plateau. One approaches the village from the east, over flatly bedded 
blue limestones; compact, semi-crystalline, black and bluish-grey Nerjee 
stone. Then as the stream is followed to the village, this fine rock is 
gradually lost in a thin-bedded, grey, earthy limestone, below which are 
purple cherty beds. Immediately at the north-east corner of the village, 
there are two or three thin beds of compact fine-grained, dark-green and 
grey quartzites, under which comes a bed of chert-breccia, 6 or 8 inches 
thick. -Below this, again, is a series of compact semi-silieious limestone 
on which the village is built; under these come about 20 feet of purple 
sandy and clayey shales, at the bottom of which are a bed or two of 
purple jaspery segregated limestones with sandy shaley partings. These 
rest on sandstone- and grit-quartzite of the Banaganpilly group :—

So far then as the Jummutmudgoos have been examined, it is found 
that they lie consecutively on a group of quart-

mulmudgoos on strata of  zites, though some period of greater or lesser 
eae duration must have elapsed before the limestone 
group began to be deposited ; for there are every now and then evidences - 
of the upper surface of the quartzites having been denuded to some slight 
extent, before the sandy and calcareous shales and flags or limestones 
were formed over them. 
There are, however, a couple of examples in which the limestones 
rested unconformably on a series of quartzites, which are not at first to 
be distinguished from those of the lower group. These are in the
