of a slide of fallen rocks which suggested its name. From its 
broad triangular top it sends a ridge toward the southeast, 
which divides the waters of the Esopus from those of the Ron- 
dout, and terminates in the Lone Mountain 8670 feet, by which 
it is almost connected with the Wittemberg chain. Another 
high ridge descends toward the south and nearly reaches the 
high group of Table Mountain 3865 feet, and Peak-o'-Mouse 
3875 feet, which separates the head waters of the Rondout from 
those of the East branch of the Navesink. It thus becomes the 
main hydrographic center of the region, sending its waters to 
‘the northwest by the Esopus; northeast to the same by the 
Woodland Creek ; south by the Rondout to the Hudson ; south- 
west by the Navesink to the Delaware. At 500 feet from the 
top, steep ledges, suddenly breaking the evenness of the ridge, 
mark the base of the cap of hard Subcarboniferous conglomer- 
ate (No. 10 of the 1st Pennsylvania Survey, according to James 
Hall) which crowns the king of the Catskills. An easy ascent 
is found by taking the road from Big Indian to the Helsinger 
Notch, from which the ridge, just beyond the Navesink waters, 
leads to the top by a regular and gentle slope. 
n the east several chains not yet well studied run from the 
neighborhood of the Slide between the Woodland Creek and 
the middle course of the Esopus) The most important is the 
rough chain of the Wittembergs. The highest points are from 
south to north, Cornell Mountain, 3681, near Lone Mountain 
and on the line of the Slide; Friday Mountain and Great Wit- 
temberg 3778 feet. Further to the east, and south of Shokan, 
High Point, celebrated for the beauty of its panorama, rises 
almost isolated from a low ridge to the altitude of 8098 feet. 
Between the Slide and Balsam range, on the south and west, 
and the Wittemberg chain, on the east, lies the central plateau 
of the Pantherkill, 7 miles wide each way, wild and wooded, 
entirely surrounded by the waters of the Esopus and the Wood- 
land Creek. It is surmounted by a long ridge running nearly 
due north from Slide Mountain with two prominent peaks, the 
highest of which, the Pantherkill Mountain, rises to an alti- 
tude of 8828 feet. It is deeply scooped out by torrents which 
eg their waters, on the west directly, and on the east by the 
oodland Creek, into the se 
On the southwest of the angle formed by the Fir and Hagle 
Mountains, but hardly connected with the main chain, rise two 
mountain peaks of still greater altitude, Graham Mountain, 
8886 feet, and Double Top, 3875 feet, called respectively, by 
the few settlers South Mountain and Round Top. I have 
already said that my reason for changing these names was to 
avoid the confusion arising from their frequent repetition. 
These two high peaks, cloudy connected together, are situated,
