be used except as rougli builcliug stones; and the sandstones of the Kajinahal beds 
ai’e not hard enough, except in a very few cases, to be of much value. Neither Mr. 
Oldham, Mr. King, nor myself came acros.s any that were fit for first class pur¬ 
poses, such as millstones or grindstones. Nor were any of the clay beds noted 
in the Alikur and Pyanur areas of sufficiently good color to be of much value. 
The pottery clays used by the people are taken from the younger lateritic or 
alluvial deposits, and are, as a rule, of very inferior quality. 
On the continuation of the road section from Mureee to Abrottabad, 
hxj A. B. Wynne, F.G.S., Geological Survey of India. 
In a former paper (Vol. VII, p. 64), I described the section from Murree 
to Kalabagh Post, along the upper or military road through the galis (“gullies”), 
as it is usually called. 
At Kalabagh, the summit level of this road (about 8,000 feet by aneroid), 
the nummulitic limestone and shales of the hills are in junction with the azoic 
Attock slates of the Mian-jani-ka Chowki range, this junction being ajiparently 
effected by means of a fault concealing all of the intervening rocks that may be 
present. The slates are much folded and, about half way between Kalabagh and 
Baragali, include a band of the usual frilled, dolomitized, seemingly slightly 
altered and entirely unfossiliferous limestone found elsewhere in these slates. 
It extends in the strike across the ridge supporting the road, and similar bands 
may be seen projecting at the surface of a sj)ur from Mianjani mountain, and 
forming the crest of another ridge running out westward from Baragali, in both 
cases with a northerly dip. Near the last-named place the slates contain bands 
of hard dark grey or bluish silicious sandstones, and further on down the steep 
incline to the northwards at Bantangi purplish-red slab-slates occur near the 
junction with the limestones of the northern side of the great Mianjani slate tract. 
The, junction here differs fi’om that at Kalabagh, but has scarcely less the 
appearance of a faulted or dislocated contact, the plane of which is partly verti¬ 
cal and partly sloping to the north, for on the western side of the Batungi Kad, 
the limestone, almost entirely concealed by dense forest, slopes upward and 
backward to the south, while the whole hill face on the opposite side of the 
Kad is of slate, as usual crushed, contorted, and folded. 
Just at the contact, whoi’e a pui'plish color pervades the slates in some 
places, the next adjacent rocks are vortical light-colored quartzites, of small 
thickness, succeeded by compact and sandy limestones containing many impres¬ 
sions and sections of brachiopods, mostly of small size, many of them resembling 
casts of Terebratula; some obscure spiral gastropods, and some layers crowded 
with the curved fragments of small bivalves also occur. These hard limestones 
have nothing beyond the most general similarity to the hill nummulitic lime¬ 
stone beds; they are often dark or nearly black, and some of the bluer layei’s 
present a curious but characteristic yellow-mottled appearance frequently ob¬ 
served in the limestones of the Dungagali and Changlagali road, where these
