in the strata to a much greater extent than anywhere else; there 
appears to have been some dislocation; and the traps are both intrusive* 
and contemporaneous. 
The traps of Beddadoor Hill on the Chittravutty occur in the same 
i nop opi RAYS only to much smaller extent. This hill 
mostly UN, is made up of a splendid series of grey and purple 
ash beds (spotted shales), shales, sandy shaly flags, and a few bands of 
felstone with either one or two great flows of trap. The long eastern 
back of the hill shows a basement of trap overlaid by shales and ash 
beds up to the summit, But in descending by the path towards the 
vilage on the western side, greenstone is found cropping up rather 
quickly and suddenly from under the shales of the summit; in fact, 
appearing to cut up through them at rather a sharp angle, thus :—

To a certain extent, the shaly beds appear to merge down into 
this trap by sandy felspathic beds: elsewhere the shales are laminated 
close down to the massive greenstone, as though they had been deposited 
on an uneven surface of trap; while, again, in another locality, the trap 
seems to have cut right up against the beds, for the shales are contorted 
in their lamination close to the igneous rock. At any rate, the trap 
certainly overlies a great set of grey and purple shales with, near their 
* I tried, by again and again looking over these outcrops, to account for the abrupt 
position of the trap, particularly up the ravine part of the stream, by faulting or by sharp 
folding, looking at the intrusions from all sides; but it was impossible to come to any other 
conclusion than that they were intrusions.
