most rock. The sandstone exactly resembles that of the Silman Pass ; 

 in one or two places I perceived sandstone conglomerate, but in small 

 quantity. 



Cordeonah, 9th March. — About two miles South of Laindurrah 

 commences the Cootie Calee Ghaut, which is not so extensive as that 

 of Deosir. It is composed of sandstone, beneath which is clay slate, 

 although it is usually exposed in the same manner as at Deosir, be- 

 tween Genowlah and the Pass. After passing over sandstone conglome- 

 rate, I came on large bedded masses of granite, which appeared occa- 

 sionally the whole distance between its first commencement and this 

 place. Its junction could no where be observed on account of the 

 thickness of the diluvial soil. The granite contains a considerable 

 portion of felspar and white mica, the quartz is least in quantity. 



Kalapan, \0th March. — Between Ordunnah and Cheereegaon, gra- 

 nite with felspar and white mica. In one spot a trap vein of the 

 usual kind. Near Cheereegaon I observed concentric lamellar granite, 

 similar to that of Hyderabad. It generally appeared in large bedded 

 masses. The bed of the nullahs and rivers were composed of granitic 

 sand. 



I observed some masses of the laterite, very similar to those of the 

 banks of the Kanhan at Mahoda. The range of hills, which appear to the 

 Northward, are called the Baruh-puhar ; the Maha Nuddee runs on 

 the other. 



Sumbulpoor, Wth March. — On my road hither, I frequently observ- 

 ed the granite and the usual trap veins. Shortly after approaching 

 the termination of the Baruh-puhar range of hills, I observed 

 gneiss, which appeared to lie in planes of stratification parallel to the 

 range. These appearances continued as far as the bed of the river, 

 which is covered with masses of gneiss. The bed of the river con- 

 sists of sand not much comminuted. In this bed the diamonds are 

 sought for ; they are found in a black sand below the upper sand. It 

 is said that no diamonds are found in the river above the confluence of 

 the Eeb, and it is supposed that they have their origin in the rocks in 

 that river, or on its banks. The Company have the right of search, and 

 in their hands it is not at all productive. The Rajah of Sumbulpoor 

 offered a rent to the Company for right of search. 



Sumbulpoor, \6th March. — I went this day to visit the diamond
