At Bonn Mr. Müller addressed the Theological Students of the University; and at Barmen, spoke to the Missionary Students at the Mission House. Mülheim an der Ruhr, Barmen, and Elberfeld were found by us the green spots (spiritually) of Germany, where it was refreshing to be--on account of the great measure of spiritual life that existed there. The details, however, of all these services are not given, because it is undesirable to make this narrative too long; but it may be interesting to mention that at Stuttgart he was honoured by an interview with the Queen of Wurtemberg, who sent for him to the palace and asked a number of questions about the Orphan Work in Bristol; and on Jan. 13th, 1877, at Darmstadt, he held a drawing-room meeting at the house of the Court preacher, Mr. Bender, giving (by particular request) a short account of his life and labours to a large company of gentlemen and ladies assembled there. Upon this occasion four drawing-rooms were thrown open, and Princess Karl, (mother of Prince Louis of Hesse, husband of the late Princess Alice of England) Princess von Battenburg, and several gentlemen and ladies connected with the Court were present. The two Princesses shook hands with us very kindly afterwards, and expressed much interest in the account which had been given. On March 24th we left Barmen for Cassel, where, on Sunday morning, the 25th, at half past 9, Mr. Müller preached at the Brüder Kirche to about 500 people, and in the afternoon, at St. Martin's Kirche--the largest Church in the city--to only between 600 and 700, a circumstance which showed how low the state of spiritual life was at Cassel compared with that of Barmen, Elberfeld, and Mülheim, where the Churches were so thronged, that, even when the rain fell in torrents, they were not large enough to contain the people who crowded to the meetings, though many had to walk to them six, eight, or ten miles. The congregations, however, increased in size continually. Whilst at Cassel we took a drive to the Palace of Wilhelmshöhe, four miles distant, situated in a beautiful park, surrounded by extensive grounds where, in 1870, after his ignominious defeat at Sedan, Napoleon III., the late Emperor of the French, was sent as a State prisoner by the present Emperor of Germany.
