118 GEOLOGICAL SURVEY 
these localities; and as the latter rock is nearly of the same color, it will always require some care 
to distinguish the two, when the limestone is to be converted into lime by burning. 
I have hopes that some handsome slabs for ornamental purposes may be procured here, for I 
found the rock colored by streaks of chlorite and groups of crystals of actinolite. No quarry has 
as yet been opened at any of these localities, notwithstanding the decided advantages they possess, 
in their vicinity to the river. 
This stratum is exposed again, on a branch of Reaburn’s Creek, in a position highly advanta- 
geous for examination. It is associated with soapstone, and passes, as at the other localities, into 
gneiss. About ten feet of the middle of the bed is good limestone; but on each side of this it 
requires care in the selection of the rock for burning. That this care was not always bestowed 
Thad abundant evidence, in the lime burned at this place. A few hundred yards distant an- 
other opening has been made, and an excellent blue limestone procured; but it was covered with 
a thick bed of earth, which added materially to the cost of quarrying. On the opposite side of the 
Creek the beds immediately underlying these, come to the surface; but the lime is so impure as to 
be worthless in an economical point of view. It shows, however, the manner in which the lime- 
rock was formed, and leaves no doubt as to its sedimentary origin; for here, and every where else in 
the State, the rock is stratified. Fig. 25 will give a correct view of the position of the limestone, at 
this locality.

I have no doubt that when lime is used extensively in this and the adjoining Districts, numerous 
localities will be discovered along the strike of this stratum. Simple as the fact is, that the rocks 
of the State have a general direction or strike of about N. 20° to 30° E. it seems to have occurred 
to but few persons to apply it to the tracing out of beds of lime rock, or other useful mineral. 
Lime has been burned here to some extent, in a kiln alike unfavorable to the quality of the lime 
produced, and to the economy of the operation. I shall point out elsewhere the defects of the kilns 
of the State, and give approved plans for such structures. 
Union District. 
The state of the rocks, in Union, renders it peculiarly difficult to point out their precise limits.
