In regard to the identity of the Coal-measures of Tino, 
with the regular Coal-measures (overlying the Millstone gr) 
of Ohio, Pennsylvania, Kentucky, and other neighboring states, 
it is only necessary to again quote Lesquereux, who. has given 
especial attention to tracing out the parallelism of the subordi 
nate beds at distantly separated localities in the coal fields of the 
Middle and Western States. On this point he says, (ne 
[2], xxx, 367,) “Such is, nevertheless, the uniformity 
distribution of the strata of our coal- basins, that a vier 
in Western Illinois or Western Kentucky, or in any pa 
coal-fields in these States, will prove comparatively tenia ae :

section made in the coal-fields of Pennsylvania or Ohio.” Now
