In thanking those who have so courteously assisted in the preparation of this book, acknowledgment must first of all be made to Miss Mary Harrod Northend, to whose suggestion the undertaking was entirely due, and whose illustrations have, in large measure, made it possible of realisation. The author gratefully records his indebtedness also to Messrs. J. B. Lippincott Company, of Philadelphia, for permission to use a number of illustrations of Pennsylvania houses that appeared in “The Colonial Homes of Philadelphia and its Neighbourhood”, by H. D. Eberlein and H. M. Lippincott, and likewise for permission to reproduce an illustration of the Adam Thoroughgood house from “Historic Virginia Homes and Churches”, by Robert A. Lancaster, Jr.; to the Architectural Record for permission to incorporate, in chapters IV, VIII and XI, parts of papers contributed to that magazine; to Dr. George W. Nash of Old Hurley, for generous assistance in supplying many illustrations drawn from a wide geographical area; to H. L. Duhring, Jr., of Philadelphia, for suggestions that bore important fruit in the progress of the work and for the illustration of the Saal at Ephrata; to Messrs. R. A. Lancaster, Jr., G. C. Callahan and Joseph Everett Chandler for sundry items of assistance; to the Librarian and staff of the Library Company of Philadelphia, and to the Librarian and staff of the Pennsylvania Historical Society for continued courtesies while the following pages were in course of preparation, to the Brickbuilder, to Mr. Edmund C. Evans and, finally, to Messrs. Horace Mather Lippincott and Philip B. Wallace for valuable help in the matter of photographs.
