precipices. At the bottom of the hollow is a copious warm spring 

 (temperature 82°). 



South of Harar the rocks are greatly crushed. The Nari beds dip 

 sharply to the eastward, and are abruptly cut off ; 

 this being repeated more than once. There has 

 evidently been a great squeeze and some faulting. The Nari beds con- 

 tinue about 2 miles south of Harar ; thence to the Gaj only patches 

 occur on the top of the Khirthar. 



The Nari outcrop is comparatively narrow on the Salari and Khurbi 

 Nari outcrop on Maki (Koorbee) streams, where the dip is nearly the 

 Nai - same as that of the overlying Gaj beds ; but to 



the south again on the Maki Nai, as further to the north, the dips in the 

 Nari beds are lower, and the outcrop much broader. It should be noted 

 that the average breadth of the Gaj outcrop on the map is much greater 

 than the thickness of the group would alone account for, partly because 

 the hard limestones near the base of the Gaj beds cover the long eastern 

 slopes of hills, the mass of which is formed of the Nari sandstones. The 

 diminution in breadth of the Nari outcrop is also in part due to the lower 

 beds being turned up sharply close to the Khirthar outcrop at the base of 

 the main range. 



The Gaj beds on the Maki Nai are composed, as usual, of limestones, 

 Gai and Manchhar w ^ n sna l es an< l sandstones near the base, and 

 beds on Maki Nai. brown and reddish sandstones, many of them 



calcareous, and clays above, the uppermost beds being variegated clays, 

 with some grey sandstones forming a passage into the Manchhar group. 

 The latter, so far as it is seen, is chiefly composed of sandstones ; the clays, 

 which elsewhere form so large a proportion of the formation, are incon- 

 spicuous, and the bands of conglomerate are few in number and of small 

 importance. At the base, there is a well-marked ridge of the character- 

 istic grey sandstone, which can be traced for many miles north of the Gaj. 

 This grey sandstone bed on the Larkanda (a tributary of the Maki 



Passage beds between Nai to the south of the main stream), and on the 

 Gaj and Manchhar. MakiNai itself, rests upon clays of various colours,-—
