I.— INTRODUCTION. 



The observations recorded in this paper were made during the 

 first four months of the new century. The first part of the field season 

 1900-1901 was spent in the adjoining part of Jeypore zemindari, the 

 geology of which is in many respects similar to that of the Kala- 

 hand state. About twenty years ago the north-western part of the 

 state was traversed by the late Mr. Ball of this department, who pub- 

 lished some notes l on the geology of the country explored. 



The Kalahandi state is not easily reached, being nearly two hundred 

 miles from Raipur, the only large centre connected with it by a good 

 road. Comparatively bad roads lead to Sambalpur and to Viziana- 

 gram, but even then the distance is over a hundred and thirty miles. 

 The state is not so backward as might be supposed from its isolated 

 position,
