Chumpawut, Dhee, Almorah, Shaee Debee, Dooara Hath, Palee, Dhoeet, 

 and Kunyoor. They are situated in the zone of minimum elevation, and a 

 line passing through them has a direction of North 60° West, the same 

 as that of the strata and zones of different elevation. West of the 

 Ganges, no such beds are found, unless we suppose the Choor granite, 

 (which is certainly on the prolongation of this line) to be one, and then 

 it will be the only one. Another anomaly which the granite of the 

 Choor presents is, that it occupies the highest point in all the mountain 

 tract, south of the zone of greatest elevation, whereas the eastern beds 

 are situated in the lowest ground. A third difference is in the charac- 

 ter of the rock, which in the case of the Choor granite, is highly crystal- 

 line ; in most of the others, earthy and decomposing. Yet it must be 

 confessed, that they present some differences of aspect in this respect, 

 and that at Chumpawut, Dhee, and Almorah, very hard and crystalline 

 granites are procurable, though at the two latter places in limited 

 quantity. 



301. The grain of the veinous granites is, as has been often remarked, 

 large ; in variety of composition too, they form a singular contrast to the 

 uniformity which distinguishes the gneiss. In this respect, they also 

 differ from the beds of granite, which are strikingly alike in mineral 

 composition, colour, and size, and arrangement of grain. In these 

 particulars, the Choor granite is almost precisely that of Almorah, though 

 separated by such a wide interval. What distinguishes this granite at 

 first sight is, its porphyritic structure, and it evidently contains two 

 distinct varieties, if not species of felspar.* This variety is seldom 

 found in a crumbly decomposing state. The only other well defined 

 type is that which is so remarkable for its rapid disintegration, in which 

 the ingredients appear to be united in the usual irregular manner. 

 This contains a large portion of white opaque felspar, and it is well 

 distinguished by its granite boulders, the true nature and history of 

 which have been so well laid open by Dr. Macculloch. 



302. Smaller veins have not been observed to affect the appearance 

 of the including rock, but the vein at Wangtoo, the only large one 



* The existence of several mineral species hitherto confounded under this title, has 

 been now clearly established, and I anxiously look forward to a period of leisure, 

 when 1 may submit the different granites to a particular examination with reference 

 to this point.
