Account of Schooley’s Mountain. 209 
Jersey. Not a single stream is known to pierce them. 
From their north-western slope, all their streams find their 
wiy into the Hudson and the Delaware. From their south- 
eastern declivity, their currents travel to the ocean by New- 
ark and Raritan bays. They have, however, no pretensions 
to be classed with the Shawanguok mountains, which are 
a distinct chain, and make part of the great Alleghany, that 
traverses the continent to the confines of Georgia. Nor 
have they any connexion with the Kaatskill mountains, 
which are themselves quite detached from the Shawangunk. 
Schooley’s monntain is of more moderate elevation than 
either. Geometrical measurement has ascertained that the 
height of Schooley’s mountain above its immediate base 
is more than six hundred feet. And a calculation made 
by approximation, on the falls of water at the different 
mill-dams along the hurrying channel of the Musconet- 
cunck, to its junction with the Delaware, and on the de- 
‘ scent thence to Trenton, makes the position of that base to 
be nearly five bundred feet more above tide-water. The 
elevation above the level of the ocean does not, therefore, 
in all probability, much exceed eleven hundred feet. And 
this is about the height ascribed to Anthony’s Nose, in the 
Highlands of New-York, by Mr. Knight. 
The elevation is, nevertheless, considerable enough to 
influence its temperature. The heats of summer are not 
so great as in the valleys. Droughts are less common and 
pinching. Snow falls earlier, and lies longer than in the 
adjacent plains. The warmth of a copious spring of pure 
water, as it issued out of the sand near the top of the moun- 
tain, was only 50 degrees, while the temperature of the 
water gushing from the briskest springs on the north side 
of Long-island, and drawn from the deepest wells at News 
York, is 54 degrees. The spring water on the summit of 
Schovley’s mountain is, therefore, four degrees colder than 
that around New- York. 
This mountain is not a mass of stratified rocks, piled 
upon each other from bottom to top. There is no peculiar 
difficulty in travelling over it. The predominating materials 
are clay and sand, forming a good ‘loam; which, though 
generally not argillaceous enough for the formation of 
bricks, is, at the same time, gravelly enough for the growth ° 
of grass and grain. Yet rocks are thickly distributed over 
its face and along its sides. They are mostly detached, 
though some of them are of large dimensions, They con- 
. sist chiefly of feldspar and quartz: the quartz is prone to 
be semipellucid, and is granular or angular, resembling
