At two o'clock in the afternoon the conference held its open session at the "House in the Wood." The building is most interesting, presenting as it does the art and general ideas of two hundred and fifty years ago; it is full of historical associations, and the groves and gardens about it are delightful. The walls and dome of the great central hall are covered with immense paintings in the style of Rubens, mainly by his pupils; and, of these, one over the front entrance represents Peace descending from heaven, bearing various symbols and, apparently, entering the hall. To this M. de Beaufort, our honorary president, the Netherlands minister of foreign affairs, made a graceful allusion in his opening speech, expressing the hope that Peace, having entered the hall, would go forth bearing blessings to the world. Another representation, which covers one immense wall, is a glorification of various princes of Orange: it is in full front of me, as I sit, the Peace fresco being visible at my left, and a lovely view of the gardens, and of the water beyond, through the windows at my right. The "House in the Wood" was built early in the seventeenth century by a princess of the house of Orange, the grandmother of William III of England. The central hall under the dome, above referred to, is now filled up with seats and desks, covered with green cloth, very neat and practical, and mainly arranged like those in an English college chapel. Good fortune has given me one of the two best seats in the house; it being directly in front of the secretaries, who are arranged in a semicircle just below the desk of the president; at my left are the other members of our delegation, and facing me, across the central aisle, is Count Munster, at the head of the German delegation. This piece of good luck comes from the fact that we are seated in the alphabetical order of our countries, beginning with Allemagne, continuing with Amerique, and so on down the alphabet. The other large rooms on the main floor are exceedingly handsome, with superb Japanese and Chinese hangings, wrought about the middle of the last century to fit the spaces they occupy; on all sides are the most perfect specimens of Japanese and Chinese bronzes, ivory carvings, lacquer-work, and the like: these rooms are given up to the committees into which the whole body is divided. Up-stairs is a dining-hall in which the Dutch Government serves, every working-day, a most bounteous lunch to us all, and at this there is much opportunity for informal discussion. Near the main hall is a sumptuous saloon, hung round with interesting portraits, one of them being an admirable likeness of Motley the historian, who was a great favorite of the late Queen, and frequently her guest in this palace.
