When the cornices are finished, the walls are to be rough-cast as coarsely as possible, and when the rough-cast is nearly dry, the surface of sand must be shaped in such a way that the lengths are set out by the rule and square, the heights by the plummet, the corners by the set-square. For in this way the designs of the fresco-paintings will not be interfered with.
