§ IV. What is true of the divisions of stone by chiselling, is equally true of divisions of bricks by pointing. Nor, of course, is the mere horizontal bar the only arrangement in which the colors of brickwork or masonry can be gracefully disposed. It is rather one which can only be employed with advantage when the courses of stone are deep and bold. When the masonry is small, it is better to throw its colors into chequered patterns. We shall have several interesting examples to study in Venice besides the well-known one of the Ducal Palace. The town of Moulins, in France, is one of the most remarkable on this side the Alps for its chequered patterns in bricks. The church of Christchurch, Streatham, lately built, though spoiled by many grievous errors (the iron work in the campanile being the grossest), yet affords the inhabitants of the district a means of obtaining some idea of the variety of effects which are possible with no other material than brick. § V. We have yet to notice another effort of the Renaissance architects to adorn the blank spaces of their walls by what is called Rustication. There is sometimes an obscure trace of the remains of the imitation of something organic in this kind of work. In some of the better French eighteenth century buildings it has a distinctly floral character, like a final degradation of Flamboyant leafage; and some of our modern English architects appear to have taken the decayed teeth of elephants for their type; but, for the most part, it resembles nothing so much as worm casts; nor these with any precision. If it did, it would not bring it within the sphere of our properly imitative ornamentation. I thought it unnecessary to warn the reader that he was not to copy forms of refuse or corruption; and that, while he might legitimately take the worm or the reptile for a subject of imitation, he was not to study the worm cast or coprolite.
