''Massive glistening hard sandstone, resembling Hawkesbury Sand- 
stone of New South' Wales, contains oasts of plants, and at 
base of bed, where it passes into a fine conglomerate, as near 
the Pilot Station, St. Lawrence, it shows casts of Spirifers and 
Martinia suhmdiata, a shell in New South Wales especially 
characteristic of the Permo-Carboniferous Formation in which 
occur the valuable Greta Coal Measures. Part, therefore, of 
this bed, and portion of the underlying strata, pmobably are of 
Permo-Carboniferous age, and may contain the Greta Coal Seams 
Hard shales, dark grey and light grey, with thin bauds of ironstone

5. These strata can be prospected by means of a number of shallow shafts. 
6. Strata usually associated with the Greta Coal Measures. 
Since the above was wTitten Mr. W. II. Bands has completed a survey and made 
a report on the Styx Coal Field. The report contains a mass of valuable information 
regarding the coal-seams, but throws little light on the age of the measures. Mr. Bands 
says : “ There is no evidence to show whether they (the Coal Measures) are the equivalents 
of the Ipswich or the Burrum Beds. All that can be said with certainty is that they are 
Mesozoic. They are older than the Upper Cretaceous Desert Sandstone, by which they
