Returning we drove by the ruins of the old city-wall, erected by the Mormons soon after they settled here, of concrete and adobe, as a defence against the Indians. The growth of the town and the disappearance of the Indians, rendered it useless years ago, and it was now fast falling to pieces, though no doubt of service in its day. It was one of Mr. Buchanan's Salt Lake scarecrows in 1857, but would not have stood a half-dozen shots from an ordinary field-piece, or even mountain-howitzer. The labor of erecting it, however, must have been prodigious, as it enclosed originally several square miles, and its remains even now speak well for the industry and enterprise of the saints in those early times. Thursday, Nov. 1st, was a great gala-day at Salt Lake, and we were fortunate to be there still. It was the chief day of their annual militia muster, and the whole country-side apparently turned out. The place selected was a plateau west of the Jordan, some three miles from Salt Lake city. Proceeding thither, we found a rather heterogenous encampment, with not much of the military about it, except in name. The officers were mainly in uniform, but the men generally in civilian dress, and many without either arms or accoutrements. As we passed through the encampment, they were all out at company drill. Of course, there were many awkward squads, but the so-called officers were the awkwardest of all. In many instances, they were unable to drill their men in the simplest evolutions; but stood stupidly by, in brand-new coats, resplendent with brass-buttons, while some corporal or private, in civilian dress, "put the company through!"
