It will have afforded the Author sincere gratification if the contents of this little work have found favour in the eyes of the Reader, and have been a ready help to him in his efforts in Architectural Modelling. Next to the pleasure of learning, is that of imparting knowledge. The Author has endeavoured, to the best of his ability, to render all his instructions clear and practical, at the same time divesting them of all unnecessary technicalities, and rendering them as terse as possible.
