primitive ; ; nor has a particle of bituminous coal ever beer 
found in the same formation, or connected in ary manner with 
the anthracite.* 
It may be considered as a pretty general fact, that no other 
coal has been discovered, or is likely to o be-discovered, in the 
scot, except anthracite ; and also, that in those places where 
~ it has been found, its geological associations are decidedly 
#anshion : at least, I know of but one solitary exception, 
and this is in the vicinity of Hadley, on the Connecticut 
river, where small veins of bituminous coal have been dis- 
covered. But this only confirms my remark ; as the rocks 
in which it has been traced are purely secondary, or what 
Jamieson characterizes as of the floetz trap formation. To il- 
lustrate these positions, let us commence with the Pennsylva- 
nia anthracite, on the Susquehanna, the Schuylkill, and the 
Lehigh: here its geological situation and localities are deci- 
ly transition. whole of the extensive coal formation, 
commencing at Rhode-Island and extending to Providence, 
Worcester, and Lancaster, in Massachusetts, and even te 
Keene ‘in New-Hampshire, i is also unequivocally transition, 
nearly connected with the great primitive ranges. Many 
other localities may be pointed out in tracing it to the east- 
ward, but I know of none where the indications of this co 
are so oe as at Thomastown, in Maine, where the anthra- 
cite is seen cropping out on the surface, with all its associating 
minerals, such as gray wacke, gra wncite slate, and transi- 
‘tion Hiiestobe: yet, with such indications of c oal, and under 
such favourable circumstances, as vicinity to mec carriage; 
{ do not find that any attempt to explore it has been as yet 
e. 
As there is no situation where it would be more desirable 
to find coal than the banks of the North River, many at- 
‘tempts have been made to discover it, but without success; 
nor could any other coal but anthracite be expected by those 
who have any geological knowledge. In illustration of this 
q 
opinion, I may mention that small veins of coal have been .
