burnt can be a6ted upon only by the nitrous acid ; but not 

 until the folution has been continued a confiderable time in 

 heat, and then it lofes nearly a third of its weight. When 

 water is poured on the pure folution, it becomes a little 

 muddy; and when it is fuflered to evaporate entirely, a 

 bitter fait exceedingly eafy to be diffolved is obtained. The 

 •undiffolved earth, fufed in a ftrong fire, is converted into a 

 brown flag. The frefh earth remains in water unchanged; 

 and when it has been mixed with it by fhaking and ftirring, 

 it falls again to the bottom, lofes its eohefion, and cannot 

 be again ufed. The earth, after being burnt, imbihes a large 

 quan :ty of water, throws out abundance of air bubbles, 

 and becomes foft. 



The peafants of the village of Kiltfchik dig up a fufficient 

 quantity of this earth, for which they pay a certain fum tb 

 the monaftery, and then cut it into bowls for tobacco pipes. 

 For the nioit part, however, they prefs the earth, while yet

 them is covered with a hard yellowifh cruft, they place the 

 whole quantity of bowls in a heated baker's'oven, and let 

 them remain there till it is entirely cooled. They then boil 

 them for an hour in milk ; and when they are taken from it," 

 tbev rub them with Bifchik Kuirvghi (equifetum) common

 is at length completely effected by means of a piece of foft

When the bowis have been prepared in this manner, and 

 fent to Conftantinople for fale, they are dyed there of dif- 

 ferent colours, partly by being boiled in wax or oil. The 

 bell; mixture, however, is dragon's blood and nut-oil ; for. 

 when the bowls have been well foaked in this mixture and 

 penetrated by it, they acquire, in a fhort time, a moft 

 beautiful dark- red dye. The Turks, however., jn gencial are
