"And this thing isn't here either. Are you?"
"There is no need to experiment. I, and our ship, are present only as what might be called temporal echoes. Matter cannot be moved through time, that is an impossibility, but the concept of matter can be temporally projected. I am sure that this is too technical for you. ."
"You're doing great so far. Carry on."
"Our projections are here in a real sense to us, though we can only be an image or a sound wave to any observers in the time we visit. Immense amo*nits of energy are required and almost the total resources of our civilization are involved in this time transfer."
"Why? And the truth for a change. No more fairy godmother and that kind of malarkey."
"I regret the necessity to use subterfuge, but the secret is too important to reveal casually without attempting other means of persuasion."
"Now we get to the real story." Don sat down and crossed his legs comfortably. "Give."
"We need your aid, or our very society is threatened. Very recently on our time scale strange disturbances were detected by our instruments. Ours is a simple saurian existence, some million or so years in the future, and our race is dominant. Yours has long since vanished in a manner too horrible to mention to your young ears. Something is threatening our entire race and research quickly uncovered the fact that we are about to be overwhelmed by a probability wave and wiped out, a great wave of negation sweeping toward us from our remote past."
"You wouldn't mind tipping me off to what a probability wave is, would you?"
"I will take an example from your own literature. If your grandfather had died without marrying, you would not have been born and would not now exist."
"But I do."
"The matter is debatable in the greater xan-probility universe, but we shall not discuss that now. Our power is limited. To put the affair simply, we traced our ancestral lines back through all the various mutations and changes until we found the individual protolizard from which our line sprung.”
"Let me guess." Don pointed at the cage. "This is the one?"
"She is." 17 spoke in solemn tones, as befitted the moment. Justas somewhen, somewhere there is a prototarsier from which your race sprung, so is there this temporal mother of ours. She will bear young soon, and they will breed and grow in this pleasant valley. The rocks near the lake have an appreciable amount of radioactivity, which will cause mutations, the centuries will roll by and, one day, our race will reach its heights of glory.
"But not if you don't open that cage."
Don rested his chin on his fist and thought. "You're not putting me on anymore? This is the truth?"
17 drew herself up and waved both arms — or front legs — over her head. "By the Saur of All, I promise," she intoned. "By the stars eternal, the seasons vernal, the clouds, the sky, the matriarchal I—"
"Just cross your heart and hope to die, that will be good enough for me."
The lizardoid moved its eyes in concentric circles and performed this ritual.
"Okay then, I'm as softhearted as the next guy when it comes to wiping out whole races."
Don unbent the piece of wire that sealed the cage and opened the top. The chameleon rolled one eye up at him and looked at the opening with the other. 17 watched in awed silence and the time vehicle bobbed closer.
"Get going.” Don said, and shook the lizard out into the grass.
This time the chameleon took the hint and scuttled away among the bushes, vanishing from sight.
"That takes care of the future," Don said. "Or the past from your point of view."
17 and the time machine vanished silently and Don was alone again on the path.
"Well you could of at least said thanks before taking off like that. People have more manners than lizards any day I'll tell you that."
He picked up the now-empty cage and his schoolbag and started for home.
He had not heard the quick rustle in the bushes, nor did he see the prowling tomcat with the limp chameleon in its jaws.
Brave Newer World
Livermore liked the view from the little white balcony outside his office, even though the air at this height, at this time of year, had a chill bite to it. He was standing there now, trying to suppress a shiver, looking out at the new spring green on the hillsides and the trees in the old town. Above and below him the white steps of the levels of New Town stretched away in smooth elegance, a great A in space with the base a half-mile wide, rising up almost to a point on top. Every level fringed with a balcony, every balcony with an unobstructed view. Well designed. Livermore shivered again and felt the loud beat of his heart; old valves cheered on by new drugs. His insides were as carefully propped up and as well designed as the New Town building. Though his outsides left a lot to be desired. Brown spots, wrinkles, and white hair, he looked as weathered as the homes in Old Town. It was damned cold, and the sun went behind a cloud. He thumbed a button and when the glass wall slid aside, went back gratefully to the purified and warmed air of the interior.
"Been waiting long?" he asked the old man who sat scowling in the chair on the far side of his desk.
"You asked, Doctor. I was never one to complain but—"
"Then don't start now. Stand up, open your shirt, let me have those records. Grazer, I remember you. Planted a kidney seed, didn't they? How do you feel?"
"Poorly, that's the only word for it. Off my feed, can't sleep, when I do I wake up with the cold sweats. And the bowels! Let me tell you about the bowels. . ahhh!"
Livemore slapped the cold pickup of the stethoscope against the bare skin of Grazer's chest. Patients liked Dr. Livermore but hated his stethoscope, swearing that he must keep it specially chilled for them. They were right. There was a thermoelectric cooling plate in the case. It gave them something to think about, Livermore believed. "Hmmrr…" he said, frowning, the earpieces in his ears, hearing nothing. He had plugged the stethoscope with wax year earlier. The systolic, diastolic murmurs disturbed his concentration; he heard enough of that from his own chest. Everything was in records in any case, since the analysis machines did a far better job than he could ever do. He flipped through the sheets and graphs.
"Button your shirt, sit down, take two of these right now. Just the thing for this condition."
He shook the large red sugar pills from the jar in his desk drawer and pointed to the plastic cup and water carafe. Grazer reached for them eagerly: this was real medicine. Livermore found the most recent X rays and snapped them into the viewer. Lovely. The new kidney was growing, as sweetly formed as a little bean. Tiny now beside its elderly brother, but in a year's time they would be identical. Science conquereth all, or at least almost all; he slammed the file on the table. It had been a difficult morning, and even his afternoon surgery was not as relaxing as it usually was. The old folks, the AKs, his peer group, they appreciated each other. Very early in his career he had taken his M.D., that was all that they knew, and he sometimes wondered if they connected him at all with the Dr. Rex Livermore in charge of the ectogenetic program. If they had ever heard of the program.
"I'm sure glad for the pills, Doc. I don't like those shots no more. But my bowels—"
"Goddamn and blast your bowels. They're as old as my bowels and in just as good shape. You're just bored, that's your trouble."
Grazer nodded approvingly at the insults — a touch of interest in an otherwise sterile existence. "Bored's the very word, Doc. The hours I spend on the pot—"
"What did you do before you retired?"
"That was a real long time ago."
"Not so long that you can't remember, and if you can't, why then you're just too old to waste food and space on, and we'll hook that old brain out and put it in a bottle with a label saying senile brain on it."
