And yet it wasn't all foolishness. Close-order drill and 2500-calorie-a-day diet began to put fat and flesh and muscle on Tropile's body, and something other than that on his mind. He had not lost the edge of his acquisitiveness, his drive--his whatever it was that made the difference between Wolf and sheep. But he had gained something. Happiness? Well, if "happiness" is a sense of purpose, and a hope that the purpose can be accomplished, then happiness. It was a feeling that had never existed in his life before. Always it had been the glandular compulsion to gain an advantage, and that was gone, or anyway almost gone, because it was permitted in the society in which he now lived. Glenn Tropile sang as he putt-putted in his tractor, plowing the thawing Jersey fields. Still, a faint doubt remained. Squads right against the Pyramids? Stiffly, Tropile stopped the tractor, slowed the diesel to a steady _thrum_ and got off. It was hot--being midsummer of the five-year calendar the Pyramids had imposed. It was time for rest and maybe something to eat. He sat in the shade of a tree, as farmers always have done, and opened his sandwiches. He was only a mile or so from Princeton, but he might as well have been in Limbo; there was no sign of any living human but himself. The northering sheep didn't come near Princeton--it "happened" that way, on purpose. He caught a glimpse of something moving, but when he stood up for a better look into the woods on the other side of the field, it was gone. Wolf? _Real_ Wolf, that is? It could have been a bear, for that matter--there was talk of wolves and bears around Princeton; and although Tropile knew that much of the talk was assiduously encouraged by men like Haendl, he also knew that some of it was true. As long as he was up, he gathered straw from the litter of last "year's" head-high grass, gathered sticks under the trees, built a small fire and put water on to boil for coffee. Then he sat back and ate his sandwiches, thinking. Maybe it was a promotion, going from the nursery school to labor in the fields. Or maybe it wasn't. Haendl had promised him a place in the expedition that would--maybe--discover something new and great and helpful about the Pyramids. And that might still come to pass, because the expedition was far from ready to leave. Tropile munched his sandwiches thoughtfully. Now _why_ was the expedition so far from ready to leave? It was absolutely essential to get there in the warmest weather possible--otherwise Mt. Everest was unclimbable. Generations of alpinists had proved that. That warmest weather was rapidly going by. And _why_ were Haendl and the Wolf colony so insistent on building tanks, arming themselves with rifles, organizing in companies and squads? The H-bomb hadn't flustered the Pyramid. What lesser weapon could?
