published shortly. References to both books are inserted in footnotes.

At the end of what has been a long and engrossing task, it becomes a
pleasant duty to acknowledge the help which has been received from
teachers in school and college. Various chapters, either in manuscript or
in the proofs, have been read by Professor James M. Leake of Bryn Mawr
College; Professor J. C. Hildt of Smith College; Very Rev. Patrick J.
Healy, Professor of Church History in the Catholic University of America;
Professor E. F. Humphrey of Trinity College; Dr. James Sullivan, Director
of the Division of Archives and History, State Dept. of Education of New
York; Constantine E. McGuire, Assistant Secretary General, International
High Commission, Washington; Miss Margaret E. McGill, of the Newton
(Mass.) High School; and Miss Mabel Chesley, of the Erasmus Hall High
School, Brooklyn. The author would also express appreciation of the labors
of the cartographers, artists, and printers, to whose accuracy and skill
every page of the book bears witness.
