This is a pub with a typical name. Whatever else pubs are, they are definitely not "bars" in the American sense of the word. They were originally call "ale houses" and were the place bachelor farm workers would go for their evening meal (paid for by the farmer) followed by conversation, games and good fellowship until it was time to go to bed. Marriage was only possible for a worker who stood to inherit a house or who became indispensable to the landowner and had a cottage made available to him. This economic fact of life meant that the majority of manual labourers would never have a wife and family, their only companionship being found round the fire in their local pub.
   These men were gifted craftsmen who could turn their hands to any agricultural tasks that needed to be performed as dictated by the seasons and were justifiably proud of their many talents. But reading and writing would not be amongst their accomplishments. The moneyed classes had a horror of education and believed that learning amongst the masses would lead to a bloody revolution, with the old order turned on its head. Hence, most menial workers could not even write their name, let alone read the name of an ale house, so the custom became to have pictures of instantly recognized items by which that particular place was known. Or they might be named after people in the village: so here we have Derby Arms, after Thomas Derby.
