220 FOOTE: SOUTH MAHRATTA COUNTEY. 



in nearly all the trap rocks, only one single specimen of agate was found 

 in this iron-clay. This was part of a small geode which was picked up 

 out of a crumbling mass of iron clay fallen from the roof of the Barah 

 Pir Cave at Talewari. 



This fragment of agate and the presence of pebbles of quartz, 

 gneiss and qaartzite exposed at the bottom of the cave by the action of 

 a small stream which flows through it during the rainy season, are addi- 

 tional evidences in favor of the trappean origin of the upper part of the 

 Gauli iron-clay plateau. The agate speaks for itself, and the pebbles 

 indicate the presence of a small inter- or infra-trappean sedimentary 

 deposit like those of which so many exist between the bottom flows of 

 the Deccan trap, or between the trap and the older underlying rocks. 



The Barah Pir (twelve saints) already mentioned consists of one 



fine large irregularly-shaped chamber measuring

between 45 and 50 yards in greatest length, by 



perhaps 20 in greatest width, and from 10 to 15 feet in height. The 



entrance is large, and faces eastward. 



There is an entire absence of stalactites and stalagmite, and the 

 walled sides show the structure of the rock very well. The rock is a 

 tubulated iron-clay of pale color, and but moderately ferruginous. A 

 small stream which enters the south-western corner of the cave just below 

 the roof, partly through the roof in fact, has washed in a small number 

 of pebbles of quartz, gneiss and quartzite. The cave is in a small hill 

 rising from an extensive, but rugged and uneven, sheet of the iron-clays, 

 to the west of the hamlet of Talewari. 



A small but exceedingly well-marked iron-clay plateau, twenty to 



thirty feet thick, forms an outlier on the top of the
