these rocks,) the fact that salt water is generally found m such de-

Mineral Springs. 
A chalybeate spnng was observed between Sidney Plains and Una- 
dilla, on the left hand side of the road that leads up the left bank of the 
Susquehannah. 
A similar one was seen between Unadilla and Franklin, in Delaware 
county. 
Another, discharging a considerable quantity of water, occurs in the 
meadow of the brook, about 2 miles from Bloomville, on the road to 
Kortright-Centre, on land of Nehemiah Every, Delaware county. 
Chalybeate waters flow from the marsh on the Beaverdam flats, \ 
mile above the mouth of Stratton's falls brook. Most of the springs 
are now covered over, in consequence of a bed of gravel and stones 
having been swept into the Delaware,* during the heavy freshet of last 
winter, by the Stratton's falls brook, and which has dammed up the 
former stream about two feet, 
Mr, Reed, of Hancock, informed me of a mineral spring in that 
township, on the east branch of the Delaware, on Mr, Thomas' farm, 
three miles above Shahocton, in Delaware county. From the descrip- 
tion, it is probably a sulphur spring, I did not see it. Ferruginous 
deposits, indicating chalybeate springs, were observed in many places 
along the route of the Erie rail-road, between Shahocton and Deposit, 
but most abundantly within four or Ave miles of Shahocton. 
Another chalybeate spring was seen on the farm of James Weed, 
ni the township of Walton, three miles above the village, in the valley 
of the west branch of the Delaware, in Delaware county. Bog ore is 
deposited from this water. 
A sulplmr spring rises from the alluvial gravel over the slate rocks 
of the Catskill mountain series, on the bank of creek, about 
* The upper part of the east branch of the Delaware, above the mouth of the 
Bushkill and Dry brook, is called the Beaverdam creek. Its name is appropriate, as 
it was formerly dammed up in many places by the beavers, which were once nume- 
rous on this stream. Long narrow ponds, of nearly still water, were formed in this 
way, and sometimes, also, by causes similar to that above mentioned, viz. by alluvial 
action.
