An English factory was established here in 1758, but with-drawn after a few years . There are two old mosques, decorated with the coloured tiles characteristic of Sind . TATTERSALL'S, the London horse auction mart, founded in 1766 by Richard Tattersall (1724-1795), who had been stud groom to the second duke of Kingston . The first premises occupied were near Hyde Park Corner, in what was then the outskirts of London . Two " Subscription rooms " were re-served for members of the Jockey Club, and they became the rendezvous for sporting and betting men . Among the famous dispersal sales conducted by " Old Tatt" were those of the duke of Kingston's stud in 1774 and of the stud of the Prince of Wales (afterwards George IV.) in 1786 . The prince often visited Richard Tattersall, and was joint proprietor with him of the Morning Post for several years . He was succeeded by his son, Edmund Tattersall (1758-181o), who extended the business of the firm to France . The third of the dynasty, Richard Tattersall (1785-1859), the eldest of Edmund's three sons, became head of the firm at his father's death .

He had his grandfather's ability and tact, and was the intimate of the best sporting men of his

time . Another Richard Tattersall (1812-187o), son of the last, then took command of the business . His great-grandfather's 99-year lease having expired, he moved the business to Knightsbridge . Richard was followed by his cousin, Edmund Tattersall (1816-1898), and he by his eldest son, Edmund Somerville Tattersall (b . 1863) . A son of the second Richard Tattersall, George Tattersall (1817-1849), was a well-known sporting artist . In 1836 he compiled a guide to The Lakes of England illustrated with forty-three charming line drawings, and he showed skill as an architect by building the Tattersall stud stables at Willesden . His experience in this and similar undertakings led him to publish Sporting Architecture (1841) . In the same year, under the pseudonym " Wildrake," he published Cracks of the Day, describing and illustrating sixty-five race-horses . He also contributed illustrations to the Hunting Reminiscences of Nimrod (Charles J . Apperley), the Book of Sports (1843), and the New Sporting Almanack .
