The synopsis of boring is condensed as follows:
July 24, 1880.—The contractor, John J. Pfeffer, drove a 6-inch iron tube with a heavy sinker, a few feet at a time, through 123 feet of drift, into limestone. A sand-pump was used to remove the loose formation. This portion was completed August 2d, 11 A. M.
August 2.—Commenced drilling a 4½-inch hole through the stone formation at an average rate of 33 feet per 24 hours, and continued to a depth of 425 feet, when the diameter of the hole was reduced to 4⅜ inches. The drilling was then continued, at the rate of 29 feet per 24 hours, until the 28th of August, when the socket pulled out of pole attached to sinker at bottom of well, and at the same moment the top pole, attached to chain on drilling beam, broke and fell into the well along-side of the sinker. This accident was repaired September 7th, and drilling resumed, at rate of 20 feet per 24 hours, until a depth of 1,025 feet was reached, October 11, 1880, when the drill broke. Resumed work, at rate of 12 feet per 24 hours, until November 5, 1880, when a depth of 1,265 feet was reached. At the depth of 1,225 feet, the well was tested by sinking a 4-inch pipe into the well with a bag at lower end to fit tightly into the 4½-inch bore. When the pipe reached a depth of 15 feet below the 6-inch tubing, the water flowed over the top of the pipe at surface, showing a leak around the bottom of the pipe where it was bedded in the rock.
November 8th.—Tested well, and found a pressure of 30 lbs. per square inch, and a flow of 90 gallons of water per minute.
February 17, 1881.—When testing well No. 2, the gauge was placed on this one, which showed only 15 lbs. The bore was then increased to 4½ inches, and drilling continued to a depth of 1,360 feet, the last 40 feet being only 3½ inches in diameter. The additional 125 feet was through alternate formations of sand and limestone; the last 10 feet through a hard flinty formation. Boring into this last formation increased the pressure to 41 lbs., and the flow to 200,000 gallons per day. The outlay of the two wells is placed at $8,000.

Prof. Newberry is of the opinion that soft water is improbable in these deep rocks.
