Injuries due to side bars being too curved occur about the middle of the back, and the curve cannot be reduced, so the only thing is, to fill up both ends of the side bar with strips of numnah, shaving them off to nothing as they approach the centre. More than one strip may be required at the extremities; in this, as in all other building-up operations with numnah, the personal equation of the operator, his capacity for grasping requirements, and his resourcefulness, make all the difference between success and failure.

Alterations for side bar injury
With panelled saddles it is comparatively simple to deal with alterations; they generally consist of more stuffing, which only a trained saddler can do, or at least no one else attempts, though it is quite simple.

Balance of weight
There are few things which require more attention than the question of the balance of weight, pound for pound, ounce for ounce. There should be the same weight on the off side as on the near.in fact, to secure this adjustment it would even be better to add weight to the light side to bring matters into equilibrium, so important is it that the weight on a horses back should be equal on either side of the spine.

Injuries from fan
The fans of the side bar are capable of inflicting injury on the loins, the result of friction. The rolling action of the loins, previously described causes friction between them and the side bar. Very little contact suffices; the hair, as the result of friction, is shaved off as closely as if done by a razor, and over a patch the size of the palm of the hand. Occasionally the matter ends there; the oval-shorn patch remains, but undergoes no further change; if, however, the rear fans press on the loins with more force than is sufficient to shave the hair off, the next stage is a crop of pimples, heat and swelling, and the loins become extremely tender.
