clay-slates and bands of limestone, which are, however, there associated 
with the trap-flows already described. 
Before leaving the Chey-air field, it may be as well to notice a few 
PU pae more particular features of some of the limestone 
beds. Among the lowest of these in the series 
there are some very peculiar breccia beds of light grey limestone, which 
are perhaps best seen a mile or so south-west of Reddypully. These 
breccias are most extraordinary in their crowded fragments of pale blue- 
grey compact limestone of every size, from small pieces to blocks of two 
or three feet in diameter. The fragments are of laminated limestone, 
and, to a certain extent, are arranged laminarly in the limestone matrix ; 
that is, in addition to any laminar arrangement which this debris may 
have assumed in deposition, they seem to have been stretched with the 
beds and so to have obtained an attenuated look. It is difficult to 
account for these breccia layers, very much in the same way as it is 
difficult to account for the evenly stratified breccias of the Jummul- 
mudgoos im the KARNULS; for, without any apparent disturbance in the 
strata of limestone subjacent to the breccias, it 1s unaccountable how 
such rough materials could have been carried along by the water unless 
they had denuded the surface of the calcareous deposit on}which they 
are resting. It is conceivable that the lower layers may have been to 
some extent solidified, and that the debris of the breccia was thrown or 
brought suddenly into deep water through which it settled down. 
quietly on the previous layer. And yet the breccia beds are thin and 
spread out over rather large areas in tolerably uniform beds; and not 
heaped as would at first sight seem to be the result of a sudden 
influx of angular debris. The beds are, however, evidently local, both 
in their extension and in their thickness. The interstices are often 
filled with fine sand. There are sandy layers among the beds, and 
towards the top shaly strata, while over these come brown sandstones 
(quartzites) in thin beds.
