and in most other places, no appearance of stratification can be observed. Its 
horizontal disposition 2 may, however, be very clearly discerned at the iron mine, 
near Partapin, in the division of Fayezullahgunj, where it forms the horizontal 
floor and roof between which the ore is contained. 
Very nearly allied to the above, is what is called hornblende in mass, which 
differs chiefly in being much softer, although it still retains a great degree of 
toughness, and resists the action of the air much longer. It takes a tolera- 
ble polish, although inferior to that of marble, with which, however, it is often 
confounded. On account of the ease with which it is wrought, and of its durability, 
this stone is in great request among the natives. At Paingti it is found in rounded 
masses, immersed in a soft substance, evidently consisting of the less durable parts 
of a rock of the same nature now gone to decay. In 5 „ Ine places this rotten mass 
has lost all traces of its origin, and has become a deep red soil, in which masses of 
the hornblende are found imbedded. Masses of several feet in diameter, and quite 
sound, might be procured ; but the natives content themselves with smaller ones, 
which they cut into the stones on which they grind the materials for making curry and 
many other substances. This stone, some say, should be called Tiliya ; but others 
allege, that its proper name is Sangkhara. On the hill named Taruya, near Paingti, 
has been a quarry of this stone, from which great quantities have been taken it is 
said, during the Mogul government. The place is conveniently situated, and very fine 
masses nnght be produced for building, no part of the rock having as vet decayed 
The two stones hitherto described, whin and hornblende, were' by VVallerius 
classed together, and called hornstone, (Lapis comeus) and both the arrangement 
and nomenclature seem excellent, as both stones possess great toughness without be- 
ing very hard, and as their colour resembles that of a black horn. Modern mineralo 
gists, however, in the progress of their science, which seems, both in arrangement 
and description, to be retrograde 3 , have applied the name hornstone to other” mine- 
rals which have little or no resemblance to horn, and which are flint in the mass or 
rock. At Sakarigali, close by the edge of the water, in winter, is a curious horizon- 
tal layer of this stone, not above a foot wide, but exceedingly difficult to break. It

A substance, which naturalists include among the clays, but called kkari by the 
natives, ,s very generally diffused through these hills, and several quarries of it have 
been and still are wrought. When perfect it is a substance somewhat like chalk but 
is not calcareous. Women m many parts eat it, when breeding, as in Bengal they eat 
baked clay ; and some of it for this purpose is exported to MurshidaMd Bovs « l ...,
