This section corresponds, with a variation of only a few feet, with 
that seen below Rushville as far as exposed, that is to the conglomer- 
ate II, below which it agrees essentially with the Licking county ex- 
posures. The calcareous nodules and surrounding shale contain a 
rich fauna exactly equivalent to the Moot’s run horizon (No. 13.) being 
characterized by Spirifer marionensis^ Sireblopteria fi^agilis, Pterino-- 
pecte?i cariniferus, etc. The freestone is somewhat contracted and less 
fossiliferous and shows premonitory symptoms of its decline further 
north-east. Further west in Richland and Knox counties one or both 
of the conglomerates are thickened at the expense of the remaining 
strata.
