"Was today a rough day with Buster, dear?" asked Anne.

"Mm-m-mm," answered John.

"That's too bad, dear," said Anne. "I think you work much too hard--what with this dreadful invasion and everything. Why don't you take a vacation? You really need one, you know. You look so tired."

"Mm-m-mm," answered John.

"Well, if you won't, you won't. Though goodness knows you won't be doing anyone any good if you have a breakdown, as you're likely to have, unless you take it a little easier. What was the trouble today, dear? Was the Oracle being obstinate again?"

"Mm-m-mm," answered John.

"Well, then, dear, why don't you tell me all about it? I always think that things are much easier to bear, if you share them. And then, two heads are always better than one, aren't they? Maybe I could help you with your problem."

While Anne's voice gushed, her violet eyes studied his exhausted face with intelligence and compassion.

John sighed deeply, then sat up slowly and opened his eyes to look into Anne's. She glanced away, her own eyes suddenly vague and soft-looking, now that John could see them. "The trouble, darling," he said, "is that I have to go to an emergency council meeting this evening with another one of those ridiculous riddles that Buster gave me as the only answer to the most important question we've ever asked it. And I don't know what the riddle means."

Anne slid from the arm of the chair and settled herself onto the floor at John's feet. "You should not let that old Oracle bother you so much, dear. After all, you built it yourself, so you should know what to expect of it."

"When I asked it how to preserve Earth from the invaders it just answered 'A Stitch in Time Saves Nine,' and wouldn't interpret it."

"And that sounds like very good sense, too," said Anne in earnest tones. "But it's a little late, isn't it? After all, the invaders are already invading us, aren't they?"

"It has some deeper meaning than the usual one," said John. "If I could only figure out what it is."

"What's what?"

"Stitching, silly. I already asked you."

"Darling," said John with reasonable patience, "I must have explained inter-planar travel to you at least a dozen times."

"And you always make it so crystal clear and easy to understand at the time," said Anne. She wrinkled her smooth forehead. "But somehow, later, it never seems quite so plain when I start to think about it by myself. Besides, I like the way your eyebrows go up and down while you explain something you think I won't understand. So tell me again. Please."

Bristol grinned suddenly. "Yes, dear," he said. He paused a moment to collect his thoughts. "First of all, you know that there are two coexistent universes or planes, with point-to-point correspondence, but that these planes are of very different size. For every one of the infinitude of points in our Universe--which we call for convenience the 'alpha' plane--there is a single corresponding point in the smaller or 'beta' plane."

Anne pursed her lips doubtfully. "If they match point for point, how can there be any difference in size?" she asked.

John searched his pockets. After a little difficulty, he produced an envelope and a pencil stub. On the back of the envelope, he drew two parallel lines, one about five inches long, and the other about double the length of the first.

"Actually," he said, "each of these line segments has an infinite number of points in it, but we'll ignore that. I'll just divide each one of these into ten equal parts." He did so, using short, neat cross-marks.

"Now I'll establish a one-to-one correspondence between these two segments, which we will call one-line universes, by connecting each of my dividing cross-marks on the short segment with the corresponding mark on the longer line. I'll use dotted lines as connectors. That makes eleven dotted lines. You see?"

Anne nodded. "That's plain enough. It reminds me of a venetian blind that has hung up on one side. Like ours in the living room last week that I couldn't fix, but had to wait until you came home."

"Yes," said John. "Now, let us call this longer line-segment an 'alpha' universe; an analogue of our own multi-dimensional 'alpha' universe. If I move my pencil along the line at one section a second like this, it takes me ten seconds to get to the other end. We will assume that this velocity of an inch a second is the fastest anything can go along the 'alpha' line. That is the velocity of light, therefore, in the 'alpha' plane--186,000 miles a second, in round numbers. No need to use decimals."

He hurried on as Anne stirred and seemed about to speak. "But if I slide out from my starting point along a dotted line part way to the 'beta' universe--something which, for reasons I can't explain now, takes negligible time--watch what happens. If I still proceed at the rate of an inch a second in this inter-planar region, then, with the dotted lines all bunched closely together, after five seconds when I switch along another dotted line back to my original universe, I have gone almost the whole length of that longer line. Of course, this introduction of 'alpha' matter--my pencil point in this case--into the inter-planar region between the universes sets up enormous strains, so that after a certain length of time our spaceship is automatically rejected and returned to its own proper plane."

"Could anybody in the littler universe use the same system?"

John laughed. "If there were anybody in the 'beta' plane, I guess they could, although they would end up traveling slower than they would if they just stayed in their own plane. But there isn't anybody. The 'beta' plane is a constant level entropy universe--completely without life of its own. The entropy level, of course, is vastly higher than that of our own universe."

John Shrugged his shoulders and smiled. "Now," he said, "if I want to get somewhere fast, I just start off in the right direction, and switch over toward 'beta.' When 'beta' throws me back, a light-year or so toward my destination, I just switch over again. You see, there is a great deal more difference in the sizes of Alpha universe and Beta universe than in the sizes of these alpha and beta line-segment analogues. Then I continue alternating back and forth until I get where I want to go. Establishing my correct velocity vector is complicated mathematically, but simple in practice, and is actually an aiming device, having nothing to do with how fast I go."

He hesitated, groping for the right words. "In point of fact, you have to imagine that corresponding points in the two universes are moving rapidly past each other in all directions at once. I just have to select the right direction, or to convince the probability cloud that corresponds to my location in the 'alpha' universe that it is really a point near the 'beta' universe, going my way. That's a somewhat more confused way of looking at it than merely imagining that I continue to travel in the inter-planar region at the same velocity that I had in 'alpha,' but it's closer to a description of what the math says happens. I could make it clear if I could just use mathematics, but I doubt if the equations will mean much to you.

"At any rate, distance traveled depends on mass--the bigger the ship, the shorter the distance traveled on each return to our own universe--and not on velocity in 'alpha.' Other parameters, entirely under the control of the traveler, also affect the time that a ship remains in the inter-planar region.

"There are refinements, of course. Recently, for example, we have discovered a method of multi-transfer. Several of the transmitters that accomplish the transfer are used together. When they all operate exactly simultaneously, all the matter within a large volume of space is transferred as a unit. With three or four transmitters keyed together, you could transfer a comet and its tail intact. And that's how inter-planar traveling works. Clear now?"

"And that's why they call it 'stitching,'" said Anne with seeming delight. "You just think of the ship as a needle stitching its way back and forth into and out of our universe. Why didn't you just say so?"

"I have. Many times. But there's another interesting point about stitching. Subjectively, the man in the ship seems to spend about one day in each universe alternately. Actually, according to the time scale of an observer in the 'alpha' plane, his ship disappears for about a day, then reappears for a minute fraction of a second and is gone again. Of course, one observer couldn't watch both the disappearance and reappearance of the same ship, and I assume the observers have the same velocity in 'alpha' as does the stitching ship. Anyway, after a ship completes its last stitch, near its destination, there's a day of subjective time in which to make calculations for the landing--to compute trajectories and so forth--before it actually fully rejoins this universe. And while in the inter-planar region it cannot be detected, even by someone else stitching in the same region of 'alpha' space.

"That's one of the things that makes interruption of the enemy ships entirely impossible. If a ship is in an unfavorable position, it just takes one more quick stitch out of range, then returns to a more favorable location. In other words, if it finds itself in trouble, it can be gone from our plane again even before it entirely rejoins it. Even if it landed by accident in the heart of a blue-white star, it would be unharmed for that tiny fraction of a second which, to the people in the ship, would seem like an entire day.

"If this time anomaly didn't exist, it might be possible to set up defenses that would operate after a ship's arrival in the solar system but before it could do any damage; but as it is, they can dodge any defense we can devise. Is all that clear?"

Anne nodded. "Uh-hunh, I understood every word."

"There is another thing about inter-planar travel that you ought to remember," said Bristol. "When a ship returns to our universe, it causes a wide area disturbance; you have probably heard it called space shiver or the bong wave. The beta universe is so much smaller than our own alpha that you can imagine a spaceship when shifted toward it as being several beta light-years long. Now, if you think of a ship, moving between the alpha and beta lines on this envelope, as getting tangled in the dotted lines that connect the points on the two lines, that would mean that it would affect an area smaller than its own size on beta--a vastly larger area on alpha.

"Well, dear," said Anne.

"As usual, I'm sure you have made me understand perfectly. This time you did so well that I may still remember what stitching is by tomorrow. If the Oracle means anything at all by his statement, I suppose it means that we can use stitching to help defend ourselves, just as the invaders are using it to attack us. But the whole thing sounds completely silly to me. The Oracle, I mean."

Anne Bristol stood up, put her hands on her shapely hips and shook her head at her husband. "Honestly," she said, "you men are all alike. Paying so much attention to a toy you built yourself, and only last week you made fun of my going to a fortune teller. And the fuss you made about the ten dollars when you know it was worth every cent of it. She really told me the most amazing things. If you'd only let me tell you some of...."

"Darling!" interrupted John with the hopeless patience of a harassed husband. "It isn't the same thing at all. Buster isn't a fortune teller or the ghost of somebody's great aunt wobbling tables and blowing through horns. And Buster isn't just a toy, either. It is a very elaborate calculating machine designed to think logically when fed a vast mass of data. Unfortunately, it has a sense of humor and a sense of responsibility."

Bristol shook his head. "Your idea may be sound, even if it is a little bloodthirsty coming from someone who won't even let me set a mouse-trap, but it won't work. First, we don't know where their home planets are and second, they have more ships than we do. It might be made to work, but only if we could get enough time. And speaking of time, I've got to meet with the Council as soon as we finish eating. Is dinner ready?"

After a leisurely meal and a hurried trip across town, John Bristol found himself facing the other members of Earth's Council at the conference table.

"I have been able to get an answer from the computer," he told them without preamble. "It's of the ambiguous type we have come to expect. I hope you can get something useful out of it; so far it hasn't made much sense to me. It's an old proverb. Its advice is undoubtedly sound, as a generality, if we could think of a way of using it."

The President of the Council raised his long, lean-fingered hand in a quick gesture. "John," he said, "stop this stalling. Just what did the Oracle say?"

"It said, 'A Stitch in Time Saves Nine.'"

"Is that all?"

"Yes, sir. According to the calculator, that gives us the best opportunity to save ourselves from the invaders."

The President absently stroked the neat, somewhat scanty iron-gray hair that formed into a triangle above his high forehead and rubbed the bare scalp on each side of the peak vigorously and unconsciously with his knuckles. "In that case," he said at last, "I suppose that we must examine the statement for hidden meanings. The proverb, of course, implies that rapid action, before a trouble has become great, is more economical than the increased effort required after trouble has grown large. Since our troubles have already grown large, that warning is scarcely of value to us now."

The War Secretary, who had grown plump and purple during a quarter of a century as a member of the Council, inclined his head ponderously toward the President. "Perhaps, Michael, the Oracle means to tell us that there is a simple solution which, if applied quickly, will make our present difficulty with the invaders a small one."

Bristol, his fists clenched, spoke hotly. "Sir, that is the stupidest, the most...."
