hike that of the Catskills, consisting of a regular succession of layers 
which are horizontally homogeneous and from which the phenomena 
of disruption are absent. The original disintegration and erosion of 
the mass which resulted in the production of the ranges was perhaps 
mainly influenced by the cirection of the jointage.. With this the trend 
of the ranges in the vicinity of the Kaaterskill Clove appears to coin- 
cide. The ravines, cloves, and deepest notches and valleys may be 
attributed to the streams of the present hydrographical basins, or to 
those connected with the ancient eastward and south-eastward inclina- 
tion of the stratum already considered. But recent observations on the 
juxtaposition and coincidence of the highest gaps in successive parallel 
ranges may possibly indicate the remnants—in cross-section—of the 
beds of ancient streams at that level (about 3000 feet); this conclusion, 
if confirmed, would signify an inclination of the plateau to the N.N.E. 
(or to the S.S.W.?) at a still earlier period, that immediately succeeding 
its elevation. 
Kames.—In the upper basin of the Kaaterskill, several isolated hills 
of gravel, etc., occur at an altitude ot 1924 feet, especially on the bank 
of the stream near the head of the Clove, which are probably kames ; 
their materials, though largely angular, show traces of imperfect strati- 
fication. Near ‘“ Blythewood,” on the North branch of the Schoharie 
creek, a curious conical and steep isolated kame rises 102 feet above 
the stream, made up of rounded pebbles of the Catskill grit, rarely a 
foot in length, overlying a layer of coarse moraine. Its elevation above 
the sea (1944 feet) exceeds that of any other kame yet observed, those 
of the Fintry Hills in England reaching 1280 feet, and those of the 
Androscoggin Lakes, in Maine, 1600 feet. A very interesting series of 
from eight to twelve very low kames—like parallel] ridges, often curv- 
ing, made up of large rounded boulders—-was also found to follow the 
course of the Kaaterskill near Palenville, in the Hudson Valley, at the 
mouth of the Clove, at an elevation of about 700 feet; these probably 
mark the course of the sub-glacial stream which issued from the mouth 
of the Clove. The paper concluded with observations on a deposit 
of laminated sand underlying the ground moraine: on the feeble erosion 
of the slopes of the Clove during the period which has elapsed since 
the close of the Glacial epoch; and ona new sec‘ion of the strata of 
South Mountain obtained from a recent road cutting. 
DISCUSSION. 
Prof. E. C. H. Day observed that one portion of Dr. Julien’s re- 
marks reminded him of an idea which had struck him many years ago, 
with regard to the ysurface geology of a valley on the south coast of 
England, near Charmouth, in Dorsetshire.
