Note 125:2 — III

[It has seemed best in this volume not to attempt to deal with the French frontier or the Spanish-American frontier. Besides the works of Parkman, a multitude of monographs have appeared in recent years which set the French frontier in new light; and for the Spanish frontier in both the Southwest and California much new information has been secured, and illuminating interpretations made by Professors H. E. Bolton, I. J. Cox, Chapman, Father Engelhart, and other California and Texas investigators, although the works of Hubert Howe Bancroft remain a useful mine of material. There was, of course, a contemporaneous Old West on both the French and the Spanish frontiers. The formation, approach and ultimate collision and intermingling of these contrasting types of frontiers are worthy of a special study.]
