The chief attendant of the three dynamos that buzzed and rattled at Camberwell, and kept the electric railway going, came out of Yorkshire, and his name was James Holroyd. He was a practical electrician, but fond of whisky, a heavy red-haired brute with irregular teeth. He doubted the existence of the deity, but accepted Carnot's cycle, and he had read Shakespeare and found him weak in chemistry. His helper came out of the mysterious East, and his name was Azuma-zi.
