Loudons looked and shrugged, then looked again and pointed.

"There's a bear. Just ducked into that church or movie theater or whatever. I wonder what he thinks we are."

Altamont puffed slowly at his pipe, "I wonder if we're going to find anything at all in Pittsburgh."

"You mean people, as distinct from those biped beasts we've found so far? I doubt it," Loudons replied, finishing his caffchoc and wiping his mustache on the back of his hand. "I think the whole eastern half of the country is nothing but forest like this, and the highest type of life is just about three cuts below Homo Neanderthalensis, almost impossible to contact, and even more impossible to educate."

"I wasn't thinking about that; I've just about given up hope of finding anybody or even a reasonably high level of barbarism," Altamont said. "I was thinking about that cache of microfilmed books that was buried at the Carnegie Library."

"If it was buried," Loudons qualified. "All we have is that article in that two-century-old copy of Time about how the people at the library had constructed the crypt and were beginning the microfilming. We don't know if they ever had a chance to get it finished, before the rockets started landing."

They passed over a dam of flotsam that had banked up at a wrecked bridge and accumulated enough mass to resist the periodic floods that had kept the river usually clear. Three human figures fled across a sand-flat at one end of it and disappeared into the woods; two of them carried spears tipped with something that sparkled in the sunlight, probably shards of glass.

"You know, Monty, I get nightmares, sometimes, about what things must be like in Europe," Loudons said.

Five or six wild cows went crashing through the brush below. Altamont nodded when he saw them.

"Maybe tomorrow, we'll let down and shoot a cow," he said. "I was looking in the freezer-locker; the fresh meat's getting a little low. Or a wild pig, if we find a good stand of oak trees. I could enjoy what you'd do with some acorn-fed pork. Finished?" he asked Loudons. "Take over, then; I'll go back and wash the dishes."
