The brown spar at the " White Mine," about one mile east of the 
western summit of Anthony's Nose, contains magnetic oxide of iron 
disseminated. 
A locahty of magnetic oxide of iron occurs on Mr. Tilly Foster's 
farm, two and a half miles southeast from Putnam Court House. 
The ore forms a large part of a hill about one hundred yards long, 
ten to forty feet broad, and elevated twenty to thirty feet above the 
ground adjoining. Some hundreds, perhaps thousands of tons of ore 
can be easily procured at this place, without digging below the level of 
the hill. 
Another ore bed w^s discovered some years ago about half a mile 
southwest of the preceding, on land belonging to the Misses Fowler. 
Some tons were dug out, but I do not know whether any has been 
smelted. 
The Simewog vein passes through Simewog hill, and was traced one 
and a half miles SS W on Mr. Jedediah Wood's farm, and it is supposed 
to continue still farther SSW, as ore has been dug in that direction, 
about one mile SSW from Mr. Wood's house. 
This vein was formerly extensively worked at Simewog hill, and the 
mine is called Townsend's mine. 
This mine was the first known and first w^orked in this part of the 
country. The ore w^as carted to great distances and shipped on the 
North river, and some of the towns on Long Island Sound, to various 
parts of the country. The largest portion of the ore was carried to 
Danbury in Connecticut, and was there an article of traffic. It has not 
been wrought for twenty or thirty years, in consequence of other beds 
having been found in more convenient locations for smelting and trans- 
port. Fifty thousand tons of ore, at least, have been taken from this 
mine, estimating four tons to the cubic yard; and 100,000 tons more 
may probably be taken from the vein in Simewog hill, without going be- 
low the level of the small stream which flows across the ore bed. 
Should it ever be necessary to obtain this ore in quantity, (as is proba- 
ble, from the prospect of the New-York and Albany rail-road pass- 
ing up the valley on the east side of the hill,) at least 1,000,000 
tons may be calculated on, above the water level of the Croton river, 
which flows along the base of the hill, and free from the expense of 
drainage, by driving an adit level from the level of the Croton, a 
distance of 300 or 400 yards to intersect the vein. This vein of
