Account of the Kaatskill Mountains. 15 
_ Between the village and the mountain, the country is al- 
tered in its appearance. Near the western end of the bridge, 
which crosses the Kaatskill.at the village, a hill rises to the 
height of 150 feet. The rocks which compose this hill are 
much more compact than those near the river. ey have 
ayaa blue colour and bear a much stronger resemblance 
trap. Half a mile west of this, a ridge of land rises to the 
hei ht — fifty feet, when the country changes to Carbonate 
of hese rocks are compact, and filled with petri- 
aatne at the clam, entrocite, Si often in so great quanti- 
ties as to compose one sixth of the rock. On the surface of 
pa Limestone tract, I observed ‘ice specimens of red 
asper. 
On ank of the Kaater: ball (a the limestone region 
which is about four miles in breadth,) there is a sulphurous 
spring,* which is covered by the stream when the water is 
high. The water of this spring is so nee impregnated 
with sulphur, as to alter the colour of the stream for some 
distance after its union with it. It has a Brae sulphurous 
taste, fabs rods below the junction of these waters. When 
ow the atmosphere around the spring is strongly 
imtprevinted with the odour of Sulphuretted ydrogen Gas. 
have been informed that a large piece of native sulphur, 
was found near this spring a little below the surface. 
Slate and Sand Stone tract. 
Two miles from the base of the mountain, the Limestone 
region terminates. Sand Stone immediately appears. The 
earth here assumes a more reddish appearance, and con- 
tinues of this colour to the mountain. Th stone ter- 
minates at the base of the mountain. As you aise the 
mountain, Slate begins to appear resting upon the sand stone
