At New Orleans my husband held many meetings, including services at the Canal Street Presbyterian, Carondelet Street, and Methodist Churches; he preached also in German, at three different places of worship, and gave two addresses, one to the 250 coloured students of Leeland College, and the other to the coloured students of Straight University, 215 in number. New Orleans, which is the chief cotton mart of the world, contains a large Roman Catholic, French, and Spanish population, and is said to be the most wicked city in the United States. During our visit, Popish processions frequently passed along the streets, and little or no regard was shown for the Lord's Day, when business was carried on as usual. Before our departure we visited the Orange Groves and Lake Pontchartrain; but with this exception, saw very little of the neighbourhood. On the afternoon of March 29th we went on board the "John Scudder," a large river steamer, and at 6 p.m. left New Orleans, and started on a voyage up the Mississippi, for Memphis, Tennessee. The room we occupied was rather large, and was one of a great number of cabins ranged along the sides of a very long saloon, used as a general sitting and dining-room by the passengers. It had two berths, six little windows--or ventilators--close to the ceiling, and two doors, one of which opened into the saloon. The food provided for the passengers was excellent, but no drinking water was to be had on board, except the unfiltered water of the Mississippi; and this was so full of impurities, and muddy sediment, which formed a thick deposit on the bottom of any vessel where it was allowed to stand, that we could neither make up our minds to drink it cold, nor in the form of tea or coffee, particularly as it was said to have an injurious effect upon the health. We therefore obtained a jug filled with ice, allowed the ice to melt, and after mixing a little wine with the water, to take off the coldness of it, procured a wholesome palatable draught. On the evening of March 31st, Mr. Müller (by permission) held a meeting in the saloon, when he addressed the passengers, coloured servants, and as many of the ship's company as were able to attend; but though there were a few Christians on board who appreciated the service, the passengers were chiefly worldly people, who amused themselves every evening in the saloon with music, singing, dancing, and card-playing, from which there was no escape, as in our cabin, we could distinctly hear, even if we did not see, all that was going on. The voyage, however, though slow, was a pleasant one upon the whole. The Mississippi, or "Father of Waters," from its source in Minnesota, to its mouth in the Gulf of Mexico, is 3160 miles in length; but the _Upper_ Mississippi is considered much more beautiful than the lower portion of the river. Whilst on board, Mr. Müller was occupied a few hours every day in writing the new Report, and on April 3rd, at 6
