Riding horseback is a favorite pastime. Ladies only ride in the forenoon, as custom prevents them from indulging in the saddle after one o'clock. Gentlemen, however, ride mornings and evening. Among them are to be found the most graceful and daring riders in the world. Their outfits are gorgeous; true Mexican saddle trimmed with gold and silver, graceful flaps of the finest fur on bridles finished with numberless silver chains. The riders are superb in yellow goatskin suits, ornamented with silver horse shoes, whips, spurs, etc., with silver braid on the short coat. A handsome sombrero, finished in silver, with silver monogram of the owner, revolvers, and proud, fiery, high-stepping horse completed the picture. The ladies' habits are similar to those now in the States, except the fine sombrero which replaces the ugly, ungraceful high silk hats. All day Sunday is like a pleasant Fourth of July, but after eight o'clock the carriages become scarcer and scarcer, the people go to the theaters and to their homes, the poor seek a soft flagstone, where they repose for the night, and by nine o'clock the streets make one think of a deserted city. Mexicans do not go half way in the matter of style. At one o'clock Sunday afternoons policemen in fancy uniforms, mounted on handsome horses, equipped with guns and lassoes, ride down the Boulevard. They are stationed in the center of the drive one hundred yards apart, every alternate horse's head in the same direction. There they remain, like statues, the entire afternoon. Sunday is a favorite day for funerals and change of residence. Men with wardrobes, pianos, etc., on their backs are seen trotting up and down the streets like our moving wagons on the first day of April. They mean well by work on Sunday, but it would appear awful to some of our good people at home. There is this advantage, at least: they have something better to do than to congregate in back-door saloons or loaf on the streets. CHAPTER VII. A HORSEBACK RIDE OVER HISTORIC GROUNDS.
