COAL OF THE TOWA.

ed calcareous concretions, which are varieties of the kunkur 
formerly alluded to. On breaking these, we find them hol- 
low, and the internal surface studded over with crystallisa- 
tions of calcareous spar. 
Coal occurs in the bed of the Towa, about eight miles 
east from Hussingabad. I found many pieces of the 
same coal near the junction of the river with the Ner- 
buddah, but they had all been brought down by the stream 
from the hills, where it is probable extensive beds of this 
combustible exist: and from the fact of ironstone also 
abounding there, and the extreme dearness of the metal, it 
becomes an object to explore the whole surrounding hilly 
country, and to trace the course of the river, in order to 
discover the situation of the mineral.

MemarJvs made on a Ma7xh from Hussingabad to Sanger^ 
and from thence to the Ganges. 
The specimens labelled " From Alulwah^''^ were picked 
up by me on a hasty march which I made from Hussinga- 
bad to Sangor, and thence to the Ganges, in my way to 
this place. I had no leisure to examine the geological fea- 
tures of the country minutely; but the few memoranda 
which I noted down at the time, defective as they are, may 
still give some general idea of the nature of the rocks. I 
shall therefore transcribe them without alteration.
