A great thickness of paper-shales containing paraffin occurs near 

 the river Golabara • these extend over 30 square miles of country. 

 Small beds of clay with rock-salt are also found : the whole is said 

 to resemble the paraffin and salt districts of Galicia. The paraffin 

 shale is free from bituminous impurities. It contains : —
