ground, and it was like no robot he had ever before seen.
Once the initial surprise had worn off, he felt himself the complete master of the situation. All his life he had given orders to machines, and the fact that this one was unfamiliar was of no importance. For that matter, he had never seen more than a few per cent of the robqts that provided hip daily needs in Diaspar.
"Can you speak?" he asked.
There was silence.
"Is anyone controlling you?"
Still silence.
"Go away. Come here. Rise. Fall."
None of the conventional control thoughts produced any effect. The machine remained contemptuously inactive. That suggested two possibilities. It was either too unintelligent to understand lion or it was very intelligent indeed, with its own powers of choice and volition. In that case, he must treat it as an equal. Even then he might underestimate it, but it would bear him no resentment, for conceit was not a vice from which robots often suffered.
Hilvar could not help laughing at Alvin's obvious discomfiture. He was just about to suggest that he should take over the task of communicating, when the words died on his lips The stillness of Shalmirane was shattered by an ominous and utterly unmistakable sound-the gurgling splash of a very large body emerging from water.
It was the second time since he had left Diaspar that Alvin wished he were at home. Then he remembered that this was not the spirit in which to meet adventure, and he began toe walk slowly but deliberately toward the lake.
The creature now emerging from the dark water seemed a monstrous parody, in living matter, of the robot that was still subjecting them to its silent scrutiny. That same equilateral arrangement of eyes could be no coincidence; even the pattern of tentacles and little jointed limbs had been roughly reproduced. Beyond that, however, the resemblance ceased. The robot did not possess-it oviously did not require the fringe of delicate, feathery palps which beat the water with a steady rhythm, the stubby multiple legs on which the beast was humping itself ashore, or the ventilating inlets, if that was what they were, which now wheezed fitfully in the thin air.
Most of the creature's body remained in the water; only the first ten feet reared itself into what was clearly an alien element. The entire beast was about fifty feet long, and even anyone with no knowledge of biology would have realized that there was something altogether wrong about it. It had as extraordinary air of improvisation and careless design, as if its components had been manufactured without much forethought and thrown roughly together when the need arose.
Despite its size and their initial doubts, neither Alvin nor Hilvar felt the slightest nervousness once they had had a clear look at the dweller in the lake. There was an engaging clumsiness about the creature which made it quite impossible to regard it as a serious menace, even if there was any reason to suppose it might be dangerous. The human race had long ago overcome its childhood terror of the merely alien in appearance. That was a fear which could no longer survive after the first contact with friendly extraterrestrial races.
"Let me deal with this," said Hilvar quietly. "I'm used to handling animals."
"But this isn't an animal," whispered Alvin in return. "I'm sure it's intelligent, and owns that robot."
"The robot may own it. In any case, its mentality must be very strange. I can still detect no sign of thought. Hello what's happening?"
The monster had not moved from its half-raised position at the water's edge, which it seemed to be maintaining with considerable effort. But a semitransparent membrane had begun to form at the center of the triangle of eyes-a membrane that pulsed and quivered and presently started to emit audible sounds. They were low-pitched, resonant boomings which created no intelligible words, though it was obvious that the creature was trying to speak to them.
It was painful to watch this desperate attempt at communication. For several minutes the creature struggled in vain; then, quite suddenly, it seemed to realize that it had made a mistake. The throbbing membrane contracted in size, and the sounds it emitted rose several octaves in frequency until they entered the spectrum of normal speech. Recognizable words began to form though they were still interspersed with gibberish. It was as if the creature was remembering a vocabulary it had known long ago but had had no occasion to use for many years.
Hilvar tried to give what assistance
