cliff 85 feet high. The beds soon begin to undulate^ and some of the 

 underlying speckled and red sandstones are placed by slips or faulting 

 amoug the limestones. Further on along the north side of the -Wan 

 or glen^ the lavender clay beds o£ the speckled sandstone group 

 predominate, grey clays and ferruginous bands with white efflor- 

 escences appearing among them. At one spot the dark greenish shaly 

 Silurian zone is only 30 feet thick, the overlying " speckled 

 sandstones^' having an apparent thickness of only 40 or 50 feet. The 

 hard sandy beds of the carboniferous group are seen in the little 

 amphitheatre at the head of the glen, beneath lofty nummulitic lime- 

 stone cliffs, the bedding of which rises rapidly towards the Kanda- 

 wala peak, and the carboniferous rocks also cover the high ground 

 between this and Nali. They are white, grey, thin and thick bedded 

 limestone, with many strong beds of fossiliferous, drab, earthy and sandy 

 calcareous rocks, separated by shale partings. The Fusulina here occur 

 in grey compact limestone far down in the group, and also in more 

 sandy beds at a still lower horizon. The " speckled sandstone ■'' group 

 below these limestones is more shaly than usual, earthy bands predomi- 

 nating in its upper part, and occurring again within 30 feet of its base. 

 On the side of the hill over Nali this group (No. 5) has a thickness of 

 150 to 200 feet, and is surmounted by an escarpment-cliff of carboni- 

 ferous limestone, much acted upon by the weather, as is shown by a 

 poised fragment 15 feet in height, which has been gradually separ- 

 ated from the cliff by atmospheric waste.
