A QUARTER OF A MILLION LIGHT YEARS
"Our civilization,"  Zezdon Afthen, "is   on the knowledge of the mind. We cannot have criminals, for the man who plots  is surely  out by his thoughts. We cannot have  politicians and  rulers.
"It is a peaceful civilization. The Ancient Masters  and  War with a  aversion. But they did not make our  cowards,  peaceful intelligence. Now we must  for our homes, and my  will  mightily. But we need weapons.
"But my  has little to do with our race. I will tell the  of our  and of the Ancient Ones later when the time is more auspicious.
"Four months ago, our     powerful  from space. That  only  that a new,    had  appeared  a billion miles of our world. The     it as  from the third  of our system. Zezdon Fentes, with my aid, set up some special apparatus, which would  up   and make them visible. We had used this  to see not only what an enemy looked upon, but also what he saw in that  thing, the  of the mind, the  of the past and the future. But while the thought-amplification device was powerful, the new  were hard to  from each other.
"It was done finally, when all but one man slept. That one we were  to   to. After that we   him at any time. He was the commander. We saw him  the ship, we saw the ship, saw it  over the barren,  surface of that world. We saw other men come in and go out. They were  men. Short, squat,  men. Their arms were  and stocky. But their  was enormous, unbelievable. We saw them  solid  of  as thick as my arm. With perfect ease!
"Their  were  active, but they were evil,  evil. Nothing that did not  them counted. At one time our   dead, and we  that the  had  us, but we saw what  a little later. The second in  had killed him.
"We saw them  the world,  their way across it,   suits, yet, for all the   of that world,  about like  balls,  and jumping where they wanted. Their  would drive out like pistons, and they  up and through the air.
"They were  while they  those examinations, and slept  at night.
"Then one night there was a conference. We saw then what they intended. Before we had   to  them. Now we were  that we had failed.
"We saw their ship  (in the  of the second in command) and sail out into space, and  toward our world. The world  larger, but it was  sketched in, for they did not know our world well. Their  did not have great power as your electric  have.
"We saw them  the planet. We saw them plan to  any people they  with a  which was as follows: 'the  which makes all parts move as one.' We  not  and  not interpret. Thoughts  our knowledge have, of course, no meaning,  when our    them, and  them to us."
"The Molecular ray!"  Morey in surprise. "They will be an enemy."
"You know it! It is familiar to you! You have it? You can  it?" asked Zezdon Afthen excitedly.
"We know it, and can  it, if that is all they have."
"They have more—much more I fear,"  Zezdon Afthen. "At any rate, we saw what they intended. If our world was inhabited, they would  every one on it, and then other men of their  were to  in on their great ships, and settle on that largest of our worlds.
"We had to stop them so we did what we could. We had powerful machines, which would  and  our thoughts. So we  our thought-waves, and  in the mind of their leader that it would be wise to land, and learn the  of the civilization, and the  to be met. Also, as the ship  nearer, we  him decide on a  spot we had prepared for him.
"He   that the  were not his own. Only the ideas came to him,  to  from his own mind.
"He landed—and we used our one weapon. It was a thing left to one group of  when the Ancient Masters left us to  for ourselves. What it was, we  knew; we had  used it in the fifteen thousand years since the Great Masters had passed—never had to. But now it was  out, and   great  of  in a   where the ship of the enemy would land. When it landed, we  the  of the machine on it, and the   it swiftly, and a  of the beam's  was  as the  was  through a small circle in the  plane. The machine  backward, and though it was so  that a  amount of labor had been  to  it there, the push of the pencil of  we sent out  it  against a    it as though it were some child's toy. It  to  for  a second,  two. In that time two great  had been cut in the enemy ship,  fifteen  across, that ran  through the  as though a die had cut through the metal of the ship,  out a  of metal.
"There was a  concussion, and a  as the air  out of the ship. It did not take us long to  that the enemy were dead. Their terrible,     in the ship. Most of the men we were able to recognize, having  them in the mentovisor. But the colors were distorted, and their  were peculiar. Indeed, the whole ship  strange. The only time that   did  normal about that  thing, when the  of it  what they were, when the  did not  out of proportion, out of shape, twisted, was when on a trial  we  very close to our sun."
Arcot   and looked at Morey. Morey nodded. "Probably right. Don't interrupt."
"That you  something, I understood, but the  themselves were   to me. You know the explanation?" asked Zezdon Afthen eagerly.
"We think so. The ship was   on a world of  size. Those men, their stocky,   and arms, their entire  and their  for the largest of your planets, would  that. Their own world was   larger—they were  to wear pressure   on that large world, and  jump all over, you said. On so  a  as their native world  to be, the  would be so  as to  space. Geometry, such as yours  to be, and such as ours was,   be developed, for you assume the  of a  line, and of an  plane surface. These  cannot  in space, but on small worlds,  from the  sun's mass, the  approach that without   to make the error obvious. On so  a  as their world the space is so  that it is at once  that no  line exists, and that no plane exists. Their  would  be like ours. When you  close to your sun, the  was  to  space into a  of the natural  on their home planet, then your  and the ship met a  condition which  it  more or less normal, not so   to you.
"But continue." Arcot looked at Afthen interestedly.
"There were none left in their ship now, and we had been  in  the  hole, that it should not  the propulsive machinery. The second  was accidental,  to the shift of the machine. The machine itself was  now,  by its own reaction. We  that any pencil of  powerful  to do what we wanted, would tear the machine from its  unless  with great   into the solid rock.
"The second  had been  to the rear, and had, by ill-luck, cut out a  of the  apparatus. We  not repair that, though we did succeed at last in  the great  into place. We  to cut them, and put them  in sections. Our   and  did not  them. Their weight was unbelievable, and yet we  succeeded in  the  into the  of the ship. The  missing material did not  more than a  cut,  as wide as one of your credit-discs. You   the thin piece of metal in  them, but not so much as your finger.
"Those  we  tight with our best steel,  a   over on each  of the cut, and as the  metal cooled, it was  against the   with  force. The joints were perfectly airtight.
"The  proper were repaired to the  possible extent. It was a  task, for we must only  at what  should be  together. Much  had been done by the  air as it left, for it  the machines, too, and they were not designed to  the  air pressure that was on them when the pressure in the ship escaped. Many of the  had been  open, and these we  repair when we had the necessary  and  their  from the remnants, or     in the stock rooms.
"Once we  the  things. This will  you what we  with. They were the  poles—two generators,  together in the  way. There was a  crash when the  was thrown, and   of electric   from one of them. Two men were killed,  in an instant,  the  one might  were killed in that  of heat. Everything save the  metal and clear   ten  of it was   out. And there was a  link that gave. The  was ruined. One was left, and  small  generators.
"Eventually, we did the job. We  the machine work. And we are here.
"We have come to  you, and to ask aid. Your  also has a large planet,  smaller than the largest of our system, but yet attractive. There are  50,000   in this universe, according to the records of the Invaders. Their world is not of this system. It is the World Thett, sun Antseck, Universe Venone. Where that is, or  what it means, we do not know. Perhaps you understand.
"But they  your world, and its address, according to their records, was World 3769-8482730-3. This, I believe, means, Universe 3769, sun 8482730, world 3. They have been  this  now for nearly three centuries. It was close to 200 years ago that they visited your world—two hundred years of your time."
"This is 2129—which makes it about the year 1929-30 that they  around here investigating. Why haven't they done anything?" Arcot asked him.
"They waited for an  time. They are  now, for  they visited your world, and were   to  the  progress your people have made. They  to make an  attack on all worlds  to be  populated. They had  the mistake of  one  learn too much; they cannot  to let it  again.
"There are only twenty-one  worlds known, and their thousands of  have already  nearly all the   of this universe, and much of the  rings. They have  a  in this universe. Where I do not know. That, alone, was  mentioned in the records. But of all peoples, they  only your world.
"There is one  in the   older than yours, but they are a sleeping people. Long ago their  decayed. Still, now they are not  from you, and  it will be  the  days needed to learn more about them. We have their  and can take you there. Their world circles a  star—"
"Not any more," laughed Morey grimly. "That's another  for the enemy. They had a little jog, and they  are wide  now. They are  for big things, and they are going to do a lot."
"But how do you know these things? You have ships that can go from  to planet, I know, but the records of the enemy said you  not  the  of your sun. They alone  that secret."
"Another  for them," said Morey. "We can—and we can move  than your ship, if not  than they. The people of the  star have moved to a very live star—Sirius, the  in our heavens. And they are as much alive now as their new sun. They can move  than light, also. We had a little  a while back, when their star passed close to ours. They came off second best, and we haven't spoken to them since. But I think we can make valuable  there."
For all Morey's  manner, he  the terrible  of this announcement. A  which had been able to  the   of  space in the days when Terrestrians were still  the airplane—and already they had  Jupiter, and planned their colonies! What  had come? They had  rays,  rays, the energy of matter, then—what else had they now? Lux and Relux, the two  metals,  of  light,   than anything of   in nature,  infusible, totally  chemically, one a perfect  of light and of all  in space, the other a perfect  of all radiations—save  rays. Made into the condition of  by the action of special  in its  from light,   were, unfortunately, able to  it into perfectly   metal, when the  value was gone.
They had that. All Earth had, perhaps.
"There was one other  of some importance, the others were semi-civilized. They  us in a position  these  and the high races—yours, those of the  star, and those of world 3769-37:478:326:894-6. Our science had been  two hundred or so years ago.
"This other  was at a great  from us,  than yours, and  not  as  as yours. They cannot  to other worlds, save in small ships   by fire, which the Thessians have called a 'hopelessly  and   thing to  in.'"
"Rockets,"  Morey. "Our  ship was part rocket."
Zezdon Fentes smiled. "But that is all. We have  you warning, and our plea. Can you help us?"
"We cannot answer that. The Interplanetary Council must act. But I am  that it will be all we can do to protect our own world if this enemy  soon, and I  they will. Since they have a  in this universe, it is  to  that all ships did not report  to the home world at  intervals. That one is missing will soon be discovered, and it will be sought. War will start at once. Three months it took you to  us—they should come soon.
"Those men who left will be on their way  from the home world from which they came. What do you call your planet, friend?"
"Ortol is our home,"  Zezdon Inthel.
"At any rate, I can only  you that your world will be   that will permit your people to  themselves and I will  you to your home  twenty-four hours. Your ship—is it in the system?"
"It  on the second  of the fourth planet,"  Zezdon Afthen.
"Signal them, and tell them to land where a  of  light,  red and blue,  up from—this point on the map." Arcot pointed out the spot in Vermont where their private  and laboratory were.
He  to the others, and in rapid-fire English,  his plans. "We need the help of these people as much as they need ours. I think Zezdon Fentes will  here and help you. The others will go with us to their world. There we shall have  of work to do, but on the way we are going to stop at Mars and  up that valuable ship of theirs and make a   for possible new weapons, their  of speed-drive, and their regular space-drive. I'm  to make a  right now, that I can  both. Their regular drive is a  drive with lead   for the energy,    for the heating, and a drive much like ours. Their speed drive is a time  apparatus, I'll wager. Time  offers an easy  of speed. All speed is relative—relative to other bodies, but also to time-speed. But we'll see.
"I'm going to  some  to  the biggest  power  I can  into the  of the Ancient Mariner, and pack in a ray-screen. It will be useful. Let's move."
"Our ship," said Zezdon Afthen, "will land in three of your hours."
