Boghelcund, and the Districts of Saugor and Jubulpore. 197 



incumbent associate is massive schist. The slate might be used for archi- 

 tectural purposes, though not particularly fine. Its colour is dark lead, ap- 

 proaching to black. After the slates follow the schistose limestone, quartz rock, 

 and dolomite. The former limestone, as well as the latter, contains mao-nesia' 



From Jubulpore I returned to Tendukaira by another route, alon"- the 

 metalliferous range which it was my business to examine : but I shall refrain 

 from giving- any account of its mines, for the same reason which I have 

 alleged in my description of Tendukaira. I must also defer sendin"- a map 

 of this portion^ which 1 have constructed on a large scale, in order to show the 

 position of the mines, until a future opportunity. In the mean time I may 

 observe, that a part of the southern barrier of the valley of the Nermada river 

 is composed like its northern opposite Tendukaira, Sermon, &c. of trap 

 rocks, the contour of which I have laid down to the extent of eighty miles • 

 and I trust that a future opportunity will enable me to complete the whole. 



The result of my inquiries respecting- this eastern deposit of overlying- rocks 

 is, that it extends southward as far as Chuparah, and thence eastward towards 

 Mandela, Omercuntuc, and Sohagpore ; but whether it unites with the great 

 central mass, I could not learn. It is somewhat harder than the trap of Saugor^ 

 but does not essentially differ from it in character, though it differs g-reatly in 

 its substratum, which is here granite or gneiss. 



In the re-entering angles of the trap-hills, the occasional appearance of the 

 primitive formations may be traced ; and, in a cluster of such hills, about one 

 mile south of Bograi, the rock is composed of mica, quartz, compact felspar, 

 and chlorite, intimately intermixed in fine grains, and is somewhat friable. 

 In the same hills also occurs a conglomerate composed of rounded pebbles of 

 primary rocks ; but it contains no fragments of greenstone or basalt^ although 

 the hills in question are nearly surrounded by trap. 



After passing- Bograi the valley expanded, and was covered by a thick 

 deposit of alluvium, through which the dolomite occasionally cropped-out for 

 a short distance ; but, with these exceptions, no rocks appeared above the sur- 

 face until I arrived at Keerpani, where the hills were composed of stratified 

 quartz rock, sometimes granular, but more frequently compact, and contain- 

 ing felspar. The strata were highly inclined, and sometimes perpendicular; 

 and there was no rock, except quartz, between Keerpani and the sandstone hills 

 of Arrijerro, which are on the boundary of the sandstone and trap formations 

 of the Saugor district. 



To this enumeration of rocks may be added a very curious calcareous con- 

 glomerate, which is found in the bed of rivers whose source or whose channel 

 is in trap districts. I have observed it in the bed of the Sonar river, north of
