At work all the morning on my Grotius address Lunched at the "House in the Wood," and walked to town with sundry delegates. In the afternoon went to a "tea" at the house of Madame Boreel and met a number of charming people; but the great attraction was the house, which is that formerly occupied by John De Witt--that from which he went to prison and to assassination. Here also Motley lived, and I was shown the room in which a large part of his history was written, and where Queen Sophia used to discuss Dutch events and personages with him. The house is beautiful, spacious, and most charmingly decorated, many of the ornaments and paintings having been placed there in the time of De Witt. June 27. At all sorts of work during the morning, and then, on invitation of President Low, went with the other members of the delegation to Haarlem, where we saw the wonderful portraits by Frans Hals, which impressed me more than ever, and heard the great organ. It has been rebuilt since I was there thirty-five years ago; but it is still the same great clumsy machine, and very poorly played,--that is, with no spirit, and without any effort to exhibit anything beyond the ordinary effects for which any little church organ would do as well. In the evening dined with Count Zanini, the Italian minister and delegate, and discussed French matters with Baron d'Estournelles. He represents the best type of French diplomatist, and is in every way attractive. Afterward to Mr. van Karnebeek's reception, meeting various people in a semi-satisfactory way. June 29. In the morning, in order to work off the beginnings of a headache, I went to Rotterdam and walked until noon about the streets and places, recalling my former visit, which came very vividly before me as I gazed upon the statue of Erasmus, and thought upon his life here. No man in history has had more persistent injustice done him. If my life were long enough I would gladly use my great collection of Erasmiana in illustrating his services to the world. To say nothing of other things, the modern "Higher Criticism" has its roots in his work. June 30. Engaged on the final revision of my Grotius speech, and on various documents. At noon to the "House in the Wood" for lunch, and afterward took a walk in the grounds with Beldiman, the Roumanian delegate, who explained to me the trouble in Switzerland over the vote on the Red Cross Conference.
