Catskill mts. The Delaware 
springs from Lake Utsvantha 
2000 feet above tlie sea, and 
the Susquehannah 40 miles dis- 
tant from Lake Otsego 1200 
feet high. I visited the Rattle 
Snake hills, Otsego hills, Brim- 
stone falls 150 feet high, &c. 
This region is a table-land, 
western continuation of the 
Heidelberg, and which is twice 
cut through by the river Mo- 
hawk. I have brought from 
thence a tine collection of fos- 
sils, plants &c., some N. sp. 
many views &c. 
141. Physical Geography. 
Elevations of land and water , 
mountains and hills in the 
State of Mew York . 
The singular configuration 
of this state has but lately been 
noticed, when surveys were 
made for the canals and roads. 
In 1829, Joseph Henry read 
before the Albany Institute his 
topographical sketch of N. Y. 
which is published with a very 
uncouth section from East to 
West, and he has omitted the 
North and East of the state 
The geological sections of Prof. 
Eaton do not attempt to con- 
nect them with Physical Geo- 
graphy by graduated scales. 
All the map-makers took no 
notice of the mts. and table- 
lands of this state, until David 
Burr who in 1832 has at last 
delineated in part the N. Alle- 
ghanies and some other mts. of 
this state in his small map, re- 
duced from the large or county 
maps, wherein most of these 
mere flat surveys . it was also 
in 1832 that I drew those mts. 
in 'Fan hers new map. My 
labor and Burr’s being contem- 
poraneous and both original, 
may mutually correct each 
other. Mine is by no means 
perfect not having visited the 
whole state ; he had better ma- 
terials and opportunities, yet 
he is defective in the Catskill 
and Macomb mts. he lacks the 
Oquago mts. and all those be- 
tween Troy and Lake Cham- 
plain, &c. 
Having procured during my 
late journey in that state many 
additional materials, I shall 
now condense the whole in a 
general view. The following 
abbreviations will he used, H. 
for Henry, C. for W. Campbell, 
surveyor mpt. P. for Captain 
Partridge, 8. for Spafford, R. 
for Rafinesque. 
This state may be deemed di- 
vided into 6 parts, 3 level and 
3 lofty. 1. Long Island near- 
ly level and belonging to the 
great atlantic clysmian forma- 
tion extending hence to Flori- 
da. This island with Staten 
Island, Manhattan, &c., are 
properly the Delta of the R. 
Hudson ; but Staten Island has 
primitive hills and is not clys- 
mian. Manhalan is partly so. 
2. The valley of the Hudson 
as far as Glen’s Falls, and of 
the Mohawk, united with Lake 
Champlain, by a level of 14f 
feet. These valleys average 
from 200 to 500 feet. It is 
evident that when the sea was 
150 feet higher it must have 
mts. an omitted again } being jcr Tied these valleys by $
