field, and the Sandfly Colliery, which is just beginning to put

 of impure coal 3ft. Gin. to 4ft. thick, which is not worked.

10. Recherche basin. At Moss Glen the seams are 6 to 

 7ft. thick, interspersed with bands. 



At Catamaran are two seams, one from 4ft. to 6ft., the 

 other 7ft. thick. The upper seam is being- worked. 



11. Whale's Head and South Cape Coal-field. Here Meso- 

 zoic seams are exposed on the sea coast, but are not worked.
