We boiled this second boiling to about a pint and a half, then poured it gently off into a bason, leaving the scum and sediment behind; after it has stood about a quarter of an hour to settle, we again poured it into earthen soup plates, set them in a cool place till next morning, at which time the sides and bottoms of the plates were beautifully covered with crystals of Salt-petre sprung up like large blades of grass, being in quantity about a quarter of a pound.
