MYSTERIES OF HIDDEN HEAT

Vast stores of heal and power He. bidden in the bowels of the earth, waiting lo lie tapped. We could do wit lionl. coal and oil could we hut develop (lie heat resources of the earth. And in .so doing we should probably find new chemicals and minerals of Ihe grealest cable to the world’s commerce, Already some use is being made of the internal beat of (lie cartli in volcanic regions of Italy, where the steam issuing from the ground is trapped and devoted to various uses. II is suggested that bores should be sunk to admit water, which would, be converted into steam, ami could then be utilised for ineebaiiieal purposes. Kxea\ai ion methods and machinery have been improved so much of recent vesrs that it may be possible lo sink Miicli bores and shafts to a depth of lit) miles. At present the deepest, well ever bored is a bole six inches in diiiini ler mi a farm in America. It lias Ijci' 11 driven to a depth of 7,n7!M’1., or nearly a mile aial n-Imlf. The deepest mine shaft is at Mono Vellio, Brazil, which descends about a mile and a fifth. \s one experl points nil, we have succeeded in scratching only Hie earth's crust.
