Chrome is a white metal, inclining to 

 grey, very brittle, and crystallizable at an 

 elevated temperature in feathered fila- 

 ments on the surface. 



The minerals to be found in England

 vitriol and allum are found in considera- 

 ble quantities ; our canal coal approaches 

 nearly to the beauty of jet, and even our 

 common coal fire for firing is of a superior 

 nature. The English earth and gravel 

 are of the best quality; and we have stone,, 

 slates, flags, and other fossils necessary 

 for building in great abundance. Tin is 

 another article in which England, from 

 the time of the Phenicians had always had 

 the pre-eminence- The county of Corn- 

 wall alone produces more than all the 

 world besides. Our lead ore is richer 

 than in other countries, runs more fluently

 pense in working, and is when wrought 

 very fine and ductile* Our black lead or 

 wadd, found in Cumberland, is a mineral
