On looking at the southern and more distant Catskills from the Hudson River on the east, or on looking at them from the west from some point of vantage in Delaware County, you see, amid the group of mountains, one that looks like the back and shoulders of a gigantic horse. The horse has got his head down grazing; the shoulders are high, and the descent from them down his neck very steep; if he were to lift up his head, one sees that it would be carried far above all other peaks, and that the noble beast might gaze straight to his peers in the Adirondacks or the White Mountains. But the head and neck never come up; some spell or enchantment keeps it down there amid the mighty herd; and the high round shoulders and the smooth strong back of the steed are alone visible. The peak to which I refer is Slide Mountain, the highest of the Catskills by some two hundred feet, and probably the most inaccessible; certainly the hardest to get a view of, it is hedged about so completely by other peaks,—the greatest mountain of them all, and apparently the least willing to be seen; only at a distance of thirty or forty miles is it seen to stand up above all other peaks. It takes its name from a landslide which occurred many years ago down its steep northern side, or down the neck of the grazing steed. The mane of spruce and balsam fir was stripped away for many hundred feet, leaving a long gray streak visible from afar. Slide Mountain is the centre and the chief of the southern Catskills. Streams flow from its base, and from the base of its subordinates, to all points of the compass,—the Rondout and the Neversink to the south; the Beaverkill to the west; the Esopus to the north; and several lesser streams to the east. With its summit as the centre, a radius of ten miles would include within the circle described but very little cultivated land; only a few poor, wild farms in some of the numerous valleys. The soil is poor, a mixture of gravel and clay, and is subject to slides. It lies in the valleys in ridges and small hillocks, as if dumped there from a huge cart. The tops of the southern Catskills are all capped with a kind of conglomerate, or "pudden stone,"—a rock of cemented quartz pebbles which underlies the coal measures. This rock disintegrates under the action of the elements, and the sand and gravel which result are carried into the valleys and make up the most of the soil. From the northern Catskills, so far as I know them, this rock has been swept clean. Low down in the valleys the old red sandstone crops out, and, as you go west into Delaware County, in many places it alone remains and makes up most of the soil, all the superincumbent rock having been carried away.
