America 213 lakes, with especial reference to the history of the Niagara region". The Department of History appointed by Governor Pennypacker and the Jamestown Exposition Commission of Pennsylvania, as already noted, has been actively at work during the summer in preparing for the exhibit. The work is under the direction of Professor M. D. Learned, of the University of Pennsylvania, and Dr. Albert C. Myers, and has comprised much search in the records of the state and of its southeastern counties. Much material illustrative of the industrial and domestic life of the early settlers will be exhibited. Of especial interest to historians will be the series of historical maps — wall-maps, on a large scale, illustrating the extent of population at intervals of about twenty years. In their construction the frontier has been accurately determined, by means of land-warrants, surveys, patents, tax-lists, court records, and personal records, and the racial composition of the -population has been designated. There will also be special maps showing such economic and social features as roads, mills, and churches. The leading article in the Pennsylvania Magazine of History and Biography for July is by F. B. Sanborn : " The ' American Farmer ', St. John de Crevecoeur, and his Famous Letters (1755-1813)". Among the documents published in the issue we note " Extracts from the Journal of Rev.
