 The coal is of Carboniferous Limestone age, and is associated with 

 limestone, schists,, sandstones, and conglomerates. The dip of the beds is 

 generally 60° to 70°, and their total thickness may be from 6000 to 10,000 

 feet. The seams average 2*3 feet in thickness ; they rarely exceed 7 ; 

 but some reach 10. The alluvial beds overlying the coal are impreg- 

 nated with mercury; haematite and antimony also occur. (From 

 abstract in Proc. Inst. Civ. Eng. xl. 349.) W. T.
