The characteristic noise is generally annoying to the master. Warmth, however, is popularly esteemed the cure for cold. The horse proprietor, therefore, thrusts his animal into an abode heated by impurity, only to find the annoyance aggravated. This fact is soon explained. Stables are not heated by fire or by water; their warmth is entirely derived from the fermentation of excrement. Were they well ventilated, efficiently built and cleanly kept, these places, having no artificial heat, must be cold; but the owner loves warmth; it feels so comfortable; it is so nice!
