Though adjacent toa turnpike where hundreds are daily 
passing, and exhibiting abundant ochreous indications, its 
chalybeate character had remained unsuspected. It is now 
much frequented, being found very beneficial asa tonic. 
In the neighborhood + of Catskill I have met with several 
beds of rich marl; the proprietors were ignorant of the use 
of this earth in agriculture; and in the same vicinity, rocks 
and extensive beds of calcareous tufa, deposited by streams 
issuing from caverns in limestone hills. 
14. Catskill ch Se ea -—Estract from the above letter. 
The attention of the well inifortued reiddlents of pe 
has been of late excited to the study of | wee 
chemistry and agriculture, and they have y Srpadiae 
_ a scientific institution under the name of the ( Caichi Lyce~ 
um of Natural History, composed of between twenty and 
thirty resident, and as many coyresponding members, who 
evince much zeal, and have formed a small cabinet of miner- 
als and plants. The corresponding members are mostly of 
the learned professions, and resident in the counties of 
Greene, Columbia, Delaware, Ulster end Otsego, generally 
elected at their own tion. I think that i e 
Catskill Lyceum will become a numerous and efficient so- 
ciety, well calculated to disclose the. resources of the the region 
in which it is located. 
I have occasionally read to this society papers. on natura! 
History, dwelling more particularly upon ke exem- 
plify ingt ternal char- 
acters of mineralsmore familiar; I have pubdivouied to in- 
duce research by drawing their attention to valuable eel 
which, from the geological character of the river valley, 
mor nt districts, may be met with ; as silver, lead, ce pper, | 
lumbago, iron, gypsum, a alum all; coal, marble and: ma 
i have found in different parts of the Catskill mountains, ex- 
tensive ledges richly impregnated with alum, and salt licks 
in the same region. Some springs of Columbia and Greene 
county hold in solution muriate of soda. I have found 
new oe ae in the valley of the Hudson for galena, plum-

will explore the Catskill, Shuongunck and Highland ranges. —
