Show TO EXPLORE EARTH'S CRUST. Shaft to Be 8unk as Far as Possible to Verify the Increase of Heat. Earth exploration Ih proposed by M. Cnmlllo FInmmnrion, who suggests n, deep shaft as far as posnlblo into the bowols of tho earth. Tho maximum "depth hitherto attained below tho neun level of tho globe's surfaco is about C.C00 feet Ho remarks that tho IncrenBO of the earth's Internal heat varies In a graduated manner, according accord-ing to tho roglons. Its avorago In-crcaso In-crcaso 1b ono degreo centigrade to ovcry 108 feet Hut whatever tbo pro-portion pro-portion thoro in at n certain depth an inoxhnustlblo sourco of heat that might bo distributed and applied. Ono of tho first results of tho sinking sink-ing of tho shaft would bo to vorlfy this increase of heat as you go far-tho far-tho into tho earth. Tho second would bo tho exploration of this unknown un-known soil. Who knows what geological geologi-cal nnd palcontologlcal curiosltlos will not como to light, iron mines, copper mines, precious metals, veins at gold, platinum, silver, radium, etc? M. FInmmnrion thinks that a shaft 200 or 300 yards In diameter would bo needed. It would hnvo to bo cased with a ring of mnsslvo enst Iron. The enrth excavated might bo taken to tho Ben. Tho lands aB well as cor-tain cor-tain plalnB of Dolglum, Holland, nnd Houmanla would bo flultablo for excavating ex-cavating purposes. M. Flnmmarlon calculates that tho tomporaturo ot boiling water would bo roachod at a depth of about fifteen furlongs, but It would be neccBsary to go much doopor ln ordor thoroughly to investigate investi-gate tho oarth'3 crust. |
