The works of the great mine are wonderful, and visitors welcome to examine whatever they find interesting; any questions they wish to ask are graciously answered, although every one is busy. This is not a special favor to the exceptional few, but the courtesy shown to all. Visitors are also welcome to descend into the mine, but as an attendant is necessary on account of dangers to be avoided, a permit must be obtained at the office. Several other caves have been discovered in the Black Hills, the largest of which is the Davenport Cave at Sturgis. Very little exploration has yet been done in it, but indications are said to be that it will take rank among the large ones. At Galena, a new mining town of golden promise, there is reported to be an Ice Cave, where ice forms at all seasons, and during the warm weather is a source of comfort and pleasure to the miners. In the evening, as train time for continuing the homeward journey approached, the snow storm which began gently early in the afternoon, grew steadily more severe. A carriage to the depot was not to be had, as every vehicle in town had gone to the funeral of an old-timer in the Hills and the return delayed by the storm. The situation could not be regarded as a special pleasure, but cave hunters learn to accept whatever is and be thankful for the general average. At the last moment, however, a team was driven up and permission given us to make use of it. It proved to be the private conveyance of the hotel proprietor, and the young boy who accompanied us, his son. Our train was on time, and the ride through the Hills to their southern limit, in the falling snow, was wonderfully beautiful; but the storm continued for many days and was one of the most severe on record. Those persons who have been so unfortunate as to permit themselves to accept a ready made opinion of dangers and roughness to be met with in the more newly settled regions, might find a tour of the Hills doubly interesting by making a supplementary study of "The Living Age," which cannot be so correctly viewed from a distance as is sometimes supposed, since the specimens exhibited are not always a true average of the strata they are supposed to represent.
