Huyghens threw a switch. He began to turn the knob which controlled the knob of his makeshift-modified receiver.
"Why," he said amusedly, "when I was young the people around me tried to make me into a conscientious citizen and a loyal employee and a well-adjusted personality. They tried to make me into a highly intelligent rational animal and nothing more. The difference between us, Roane, is that I found it out. Naturally, I rev—"
He stopped short. Faint, crackling, crisp frying sounds came from the speaker of the space phone now modified to receive what once were called short waves.
Huyghens listened. He cocked his head intently. He turned the knob very, very slowly. Then Roane made an arrested gesture, to call attention to something in the sibilant sound. Huyghens nodded. He turned the knob again, with infinitesimal increments.
Out of the background noise came a patterned mutter. As Huyghens shifted the tuning, it grew louder. It reached a volume where it was unmistakable. It was a sequence of sounds like discordant buzzing. There were three half-second buzzings with half-second pauses between. A two-second pause. Three full-second buzzings with half-second pauses between. Another two-second pause and three half-second buzzings, again. Then silence for five seconds. Then the pattern repeated.
"The devil!" said Huyghens. "That's a human signal! Mechanically made, too! In fact, it used to be a standard distress-call. It was termed an SOS, though I've no idea what that meant. Anyhow, somebody must have read old-fashioned novels, some time, to know about it. And so someone is still alive over at your licensed, but now smashed-up, robot colony. And they're asking for help. I'd say they're likely to need it."
He looked at Roane.
"The intelligent thing to do is sit back and wait for a ship—either of my friends or yours. A ship can help survivors or castaways much better than we can. A ship can even find them more easily. But maybe time is important to the poor devils! So I'm going to take the bears and see if I can reach them. You can wait here, if you like. What say? Travel on Loren Two isn't a picnic! I'll be fighting nearly every foot of the way. There's plenty of 'inimical animal life' here!"
Roane snapped angrily:
"Don't be a fool! Of course I'm coming! What do you take me for? And two of us should have four times the chance of one!"
