Professor Nippold gives a characteristic letter which he received from the Empress, evidently on the subject of those historical studies of the House of Hohenzollern to which, as we have already mentioned, the Emperor Frederick at one time devoted himself with ardour. The letter is so interesting, especially in the views which it expresses on the subject of royal biography, that to quote it in full needs no apology:
"DEAR PROFESSOR,--Many thanks for sending the separate pages from the _Deutsche Revue_ of February, and for your excellent report, which has so much in it that does my heart good. You mean well and truly, not only as regards history, but also with the noble men who now lie in their graves, and whose deeds and influence should be properly appreciated in wide circles and through the proper medium.
"The work grows, however, even as you work upon it; the subject becomes more and more important, and one should ask oneself whether the time has come thus to lift the veil. Would it not be wiser and more cautious to close these papers for the _Revue_, and then to continue your labours, so that later a book could appear for which we could utilise this material, but not lightly or too soon? The letter of which you send me a copy--from our Kaiser Friedrich Wilhelm IV--should not, for instance, appear without the letter from my father, but that would arouse a fearful storm of discussion. In the political world there is so much tinder ready that one must do all one can to avoid bringing in anything exciting.
"As long as Bismarck is alive, it is very difficult! Also these things affect my mother, so that I should like very much to have a serious talk with you before the publication continues in the _Deutsche Revue_. Professor Ranke has handled the life of Friedrich Wilhelm IV as the Court here wished it to be treated. Similar books have now appeared, with authorisation, with regard to the Kaiser Wilhelm, and in Weimar, I believe, someone is writing a book on the Kaiserin Augusta. All these writers, however, are strictly conservative and orthodox in religion (therefore one-sided), and of all those currents which flowed into the lives of the dead, no word is spoken, in the sense that I mean. It is impossible thus to omit and yet give the public a true picture of the persons, of their time, and of the parts they played. You will see for yourself the consequences of such publication. You have more experience than I, and perhaps you can reassure me."
