Horses And Orchids: Society Turns Out for Horse Show Diamonds and tails, sleek horses and trim riders - they all add up to the 79th National Horse Show - the most glittering pageant of the New York fall social season. Jacks or Better and his rider, Ben O'Meara, take the Imperial Puissance, another in their long string of victories. Very well-to-do, well dressed people seated in stands.
