Excerpt from The Rudiments of Architecture and Building
The book on Building is edited from Dobson, and is intended as a First Book on the Art of Building, designed for the use of young persons who are about to commence their professional training for any pursuit connected with the erection of Buildings; and also for the use of amateurs who wish to obtain a general knowledge of the subject without devoting to it the time requisite for the study of the larger works that have been written on the different branches of construction.
