of older date than the overlying strata ; still, during and subsequent to 

 the formation of this peculiar rock, chemical action must have been very 

 active. Some of the discontinuous layers in this covering rock are entirely 

 made up of debris of the trap and granite, in which the felspar seems to 

 have reconstituted itself in a crystalline form as the binding material. At 

 this point over Sungrumpoor there is, at three feet under the junction 

 surface of the granite, an irregular discontinuous vein, averaging from 

 3 to 5 inches thick ; it was evidently open to the surface for it contains 

 sand, but its connection with the surface is not traceable on the present 

 section ; its principal filling in is limestone, in every respect of color, tex- 

 ture and even its mode of weathering like the typical Tirhowan rock, 

 but through it, besides a few strings of sand, are thin seams of perfectly 

 formed granite, a hard equal mixture of black mica, clear pink felspar, 

 and hyaline quartz, not in the least resembling any of the granitic rocks 

 around, which are very undecided and variable in texture and composi- 

 tion, these granite strings sometimes fill cracks across the limestone vein, 

 sometimes run in strings, from an inch wide to a paper thinness, parallel 

 to the sides : it has not in the least the aspect of a rock reformed from 

 debris; it has all the freshness and the imperishable aspect of the strongest 

 granite. Its position and comparative composition seemed to me inex- 

 plicable but by origin from solution. 



On the N. W. side of Chutterkote hill the granite junction is only 



about 50 feet from base, and on the east side it is

below the surface : this hill however is as high as 



the rest, the lower 200 feet being of Tirhowan limestone and the rest of 

 sandstone, all quite horizontal — the junction rock has not however alter- 

 ed, it keeps on under the limestone without any change, and in this posi- 

 tion one would naturally take it for the bottom beds of the limestone ; the 

 slope of the granite surface is so small as not to make apparent any 

 obliquity of junction. 



But even from this section we have the fact of its underlying the lime-
