With practically no more harness than a trace and collar, in the case of tramway or bus stables, each horse's harness can be hung upon his own stall-post. A special harness-room, except as a store, is hardly required; but in these large stables, where the horses are counted by the hundred, a harness-repairing shop and a forge or shoeing-shop will each form a most important branch. A number of loose-boxes for horses sick or temporarily disabled, or on trial, will be very necessary. One for every eight or ten horses kept will not be too many. In stables of this size an engine and boilers to supply the power for cutting up the fodder and bruising and mixing the corn, and in some eases for pumping water, are indispensable, and will keep a special staff of assistants in full work cutting, weighing, and filling into bags. In the passages between the various ranges of stables, strong rings should be built into the wall to secure the horses while being groomed, though a regular washing-and-grooming shed may be more convenient and offer greater facilities for inspection. All provisions for cleanliness are of even greater importance than in the gentleman's stable. The manure-pit must not be large and must have sides and bottom impervious to moisture, and the removal should be daily. In the stables of one of the best-managed tramway companies the principal walls, etc, are whitewashed monthly, and at the horses' heads every week. Lime wash is a great and cheap purifier.

In many large city stables, still further to economize space, the horses are accommodated on two stories, the upper part being reached by an inclined plane or gangway. This gangway has to be made with cross pieces of wood, well covered with gravel or litter to prevent slipping. The floor of the upper stalls is best made of steel joists and concrete, which, with the great modern facilities for the production of these articles, involves very little extra trouble or expense. Naturally a little more care will have to be taken with the ventilation and lighting of the lower story; and indeed, where possible, it is better to utilize this for subsidiary purposes, such as forges, harness-repairing, etc.
