106 Memorandum on the Geological structure [No. 2. 



The latter attains considerable height, and divides the estate of 

 Dhulbhoom in half, joining the high hills of Mohrbunj to the South. 



In the South of the Colehan, a table-land rises rather abruptly to 

 the height of about 1000 feet above the level of the sea. This 

 table declines gradually to the West, South and South East. In 

 the latter quarter it joins the base of the high mountain Badani in 

 Mohrbunj. This table is composed of gneiss, greenstone and meta- 

 morphic rocks. It is for the greater part cultivated, and was 

 formerly the site of many populous Hindu villages, from which the 

 inhabitants were expelled by the Coles. 



The river Byturnee collects the drainage of this table to the South 

 "West and the Khurkhy to the East and South East ; the former 

 flowing South East into the Bay of Bengal and the latter North 

 Easterly into the Soburno Rekha. The Baminee (not the Byturnee, 

 as shown in most maps) receives the waters of the Western portion 

 of the district as the Suburno Rekha does, the whole of those of the 

 Eastern portion. 



Eastward, in Dholbhoom beyond the Sooburno Eekha, hills gradu- 

 ally disappear; the surface of the country exhibiting undulations 

 which imperceptably merge into the plains of Midnapore. The 

 soil in the more elevated portions of these undulations, consists of 

 Laterite abounding in iron. A variety is extensively smelted for 

 that metal. 



To the north-east the hills cease more gradually and extend 

 further to the eastward, but they appear to be succeeded by the 

 same laterite soil as to the south. 



It will be seen from what has been said, that the Singhbhoom 

 division is a very hilly country consisting geologically of rocks 

 either of igneous origin or of slates, schists and old sand stones 

 more or less altered by the action of heat. 



In such formations minerals are commonly found, and this district 

 forms no exception to the general rule. The metals known to exist 

 are gold, copper, bismuth, and iron ; the existence of tin is believed, 

 but the ores require further examination. 



To the above list may be added the other mineral products useful 

 to man. These are, as far as yet known, potstones, ochreous earths, 

 and corundum s. I propose to detail the localities in which each
