This book is intended for carpenters — for masters, journeymen and apprentices. It has long been the complaint of this class that architectural books, ih tended for their instruction, are of a price so high as to be placed beyond their reach. This is owing, in a great measure, to the costliness of the plates with which they are illustrated: an unnecessary expense, as illustrations upon wood, printed on good paper, answer every useful purpose. Wood engravings, too, can be distributed among the letter-press an advantage which plates but partially possess, and one of great importance to the reader.
