According to Prof. A. W. Jones of Salina—to whom the writer 
is indebted for many favors—at about the level of the river is a 
stratum of gypsum about 10 feet below the base of the limestone— 
No. 3 of the above section. A shaft sent to the depth of 25 feet is 
reported to have penetrated principally gypsum. Professor Cragin 
has briefly described this locality, noting the layer with abundant 
Myalinas, which he called M. perniana, and named the gypsum 
stratum the Greeley gypsum!. The writer agrees with Professor 
Cragin in regarding the fossiliferous limestones in this quarry as 
near the top of the Marion formation. 
No other outcrops of the Marion were studied in the valley of the 
Smoky Hill river, and these limestones according to Professor Jones 
do not extend much farther up the river valley.2 the south- 
eastern part of Saline county and southwestern portion of Dickin- 
son below the base of the Cretaceous are variously colored argilla- 
ceous Shales which have been referred to the Wellington. Farther

most southerly appearanve of these limestones and shales on the Smoky is about 
four and a half miles south of Salina.’’
