road near Kyari Gliat (13| miles from Simla). About 100 feet in vertical height, below 
the cart road, the limestone crops out and is exposed for some little distance, and is 
then lost owing either to a sudden twist in the line of strike or a small fault. At no 
great distance, however, to the south-west of this point, it crops out again in great 
force in front of Wakna and shows along the path leading to Mamleg* for about half a 
mile, and is seen resting directly on the conglomerate. It then crosses from the south to 
the north side of tlio spur, and shows almost continuously down to the Chiama hamlets, where 
conglomerate of the Ussan type is abundant. The strike now becomes north-westerly, and 
the limestone shows abundantly through the several Chiama hamlets until it is lost in the 
cultivated fields overhanging one of the tributaries of the Camber. Prom this point the 
Blaini rocks strike directly for the south end of the Syri hills, and though the limestone 
does not again crop up until the G amber is reached, the conglomerate can be easily traced 
under and in immediate contact with the Infra-Ivrol slates. On the right bank of the 
Gamber the limestone re-appears, and beds of from 10 to 15 feet in thickness are repeated 
several times by crushing, the Iufra-Krol slates being caught up in the folds. Above the 
limestone are tire black slates of the Iufra-Krol series, and below it the conglomerate in all 
its varieties in great abundance. 
Prom the Gamber there is an almost unbroken outcrop of the limestone through Jabal- 
Bakesu and Khairi-Bakesu on to Mamleg. On the ascent up to Mamleg, the limestone gets 
astride on the back of an anticlinal that extends up to the Syri road, and consequently 
spreads out to a great width. At Mamleg and below it the limestone is seen in great pro¬ 
fusion. The extension of this bed in a south-westerly direction would take it to the Syri 
road above Haripur. On the edge of the Mamleg plateau it is seen overhanging the inter¬ 
vening valley, and a limestone re-appears on the other side. It crops out near Dochi on the 
Syri road and along the crest of the ridge, and then dips under the nummulitic rocks, as 
represented by the pisolitic bottom-rock of the Sabathu group. I cannot be certain that this 
last described limestone (the Dochi bed) is the Blaini rock, but I think it is. 
Tiie north-westerly outcrop of the Blaini limestone may be followed from Mamleg until 
it nearly reaches the Haripur and Syri road. On the road side the conglomerate (the 
Ussan variety) is seen dipping south-west and north-east. The limestone continues under 
the road for some distance, until at last it cuts across it close to where a turn in the road 
brings the Syri Bungalow into sight for the first time. Prom this point (proceeding towards 
Syri) the outcrops on the road side are numerous. The limestone is also seen in cliffs below 
the road, being outcrops along its north-easterly line of dip. The conglomerate of the 
Ussan variety is here very abundant. The limestone forms the crest of the ridge where 
the road shifts for a short distance from the east to the west side of the ridge. It finally 
leaves the road about one mile from the Syri Bungalow, and strikes in a north-westerly 
direction. There is a constant outcrop through Bama and Barog to Chauog, and thence on 
to Sharar (Surair of the map), where I shall for the present leave it and return to Simla. 
Following the line of strike to the westward from the Lakri Bazaar, the Blaini lime¬ 
stone is well exposed on the lower roads below the bazaar leading from Waverly to the 
Willows. It there strikes down the hill side and has frequent outcrops until hidden by the 
wood under the Union Church. It re-appears on the spur about 200 feet below Wheat- 
field, and from thence the outcrop is pretty continuous to the Simla and Bajji road, which 
it crosses at an elevation of about 6,500 feet. From this point its course is just under 
Annandale to the east side of the Yarrows spur, which it crosses at about 600 feet in vertical 
height below that house. It is well exposed again on the west side of this spur, and it 
* Mamleg is a village on the western side of the little transverse ridge to the south-west of Hamahi of the map. 
A line drawn from Sairi through Hamahi would strike it.
