Cannel Coal, Blossburg. 



This combustible has a dead black colour, with a 

 light tinge of lead grey ; is compact, clean and dense ; 

 breaks with a large conchoidal fracture ; cuts with a 

 ' knife, and receives a polish. This property combined 

 with its waxy tenacity, enables it to be manufactured 

 into various-shaped ornaments. In its nature it is per- 

 fectly homogeneous, burns with difficulty, giving off little 

 bitumen, and a coke slightly deformed. Its powder is 

 brown. The residuum or ash, after incineration, con- 

 tains no lime.

Iron Ore, from Morris's run, Blossburg. 



The specimen of iron ore before us, appears to be a 

 portion of a large globe or kidney. It is intersected by 

 cavities, upon the sides of which are found groups of 

 small rhomboidal crystals of carbonate of iron. Its frac- 

 ture is uneven, conchoidal, and has a dark black colour, 

 giving a greyish white powder. When cold, does not 

 effervesce, but when aided by a gentle heat, the action 

 is lively. There is a precipitate of carbonaceous matter 

 to which the colour of the mass may be attributed. An 

 abundant precipitate of the oxide of iron is thrown down 

 by the addition of an alkali. 



Kidney Ore ^ from Blossburg. 



In form and colour this ore differs from the preced- 

 ing. Its shape is that of a rounded lenticular mass, and 

 is covered by a thin coating of bituminous shale. Its
