the Damudas were either only deposited in small detached areas, or were largely denuded 
prior to the deposition of the Kamthis. 
In the present case the beds of the hill station do not seem to be underlaid for the whole 
of this floor, hut to have overlapped the Damijdas to the eastward; and on this account 
it is to be feared that the coal measures will not he found constant throughout the field. 
There are two other small outlying hill masses of Kamthis, a few miles to the north-east 
of the Singareny field, which are in general character exactly like the hill station, or of a 
steep-sided plateau form, and made up of nearly horizontal beds. One of these is above 
or immediately north of Dharmapooram; and the second further north-east between 
Kamaram and Anantarum. A couple of miles further east, is the south-western edge of 
the main area of Kamthis. Now, there are no signs of Damudas under this south-west 
edge; nor are there any under the second of the two outliers mentioned. There are, however, 
grey and pale huff sandstones at Dharmapooram underlying the hill of Kamthis, possibly 
Damudas, though I saw no trace of coal; and it might he as well to examine these rocks 
by boring* 
In the southern part of the field, the Kamthis are very strong, particularly on the 
eastern edge after the stream from the Kollapoor tank is crossed. Here they form some low 
ridges, and have a dip of 20° or 30° westward. The country is, however, so covered up by 
clay and sandy deposits and jungle that it is difficult to make out the lie from these ridges to 
the western edges of the field opposite Singareny; or to tell if any undulation brings 
Damuda beds up to within easy reach of the surface. Some of the beds on the western edge 
opposite Singareny in the valley of the stream from Kollapoor, &o., seemed to be Damuda 
sandstones. Borings should he put down right across this part of the field, and certainly ; 
below the eastern slopes of the ridges on the eastern edge. 
I have indicated in the map where it would be advisable to put down bore holes. In no 
case does it appear as if these would ever need to he sunk more than 200 feet at the utmost, 
and most of them, particularly in the middle of the field, would seldom exceed 50 feet. In 
all cases the borings ought to he sent down to the gneiss (the greater part of the floor of the 
field is possibly of crystalline rocks), except in the neighbourhood of Kumpaid, where Talchirs 
will be met with; or to the Yindhyans (hard quartzite, slates, and siliceous limestones) 
northwards from the Yellindallapad stream, or in the southern end of the field.
