The combination of the last two engravings is probably intended to represent a hideous human face; the eyes and teeth appear in the first, and the projecting stone is perhaps intended for the nose or snout. It occupies a space in breadth equal to about five feet of the wall. To present the whole facade on the same scale would require an engraving sixty-four times as long as this. The reader will perceive how utterly unprofitable it would be to attempt a verbal description of such a facade, and the lines in the engraving show that, as I remarked in my former account, there is no tablet or single stone representing separately and by itself an entire subject, but every ornament or combination is made up of separate stones, each of which had carved on it part of the subject, and was then set in its place in the wall. Each stone by itself is an unmeaning fractional portion, but, placed by the side of others, makes part of a whole, which without it would be incomplete. Perhaps it may with propriety be called a species of sculptured mosaic; and I have no doubt that all these ornaments have a symbolical meaning; that each stone is part of a history, allegory, or fable. The rear elevation of the Casa del Gobernador is a solid wall, without any doorways or openings of any kind. Like the front, above the cornice it was ornamented throughout its whole length with sculptured stone. The subjects, however, were less complicated, and the sculpture less gorgeous and elaborate; and on this side, too, a part of the facade has fallen. The two ends are thirty-nine feet each. The following engraving represents the southern end. It has but one doorway, and of this, too, the sculptured subjects were more simple. The roof is flat, and had been covered with cement; but the whole is now overgrown with grass and bushes. [Engraving 12: Southern End of Casa del Gobernador]
