58 BOKARO COAL-FIELD. 



judged it would be almost a waste of time to run sections in botli. 

 Scarcely any of the smaller streams which I have mentioned were 

 marked on the map furnished to me. I had therefore the task of plot- 

 ting them forced upon me in addition to my own work. The length 



of time thus involved in making as approxi- 

 Maps. 



mately an accurate map as I could, rendered it 



imperative that I should employ my judgment upon certain occasions, 



so as to distribute my time to the best advantage. Thus the outcrops 



of some few seams in this district may not have heen traced with the 



same care as those in the more important fields to the east. From the 



number of seams that have been described in the report and marked 



upon the map it may, however, be conjectured that very few could have 



escaped detection. 



I may here remark that every stream west of Layeo has been 

 altered, or mapped for the first time by myself. From the junction 

 of the Bokaro and Chootooa to that of the former river and the 

 Hoharoo, every nuddee has been put in by me. The Bugjobra was 

 measured carefully throughout, from the boundary to its outfall into 

 the Bokaro. The Chootooa has been entirely altered. And the 

 Bhagalatta, Sut Nuddee, and others of its tributaries which had all 

 been omitted, have now for the first time been laid down. The 

 Chumargurha, the Foosro nuddee, the Mungurdooha nuddee, the Moorpa 

 nullah, the Kubode nullah, the Gobiupoor, and the Mando nidlahs 

 are all new. The Hoharoo has been entirely newly plotted. The Bokaro 

 itself I found necessary to replot, otherwise I could never have mapped 

 its seams correctly. 



East of Loogoo hill ; the labour has been almost the same. 



The coal in the Barakars is much the best in the field ; but it is 



not to be compared in its general quality with 



that obtained from the same group in the Jherria 



!Field. Individual seams are good, especially one referred to occurring
