burnt many thoufand Years. It is a very old vaulted 
Building, and in its Walls are a great many Chinks, 
whereto if a Candle be applied, the Fire catches in- 
ftantaneoufly, and runs inftantly wherever the Chinks 
communicate 5 but it may be eafily extinguifhed : 
They have hollow Places in the Houfe fitted to 
their Pots, which they boil without any other 
Fuel ; and inftead of Candles, they ftick Reeds into 
the Ground ; from the Tops whereof, upon apply- 
ing Fire thereto, a white Flame immediately comes 
forth, and continues to burn without confuming the 
Reeds, until they think proper to extinguifh it, by 
putting little Covers over them for that purpofe. 
They burn Lime of the Stones dug hereabouts, 
firft making an Hollow in the Ground, and then 
heaping the Stones on one another. This done, 
on applying Fire to the Hollow, a Flame burfts 
out, and is difperfed at once with a very great 
Crack through the whole Heap of Stones and after 
it has continued burning for three Days, the Lime 
is ready : But Stones placed in this Fire for fetting 
their Pots on never turn to Lime ; which cannot 
be made but by heaping them on one another. The 
Barth and Stone are no farther warm than where 
the Fire reaches : And what feems very well worth 
Oblervation, this Flame of Fire gives neither Smoke 
nor Smell, however great it be. 
About an Enghfh Mile and half from this Place 
there are Wells of white Naphtha y which is ex- 
ceedingly inflammable 5 and though the Flame of 
Naptha affords both Smoke and Smell, it is highly 
probable the perpetual Fire I have been defcribing 
is owing to Naptha , but fo purified, in filtring
