From Detroit, on Feb. 4th, we went to Ypsilanti (at which place Mr. Müller preached three times, and addressed about 200 students of the Normal School, or State College who were being trained for teachers), and from Ypsilanti proceeded to Ann Arbor, where, on Sunday morning, Feb. 8th, he addressed a union meeting of Germans in their own language at a German Church. On that evening also, at the great University Hall (the largest in the State of Michigan) he addressed a mass-meeting, consisting of about 1,000 students out of the 2,000 who belong to the University, and 1,800 persons from churches which had been closed, that their members might attend this service. From the platform of the Hall (a large semi-circular building), just before the sermon, Dr. Brown, of the Presbyterian Church, made a short opening speech, and concluded his remarks by saying:--"We have for years, Mr. Müller, been acquainted with your life and labours; we thank God for you; your work has been an inspiration to us, and we now most heartily welcome you to the University and to the Churches of Ann Arbor." My husband then addressed the vast audience for an hour, and spoke particularly to the students who formed a large portion of the congregation. The following brief account of this University may here be considered interesting:-- "The University of Michigan, located in Ann Arbor, is one of the noblest Institutions in the land. With fees little more than nominal, and with a standard of scholarship as high as any College or University in the country, it numbers amongst its students natives of every part of the globe. The University buildings occupy a square of ground, each front of which is nearly a quarter of a mile in length. There are no dormitories, all the space being devoted to purposes of instruction. The library is large and constantly increasing; the geological collection is one of the most perfect in the country; there is a fine art gallery; and the medical museum is complete." Before our departure, Mr. Müller preached at the Presbyterian Church, and held a second German service on Feb. 10th. On the 11th we left Ann Arbor for Olivet, but, in consequence of a railway accident, our journey was delayed; and having to pass one night at Jackson on the way, and to drive through Charlotte to another station, we did not reach our destination until Thursday afternoon the 12th. At Olivet, a little village, remarkable chiefly for its College, my husband preached only twice; and on the latter occasion addressed the College students (of whom there were about 300) at the Church belonging to the Institution.
