The ahove exhibits the general state of the case in the neighbourhood 

 of Bagh and Rajpoor. To the westward there is

ing taken place. An instance will be described 

 in the following pages south of Kawat, and another on the east side 

 of the Deva inlier, where the traps appear to have accumulated against 

 a previously denuded cliif of cretaceous beds. It is true that both 

 instances may be due to faulting, but, for reasons which will be explained, 

 this appears less probable than the hyphothesis of previous denudation 

 Nevertheless in the immediate neighbourhood, in both cases, the traps 

 rest, to all appearance conformably, upon the undenuded surface of the 

 Bagh beds, shown to be undenuded by the persistence of the same bed 

 beneath the bottommost flow of trap, and in these and every other case, 

 the Yerj close paraReHsm, i. e., the general conformity in dip of the two 

 series, is remarkable. Although considerable disturbance has taken place 

 (especially south of Kawat), the greater portion at least is palpably of 

 post-trappean date. In one or two local cases the Bagh beds had been 

 apparently disturbed in pre-trappean times, but such instances are very rare. 

 Even where the greatest amount of denudation has taken place, 



it presents no appearance inconsistent with the

always irregular, such as has leit the surface m 

 hills and valleys. It is always local, never general. Thus, even in this 

 instance, we have strong evidence that the outpouring of the traps, even 

 when they rest on unquestionably marine beds, was in itself subaerial, . 

 and not, as some writers have supposed, submarine. 



To sum up, the traps rest nearly conformably upon a locally denuded 



surface of the cretaceous beds, the two series exhi- 



logical break" betvveen biting general conformity. There is therefore no 



ag ecb an laps. evidence of a great geological break between them. 



It should be added that similar local denudation has taken place between
