Mr. Babington on the Island of Salsette. 3 
brown colour, resembling the rust of iron, and the stone to the 
depth of about three quarters of an inch has undergone partial de- 
composition, and assumes a dirty red colour. The stone is suf- 
ficiently hard to strike fire with steel, but it is easily scratched by a 
file : its fracture is irregular and its grain not 'very close. 
I am informed the rocks along the whole of the western shore of 
Salsette, particularly near a place called Versooa, have the columnar 
form. The western hills of Bombay bear traces of the same form- 
ation also, but the Bombay rock is much darker in colour, closer in 
grain, and of greater specific gravity and hardness, than that of 
which the Dharaire pillars are composed ; and the different shafts 
of which the clusters are made up, are cemented together by thin 
strata of a lighter coloured substance, instead of, as at Dharaire, 
merely fitting closely to each other.
