Singularly enough, both met the same end, by fire; the _Missouri_ being burned in the Bay of Gibraltar in 1843, the _Mississippi_ in the river whence she took her name, in the course of Farragut's passage of the batteries at Port Hudson in 1863. This engagement marked the end of the admiral's achievements in the river, throughout which, beginning with the passage of the forts and the capture of New Orleans, the _Mississippi_ had done good work. At the time of her destruction, the present Admiral Dewey was her first lieutenant. Besides these two we had the _Susquehanna_, "paddle-wheel steam-frigate," which also served manfully through the war, and was in commission after it. It was she that carried General Sherman on his mission to Mexico in 1866. As usual, the principal European navies had built many more of these vessels; that is, had adopted improvements more readily than we did. During my first cruise after graduation, on the coast of Brazil, 1859-61, the British squadron there was composed chiefly of paddlers; the flag-ship _Leopard_ being one. As I remember, there was only one screw-steamer, the sloop-of-war _Curacao_. By that time, however, the paddlers were only survivals; but it may be noted, in passing, with reference to the cry of obsolescence so readily raised in our day, that these survivals did yeoman service in the War of Secession. It is possible to be too quick in discarding, as well as too slow in adopting. By 1850 the screw had made good its position; and the difficulty which had impeded the progress of steam in men-of-war disappeared when it became possible to place all machinery below water. There were, however, many improvements still to come, before it could be frankly and fully accepted as the sole motive power. It is not well to let go with one hand till sure of your grip with the other. So in the early days of electric lighting prudent steamship companies kept their oil-lamps trimmed and filled in the brackets alongside of the electric globes. Apart from the problem experienced by the average man--and governments are almost always averages in adjusting his action to novel conditions, the science of steam-enginery was still very backward. Notably, the expenditure of coal was excessive; to produce a given result in miles travelled, or speed attained, much more had to be burned than now, a condition to which contributed also the lack of rigidity in the wooden hulls, which still held their ground. Sails were very expensive articles, as I heard said by an accomplished officer of the olden days; but they were less costly than coal. Steam therefore was accepted at the first only as an accessory, for emergencies. It was too evident for question that in battle a vessel independent of the wind would have an unqualified advantage over one dependent; though an early acquaintance of mine, a sailmaker in the navy, a man of unusual intelligence and tried courage, used to maintain that steam would never prevail.
