Below 128 feet, at which saltwater was met with, there occurs 

 a hard red slate containing mica. 



Mr. Lattorff writes, July 24, 1880, that the rainfall during 

 the four seasons he has been at Whittata has fallen between 

 four and seven inches per annum ; that the rain does penetrate 

 the soil for more than four feet on the average, except in 

 favoured places, where we have found damp ground to seven 

 feet, or when saltwater lies near the surface. This is the 

 result arrived at from observations made in the course of trial 

 sinkings and excavating dams to the number of about forty.
