St. Louis has a well 3,147 feet deep.
Louisville has a three-inch well, 2,086 feet deep, with a capacity same as the Grenelle well.
There have been nine artesian wells successfully bored in Cincinnati, a description of which will be found on [page 107].
Charleston, South Carolina, has an artesian well 1,970 feet deep, from which pure soft water, of 90° temperature, flows ninety feet above the surface. It has five inch tubing on top and two and three-fourths inch diameter at bottom. The cost was $2,500.00, and the time required in sinking was a little more than a year. There is also an artesian well, in the same city, 1,250 feet deep, which discharges 25,000 gallons a day, of water, at a temperature of eighty-eight degrees, strongly impregnated with sodium and magnesium.
The desert of Sahara has a number of well borings, some yielding as high as 1,500,000 gallons daily. The depth varies from 130 to 400 feet, and temperature 70 to 77 degrees.
The Ohio State authorities undertook to supply the capital by an artesian well. After two failures, in attempting to tube out the quicksand, they succeeded (in November, 1857) in piercing through the rock, and at a depth of 149 feet a vein of water was struck that continued to wash away the borings for nearly 100 feet below. On the 1st of October, 1870, a depth of 2,775 feet was reached, but no flowing water obtained, when the undertaking was abandoned for want of an appropriation.
The record of the boring is tabulated as follows:
| SYSTEM. | GROUP. | STRATA. | THICKNESS. | ||
| FEET. | |||||
| 1 | Drift. | Alluvial drift. | Clay, sand, and gravel. | 123 | |
| 2 | Devonian. | { | Base of Hamilton. | Dark bituminous shale. | 15 |

| 4 | Silurian. | { | Clinton. | Red, brown, and gray shales and marls. | 162 |

Temperature of well at bottom, 88 degrees, being uniform for 90 feet, at 53 degrees, will make an increase of one degree for every additional 71 feet. It was the opinion of Prof. Newberry, that, if water was successfully struck, it would be of a saline character.
