tween the counties of Ulster and Sullivan, on the Hudson and Delaware 
canal. Hitherto, however, these have not been attended with much 
success. The ore is indeed found, and with the same associates as at 
Wurtzboro', but in much less quantity. Some of the specimens of 
crytallized quartz obtained during the progress of these works are of 
great beauty. 
There is a sulphur spring at New-Paltz, which has within the last 
year excited some attention, and much is said concerning its medicinal 
properties. I have not yet had an opportunity of analyzing its waters. 
In addition to the above notices of the mineral productions of this 
county, it may be observed that there have been found in it, thin seams 
of coal, the appearances of which were so promising as to induce large 
expenditures in boring. Alum also occurs in several places as an efflo- 
rescence arising from the action of decomposing iron pyrites upon cer- 
tain clays. Graphite in small quantities is occasionally observed. 
WARREN COUNTY. 
This is situated in the great mineral region, and when properly ex 
plored it will no doubt be found to possess resources fully equal to those 
of the more northern counties. 
Of iron ore there are in Warren county, numerous and important lo- 
calities, embracing both the magnetic oxide and the hematite. Marl 
has also been found in Queensbury, and here too, as in many other 
places, it is associated with peat which is no less valuable than the pre- 
ceeding. 
Graphite, resembhng that from the celebrated locality at Ticonde- 
roga, is said to occur in workable beds in the towns of Johnsburgh and 
Athol. Porcelain clay has also been found in this county, which has 
been pronounced to be of good quality by those who are fully compe- 
tent to decide in regard to such matters. Besides these, there are valu- 
able beds of marble. 
To the mineralogist. Warren county is one of great interest, and if 
the catalogue of its minerals is not extensive, we are to recollect that it 
has been but partially explored. The following are credited to it, in 
addition to those already noticed : 
Crystallized quartz — Formerly abundant at Diamond island, in Lake 
George, and presenting some rare forms.
