_British Architect_: "The writer manages to say a good many interesting things. Mr. Sherrill's book is written in a most interesting style." _Architectural Review_: "A useful book. Mr. Sherrill has an acute appreciation of the important relationship between the glass and the surrounding architecture, and he has brought the fresh mind of the amateur to his subject." JOHN LANE, THE BODLEY HEAD, VIGO STREET, LONDON, W. TRANSCRIBER'S NOTE: Minor changes have been made to correct typesetters' errors; otherwise, every effort has been made to remain true to the author's words and intent.
