On March 28th we left Cassel and went to Halle, _viâ_ Eisenach, to visit the Wartburg (an old Castle standing on a steep hill, 1,355 feet in height, where Luther was concealed in 1521) and explored the interior of the building. The sitting-room, occupied by the great Reformer, when he translated the Scriptures into German, is shown to visitors. His chair also, and an old bedstead upon which he slept, are preserved as objects of interest. The Wartburg contains a small chapel likewise, and numerous valuable relics. At 9 in the evening we reached Halle. The next afternoon Mr. Müller spoke at the great Hall of Francke's Orphan Institution from Heb. xi. 4, and on March 30th gave an address on prayer at the same Hall, upon which occasion he made particular reference to the life and labours of Francke, because the example set by that devoted servant of Christ of founding an Orphan Institution, in dependence upon God alone for help, was a great encouragement to him when he began his Orphan Work in Bristol. Whilst at Halle we went through the Orphan Asylum, founded by Francke in 1698, and visited the different departments of the Institution. My husband called also upon his old friend Dr. Tholuck, Counsellor of the Upper Consistorium of Prussia, and Professor of Theology at the University of Halle, who was then living. On March 31st we left Halle for Berlin, and on the way there went to Wittenberg, a fortified town on the Elbe, to visit the Schlosskirche, which contains the tombs of Luther and Melancthon. Here, too, we saw the Church doors upon which, on Oct. 31st, 1517, Luther's 95 Theses against the doctrine of Indulgencies were posted up, introducing the Reformation; and at an old Monastery were conducted to the room where he lived as an Augustine Monk, and shown the cup out of which he used to drink. In the market place is a great bronze statue of the Reformer, and another of Melancthon near it. We visited an Oak also, which marks the spot where, on Dec. 10th, 1520, Luther burned the Pope's bulls; saw the exterior of Melancthon's house; and afterwards, continuing our journey by rail, arrived at Berlin late the same evening. There, as long as we remained, Mr. Müller preached nearly every evening at one of the various places of worship in the city, and held meetings at St. Johannes Kirche, Old Moabit, the Erste Vereins Haus, the Christus Kirche, the Moravian Brethren's Hall, etc. On Sundays he preached regularly twice. The audiences generally were very large. On April 7th, Count Bismarck, (a cousin of Prince Bismarck), came a distance of 125 miles on purpose to see and hear him, because my husband's Narrative had been made a great blessing to his soul.
