j, . six-inch seam marked (d) is granular, like a mass of consolidated coal-dust. 
IS feebly lustrous on some points of the surface. Soft portions dug into with a 
e or hammer take a bright black-lead lustre. It is, in fact, a sort of very earthy 
^ acr lead, with occasional fragments of a silky vegetable charcoal. It is interesting as 
owiug one of the stages in the alteration jjroduced by the intrusive rock. It gives a 
^top-black jjowder, and lias a specific gravity of 1'551.

, The uppermost visible poi’tion of the Daintree Seam (forty- three inches in 
c ness) is in almost immediate contact with the overlying dolerite, and has, conse- 
thr extreme effects of the heat, having been rendered columnar 
columns having a transverse section of from half-an-inch to three 
diameter. The coal has been converted into a hard stony coke. It brightens 
OTo knife to a pale black-lead lustre. The powder is ink-black. Its specific 
giavity is 1-779. ^ ^
