Regarded by many as the stonemason's bible, Practical Masonry has for many years been one of the best technical stone masonry books available for both apprentices and experienced masons. Originally written in 1896 and published by Crosby Lockwood & Son of London, it met with great acclaim and the correspondence received by the author was that of thanks and praise at such a well written and concise technical book. Following the constructive feedback W R Purchase wrote a second edition in which he included three more chapters: Roman and Grecian moldings (both illustrative) and a glossary of terms. This work was then followed by further editions and by 1904 when the fifth edition was published Purchase had added further chapters including: Masonry Estimating and Quantity Surveying; Building Stones, marble and granite (including detailed lists of specific stones available) and finally Tables of Diameters, Circumferences and Areas of circles. As with many technical books that go out of print it became more difficult for people to purchase this book as the years passed. This latest edition published by Donhead Publishing will ensure that the work of W R Purchase can again reach and assist all those who study or are involved with this ancient craft.
