We as utterly despise any falsehood in construction as our honestly outspoken contemporary, and will at every opportunity disclose and denounce its adoption in this country in all cases where there is any pretension to architectural design. For a new country like this, it is at least creditable that, even in a small class of dwellings, the architect is, as a general thing, called on to design and frequently to superintend—every thing is not left to the builder as in London. Yet there is and always will be in this as in all other countries a large class of private buildings outside the pale of legitimate taste; creations ungoverned and ungovernable by rule. But such should never be taken as examples of the existing state of the constructive art of the day; they should rather prove the unfortunate exceptions to the fact of its position. Even these it will be our duty to watch over and try to set right; for we are ardent believers in the influential power of information, and look with assurance to the education of our people generally on this subject of judgment and taste in building as the infallible means of turning to good account the remarkable progress in that constructive art of the American nation, which the observant London _Builder_ notices with the generous well-wishing of a kindly professional brother. THE MANSARD MADNESS. Of all the intellectual qualifications which man is gifted with, there is not one as sensitive as that which enables him to discern between what is intrinsically good, and what is bad or indifferent to his eye. Yet are there none of all man’s mental attributes so frequently and so grossly outraged as is this to which we now allude, called Taste. Custom has much to say in the question of arbitrary rule which taste so imperatively claims. Persistence in any thing will, of necessity, make itself felt and recognized, no matter how odious at first may be the object put before the public eye, and ultimately that object becomes what is commonly called “fashionable.” This apparent unity of the public on one object is variable and will soon change to another, which in its turn will seem to reign by unanimous consent and so on _ad infinitum_. In Architecture this fickle goddess, Fashion, seems to reign as imperatively and as coquettishly as in any or all the affairs of this world of humanity. That which was at first esteemed grotesque and ridiculous, becomes in time tolerable and at last admirable. But the apathy which sameness begets cannot long be borne by the novelty worshippers, and accordingly new forms and shapes remodel the idea of the day, until it ceases to bear a vestige of its first appearance and becomes quite another thing.
