I have not noticed any other animadversions on the “Seven Lamps” in Mr. Garbett’s volume; but if there be more, I must now leave it to his own consideration, whether he may not, as in the above instances, have made them incautiously: I may, perhaps, also be permitted to request other architects, who may happen to glance at the preceding pages, not immediately to condemn what may appear to them false in general principle. I must often be found deficient in technical knowledge; I may often err in my statements respecting matters of practice or of special law. But I do not write thoughtlessly respecting principles; and my statements of these will generally be found worth reconnoitring before attacking. Architects, no doubt, fancy they have strong grounds for supposing me wrong when they seek to invalidate my assertions. Let me assure them, at least, that I mean to be their friend, although they may not immediately recognise me as such. If I could obtain the public ear, and the principles I have advocated were carried into general practice, porphyry and serpentine would be given to them instead of limestone and brick; instead of tavern and shop-fronts they would have to build goodly churches and noble dwelling-houses; and for every stunted Grecism and stucco Romanism, into which they are now forced to shape their palsied thoughts, and to whose crumbling plagiarisms they must trust their doubtful fame, they would be asked to raise whole streets of bold, and rich, and living architecture, with the certainty in their hearts of doing what was honorable to themselves, and good for all men.

Before I altogether leave the question of the influence of labor on architectural effect, the reader may expect from me a word or two respecting the subject which this year must be interesting to all—the applicability, namely, of glass and iron to architecture in general, as in some sort exemplified by the Crystal Palace.

It is thought by many that we shall forthwith have great part of our architecture in glass and iron, and that new forms of beauty will result from the studied employment of these materials.

It may be told in a few words how far this is possible; how far eternally impossible.

There are two means of delight in all productions of art—color and form.

The most vivid conditions of color attainable by human art are those of works in glass and enamel, but not the most perfect. The best and noblest coloring possible to art is that attained by the touch of the human hand on an opaque surface, upon which it can command any tint required, without subjection to alteration by fire or other mechanical means. No color is so noble as the color of a good painting on canvas or gesso.

This kind of color being, however, impossible, for the most part, in architecture, the next best is the scientific disposition of the natural colors of stones, which are far nobler than any abstract hues producible by human art.

The delight which we receive from glass painting is one altogether inferior, and in which we should degrade ourselves by over indulgence. Nevertheless, it is possible that we may raise some palaces like Aladdin’s with colored glass for jewels, which shall be new in the annals of human splendor, and good in their place; but not if they superseded nobler edifices.

Now, color is producible either on opaque or in transparent bodies: but form is only expressible, in its perfection, on opaque bodies, without lustre.
