Read the excerpt from chapter 10 of Animal Farm.It was just after the sheep had returned, on a pleasant evening when the animals had finished work and were making their way back to the farm buildings, that the terrified neighing of a horse sounded from the yard. Startled, the animals stopped in their tracks. It was Clover's voice. She neighed again, and all the animals broke into a gallop and rushed into the yard. Then they saw what Clover had seen.It was a pig walking on his hind legs.Yes, it was Squealer. A little awkwardly, as though not quite used to supporting his considerable bulk in that position, but with perfect balance, he was strolling across the yard. And a moment later, out from the door of the farmhouse came a long file of pigs, all walking on their hind legs. Some did it better than others, one or two were even a trifle unsteady and looked as though they would have liked the support of a stick, but every one of them made his way right round the yard successfully. And finally there was a tremendous baying of dogs and a shrill crowing from the black cockerel, and out came Napoleon himself, majestically upright, casting haughty glances from side to side, and with his dogs gambolling round him.
