SANDSTONE SERIES. 17 



4. Gre3risli white sandstone, purplish in places, slightly argillaceous, varying 



somewhat in texture, being coarse in patches, though generally fine. 4 

 This is a good building stone used by the natives for temples, and large 

 slabs are cut for gravestones. In another quarry, this rock is softer, 

 much coarser, and more felspathie, but still quarried for building 

 purposes. 



5. Grit with hard ferruginous bands ; no section seen, minimum thickness. 10 



This bed is probably thicker and may include other bauds. 



6. Fine yellow (or deep buff) compact shale, becoming red near the surface. 3 



A fine building stone used for ornamental purposes, 



7. Grit and conglomerate, no section seen ; it probably resembles the next. 50 



8. Coarse ferruginous grit and conglomerate with irregular ferruginous bands 



as in 3 and 5 ; these bands are very hard,* and are evidently 

 not due to original deposition, as they cross the bedding, and in 

 one case a band was seen in the form of an oval. Conglomerate 

 beds are dispersed throughout the rook. In one quarry there is seen 

 a thickness of ... ... ... ... .., 25 



9. Pine brown argillaceous sandstone, peculiarly laminated in places, with 



curved joints, nearly in the direction of the stratification, which con- 

 tain a black mineralf (sesquioxide of manganese?). This bed is 

 probably local. ... ... ... ... ... 6 



10. Fine buff-coloured compact shale, much resembling 6, very similar to 



the bed containing Estheria at Mangli between Wagpiir and Chanda. 



The rock becomes red near the surface. It has been largely quarried. 4 



11. Fine compact variegated lilac and grey sandstone, slightly felspathie, 



containing Glossopteris, &c., used for the floors of bungalows. ... 6 

 From this bed all the Silewada fossils have been obtained. 

 13. Compact grey and purplish sandstone used for building, base not seen. ? 



Bed 8 appears to be Mr. Hislop's bed A, and the underlying beds, 

 his division B. It is difficult to account for his considering No. 8 the 

 highest bed seen, unless he looked upon the fine-textured beds, 4 and 5, 

 as repetitions of 10 and 11. But it is clear that all form one continuous 

 series, one bed after another crops out with the greatest regularity. 

 It is true that at the base of No. 8 there is slight irregularity of 



* These are the " iron bands" of Mr. Hislop. 



t This is perhaps similar to the brown bed observed by Mr. Hislop at Bokhara.
