 a breccia ; dips N. N. W. 85° at first ; then it becomes vertical and at last

 beds together are about, ... ... ... ... ... 30 ft. 



34. Limestone, generally sandy and grey, but sometimes more compact and 

 bluer, and then showing innumerable white lines crossing each other in all 

 directions. It dips N. 70°, ... ... ... ... ... 100 ft. 



35. These several varieties of limestone, viz. shaly and sandy, and blue 

 with white lines, repeat themselves continually as far as the top of the hill, 

 but the rock becomes more and more massive and presents portions of crinoid 

 stems well preserved and petrified into a black spar. Sometimes the rock is 

 flesh-coloured, and then the crinoid stems are lighter in colom*, and weather in 

 relief on the surface of the rock. These are the sections of crinoid stems which 

 have been taken for nummulites by Mr. Vigne and Dr. A. Fleming. 150 ft. 



The strike of the beds of limestone wheels more and more to a N. to S. 

 direction. As we approach the volcanic rocks of the Safapoor, the dip becom- 

 ing more and more westerly. This wheeling of the strike is well shown by 

 the Sketch-Section (Sect. F), where we see the face of the limestone-courses 

 uncovered and exposed, and facing the W. N. W. The thickness of the Weean 

 bed is altogether 649 ft. 



A large fault, well marked by a deep ravine, separates the limestone from the 

 volcanic rocks. It runs N. E. — S. W. At the highest point the limestone is 

 seen to attain, the fault is a mere crack, and the limestone is in contact with 

 the volcanic rocks ; but at the S. W. end of the fault, it widens considerably, 

 and beds of limestone are to be observed on its northern side, applied against 

 the trap and conformable and superior to it. The trap dips S. S. E. 



On the western face of the Safapoor, long beds of well-stratified laterite 

 and ash are conspicuous ; they dip S. with an angle of 40. 



54. Our section rims through the spur of limestone nearest to 

 the lake ; three other spurs, parallel to it, descend towards the 

 village of Paturmoola (see Section F.). They present very won-
