, swinging west to avoid the long bridges over the Passaic River. Bridges were focal points; the birds would surely watch them, as intelligent as they were.

Late in the afternoon he spied one of them, far ahead and flying southward, but took no chances. He drew his car up to the side of the road and remained motionless for long after it had disappeared. When evening came on, he had already reached the outskirts of the city and could proceed without headlights.

Newark was a dead city, the diminished purr of the motor ringing curiously loud in the silent streets. Their complication bothered him; he was unfamiliar with the town and his flashlight gave out long before he reached his destination. But he kept steadily on, certain that the airport was somewhere at the south and east of the city. Toward the later evening a fine, cold rain began to fall, congealing to ice on the streets and on his metallic body.

The airport was just as he had remembered it on the first day of his awakening—it now seemed uncountable ages in the past. The little sports plane still stood on the platform, its torn wing dangling. The hangars were all locked; he was an inefficient burglar and spent an hour or two breaking one open and when he did, found nothing but a tri-motored monster quite beyond his powers to get out, and a rocket-plane requiring special fuel that he did not have. The next hangar yielded an autogiro and a training machine. He had no watch, but was sure that the night was passing fast, and not wishing to be abroad by daylight with an airplane, decided to chance it on the autogiro. Luckily she was full of fuel, and everything seemed tight. With some labor he removed the chocks and managed to wheel the machine out.

Not till he had it in the air did the thought of what direction he was to take occur to him. Boston—New York—Philadelphia—Chicago, he canvassed the possibilities. What was it Marta Lami had said—something about one of the fighting machines heading south? And he remembered how the astronomers had predicted that the comet would fall, probably, somewhere in New York State. If there were a borderline along which Lassans were meeting humans in any kind of conflict it was most likely to lie southward. With this thought in mind, he turned his plane to the south, and keeping the white line of foam along the coast beneath him as a guide, began to let her out.

The ceiling was low; between clouds and fitful squalls of rain flying was difficult and the weight of Sherman's mechanical body seemed to make the machine move loggily. It must have been all of an hour and three quarters later that he saw beneath him the tossing whitecaps of Great Bay, with the ribbon of Wading River running back into the distance. Just beyond, he knew, lay Atlantic City. He was debating with himself whether to land on the beach there or hop across to the Philadelphia airport when, sharp and clear from somewhere ahead and below him, came the sound of gunfire. He tried for altitude, but only ran into clouds. Nevertheless the sound was unmistakable, and as he approached it became clearer and more pronounced, a long intermittent beat, heavy guns and light, mingled together, off to the right. There was fighting going on!

Exulting in his escape from the Lassans and in the fact that he could take their opponents information that would be of value, he swung the autogiro toward the sounds that became clearer every minute. He was getting right over them now, he thought; he could see red flashes along the horizon. Down there they were locked in battle—men and Lassans, his own people and the invaders from far-away Rigel.

Suddenly a beam of the light-ray leaped from the ground. Sherman thought it was directed at him; tried to loop the plane and cursed as he remembered autogiros wouldn't loop; then saw that the light was after all, not turned in his direction, but at some object on the ground. He banked the plane over and swung lower. Undoubtedly a Lassan fighting machine—and the beam was hitting things, things large and solid, for they collapsed under the stabbing ray. A red flame rose over the wreck; the roar of an explosion reached his ears. The battle-line!
