DEEP BORING.

A deep artesian well is being bored at Festb, and has reached a depth of nearly 1000 metres, over 3300 feet. The work is undertaken by the Brothers Zsigmondy, partially at the,expense of the city, which has granted £"40,000 for the purpose, with the intention of obtaining an unlimited supply of warm water for the municipal establishments and public baths. A temperature of 161 deg. Fan. is shown by the water at present issuing from the well, and the work will be prosecuted until water of 178 deg. is obtained. About 175,000 gallons of warm water steam out daily, rising to a height of 35 feet. This amount will not only supply the wants of the city, but convert the surrounding region into a tropical garden. Since last June the boring had penetrated through 200 feet of dolomite. The preceding strata have supplied a number of interesting facts to the geologist, which; have been recorded from time to time in the Academy of Sciences. Among some of the ingenious engineering devices invented during the course of the borings are especially noteworthy the arrangements for driving in nails at the enormous depth mentioned above, for pulling up broken tubes, and a mechanical apparatus by meanß of which the water rising from the well is used as a motive power for driving the drills.—Lancet.
