Bachowy, which was interpreted to mean " Little rushing water," a name ain- 

 gularly descriptive of its appearance and character. It falls into the Wye imme- 

 diately below the railway bridge; and its course upwards had to be followed 

 for about a mile and half. The path lay along a narrow mountain glen. Down 

 below, to the left, foamed and dashed the Bachowy. 



Now wiucl we up the gleu, and hear below 

 TLc daohiug tonent in deep woods concealed. 



Opposite rose a high bold hill, the hill of Garth, clothed on its slopes with 

 luxuriant woods of oak, and looking back over the Wye, the Kpynt range of 

 mountains came the more into view the higher the path rose. 



A considerable portion of the Trewern Hill has been recently inclosed. 

 The wire fence— that spider-like web of advancing civilisation— has spread over 

 its slopes. A fresh plantation of young larch on this side had taken the place 

 of the oaks as it so frequently does in South Wales. Larch grows more quickly 

 into money and is very valuable for colliery purposes. 



The glen grew narrower and the path steeper and more difficult as 

 the visitors proceeded, and 



"Not without frequent pause, as ever new, 

 Some glorious prospect opens to the view." 



On reaching the upper end of the glen they saw beneath them a deep, narrow, 

 rocky chasm, clothed with luxuriant foliage on both sides : half way down 

 this chasm and almost closing it up was a bare green promontory. This was 

 the Craig-y-pwll-ddu— the rock of the Black Pool,— to which they were bound. 

 The descent to it was by no means easy : but was at length accomplished in 

 safety ; and all the party assembled on the little table-land of turf and rock, 

 the very pefection of a spot for a pleasant pic-nic. But where, all this while, 

 was the expected rain ? No signs of it were to be seen. The freshest of moun- 

 tain breezes swept up the glen, the sun shone out as bright, and the air was as 

 clear, as heart could wish. The turf was dry ; and the wild thyme was in its 

 gayest bloom : wild strawberries lurked in the crevices of the rocks ; and the 

 pretty tormeutil (PotentiUa tormentillaj studded the verdant carpet, on which 

 the travellers were not unwilling to rest awhile. 



Advantage was taken of this interval to give a brief account of the Geolo- 

 logical features of the place. It was told how Murchison had studied the district 

 and given a section of its rocks in his great woik, ''Siluria." He had shown 

 that the stream here separates the Upper and Lower Ludlow rooks. The 

 massive rock they were then upon was seated in the middle of the glen, and 

 blocked up the stream, causing the waterfall below. It was a mass of Ludlow 

 rock, and jwobably a landslip from the hill of Trewern which they had coma 

 down. The hill of Trewern was a continuation of the Bigwn Hills, and the 

 chief formation of the range was the Upper Ludlow rocks, but over them, on the 

 top and the southern side, the Old Rtd-Sandstone rocks appeared. This range 

 will ever be remarkable for having first clearly shown to Sir Roicrick Murchison 

 the passage downwards from the Old Ked ,Sa.ndstone to the older rocks buueath
