Baku, a Russian port on the Caspian Sea, in a district so impregnated and saturated in parts with petroleum that by digging in the soil wells are formed, in some cases so gushing as to overflow in streams, which wells, reckoned by hundreds, are connected by pipes with refineries in the town; a district which, from the spontaneous ignition of the petroleum, was long ago a centre of attraction to the Parsees or fire-worshippers of the East, and resorted to by them as holy ground.
Population (circa 1900) given as 107,000.
Definition taken from The Nuttall Encyclopædia, edited by the Reverend James Wood (1907)
