The porous plastron is not in favor this year, but many horses who interfere are wearing life-preservers over the fetlock, and sometimes a small chest-protector of russet leather over the joint, according to the taste of the wearer. Polka-dot or half-mourning dogs are much affected by people who are beginning to get the upper hand of their grief. Much taste is shown in the selection of dogs for the coming season, and many owners chain their coachman to the dog, so that if any one were to come and try to abduct the dog the coachman could bite him and drive him away. A good coachman to take care of a watch-dog is almost invaluable. A custom of taking the butler along in the seat with the coachman is growing in favor for two reasons: First, it shows that you have a butler, and, second, you know that while he is out with you he is not putting paste in the place of your diamonds at home. So I had almost said that it paste to do this. The automatic or jointless footman is still popular, and a young man who has a good turning-lathe leg and an air of impenetrable gloom can get a job most any time. Many New York gentlemen who are fond of driving take their grooms out to Central Park every afternoon for an airing. This is a wise provision, for those who have associated much with grooms will agree with me that a little airing now and then is just what they need. There ought to be a book of park etiquette printed soon, however, for the guidance of its patrons. In the first place, it should be considered. Autre for a gentleman to hire a coupe by the hour in order to recover from alcoholic prostration, and then sleep up and down the drive with his feet out the window. It is not respectful, and besides that the blood is liable to all rush to his head. Drunken cab-drivers, too, should not be permitted to drive in the park, for only a little while ago one of them is said to have fallen from his high perch and injured his crest. A park policeman should be specially detailed as a breath tester to stand at each entrance and smell the breath of all drivers and other patrons of the park. Let us enforce the law. But the most curious feature about the exhibition afternoon spin in the Park is the great prevalence of mourning symbols. Almost, if not quite, one-third of the carriages one meets is decorated with black in every possible way, till sometimes it looks like a runaway funeral procession. Why people should come to Central Park to advertise their woe by means of long black mourning tassels at their horses' heads and a draped driver with broad bands of bombazine concealing the russet tops of his boots, sometimes dressed in black throughout, is more than I can understand.
