Artesien Wells.

As this subject IS becoming generally in teresting, We make the following extracts f'v"@ r~rnnhlat nn the snhiert in reoard to the artesian well in Louisville, Ky. The water is recommended for the cure of dys- pepSia, costiveness, derangements of the liver, nervous diseases, scrofula, etc:

 This work was commenced in April, 1857, from the bottom of one of the wells of the factory, that has depth of twenty feet; the boring tools employed made hole five inches in diameter to the depth of seventy-siX feet from the surface; the bor- ing was now reduced to three inches and thus continued to the bottom of the well, depth of two thousand and eightv-siX feet. The flow of water is three hundred and thirty thousand gallons in twenty-four hours, and the elevation above the surface one hundred and seventy feet.
 The rock struck, which geologically be- longs to the ' Devonian series,'' is for thir- l ty-eight feet shell limestone, then for forty | feet coraine limestone; at which depth the upper silurian is reached Without being able to make out with any degree of certain ty, the amount of upper silurian passed through, we suppose it to be over one thou sand, two hundred feet At the depth of one thousand, six hundred feet a sand rock was reached, doubtless of the lower silurian, and ninety-seven feet deeper was encoun- tered the first stream of water which leach- ed the surface. This flowed out abundant. ly and with much force. The quantity not being sufficient, the boring was continued Alter this, It was unnecessary to use the bucket to take out the material detached by the borer, the force of the water bringing up the fragments very readily The water increased in quantity in going deeper, the increase being more marked at one thou sand, eight hundred and seventy-nine feet, and still more at one thousand nine hun | dred feet, when pieces of rock weighing an ounce or two came up with the water. The water increased every ten or twenty feet to the deapth of two thousand and thirty-six | was encountered six feet in thickness. After which the sand rock reappeared, and for the next fifty feet there was no increase of water.

 At the urgent request of many citizens of Louisville, the boring was now stopped to | give a fair test of the medical virtues of the water that was pouring forth at the rate of two hundred and thirty gallons per minute, or about three hundred and thirty thousand gallons in twentyfour hours. The water by its pressure lises in pipes one hundred and seventy feet above the surface. The boring was accomplished in sixteen months, and the depth reached is two thousand and el8hty-six feet, which depth we can better conceive of by referring to corresponding nights, as represented by spires in our city; imagine seven such spires as that of the Catholic Cathedral piled on each other- In order to conduct the water to the surface and prevent its passing off into the gravel beds below, tube five inches ill diameter leads from the surface to the rock, depth ot Seventy-siX feet, into which 1t is driven with collar of vulcanized gum elastic around it. No tubing is found necessary for any other part of the boring.
 When the size of the bore (three inches in diameter, and its depth are considered the flow of water from the we'll is uneouall- ed by any other artesian well yet construct ed that flows above the surface, for although the Grenelle we'll at Paris delivers six hum dred thousand gallons in twenty-four hours, It has at the bottom an area six times as great as the Dupont we'll, and few hun dred feet up seven times as great. A cor responding diameter 10 Dupont's we'll, would, according to just and reasonable calculations, furnish about two millions gal Ions in twenty four hours; also, the eleva- tion of the water above the surface IS greater than that of any other Artesian we'll, and only exceeded in depth by the St. Lonis well, and that to an extent of but one hundred and thirteen feet.
