?A simple demonstration will suffice to answer your question, Miss Welsh,? Wohler-9 replied.
He unclipped a meter-long, chrome-plated crowbar from the side of the lorry and started walking toward the edge that bordered the right side of the opening in the dome's glimmer.
Ariel and Jacob followed him, and as Ariel approached the interior of the dome, getting a little ahead of Wohler-9 in her impetuous fashion, she could see up close the soft blackness of the lining, a blackness that demarcated the end of the ground and the beginning of what seemed open space. Looking down at it sent her into a dizzying subjective vertigo. She seemed to spin in that black space as it drew her down, sucking at her mind.
?Under no circumstances come closer than half a meter, Miss Welsh,? Wohler-9 said as he casually moved his arm in front of her. With that warning she seemed to come to her senses, and she moved back out so that she was facing the edge from a distance of a few meters; her head cleared, and from that position she could now see along both the inside and outside walls.
Wohler-9 then approached the edge of the wall to almost that half-meter limit himself. He stopped then, facing the inner wall, and said; ?And don't become confused. The wall may seem deceptively far away. ?
He took a baseball batter's stance then, and with a lusty swing that brought the crowbar around in a horizontal arc perpendicular to the wall, he struck the edge of the dome with the middle of the crowbar. Without a sound, the edge of the dome, like the edge of a supersharp tool, cut the crowbar neatly in half. The far end of the crowbar sailed off. The near end stayed firmly in Wohler-9's hands as he completed his swing.
Then he casually tossed the remnant toward the inside wall.
Ariel's eyes had naturally followed the flight of the far end of the crowbar until it hit the ground and stopped skidding. She looked back just as Wohler-9 tossed the piece left in his hand toward the interior blackness.
That piece seemed to curve in toward the blackness a fraction of the distance it would have traveled if he had tossed it straight up in the air with the same force, and then it came shooting back out on a parabolic course obviously calculated to hit no one. It landed behind him a distance equal to the distance it would have traveled in front of him if the wall had not been there.
?Now, a second demonstration will point up and clarify the dome's external characteristics,? Wohler-9 said.
He picked up the half-crowbar that had just sailed back out of the blackness, walked over, tossed it into the lorry, and then unclipped two sections of a tubular pole from the side of the vehicle. When he fitted the two sections together, he had a pole about five meters long. From a locker he took a large piece of white cloth that he unfolded and tied to the pole to form a square flag a little less than four meters on a side. With the flagpole in hand, he walked along the outside of the dome until he was three or four meters from the edge of the opening. Ariel followed him.
They were walking along the edge of a deep, shimmering hemispherical pit two kilometers across and a kilometer deep. From that viewpoint there was no evidence of the city that they knew existed inside the shimmer.
?Under no circumstances let any part of your body touch or project into the transparent dome,? Wohler-9 said. ?That part of you would go through and never be the same again. Now observe the flag.?
He pushed the flag through the dome's glimmer. It seemed to disappear.
?Perhaps it appears to be gone,? he said, waving the pole, ?but look carefully at the far side of the pit.?
At first Ariel could see nothing unusual on the other side, but after a moment, after looking more carefully, she finally saw a tiny white flag waving, far away, two kilometers away, on the other side of the pit.
Wohler-9 laid down the pole so that it still projected into the dome. It did not lie flat on the ground. The near end hung suspended, slanting into the dome at the ground. The tiny flag on the other side of the pit had disappeared into the grass.
?Two further observations,? Wohler-9 said, ?for which we'll use the lorry.?
He left the pole projecting into the dome, retrieved the other half of the crowbar from the deep grass, tossed it into the lorry beside the first half, and stepped in to stand at the driver's station. Ariel took a seat immediately behind the golden robot and Jacob stepped up to stand beside Wohler-9, who immediately took off down the west side of the dome, staying well away from the edge of the pit.
They were almost halfway around the dome before Wohler-9 spoke again.
?We should be coming to it now,? he said.
And then Ariel saw the white flag lying in the grass with the pole sticking out of the dome a few centimeters above the ground.
Wohler-9 stopped the lorry.
?You don't need to get out.?
He stepped down from the lorry, picked up the pole carefully, as though it were a fragile memento, walked back, and offered the flag end to Ariel.
?Take hold of the end,? he said.
When she did, he moved his end as though to bend it in her grip, and it snapped in two.
?Passing through the dome distorts the crystal structure, setting up fault lines with very little strength. Now one last observation, this time inside the dome.?
He drove back the way they had come and then drove through the opening, close to the right side. The traffic pouring out of the dome gave way smoothly, shifting to its right to accommodate the lorry, as though a computer were directing all the traffic?which it was, of course: the city central computer.
?We'll take the perimeter route to avoid bucking the traffic coming down Main Street,? Wohler-9 said, ?even though it will be a little longer this way, half-pi-times longer.?
Wohler-9 drove rapidly to a point half-way around the perimeter of the dome. He stopped at the same wide street: Main Street, which approached the dome as close as any. Ariel looked back down the street and saw the Compass Tower framed in the opening of the dome.
Wohler-9 led them now to the dome wall opposite the end of the street and handed Ariel a pair of binoculars as he pointed to a small bright object in the soft darkness of the inner wall.
Ariel put the binoculars to her eyes, and with the focus wheel at the infinite setting, she could just barely make out a shape that had the appearance of a small two-man flier headed toward them with its landing lights on.
?This is our final test of the dome, which we began earlier this afternoon,? Wohler-9 said. ?Right now the flier is held by the gravity of the black concavity at a virtual distance of four kilometers. It is headed toward us, but held motionless by the black concavity with the flier's impulse engines throttled back to 75% capacity, equivalent to an acceleration of ten gees. We plan to bring it in now. Its fuel is almost depleted.?
Ariel had a hard time taking the binoculars away from her eyes. She turned to hand them to Jacob.
?Here, I want you to record this,? she said. ?I want you as a witness. Derec ' s not apt to believe any of this. ?
?Thank you, Miss Ariel,? Jacob said, ?but with my 50-power binocular vision I have already recorded the unusual operation of this flier.?
Ariel was tired. It had been a long day already. Altogether too much for one day. Too much sensory stimulation, too many strange ideas, too much emotion. She missed Derec and felt inadequate to the challenge presented by this alien world.
?Unless you have further exhibits and demonstrations, Wohler,? Ariel said, ?I would like to shower and freshen up. Later, after some dinner, you can give me a detailed report.?
?I have just ordered in the flier, Miss Welsh,? Wohler-9 said. ?We shall now proceed immediately to your apartment.?
As they drove down the broad street toward the Compass Tower, the faint sound of the flier grew louder. Ariel turned to watch its lights growing brighter now in the soft darkness surrounding the city. She had a hard time taking in everything she had seen in the short time she had known Wohler-9.
Then she could see the flier growing larger with her naked eye, until it came hurtling out of the wall and screamed by overhead, spiraling up over the Compass Tower and out the opening in the dome.

THE LAWS OF ROBOTICS

1. A robot may not injure a human being, or, through inaction, allow a human being to come to harm.
2. A robot must obey the orders given it by human beings except where such orders would conflict with the First Law.
