The name of Bank's bay horse. (See Banks and Horse.)
Morocco. Strong ale made from burnt malt, used in the annual feast at Sevenhalls, Westmoreland (the seat of the Hon. Mary Howard), on the opening of Milnthorpe Fair. This liquor is put into a large glass of unique form, and the person whose turn it is to drink is called the “colt.” He is required to stand on one leg, and say “Luck to Sevens as long as Kent flows,” then drain the glass to the bottom, or forfeit one shilling. The act is termed “drinking the constable.” The feast consists of radishes, oaten cake, and butter.
