In a letter to Tuesday's Times, Mr. Longsdon mentions that
the German system of roughing horses is better in the following respect than the English ; namely, that the studs used to prevent the horse from slipping are made so as to screw out and in, are taken out by the groom when the horse returns to his stable, and are then re- placed by a button, to keep the aperture into which the screw goes, free from the dirt. Thus the horse when at rest cannot injure himself, as a roughed horse in England often does, with the studs put on to prevent his slipping when he is out. At present we provide against one danger by subjecting our horses to another almost, if not quite, as great, only to save our grooms a little trouble.
