Here is a meritorious little work setting forth in clear fashion the principles of descriptive geometry and of shades and shadows. The author has followed consistently his prefatory announcement of due consideration to the engineering point of view. "The information contained herein was compiled with special attention for its use as a text book on shades and shadows. Architectural students in many colleges receive their early training under engineering teachers. An attempt was therefore made to serve such students, by assuming the point of view of their engineering training at the beginning of the book, and lead them by a study of shades and shadows toward an appreciation of the artistic architectural point of view, so seldom developed in a strictly engineering course." The illustrations are very numerous and adequately present the methods of descriptive geometry and shades and shadows. A number of very pleasing architectural drawings-some of them the work of students-illustrate the applications of the methods and lend attractiveness and interest to the work. Numerous problems are given at the ends of the various sections. The final section treats briefly of wash rendering-a subject on which there is the following interesting comment in the forepart of the book: "They often resort instead to mere copying, to the use of shades and shadows merely guessed at, and to a lavish rendering to cover mistakes. The beauty and impressiveness of a drawing is more truthfully enhanced by the accurate casting of its shadows than by its rendering." -Engineering and Contracting, Vol. 55 [1921]
