Every one that reads, every one that mingles in society, is constantly meeting with allusions to subjects on which he needs and desires further information. In conversation, in trade, in professional life, on the farm, in the family, practical questions are continually arising, which no man, well read or not, can always satisfactorily answer. If facilities for reference are at hand, they are consulted, and not only is the curiosity gratified, and the stock of knowledge increased, but perhaps information is gained and ideas are suggested that will directly contribute to the business success of the party concerned.

With a Cyclopædia, embracing every conceivable subject, and having its topics alphabetically arranged, not a moment is lost. The matter in question is found at once, digested, condensed, stripped of all that is irrelevant and unnecessary, and verified by a comparison of the best authorities. Moreover, while only men of fortune can collect a library complete in all the departments of knowledge, a Cyclopædia, worth in itself, for purposes of reference, at least a thousand volumes, is within the reach of all—the clerk, the merchant, the professional man, the farmer, the mechanic. In a country like ours, where the humblest may be called to responsible positions requiring intelligence and general information, the value of such a work can not be over-estimated.

PLAN OF THE CYCLOPÆDIA.

The New American Cyclopædia presents a panoramic view of all human knowledge, as it exists at the present moment. It embraces and popularizes every subject that can be thought of. In its successive volumes is contained an inexhaustible fund of accurate and practical information on Art and Science in all their branches, including Mechanics, Mathematics, Astronomy, Philosophy, Chemistry, and Physiology; on Agriculture, Commerce, and Manufactures; on Law, Medicine, and Theology; on Biography and History, Geography and Ethnology; on Political Economy, the Trades, Inventions, Politics, the Things of Common Life, and General Literature.

The Industrial Arts and those branches of Practical Science which have a direct bearing on our every-day life, such as Domestic Economy, Ventilation, the Heating of Houses, Diet, &c., are treated with the thoroughness which their great importance demands.

The department of Biography is full and complete, embracing the lives of all eminent persons, ancient and modern. In American biography, particularly, great pains have been taken to present the most comprehensive and accurate record that has yet been attempted.

In History, the New American Cyclopædia gives no mere catalogue of barren dates, but a copious and spirited narrative, under their appropriate heads, of the principal events in the annals of the world. So in Geography, it not only serves as a general Gazetteer, but it gives interesting descriptions of the principal localities mentioned, derived from books of travel and other fresh and authentic sources.

As far as is consistent with thoroughness of research and exactness of statement, the popular method has been pursued. The wants of the people in a work of this kind have been carefully kept in view throughout.
