GEOLOGY. 



It is underlaid throughout by nearly horizontal non-cal- 

 careous strata of sand and clay in various mixtures, usually 

 pinkish or yellowish in color, several hundred feet thick, 

 and in age probably not older than Pliocene. On top of 

 these in many places is a few feet of essentially homogen-
