risma subelegans, A. Topekaensis, Macrodon —, Nautilus occiden-

act most of them have been obtained from the rocks of

he limestones of the Permian have been roapesige'f quarried 
in Kansas from the southern to the northern part of the State, 
and many tons sent off to the market. Some of the rock 
quarried is too sdft for valuable structures, but many very 
excellent quarries have been opened.

southern Kansas. In the counties of Bale Comley, Elk and 
Greenwood, it is the newest rock below the Quaternary. No 
other rocks of later formation than the Permian are found 
here. The PERMIAN of Kansas rests conformably on the 
Coal-measures and there is no decided line of separation between 
the two. Certain strata can be oes together as can certain 
other strata of other formation 
The only marked diftereinns is a abies Passing a certain horizon 
in the ascending series, we find the rocks to be all of a drab, 
buff or cream color and the limestones more impure and break- - 
ing with a rough fracture, and when vertically jointed the angle 
more nearly approaches a right angle, whereas the Coal-measure 
limestones are generally more acutely jointed and the blocks 
are regular rhomboids 
he group of the Pecan Mow NTAINS forms an interesting 
study; the strata are — traced and the scenery afforded is 
very fine and views extensi
