with, but to the west it is not seen in situ. This peculiar bed is very irregularly denuded. 
Just south of Bara Castle channels are cut through it to the depth of the bed, leaving the 
rock standing in columns some feet square, and large and irregular patches of it extend for 
nearly a mile towards the south. 
The following is a sketch section of this peculiar bed :— 
a—Par quartzite ; bb x —Peculiar bed; c—Shales, &c., of Morar group. 
The bed presents some variety. At the point b, x it is composed of alternations of 
limestone and silicious bands; the former being softer are more worn, leaving the latter 
in projecting bands round the columns. The silicious bands weather into a very uneven 
honeycombed surface. Dr. Stoliczka informs me that they are formed of corals. In the 
outlying patches south of Bara hi, the limestone is entirely absent, and the bed is com¬ 
posed of a. compact quartzite, often of a peculiar oolitic structure. 
Small patches of this bed are seen resting on the Par quartzite eastwards almost as 
far as the Sindh river, hut the bed is thin, and the limestone, absent. 
Mon a 11 Group. 
The rocks of this group consist of argillaceous shales, finely laminated ribboned jasper 
and hornsttmc beds, frequently exceedingly ferruginous, but in places the iron is entirely 
absent. There is also some thickness of limestone having; the same ribboned structure, the 
bands of limestone from b to 2 and 3 inches thick alternating with silicious hands varying 
from a line to an inch in thickness. The silicious hands are often of red jasper. 
Trap .—The group includes several spreads of contemporaneous trap, one of them 
of great thickness and extent. 
Thickness .—It is difficult to estimate accurately the thickness of this group, as in 
parts of the .section the beds have a slight roll, but I should say that it must be at least 
2,000 feet thick. 
The line of junction between the rocks of this anil the Par group is marked by a slight 
rise in the ground, seldom more, than 30 feet above the top of the Par quartzite. 
It is an irregular line, roughly parallel to the Par scarp. At the west end it is only 
a few yards north of the scarp ; but eastwards the distance gradually increases, until oppo¬ 
site Deogurli, there is a. distance of nearly five miles between the two. 
Badhano .—The only actual junction between the two groups s n along .the line is 
at Badhano. Here resting immediately on tlie Par quartzite are about 30 feet of white, 
reddish, and light green micaceous shales. 
It is doubtful if these shales exist along the whole line ; at all events, there can be only 
a few feet of them in places; they appear to be overlapped to the south, as the further north 
the section is situated, the greater the thickness of the shales exposed. Thus, a well situate 
by the side of the Bombay road, just on the top of the Ghat and about two miles north of 
the Par scarp, is sunk through the jasper beds nearly on to the top of the Par quartzite. 
In the bottom of the well, several feet of black carbonaceous shales are exposed, but in a 
gorge extending north from Simiria into the Par scarp lo within a mile of the well, 
although no actual junction sections are exposed, still there is only a foot or two of the section 
just above the quartzite covered. No black shales are seen in this section, they may occupy 
the foot or two covered, but, even then, there must be a great reduction iu the thickness ol
