250 NEEBUDDA DISTRICT. 



But there is still another fact to be noticed which bears on the 



Farther considerations question of the disturbances of which our district 

 connected with disturb- 

 ance, has been the theatre. 



It has been stated that the general direction of the southern boundary 

 of the lower Damuda and Talcheer rocks is parallel to that of the north- 

 ern boundary of the same rocks, and of the Mahadevas, but it may further 

 be seen from the map, and is very strikingly apparent on the ground, that 

 all the valleys of the area inclosed between these limits, are also parallel 

 to these boundary lines. Ranges of hills run east and west whose steeper 



face is generally towards the south, and the more 

 Parallel valleys. 



gentle slope northwards. Chatur Doria, and the 



outer range thence to Bogra and the Tawa, is succeeded on the south by 



the great physical feature of the district, that range of which the lofty mass 



of the Puchmurri is the culminating point. This ridge presents a nearly 



continuous vertical cliff facing south, {Fig, 22, p. 249,) throughout the 



whole of its length, which stretches many miles to the west from Puchmurri. 



Parallel to and south of this again, and imitating on a smaller scale all its 



principal features, we find another east and west ridge, with a precipitous 



face towards the south, in which Gidundeo and Mandeo Peaks rise to a 



considerable height. Asseerghur fort stands on a ridge still further 



to the south, which keeps a similarly parallel direction ; and finally, 



between this range and the southern boundary of the Talcheer beds, 



(itself marked by the lofty east and west range of Persakote and 



Muttardeo) we find another great ridge, both the north and south face 



of which present sheer escarpments and steep slopes. All these are, as 



has been stated, indicated on our map, but they form on the ground 



very remarkable and striking features in the physical aspect of the district, 



and impress the observer strongly with the conviction that the parallelism 



which has been stamped in such characters on the structure of the whole 



country, must be due to some uniform and widely acting causes. 



It may be well to remark here, that the great majority of the trap
