SANDSTONE NEAR HALAI AND TAKONDA. 51 



level. It divides two streams : one the main source of 

 the Haddas, running from close to Takonda ; the other a 

 side valley, up which is the pass to Takonda from the 

 Haddas. This sandstone cap, the top of which is far 

 below the base of the sandstone on the hiUs at both 

 sides, extends to the north beyond the termination of the 

 sandstone on the plateaux. It is thus clear that the 

 somewhat abrupt northern termination of the sandstone 

 on the plateaux is not due to faulting, but the intervening 

 ridge has much the appearance of being let down by two 

 great faults, one along each of the valleys at its sides. 

 It may however owe its existence to the sandstone 

 being deposited on a very uneven surface, and filling 

 a pre-existing hollow in the metamorphic rocks at 

 this point. 



There is, however, another instance south of Takonda, 

 in which the sandstones appear to be thrown by a fault. 

 On the hill, just south of the village, there is a thin cap 

 of sandstone resting on metamorphic rocks. Immediately 

 south of this is a deep valley, on the opposite side of 

 which the sandstones appear in a narrow terrace, about 

 500 feet lower than their position on the north side, 

 although they are horizontal in both places. The isolated 

 block, already mentioned as occurring to the west of the 

 road from Senafe to Eahaguddy, is a third case. All of 

 these may be due to deposition on the irregular surface 

 of the crystalline rocks, but in the two former instances, 

 at least, faulting appears more probable. As a general 

 rule, however, the absence of all signs of geological dis- 

 turbance in the sandstones is remarkable, since they
