The Elkhart Wells Section. — These wells are one mile southeast of Elk- 

 hart and thirteen miles south of Palestine. The surrounding country is very 

 flat, and is fully one hundred feet below the railroad level at Palestine. Be- 

 tween the two localities were seen the greensand bed with its underlying 

 sands and clays. Six miles from Palestine the descent begins, and beyond 

 that the hills are rare, and seldom rise high enough to be capped with the 

 yellow indurated greensand. The following section is made from the sur- 

 rounding exposures and the wells at that place.
