is a variety of gray wacke or rather transition greenstone. This rock is tough, 
and difficultly frangible : it has a somewhat shining aspect, and appears to°be 
composed principally of felspar and quartz. Its color is alight, greenish gray. It 
does not exhibit a conglomerated or re-united appearance, but is occasionally 
minutely porous ; the pores being tilled with a soft earthy matter, apparently of a 
magnesian nature, and occasionally with a red ferruginous substance. When 
breathed upon, this rock exhales a strong aluminous odour. The whole of the 
eastern slope of the range is formed of this rock, which we shall distinguish by 
the letter («). l\e next come upon a bed of a soft friable slate (/>), which may 
be described as a talco-argillaceous schist. It is of a light grayish color ; is soft, 
so as, in many instances, to crumble between the lingcz’s 5 it lias a distinct greasy 
teel its texture is fine schistose, and it has a silky, somewhat shining lustre, 
the crop fracture being earthy. The breadth of the bed is about six feet ; we have 
then three feet of the rock (a), succeeded again by two feet of (6), and this 
series is carried on through several alternations, till covered by the soil at 
the base on the western side. The schist of the first bed is harder, and more gritty 
than that of the succeeding. The slopes of the hills are strewed by rolled stones, 
which must have been transported thither from some distance. These consist prin- 
cipally of conglomerates of a ferruginous nature ; and several specimens of iron 
and manganese ores, from the same situation, were shown to me by a friend, to 
whom I am much indebted for the assistance which be has given me in drawing up 
ttiis short account. Numerous quartz veins are observed to traverse the rocks of 
this range : they, generally speaking, dip to the N. E. 
To the west of this position the plains are still covered with a deep soil, through 
which, occasionally, protrude hills and hill ranges, many of which exhibit a bold and 
craggy outline. The predominating rocks are different modifications of quartz 
rock, many of which are ferruginous. 
Near the ancient city of Bidna, which lies 50 miles W. S. W. from A gra, 
there occurs a series of alternations of a ferruginous quartz rock, with a peculiar 
conglomerate, containing imbedded agates, agate jaspers, &c. & c. : these occupy 
the rugged termination of a hill range, which stretches from this point in the 
direction of Ajmer. Into a description of the Biaua rocks I shall not enter at 
this time : they form in themselves so interesting a subject, that they are well 
deserving of a separate consideration ; — as surface rocks, at least, they occupy but 
u small space in the Bhartpur district ; but they may, perhaps, be continued on 
into the Gvvaliar country : — at least agates, agate jaspers, and conglomei'ates of 
different kinds would appear to be of common occui’rence in that district. 1 have 
been told that copper mines were at one time worked somewhere in the left of 
the subme/Mal rocks, described as flanking the Bhartpur district. The exact locality 
of these I am not acquainted with. Iron, too, is of abundant occurrence in the 
same belt, and might, perhaps, be manufactured with advantage. 
From the above description it would appear that the Bhartpvir district is situated, 
geologically speaking, to the east of the Jezpur branch of the great primitive 
formation of Central India, and that it is separated from this branch by a belt of 
transition i*ocks- The newer sandstones of this district would also appear to 
belong to a great series of rock formation, which lias been traced through a large 
portion of Hindustan, and which forms, with but little interruption, the north- 
eastern and southern barriers of the valley of the Ganges and Jumna. 
This series is probably continued on, both to the north azzd sozzth of the primi- 
tive branch just alluded to, making a sweep on one side into the Penjdb, azid on the 
other into Uarauti, Malwa, and M<*war, where it takes a turn to the south, and 
is still seen skirting the primitive strata of the last district : — the older sandstones 
which have been described as occurring in the Bhartpur district, have, in other 
situations, been observed to basset out through the newer sandstones ; and future 
observation may, very probably, discover, in this portion of the country, the out- 
croppings of other sti*ata, zvliich may coznplete the series between the old and new 
red sandstones of the English geologists. Rocks of the submedial order would 
also appear to be very generally interspersed between the newer strata and the pri- 
mitive formations of Central India, both on the north and south of the Jeypur 
basin. This is a very vague and genez*al descz’iption,butIhave alz*eady tz'espassed 
too much on your space and on the time of your readers, and I shall, therefore, 
conclude for the present. I*
