In the evening we went to the theatre, and were interested in a drama with the title of "One hundred Wives," which had nothing whatever to do with the play--a piece written for the purpose of bringing into contempt the practices of the Saints in Utah, full of local incidents and acted with very considerable spirit. The sentiment of the audience was shown most unmistakably in the vigorous and sustained applause which greeted any situation or sentiment in which the Mormon leaders and their teachings were held up to contempt and hatred, and the curtain came down, amidst loud cheering, on a fine situation, in which half-a-dozen soldiers, in the uniform of the United States infantry, appeared to execute justice and to establish the predominance of the United States Constitution in the land of the Saints. There was some friction connected with the arrangements for our journey from Toledo to Detroit this morning. The general manager of the Lake Shore and Michigan Southern Railway was anxious that our train should run over his line instead of the Canada Southern, but Mr. Snow, passenger agent, who had come from Buffalo, applied to the customs authorities to pass the Fontaine engine across the border, in order to take the Duke over the other line. Our train consisted of what they call the combination baggage and smoking car, the Pullman hotel car Buckingham, a Pullman saloon belonging to the Pennsylvania Railway, and there was, moreover, the carriage of the general manager of the Lake Shore and Michigan Southern Railway, the whole drawn by the Fontaine engine, which is a production of the mechanical genius and intelligence of a gentleman of that name in the Southern States. We were bound by schedule to go forty-five miles an hour, and Mr. Fontaine explained the mechanism and the advantages which he claimed for his engine to the party. The Duke got upon the engine with him and proceeded out of the station, with a confidence which it turned out was quite justified, although I admit some persons, not quite so experienced, were rather uneasy at the experiment. We should have gone to pieces in very good company, and there would not have been wanting representatives of the Press, of the Detroit and Toledo papers, to have shared or to have recorded the ruin. The Duke drove the engine to the great satisfaction of the engineer, Mr. Fontaine. Mr. Cornelius Vanderbilt, informed of the proceedings, sent a telegram to know how the party were getting on just as we were leaving Toledo. At 2 o'clock we arrived safely in Detroit, where the mayor and several railway officials, Ex-senator Baldwin, Mr. Lord, and others were waiting to accompany the Duke and his friends in the "_Truant_" steam-yacht, belonging to Mr. Macmillan, in which we took a cruise upon the beautiful river that separates Canada from the United States.
