running S.E. and N.W. through Hunter Mt., 35 miles long. Toward 
the S.E., the descent from the crest of Hunter Mt. (Alt., 4038 feet), to 
Overlook Mt. (3150 feet), is $88 feet, in 9% miles, equivalent to 1 in 
56, or about 1° ; toward the N.W., from Hunter Mt. to Utsyanthe Mt. 
(3203 feet), the descent is 835 feet in 25 miles, equivalent to 1 in 158, or 
less than %°. 
Another similar series of maxima, however, occurs further to the 
westward, consisting of Graham Mt. (3886 feet), Bear-pen Mt. (3545 
feet), and Ashland Pinnacle (3420 feet), distant respectively 9, 12, and 
15 miles westward of the former series. This southward convergence 
of the axes of these two folds may probably account for the increased 
protuberance and greater elevations in the Southern Catskills. 
Newly determined altitudes Many new determinations have been 
made of points in the vicinity of the Clove, by means of an excellent 
aneroid, with constant reference to the numerous stations in the vicinity 
whose altitudes have been accurately obtained by Guyot. A few are

Glaciatzon of summzts.—All the crests near the Clove have been 
now examined. On none above an altitude of 2900 feet have glacial 
striz been found, in part because they consist of thinly laminated flags 
deeply disintegrated by frosts. The highest striae discovered were 
found on Parker Mt., ‘High ledge” (2874 feet), running S. 18° W. 
(magnetic), and under the roots of a-large tree on the SE. slope of 
Round Top, at an elevation of 2871 feet, running S. 35° E. However, 
in all cases, a marked difference exists in the slope of different sides of 
a peak, the E. and S.E. sides presenting a precipitous face, and the 
other sides more or less of a gentle slope, made up of low terraces. 
The highest striz yet found in the Catskills occur on Overlook Mt., 
at an elevation of about 3100 feet, implying a depth of ice in the Hud- 
son Valley Glacier of about or at least 3200 feet. Within the Kaaterskill 
basin, several miles distant from the Hudson valley, the overflowing 
ice stream became shallower, having an altitude of about 3000 feet. 
It thus appears that the surface of the glacier inclined westward over 
these mountains, with a slope of 200 feet in 3 miles, 1 in 84, say about
