Decorative and Higher Art. A Gazette of Architectural Opera- tions : — The Materials to be supplied by the Members of the Profession. We intend to afford a medium for the interchange of thought and taste throughout the profession, but not for the settlement of disputes. Here, men of culture may commune with one another, upon the general topics belong- ing to our sphere ; but will not be licensed to rail. Articles, designs, and experiments will constantly appear from artistic and scientific writers of repute ; and we cor- dially invite communications and designs from the profession, and all individuals interested in any matter related to our undertaking. Our own designs, as well as our own articles, will appear un- signed. Accepted volunteer designs and articles will have their authors desig- nated, unless they themselves desire otherwise. Those who wish their articles or designs to appear in type, or engraving, after editorial approval, will be careful to write all proper names very legibly, and all words of the language, deci- pherable by context, as plainly as may be ; to use only one side of the paper : to conform in their drawings to the size indicated by the page of this Prospectus, which is that of the book itself; and to send their names and addresses, not for publication, but for responsibility's sake ; as any assumed signatures they please will be printed with their essays. No rejected manu- scripts returned. Our aim is, to cultivate the kindest relations with all members of the engi- neering and architectural professions throughout the country. Every well- informed architect understands that the diffusion of designs and estimates tends to augment his income. Every intelli- gent gentleman knows that, while archi- tectural works enlarge his mind and improve his taste, they cannot, when he resolves to build, save him any money ; though he may lose much, in cash, comfort and beauty, by not em- ploying practised skill. The individual of fewer opportunities, who is content to follow a published plan, will not con- sult an architect, until he himself, from unlucky experience, learns that it re- quires professional knowledge to carry forward either his own or others' ideas to a useful result. Our production will not be stinted in embellishments. Eveiy part will con- tain at least four designs, with plans, elevations, details, general descriptions, and close approximate costs, embody- ing dwellings and stores adapted to town or city, country residences, cot- tages, villas, mansions, public buildings, halls, chapels, churches, lodges, bridges, monuments, tombs, fountains, summer-
