TU50ADHEAD — CARBONIF. ROCKS OF EASTERN KANSAS. 483 



JietJiipUcata^ which, together with other fossils found in the same 

 stratum, has its interior lined with clear crystallized calcite. Just 

 a little higher is a limestone abounding in Fusulina cylindrica. 

 These beds correspond to Nos. io8 to ii3 of Mo. Section [Mo. 

 Geol. Rep. 1S72, Pt. 2, p. 94]. 



Near Olathe are beds near this horizon, or probably a little 

 higher but still belonging to the upper coal measures. 



In the eastern part of Miami county the strata are equivalent to 

 those of Cass and Jackson counties. Mo. 



The productive coal measures lie chiefly in the eastern tier of 

 counties south of Miami county, and include valuable coal beds. 

 In the country southwest fi'om Paola to Wilson county only thin 

 coal seams are occasionally worked, with no profitable result. 

 The last of any consequence in going westward is in the sonth- 

 west part of Woodson county and less than one foot in thickness. 



A general section of the rocks seen in the western part of Mia- 

 mi and eastern part of Franklin on the Marais des Cygnes river 

 is as follows : 



1. 22 feet irregularly bedded gray limestone, breaking into small frag- 



ments on exposure, contains Productus splendens, P. punctatus, 

 Spirifer cameraius, Syntrilasma hetniplicata, and Myalina sub- 

 quadrata — the interior of fossils often crystallized calcite. 



2. 86 feet chiefly shales, the lower 30 feet thick layers of clay shales, with 



beds of clay ironstone, and a bed of red shale near upper part. 



3. 20 feet gray limestone; has minute calcite veins. 



4. 20 feet or more of clay shales with yellow ochre concretions. 



This section includes (the upper on hilltops, the lower in the 

 valleys) the rocks from Ossawattomie to Garnett, for over 25 

 miles. Near Lane and Greeley the upper is surmounted by a 

 good building-stone of oolitic limestone, which when polished is 

 sometimes shipped oft' under the name of ''coralline marble." But 

 the supposed corals are only oolitic forms, giving beauty under 

 magnifying power, but otherwise appears like a dull dark gray. 

 It very much resembles the Kansas City oolite, but is probably a 

 different stratum higher in the series. The exact geological posi- 

 tion of these beds I have not yet been able to correllate with Mis- 

 souri strata, but they belong to the upper coal measures near the 

 horizon of the rocks at Weston, Platte county. 



Passing westwardly from Miami and Anderson counties we do 

 not find our well known Missouri strata, but they seem to be
