 upon architecture yet written in America, as well as 

 one of the foremost contributions to the literature 

 of the subject which has appeared in any country. 

 The illustrations, nearly 200 in number, are most ex- 

 cellent in character, and aid materially in the eluci- 

 dation of the text. Mr. Moore's book is an honor to 

 American scholarship and investigation, and de-

 a most interesting subject."— ^Bos^ort Advertiser.
