GOULD: STRATIGRAPHY OF THE M"CANX SANDSTONE. 177 



Xo. 1, taken below the sandstone, consists chieiiy of blue shale, 

 with occasional strata of white limestone and red shale, and 

 that the red shale becomes more frequent towards the top ; 

 also, that in No. 2, taken above the sandstone, the blue shale 

 hfts been replaced by the red. In ascending the hills to the 

 west, above section 2, the whole country is red, the blue shale 

 having almost entirely disappeared. The color of the soil in 

 this locality reminds one of Barber or Harper county, Kansas. 



These considerations would seem to indicate that the sand- 

 stone mentioned marks the dividing line from the blue to the 

 red shales, or from the Wellington to the Harper.*" Although 

 red shales are found in the Wellington and Marion (Geuda),+ 

 and even in the Chase, + it is not until the disappearance of the 

 blue shales that the term ''Red Beds" is applicable. 



For this sandstone the provisional name of McCaun sandstone 

 is proposed, from the name of the quarry where the ledge was 

 first studied and which has been most prolific in fossils. This 

 is intended not as a formational name, but simply as the local 

 name for the lower ledge of the Harper formation of the Cimar- 

 ron series. This ledge, so far as I know, has no counterpart in 

 Kansas. The first sandstones of the Harper hard enough to 

 quarry, near the towns of Harper, Spivey, Kingman, and Arling- 

 ton, are nearly 100 feet above the base of the formation. 



The McCann quarry is located on the farm of Mr. T. W. 

 McCann, eight miles west and four miles south of Blackwell, 

 O. T., nineteen miles south of Hunnewell, Kan., on the south- 

 west Cjuarter of section 9, township 20, range 2 west. The 

 nearest railroad station is Nardin, four miles northwest. 



On one trip Mr. White and I were successful in securing a 

 number of invertebrates and portions of the skeleton of a large 

 reptile; also, fossil leaves (ferns) and stems from the sand- 

 stone. Other reptilian bones have been discovered in different 

 parts of the quarry, but most unfortunately they have been 

 ■carried away and lost.
