(^2 IOWA ACAIJF.MV OF SCI KN CKS. 



(/),) The trend of the fold at Jones' l^oint is north 50 de- 

 grees, eiist HO degrees, approximately parallel with the 

 northern border of the carboniferous, viz: a line passing 

 through Dunlap, Iowa, and Rockport, Omaha and Ashland, 

 Nebraska. Also with several exposures in Nebraska and 

 Iowa which may be found to be along the higher anticlinal, 

 viz: Roca, Bennett, Weeping Water, Glenwood, Malvern 

 Macedonia, etc. 



(6.) Paleontological evidence seems to coincide with the 

 conclusions from stratigraphy. Of the more than one hun- 

 dred species, listed by Meek as found in eastern Nebraska, 

 twenty are found north the steep fold at Jones' Point and not 

 south; forty-seven are found south which are not north, and 

 thirty-five are found on both sides of the line.
