4So in buildings, which are constructed on piers and arches, consisting of wedges whose joints are concentric, the outer piers should be wider than the others, that they may have more power to resist the action of the wedges, which, loaded with the weight of the superincumbent wall, press towards the centre, and have a tendency to thrust out the abutments. But if the outer piers be of large dimensions, by restraining the power of the wedges they will give stability to the work.
