50 WARM SPRINGS. 



side. Since then the bore has become considerably 

 deeper, and the water, which now flows from it 

 from a depth of two thousand two hundred 

 and twelve feet, has a temperature of 32°*75 C. 

 (90°-95 E.) The famous well of Grenelle at 

 Paris is still more remarkable for its copious 

 supply of water ; it throws up in twenty-four hours 

 744,490 gallons of water. The water comes from 

 a depth of sixteen hundred and eighty-six feet, 

 and rises through an additonal pipe eighty-six feet 

 more above the surface. 



A well, that was bored fifteen years ago at 

 Bruck near Erlangen, affords an instance of the 

 great pressure of such springs. The water gushes 

 out from it with such force, that when a tube four 

 inches in diameter was fixed to the mouth of the 

 well, the water spouted up to a height of thirty-eight 

 feet ; and when this pipe was changed for a leather 

 hose two inches wide it even threw its jet seventy 

 feet high. 



According to a statement which has been made 

 in the scientific journals, it seems that, in some of 

 the oases of Upper Egypt, the ancient inhabitants 

 of the country used to water their land for the 

 purposes of cultivation by means of bored wells. 

 And, according to the English traveller Wellsted, 

 the people of the province of Oman, on the east 

 coast of Arabia, succeed in giving the richest
