RENDEZVOUS AT LONGCHAMP

The Prix De L'Arc De Triomphe is the Continent's richest and most celebrated horse race, and its running traditionally signals the beginning of the Paris winter social season. The international set swarms into Paris in the first week of October for a bout of prerace receptions, dinner parties and excursions to the chestnut-wooded Long-champ course, which observes its 100th anniversary this year. One of the most notable social events is the dinner which Marcel Boussac, textile tycoon and horse owner, tenders on the top floor of Maxim's (see page 30), featuring a savory concoction of lobster cooked in whisky. Boussac invites every owner of an Arc de Triomphe entry to his affair, but adds a whimsical condition: if a horse is scratched, the owner is summarily disinvited. The race was won by Oroso, a 52-1 shot, from 23 rivals, including C. V. Whitney's Career Boy, who finished 18th. Oroso's owner, Raoul Mayer, promptly accepted an invitation to run his colt in the Washington International at Laurel next month.
