“ And he could say one other thing about it, Dowland added mentally. The same ponderous entity could knock out a man for hours, without apparently injuring him, or leaving any sign of how he had been struck down.
The last sounded more like a machine again; a machine which was armed in some mysterious manner. When his shot had flushed up the big flying creature during the night, he'd almost been convinced that some monster out of Terra's distant past was there on the mesa. ”

“ Dowland asked, "have your uncles been doing here?"
"Building a machine that will enable them to move back through time."
"With the help of Ym-400?"
"Yes."
Dowland stared at her thoughtfully, feeling a little chilled. She believed it, of course; she was incapable of lying now. But he didn't believe it. He'd heard that some Overgovernment scientists considered time-travel to be possible. It was a concept that simply had no reality for him.
But he thought of the rumors about YM—and of Miguel found lying inexplicably outside the laboratory building. ”

“ Dowland rubbed the side of his nose, scowling slightly. If the ranch really was deserted, it would be best to leave it alone for the time being and search elsewhere for Trelawney. To go down uninvited in the absence of the owner would be as much out of character for an experienced visitor on Terra as for a Freeholder. If observed at it—a remote possibility perhaps in this area, but the possibility was there—he could offer the excuse of a suspicion of engine trouble in the grid-car. ”

“ But the Freeholders feared—perhaps with justification, so far as Dowland could tell—that political pressures would mount with each increase in excess population and eventually lead to such measures. Many of them, probably the majority, led by Anthony Brand Carter—Firebrand Carter, head of the largest and wealthiest of the Families—believed that the only safe solution was to arm the planet. They wanted heavy weapons, and enough of them: the right to build them, to man them and, if necessary, to use them to beat off encroaching groups. ”

“ Instantly, something slammed him sideways against the console, sent him staggering along it, and over the low railing at the end of the platform. The floor seemed to be shuddering as he struck it, and then to tilt slowly. Dowland rolled over, came up on hands and knees, facing back toward the platform. Daylight blazed again in the building behind him, and the roar of a river that rolled through another time filled his ears. He got to his feet, plunged back toward the whipping rope above the platform. ”

“ In the next instant, without the slightest preliminary warning, every instrument in the panel before Dowland went dead. Then the grid-car began to drop like a stone.
The world-wide gravity grid was Terra's general power source. It had been an idiotically expensive installation; actually, no other planet could have afforded it at present. Once installed, it was drawn on for idiotically minor services. There weren't enough human beings on Terra to begin to make a significant use of the grid. ”

“ By the time we catch up with our friends, we expect the sacrifice will have been—in one way or another—to our advantage."
"And suppose," said Fry, "that their secret experiments with Ym-400 result in turning another planet into an asteroid cloud?"
"That's an extreme possibility," Camhorn said, "though it exists. The point is that it exists now whatever we choose to do about it. We can only attempt to minimize the risks." ”

“ The first specimen of humanity the aliens encountered alive was Paul Trelawney. High genius level, man! It would take that level to nullify our I.Q. tests in the manner he and his half-brother did. When those creatures were prowling around on the mesa, they were looking for that kind of mentality. Dowland's above average, far from stupid. As you say, you like his theories. But he's no Trelawney. Unquestionably, the aliens in each case regarded him as some kind of clever domestic animal. The only reason he's alive is that they weren't taking him seriously. ”

“ He was a stocky man in his early thirties, strongly built, dressed in hunting clothes. The packed equipment in the grid-car, except for a few special items, was that of a collector of live game, the role regularly assumed by Dowland when at work on the planet. The Freeholder Families traditionally resented any indication of Overgovernment authority on Terra, and would have been singularly uncordial to a Solar City police detective here, regardless of the nature of his mission. But the export of surplus native fauna was one of the forms of trade toward which they were tolerant. ”

“ The danger was more obviously there in the boar. The brute's eight hundred or so pounds of weight above that of the average of his prospective harem would not be significant when pitted against an opponent as physically inferior as a human being. His attitude might. The sows filed out into the corral after they had eaten what the feeding machine had thrown into them. The boar remained, watching Dowland on the gangway above him from the corner of one eye. The eye reflected no gratitude for the feeding. ”

“ The Freeholders entertained an open grudge against the Overgovernment, which had restricted their nominally unclouded title to the planet by somewhat underhanded legal means, when the principle of the Freehold Worlds was laid down. Essentially, the Families became the very highly paid caretakers of Terra. To Dowland, raised in the crowded tunnels of the system of artificial giant asteroids known as Solar City, the conservation of the natural resources of a living world looked like a good idea. The Terran Families were interested in conservation, but on their terms and under their control. ”

“ A man exhausted and not sure of where he was on the big table-land, an injured man—or perhaps one weakened by radiation sickness—such a man would fire a gun in the night to draw attention to himself. To get help.
Minutes later, Dowland was headed in the direction from which the shots had come, carrying one of his own rifles, along with the police gun. It was very unlikely he could get close enough to Trelawney—if it was Trelawney—to be heard approaching; but once he reached the general area of the shots, he would fire the rifle, and wait for a response. ”

“ Terra's grid-power had returned to Lion Mesa.
A week later, Lieutenant Frank Dowland was shown into the office of the chief of the Solar Police Authority. The chief introduced him to the two other men there, who were left unidentified, and told him to be seated.
"Lieutenant," he said, "these gentlemen have a few questions to ask you. You can speak as openly to them as you would to me."
Dowland nodded. He had recognized one of the gentlemen immediately—Howard Camhorn, the Coordinator of Research. Reputedly one of the sharpest minds in the Overgovernment's top echelons. ”

“ Miguel, Paul's senior by almost twenty years, now in his early fifties, had also taken an interest in physics, attending an Overgovernment university a quarter of a century earlier. Miguel's studies terminated before he obtained a degree, as a result of a difference of opinion with the president of the university, whom he challenged to a duel. The records of both brothers indicated, in Dowland's opinion, more than a trace of the megalomania not too uncommon among men with excessive wealth and no real claim to distinction. ”

“ Dowland fitted the key into the central depression in the door, pressed down, felt the key snap into position with a sharp twisting motion of its own, released his pressure on it. An instant later, the key popped back out into his hand. He tossed it back to Trelawney, who caught it left-handed and threw it over his head in Jill's direction. The disk thudded heavily into the grass ten feet from her. The girl walked over, picked it up, and slid it into one of her suit pockets. ”

“ No point in considering it—he couldn't get into the laboratory. An hour and a half had gone to no purpose. Hunting for the key had looked like a good gamble, the quickest and therefore least dangerous method of solving the whole awesome problem. But it hadn't worked out; and what was left was to work down the side of Lion Mesa, and start hiking out across the desert. With luck, he'd find the communicator start picking up grid-power again around dawn—if the YM didn't cut loose with further unpredictable and much more disastrous "phenomena" before then. ”

“ No, the machine was searching for Terra as Terra is known to have been in the latter part of the Pleistocene period. The Trelawneys had provided something like a thousand very specific factors to direct and confine that search. Time is impenetrable, so the machine had to find that particular pattern of factors in space, and did. The aliens—again as Lieutenant Dowland theorized—then moved through Riemann space to the planet where the YM thrust was manifesting itself so violently. ”

“ In spite of the binoculars, Dowland was immediately sure of the woman's identity—having, in the past few days, studied a number of pictures of her. She was Jill Trelawney, the youngest of the three surviving members of the Trelawney Freeholders. Miguel and Paul were her uncles—and if she was here, one or the other of the men must certainly be here also.
It was obvious that she was signaling to the car. Dowland glanced at the communicator in the panel before him, saw it was turned on but registering no local calls. ”

“ Jill looked doubtful. "There's no easy way down off the mesa even in daylight. And at night it would be worse."
Dowland said, "That part of it won't be too much of a problem. I brought mountaineering equipment along this trip—planned to pick up a Marco Polo ram and a few ewes—piton gun, clamp pitons, half-mile of magnetic rope; the works. Question is, how much good will it do? I've got a camp communicator, but it's grid-powered, and we don't know how far the power failure extends around here at ground level. Is there anyone down in the plain we could contact? They might have horses." ”

“ But duplicates of their machine in the laboratory are concealed about the planet, waiting to be put into action by other teams of Freeholder scientists. You see? The tests will be continued until any problems connected with shifting back through time are recognized and overcome."
Dowland said, "Then why is the entire haul of YM stacked away in the laboratory here?"
"Because that's where it's to be used at present. You still don't understand the extent of this operation, Dowland. If we need more of the Overgovernment's YM, we'll simply take it. It can be done at any time. ”

“ Trelawney remarked, "we may be able to take things a little easier."
"What's the quantity you're using in there?"
"No real reason I should tell you that, is there? But I will. The sixty-eight kilograms the Overgovernment's been grieving about are under the machine platform. We're using all of it." He grinned briefly, perhaps at Dowland's expression. "The type of job we had in mind required quantities in that class. Now, about yourself. We're not murderers. Jill tells me you can't be bribed—all right. ”

“ I think these aliens can control the minds of other beings, but can't control them through the interference set up by something like our AR fields. Paul Trelawney appeared in the other time period almost in their laps. He had a rifle strapped over his back, but presumably they caught him before he had a chance to use it. They would have examined him and the equipment he was carrying, and when they took off his radiation suit, they would have discovered he belonged to a race which they could control mentally. ”
