Remainder of section obscur£. 

 In order to show that the characters of these rocks vary wdthiu 

 short distances^ I shall quote one other section taken in the neig-hbouring- 

 Paloogudha river : 



Gneiss. Ft. In. 



1. Boulder conglomerate, a portion only seen 



2. Bluish argillaceous flags, dip 10" E, covered up 



3. Greenish thin bedded sandstones ... .., 



4. Thick silty beds containing a few boulders of gneiss . . . 



5. Fine grained greenish and yellow sandstones 



6. Thicker beds ditto 



7. Conglomerate, a purple silt matrix with small frag- 



ments of gneiss 



8. Bluish-grey shales ... 



9. Grey shales ,., 



In some of the other sections met with in this neighbourhood, 



„ ,, 1 , the boulder cono^lomerate did not occur at the 



Boulder-conglomerate '^ 



not always at base. base^ silt-sliales having been found resting on the 



uneven surface of the gneiss. 



At various points along the northern boundary of the fields small 



' , „ outcrops of Tulchir rocks occur : the details respect- 



Other exposures ot ^ 



Takhirs. j^g them are not of sufficient interest for further 



notice here ; their position and relative importance will be best a2">pre- 

 ciatcd by a reference to the map.
