THE SAGAR DISTRICT. 65 



hill must be added to the measurement just given, for instance the well 

 on the edge of the hill at the mint of Sdgar. 



The surface of the slope, where this well was opened, was thickly 

 strewed with large black wacken boulders, and these continued for some 

 little depth below the surface, enveloped in a dark reddish rusty ferruginous 

 wacke clay, succeeded by a bed, ten or twelve feet thick, of large angular 

 pieces of a deep chocolate coloured basaltic hornstone, underlied by a bed 

 of yellow clay, which yellow clay or lithomarge formed indeed, a sort of 

 coating or lacing to the superincumbent hornstone. To these followed a 

 stratum of limestone, similar to that of the cantonment wells of Sdgar 

 resting upon the softer amygdaloids, which I have numbered : In these 

 amygdaloids the water presented itself at a distance of forty-seven feet 

 from the surface. 



The following are the strata met with in a well in the cantonment of 

 Sdgar on a swell of trap.
