present no trace of erosion, nor are there any sigus that the sandstone 



was deposited in these irregular hollows. The limestone here seems 



irregular, but thinner than in most other places, not being mpre than 



from 20 to 50 feet in thickness. On its inner side some greenish 



clays are in junction with it in the stream bed (c),

 red clays occur in their natural place next to the limestone. Further 

 up the stream, contorted and obscure masses of gypsum and greenish 

 clay, the latter often wedged apparently among the former, are seen 

 filling up the interior portion of the range. At one spot where the 

 stream crosses a mass of the gypsum, the latter is so deeply eaten into 

 that it becomes impracticable to keep to the river bed, and here a small

 the gypsum (f) is plainly stratified, vertical below, but bent over above 

 as shown in the figure, and is in close contact with 35 feet of greenish
