Whilst the greatest effort has been made to ensure the quality of this text, due to the historical nature of this content, in some rare cases there may be minor issues with legibility. Among the generous criticisms of the book that appeared five years ago was a special comment by George Edward Wood berry in approval of the 'blending of scholarship and travel the research side imparting a touch of romance, and dignifying the travel.' I hope that the present pages may not be found to fall too far below the standard which the critic demanded to have maintained. For that reason I have refrained, as before, from an earlier idea of labeling certain chapters as 'dedicated to the special student,' because of their more technical con tents, and of designating others as 'dedicated to the general reader.' It will not be found difficult, I think, to] distinguish the appeal in either case.
