Engraving depicting a milking shed at Laycock's Dairy, Highbury, which supplied a large area of London with fresh milk. There were milking's at 3 am and 12 noon, and the majority of milkmaids were Welsh. After the outbreak of "Cattle Plague" (probably Rinderpest) in London in 1865 the practice of keeping dairy cows in the metropolis was stopped and the milk was transported in from the countryside by rail and road. Dated 19th century
