This description, which is the fullest in the memoir, does not in any way 

 indicate the author's view of their origin. Indeed he elsewhere says, " The 

 subrecent deposits, except in their most superficial portions, contain no 

 evidence as to the conditions under which they were accumulated,"* 



Although in one sense it is true that they are very generally distributed, 

 there are only ten definite localities where these deposits are sufficiently 

 important to be noticed. Of these one is said to be of " quartz-gravel," and 

 is thus, as will be seen, of a character different from the rest. There are 

 also six other localities where I have noticed them, making in all fifteen to be 

 considered, situated as follows : — 1. The northern slopes of the Kala 

 Dongar in Patcham.' 2. The summit of the Gora Dongar, north of 

 Andhou. 3. In the glens at a considerable elevation in Bela. 4, On the 

 northern flanks of the Habo Hills, near Kotae. 5. Below Roha Hill. 

 6. High up on the Kas scarp. 7. On the south side of the Jhurio Hills. 

 8. In the valleys of Varar Hill. 9. At Baukha, where it is quarried. 

 10. On Bhujia Uill. 11. At the base of Katrod Hill. 12. In the Katrod Hills 

 between Ler and Jadura. 13. In a valley north-west of Godpur. 14, On 

 the Mandvi road, where it is quarried. 15. At the base of the trap escarp- 

 ment at Khedoi. It will be observed that the deposits are all very local, 

 and usually associated with some hill. They appear also to be absent or 

 inconspicuous on the western side of Cutch. 



If we examine now more closely their mode of occurrence, some remark- 

 able peculiarities become obvious, which should be some guide as to their 

 origin. Thus the Kala Dongar Bills'* have a steep escarpment on their 

 northern side, and the slopes below have usually a direction parallel to it ; 

 but near the western end there is a projection of high ground forming a kind 

 of bay which opens on the west, and it is in the angle of this bay that the 

 subrecent concrete is found. In the Gora Dongar north of Andhou a broad 

 open valley is formed by a dome of Jurassic rocks, the eastern side of which 

 is bounded by an escarpment of limestone rising towards the north. Near the 

 summit the continuity of this escarpment is broken, and we find a narrow 

 recess of which the mouth faces west. It is on the two flanks of this recess 

 that the concrete occurs, occupying nearly the highest level in the neigh- 

 bourhood, which, from the figures given on the Trigonometrical Survey map 

 must be some 560 feet above the level of the Ran. In the glens of Bela 

 these deposits lie, as noted, at a high level. On the northern flanks of the 

 Habo Hills the principal part lies on the southern slope of an outlying scarp

 but the local pronunciation, as given by Mr. Wynne's names, is often very different, unaccent- 

 ed a being pronounced as a short u, and d, I and r being often interchangeable.
