There were several pairs of waldoes growing out of a steel ring which surrounded the working space. Two pairs, mere monkey fists in size, were equipped with extensors. It had been one of these which had shot out to grab Baldur by his collar. There were waldoes rigged near the spherical wall, too, including one pair so huge that Stevens could not conceive of a use for it. Extended, each hand spread quite six feet from little finger tip to thumb tip

There were books in plenty on the wall, but no bookshelves. They seemed to grow from the wall like so many cabbages

It puzzled Stevens momentarily, but he inferred - correctly it turned out later - that a small magnet fastened to the binding did the trick

The arrangement of lighting was novel, complex, automatic, and convenient for Waldo. But it was not so convenient for anyone else in the room. The lighting was, of course, indirect; but, furthermore, it was subtly controlled, so that none of the lighting came from the direction in which Waldo's head was turned. There was no glare - for Waldo. Since the lights be­hind his head burned brightly in order to provide more illu­mination for whatever he happened to be looking at, there was glare aplenty for anyone else. An electric eye circuit, obviously. Stevens found himself wondering just how simple such a cir­cuit could be made

Grimes complained about it. ‘Damn it, Waldo; get those lights under control. You'll give us headaches.

‘Sorry, Uncle Gus.' He withdrew his right hand from its gauntlet and placed his fingers over one of the control panels. The glare stopped. Light now came from whatever direction none of them happened to be looking, and much more brightly, since the area source of illumination was much reduced. Lights rippled across the walls in pleasant patterns. Stevens tried to follow the ripples, a difficult matter, since the setup was made not to be seen. He found that he could do so by rolling his eyes without moving his head. It was movement of the head which controlled the lights; movement of an eyeball was a little too much for it

‘Well, Mr Stevens, do you find my house interesting?' Waldo was smiling at him with faint superciliousness

‘Oh - quite! Quite! I believe that it is the most remark­able place I have ever been in.

‘And what do you find remarkable about it?

‘Well - the lack of definite orientation, I believe. That and the remarkable mechanical novelties. I suppose I am a bit of a groundlubber, but I keep expecting a floor underfoot and a ceiling overhead.

‘Mere matters of functional designs, Mr Stevens; the con­ditions under which I live are unique; therefore, my house is unique. The novelty you speak of consists mainly in the elimination of unnecessary parts and the addition of new con­veniences

‘To tell the truth, the most interesting thing I have seen yet is not a part of the house at all.

‘Really? What is it, pray?

‘Your dog, Baldur.' The dog looked around at the mention of his name. ‘I've never before met a dog who could handle himself in free flight.

Waldo smiled; for the first time his smile seemed gentle and warm. ‘Yes, Baldur is quite an acrobat. He's been at it since he was a puppy.' He reached out and roughed the dog's cars, showing momentarily his extreme weakness, for the gesture had none of the strength appropriate to the size of the brute. The finger motions were flaccid, barely sufficient to disturb the coarse fur and to displace the great ears. But he seemed un­aware, or unconcerned, by the disclosure. Turning back to Stevens, he added, ‘But if Baldur amuses you, you must see Ariel.

‘Ariel?

Instead of replying, Waldo touched the keyboard of the voder, producing a musical whistling pattern of three notes. There was a rustling near the wall of the room ‘above' them; a tiny yellow shape shot towards them - a canary. It sailed through the air with wings folded, bullet fashion. A foot or so away from Waldo it spread its wings, cupping the air, beat them a few times with tail down and spread, and came to a dead stop, hovering in the air with folded wings. Not quite a dead stop, perhaps, for it drifted slowly, came within an inch of Waldo's shoulder, let down its landing gear, and dug its claws into his singlet

Waldo reached up and stroked it with a fingertip. It preened

‘No earth-hatched bird can learn to fly in that fashion,' he stated. ‘I know. I lost half a dozen before I was sure that they were incapable of making the readjustment. Too much thalamus.

‘What happens to them?

‘In a man you would call it acute anxiety psychosis. They try to fly; their own prime skill leads them to disaster. Natur­ally, everything they do is wrong and they don't understand it

Presently they quit trying; a little later they die. Of a broken heart, one might say, poetically.' He smiled thinly. ‘But Ariel is a genius among birds. He came here as an egg; he invented, unassisted, a whole new school of flying.' He reached up a fin­ger, offering the bird a new perch, which it accepted

‘That's enough, Ariel. Fly away home.

The bird started the ‘Bell Song' from Lakmé

He shook it gently. ‘No, Ariel. Go to bed.

The canary lifted its feet clear of the finger, floated for an instant, then beat its wings savagely for a second or two to set course and pick up speed, and bulleted away whence he bad come, wings folded, feet streamlined under

‘Jimmie's got something he wants to talk with you about,' Grimes commenced

‘Delighted,' Waldo answered lazily, ‘but shan't we dine first? Have you an appetite, sir?

Waldo full, Stevens decided, might be easier to cope with than Waldo empty. Besides, his own midsection informed him that wrestling with a calorie or two might be pleasant. ‘Yes, I have.

‘Excellent.' They were served

Stevens was never able to decide whether Waldo had pre­pared the meal by means of his many namesakes, or whether servants somewhere out of sight had done the actual work. Modern food-preparation methods being what they were, Waldo could have done it alone; he, Stevens, batched it with no difficulty, and so did Gus. But he made a mental note to ask Doc Grimes at the first opportunity what resident staff, if any, Waldo employed. He never remembered to do so

The dinner arrived in a small food chest, propelled to their midst at the end of a long, telescoping, pneumatic tube. It stopped with a soft sigh and held its position. Stevens paid little attention to the food itself - it was adequate and tasty, he knew - for his attention was held by the dishes and serving methods. Waldo let his own steak float in front of him, cut bites from it with curved surgical shears, and conveyed them to his mouth by means of dainty tongs. He made hard work of chewing

‘You can't get good steaks any more,' he remarked. ‘This one is tough. God knows I pay enough - and complain enough.

Stevens did not answer. He thought his own steak had been tenderized too much; it almost fell apart. He was managing it with knife and fork, but the knife was superfluous. It appeared that Waldo did not expect his guests to make use of his own admittedly superior methods and utensils. Stevens ate from a platter clamped to his thighs, making a lap for it after Grimes's example by squatting in mid air. The platter itself had been thoughtfully provided with sharp little prongs on its service side

Liquids were served in small flexible skins, equipped with nipples. Think of a baby's plastic nursing bottle

The food chest took the utensils away with a dolorous in­sufflation. ‘Will you smoke, sir?

‘Thank you.' He saw what a weight-free ashtray necessarily should be: a long tube with a bell-shaped receptacle on its end. A slight suction in the tube, and ashes knocked into the bell were swept away, out of sight and mind
