Here, again, as in the stone wall, the mortar joint plays a great part
in the final effect of the design. It can be safely set forth as a rule
that the rougher the texture of the brick used, the rougher and wider
should be the joint. For the smooth-faced brick the joint should be
small and finished with a tool. For a rough-faced brick the joint
should be large and rough in texture. The various forms of brick joints
in common use are shown in the illustrations.
