One-half mile of section 1 (See Hi, Fig. 11.) only a thin 

 layer of gravel is found. At this place it is directly overlaid 

 with loess full of concretions. The sands and clays which over- 

 lie it in the other sections are absent ; but scarcely a quarter of 

 a mile west on the same hill gravels and sands rise 35 feet above 

 the plain (See iv, Fig. 11.) and about 70 feet above the river. 

 The gravel here does not appear to be in any particular bed, 

 although it is more abundant near the base of the hill. At times 

 it is found in lenticular beds between the sands. Brick red 

 sands were seen at a height of 35 feet. The pebbles in many 

 places are cemented together, forming large masses of con- 

 glomerates. Through the sands are plates of iron as much as 

 3 inches thick. The old surface was visible but not very well 

 defined. 



One mile west of section 1, at v, Fig. 11, the following 

 strata were observed :
