He slipped a torn handkerchief from his pocket, and with the buckle of his belt, loosened some of the crystal chips.
"I don't know whether I can ever analyze these," he said to Slag, "but I'll take them along, anyhow."
Slag stood at one of the tall, arched windows, red head gleaming in the sun. He was making guttural noises in his throat, and he kept lifting and dropping his big warclub. Thor stepped to his side and looked into the streets.
Men were walking stealthily along the cobblestones.
Thor blinked and rubbed his eyes. He was staring down at men clad in chain-mail armour, men in fur skins, men in suits of the same cut as he wore. There was a huge creature that Thor would have sworn was an ape, except for the two tusks depending from its lips, and its erect, intelligent bearing. There was a four-legged being, and something that had two heads. There was—
"They are men, Slag. Real men. Not androids!"
He felt a warm delight in him, a welling of friendliness inspired by the weeks of wandering on the red, lonely grasslands. He lifted an arm and opened his lips to shout. A mental censor made him close his mouth. It would be better to wait, to see what manner of men these were who stalked the empty streets of a deserted city, before showing himself.
Thor vaulted over the stone sill, calling to Slag to follow. Side by side they crept after the group.
They went deeper into the heart of the city. By twisted alleys the stalkers went, and their furtive tread and cautious glances told Thor that they were in hostile territory. Where a building cast gloomy shadows, he ran nearer, until he could distinguish voices.
