Mound City Well, Linn County. 
No. 1. 
There is a salt well on the property of Doctor Trego, at Mound 
City. This well, which is 340 feet deep, was bored with an eight- 
inch drill. The brine comes into the well at a depth of 210 feet, 
and is forced out at the top of the well by the gas which accom- 
panies it. Since 1886, when the well was bored as a prospect 
hole, the water has been flowing at the rate of about forty gallons 
per hour. The brine is used locally for medicinal purposes. This 
water yields 1020 grains of mineral matter to the gallon, upon 
evaporation. Of this, 1000 grains is common salt. The reac- 
tion of the water is slightly alkaline. Besides the salt, it con- 
tains small quantities of sodium carbonate, calcium carbonate, 
and magnesium carbonate, as well as traces of sulfates, bromids, 
and iodids. 
No. 2. 
Another salt well, about 400 feet from No. 1, on the property 
of Robert Fleming, has been recently bored, to the depth of 144 
feet, and it has about the same flow as the former. This, as 
well as the former well, showed thirty-five pounds per square 
inch of gas pressure. The water is a brine, not as salt as No.1, 
however. It contains 719 grains of mineral matter per gallon, 
and of this, 686 grains is common salt. The other ingredients 
are carbonates of iron, calcium, magnesium, and sodium, rather 
more in proportion than No. 1.
