that strong brines can also be found in sandrocks much nearer the surface, as shown by the following interesting facts. Young's salt well, from
which salt has been manufactured for several years, situated one mile
north of Newburg, Noble county, obtains its brine in a white sandrock,
199 feet below the surface. In the Eastwood and Parker well on the
Isaac Davis farm, in Olive township, Noble county, a very large flow of
strong brine was obtained in a ~white sandrock 227 feet below the surface.
The same sandrock yields oil.
In the Diamond oil well on David McKee's farm at Newburg, Noble
county, brine was struck in a white sandrock 236 feet from the surface.
Brine was also found in the same well in a heavy white sandrock 107 feet
below the one above mentioned. In David McKee's well, No. 2, brine
was found in a white sandrock 347 feet below the surface.
On the flats below Maxburg, Aurelius township, Washington county,
abundant brine is found in a sandrock 308 below the surface. It will
probably be found that the saliferous rocks of the Upper Duck creek valley will group themselves into three distinct horizons-two upper ones
comparatively near the surface, and the other one, underlying the coal
measure rocks. The brines, in strength and quality, will hereafter be
studied. A little salt for local use has been made in the Upper Duck
creek valley for many years, but the difficulty of transportation has prevented its exportation. The difficulty will soon be obviated by the Marietta and Pittsburg Railroad, which passes up the valley. Coal mines
affording cheap fuel are found in all the hills bordering Duck creek, from
Salem, Washington county, to Soak'em, Noble county. The Duck creek
valley could easily supply the West with salt.
PRODUCTION OF IRON IN THE SECOND GEOLOGICAL DISTRICT.
Furnaces line the iron ore belt of the lower coal measures, from Logan,
Hocking county, on the north, to the Ohio river on the south. This district is universally known as the " Hanging Rock Iron District," and has
long been famous for the remarkably fine iron it produces. The ores
hitherto used have been chiefly the native ores of the hydrated sesquioxide or limonite group. Of late mixtures of Missouri and Lake'
Superior ores have been introduced in a few stone coal furnaces. Charcoal is the principal fuel.
The following is a list of the furnaces:
