limestone; also on the mountain east of Green river, about a quarter of 
a mile from the inn formerly kept by Hatch. Mr. Prescott says this is 
the blue copper ore, in a narrow vein, and that a similar one occurs in 
Hillsdale, on the farm formerly owned by Mr. Jesse Squire. Copper 
pyrites occurs rather abundantly in the Ancram lead mine, but not 
enough to be worth separating. 
Copper pyrites was observed in the siliceous slate, on the road from 
Lower Red-Hook to Upper Red-Hook Landing, but in small quantity. 
It is on Nathan Beckwith's land. 
Galena has been found in several localities in New-Lebanon. Lead 
ore occurs in an old mine in Livingston, on the farm of John E. H. 
Plass. Pyrites and blende are also associated. 
Another mine hole is seen about 150 to 200 yards southeast of the 
one just mentioned. The hill in which they are contained is called the 
Red Hill, in consequence of the deep red colour of the soil. The ore 
is contained in a stratum of rock resembling compact trap. It is about 
two or three feet thick, and dips 30° to 40° to the eastward, parallel to 
the slate. 
In Fishkill, on Mr. Van Wyck's farm, one mile southeast of Johns- 
ville, Mr. Merrick saw a thin vein of quartz in limestone, which con- 
tained galena, and some copper pyrites. 
Blende occurs abundantly with the lead ore at Ancram lead mine. It 
is both yellow and crystalline, brown and compact. It was also seen 
in veins one-quarter to one inch wide in the limestone at Mr. Ward 
Bryan's, and Judge Bockee's lead mines, in North East. It was seen in 
small quantities at most of the lead digging in various parts of Colum- 
bia and Dutchess counties, but more abundant and beautiful at the old 
" silver mines," in Canaan, two miles south of Whiting pond. 
In North-East, on Mr. Lee's farm, about four miles north of Amenia, 
are excavations made some years since in search of silver. They are in 
quartz veins in the talcy slate rock, near the junction of this rock and 
limestone. Pyrites occurs in some abundance there, but no other ore 
was seen. 
In the northeast part of La Grange are numerous excavations, said to 
have been silver mines, from which, according to tradition, large quan- 
tities were obtained in olden times. Mr. Merrick could discover no
