This photograph was taken at the Royal Mews, probably in the 1960s, and it shows the chalkboard that notes the specialised diets required by every carriage horse. A member of Royal Mews staff can be seen holding the feed bucket for the horse, Waterford. The Queen names every horse in the Royal Mews, and some on this list reflect places and people visited during state visits – Cape Town, Pretoria and Eisenhower, for example.

Two of the horses toward the bottom of the list include the word Mulgrave in their names, which was the prefix for a renowned line of Cleveland Bay horses. Queen Elizabeth II purchased the stallion, Mulgrave Supreme, in the 1960s, from which further foals were bred, is widely credited with saving the English native breed, which today remains endangered with a population of three hundred horses. The Cleveland Bays can often be seen at the Royal Mews, being schooled in the Riding School, trained on the local roads near Buckingham Palace, or harnessed to the twice-daily messenger Brougham, which takes post from Buckingham Palace to St. James’s Palace.
