Southwest of Holmesville two and a half miles, on the west 

 bank of the river, there is a long escarpment of very excellent 

 limestone, that in early days was quarried and transported by 

 wagons as far as Lincoln, to be used for building purposes. 

 It occurs in good workable beds and breaks across the bedding 

 as well as with it. When the stone is taken from the quarry it 

 is easily cut with saw or plain, but upon exposure it becomes 

 very much harder. When large dry blocks are struck with a 

 hammer they have a metallic ring. It has been called magne- 

 sian limestone, and resembles very much the so-called magne- 

 sian limestones, that have been quarried from the Kansas Per- 

 mian for many years.

The position of this section in reference to Holmesville is 

 questionable. Levels were not run but there is some evidence 

 that it occupies a place lower than the Holmesville bed. Possi- 

 bly it may represent the Holmesville section in part ; the differ- 

 ences in the strata being accounted for by a difference in sedi- 

 mentation. Only a few fossils were found.
