A second printing affords a grateful opportunity for recalling that this little book is a sign of the co-operating thoughts and sympathies of many persons. Its indebtedness to Mrs. Emmons Blaine is partly indicated in the dedication. From my friends Mr. and Mrs. George Herbert Mead came that interest, unflagging attention to detail, and artistic taste which, in my absence, remade colloquial remarks until they were fit to print, and then saw the results through the press with the present attractive result—a mode of authorship made easy, which I recommend to others fortunate enough to possess such friends. 去书内
