Arrived at the Place du Tr&ne, Valentine stopped her horses a moment, and addressed her two cavaliers: "I thank you for your escort, gentlemen. But however high may be your rank, I really can not go through Paris looking like a prisoner between two gendarmes! So good-by! I shall see you this evening perhaps, but good-by for the present." They gave her a military salute, and the carriage disappeared in the Faubourg St. Antoine, while the two horsemen followed the line of the quays along the Boulevard Diderot. CHAPTER XXIV THE CHALLENGE That person who, in springtime, between ten o'clock and midday, never has walked beside the bridle-path in the Bois de Boulogne, under the deep shade of the trees, can form no idea of the large number of equestrians that for many years have been devoted to riding along that delightful and picturesque road. To see and to be seen constitutes the principal raison d'etre of this exercise, where the riders traverse the same path going and coming, a man thus being able to meet more than once the fair one whom he seeks, or a lady to encounter several times a cavalier who interests her. On this more and more frequented road, the masculine element displayed different costumes, according to the age and tastes of each rider. The young men appeared in careless array: leggins, short coats, and small caps. The older men, faithful to early traditions, wore long trousers, buttoned-up redingotes, and tall hats, like those worn by their fathers, as shown in the pictures by Alfred de Dreux. For the feminine element the dress is uniform. It consists of a riding- habit of black or dark blue, with bodice and skirt smoothly molded to the form by one of the two celebrated habit-makers, Youss or Creed. The personal presence alone varied, according to the degree of perfection of the model. A cylindrical hat, a little straight or turned-over collar, a cravat tied in a sailor's knot, a gardenia in the buttonhole, long trousers and varnished boots completed the dress of these modern Amazons, who, having nothing in common with the female warriors of ancient times, are not deprived, as were those unfortunates, of any of their feminine charms. The military element is represented by officers of all grades from generals to sub-lieutenants, in morning coats, with breeches and high boots, forbidden under the Second Empire, but the rule at present. At the top of the Pre-Catelan, the path is crossed by the Bagatelle road to the lakes, a point of intersection situated near a glade where the ladies were fond of stopping their carriages to chat with those passing on horseback. A spectator might have fancied himself at the meet of a hunting-party, lacking the whippers-in and the dogs.
