Owing to the water and rushes the section is no longer clear, and no 

 coal is exposed at the surface^ until the junction of this stream with the 

 Damoodah. 



West of Dhooree (that is the portion of the village or toleJi in 

 which the Teekadar resides) is the Chutkurree nullah. Some seams 

 crop out in it, but they are inclined at high angles, and of very bad 

 quality. Nevertheless I have mapped them for purposes of reference. 



The dips in this locality are very various, twisting remarkably sharply 

 in some places. Many of the beds approach in character the Eaniganjs. 

 This resemblance is oftentimes so strong as to mislead, especially when 

 we recollect that lithological identity of character is almost the only 

 ground which Indian geologists have to go upon in recognising rocks for 

 the first time. Organic remains are so rare in the Damuda series that if we 

 depended upon palseontological evidence in order to define the boundaries 

 of its difierent groups, an extravagant expenditure of time would probably 

 take place before the typical specimen required could be found — an 

 expenditure which the present requirements of India do not call for. 

 So that, as a rule, the test of superposition, and when that is wanting 

 similarity in mineralogical character, are the only two bases for classifica- 

 tion which we can go upon. Still even in this area there are instances 

 in which it would have been most rash to assume that a, lithological 

 resemblance justified us in correlating certain beds.
