This concludes the references to the distribution of the coal-measures 

 in this extensive field. The number of distinct seams is small, and for 

 such an area there is not an abundance of coal. The lateral extension,

This title, derived from the name of the only inhabited village within 

 the limit of the coal measures that it applies to, defines an independent 

 tract of Barakars lying south of the main area, and east of the Hestho 

 river in the Korea State. 



The superficial area is 48 square miles, and it embraces some very 

 wild country densely packed with bamboo jungle,
