Mr. Horner on the Mineralogy of the Malvern Hills, 301 



conglomerate, of a dark brown colour, composed of felspar, steatite, 

 and calcareous spar, iwited by a ferro-argillaceous base, and con- 

 taining some minute specks of a greenish yellow substance, in 

 diverging fibres, which is probably actynolite. The rock is attracted 

 by the magnet. 



§ 38. In a lane at the foot of the Herefordshire Beacon, on the 

 ^western side, I found a vein of red hematite, passing through a rock 

 consisting of red felspar and quartz, partially decomposed. 



§ 39. The next height to the south of the Herefordshire Beacon 

 is Swinnit-hill.* The upper part of this hill is composed of a granite, 

 that is more distinctly characterized as such, than the greater part of 

 those found in the Malvern Hills: still, however, it is very different 

 from an Alpine granite, the mica is in minute specks, and there is also 

 a very small proportion of it. In the lower part of the eastern side 

 of the hill, the rock has been excavated to a considerable depth at 

 Castle Morton quarry ; it consists chiefly of hornblende, with a little 

 reddish white felspar and quartz, and in some places it contains 

 pyrites. Am(5ng aheap of large blocks, that had been recently got 

 out of the quarry, I observed this rock penetrated in many places by 

 veins consisting of flesh red felspar and grey quartz : when the vein 

 was narrow, these were the only ingredients ; but where it became 

 wider, silvery mica also formed a component part of it, and in some 

 places it was accompanied with steatite. I was prevented from exa- 

 mining the spot from whence these blocks were taken, in conse- 

 quence of a heavy rain having, a few days before, washed down so 

 much earth from the upper part of the hill, as to fill up the place 

 where the quarriers had been at work. 



§ 40. About a quarter of a mile further south, I found a schistose 



* I write the name of this hill, as it is pronounced by the country people. I have not 

 seen it in any map, nor in the county history.
