at rather low angles of 30° to 40°, thus agreeing with that at Man 

 itself where the edge of the hills is a dip-plane (see PI. 1, fig. 1). The 

 hills are jungle-covered, with no villages, except in the narrow 

 intermediate valleys where alluvium has accumulated, and they 

 are very rough going for the pedestrian. The quartzite is frequently 

 sheared, with production of platy structure and of quartz-schist, 

 and there is much vein quartz. As was remarked towards the north, so 

 here, there is no trace along with them of any limestones or slates of 

 the Mundeti series the beds of which however, have an identical strike. 

 The intrusive rocks of quartz-porphyry and Idar granite of the 

 neighbourhood will be described below (p. 126). It is not certain 

 whether the three bosses near Vagesari and the one at Lilchha, 

 Possible intrusion. to S e ^er with the string of little bosses S.S.W. 

 of Mundeti and reaching to Posina and Chhapra 

 are actually intrusive in the Delhi Quartzite or whether they indi- 

 cate the presence of Aravalli rocks in the vicinity. That at Posina 

 is certainly in contact with Delhi Quartzite and the same is certainly 

 true of the quartz-porphyry of Malasa. But the Vagdi and other 

 sections must be considered in relation to this question. 



The E.S.E. dip seen at Man is also noticeable along the south- 



Chh ril and eastern edge of the hills stretching to the south- 



Kaprc'tta.' west > whilst the cross-valley from Chhapra 



to Kapreta, in the vicinity of Nankhi, has laid 

 bare in the hills to the south-west an apparentlv continuous section 

 of fairly steeply-dipping Delhi Quartzite inclined in the same direc- 

 tion. At least this was the impression received from a view of the 

 truncated edges of the strata as seen from the opposite side of the 

 valley m the distance ; but the remaining hilly mass to the south- 

 west has not been searched in detail.

 Khed. P lat y layers, which are obviously not original 



bedding-planes, as is shown by a rough slab 

 taken at the surface near Khed. This is a good example of the very 

 complete way in which all original trace of bedding may become 

 obliterated in the Delhi Quartzite by superinduced coarse platy 

 cleavage or shear planes.
