Excerpt: 'Night fell as the coach reached the excise barrier. Beyond, two sentry boxes buried in the snow faced each other. The coachman shouted between his hands. A drowsy voice answered and white cockades began to move in the dark recesses of the boxes. The light of a lamp emerged from the guard's cottage. Behind the gleam a man with a ri?e over his arm strolled towards the vehicle. The high-wheeled travelling coach was painted in two colours: the upper part dark green, the lower, including the wheels, bright yellow. From near the driver's seat small oil lamps shed their light over the horses' backs. The animals steamed in the cold.'
