St. Mawr by D. H. Lawrence:
It seemed as if the whole Park, that morning, were in a state of nervous tension. Perhaps there was thunder in the air. But St. Mawr kept on dancing and pulling at the bit, and wheeling sideways up against the railing, to the terror of the children and the onlookers, who squealed and jumped back suddenly, sending the nerves of the stallion into a rush like rockets. He reared and fought as Rico pulled him round.
Then he went on: dancing, pulling, springily progressing sideways, possessed with all the demons of perversity. Poor Rico's face grew longer and angrier. A fury rose in him, which he could hardly control. He hated his horse, and viciously tried to force him to a quiet, straight trot. Up went St. Mawr on his hind legs, to the terror of the Row. He got the bit in his teeth, and began to fight.
