ceous black shaly layers, and near the top a purple clay band. In the 

 sandy limestone-layers crinoid fragments and numbers of small Fusidince 

 occur, while in the river bed are fallen masses of greenish weathered, cal- 

 careous -S^Mv^er-sandstones, and sandy beds with large annelid tracks. 

 Still further up the stream the fault crosses it, cutting out the carboni- 

 ferous beds obliquely in the hill side to the south, and the river runs 

 between steep' nummulitic limestone cliffs, exhibiting much crushing and 

 disturbance, the beds being turned upwards towards the fault and dipping 

 at angles as high as 50° from the northern flanks of the hills. The same 

 limestone forms the country as far as Sodhi,* and it extends much 

 beyond this place. Quantities of calcareous tufa

At about a mile to the westward of the Upper Katta village^ which is 

 situated opposite to the mouth of the Nursinsr-

phoar gorge, there is a considerable salt-spring, 

 conspicuous from a distance, on account of the quantity of calcareous 

 tufa which it has deposited. It issues from the " purple sandstone, " of 

 which there is rather less than usual here, and the spring seems to 

 come from the lower part of this formation, purple marly and shaly layers 

 being seen in the vicinity. 



On the hill above this spring the following section is seen (taken 

 from Dr. Waagen^s notes), the "olive group ^' or cretaceous beds bein^ 

 no longer present : —

* There are two places of so nearly the same name, or one which sounds so exactly 

 similar, that it is difficult to distinguish them. The other one lies a mile and a half west- 

 ward of Katwahi, and is spelled on the map Sothe.
