of birch. To reach Henhole, which is perhaps the finest, or at any rate the rockiest glen of the three, from Dunsdale, the ridge on the west has to be crossed, as the glen sweeps round the west end of the highest ridge so as almost to join the Langlee glen at its head. Of the well-heads of the upper part of these ravines, from 1500 to 1800 feet, the following are the principal plants:—
| Caltha palustris. | Lychnis flos-cuculi. | |
| Sedum villosum. | Taraxacum palustre. | |
| Saxifraga stellaris. | Carduus palustris. | |
| Epilobium obscurum. | Galium palustre. | |
| alsinifolium. | Juncus effusus. | |
| Myosotis repens. | lamprocarpus. | |
| Montia fontana. | Carex pulicaris. | |
| Stellaria uliginosa. | panicea. | |
| Pamassia palustris. | vulgaris. |
Amongst the debris there is abundance of Allosorus crispus, but the only other rare fern, Asplenium viride, is more difficult to find. The more note-worthy montane plants of the crags are—Sedum rhodiola, Hieracium argenteum and pallidum, Rubus saxatilis, Poa Balfourii, Saxifraga hypnoides, and Epilobium angustifolium. The streams of these ravines join at Southernknow, 3 miles below which is the finest of the low-level Cheviot water-falls, Heathpool Linn. On the south is a dry bell-shaped hill, 1700 feet in altitude, and on the north a porphyritic crag sweeps down suddenly into the stream, contracting it for a space of 30 or 40 yards into a narrow rocky channel. The rocky banks are overgrown by bright-green shade-loving mosses, and over-shadowed by ash and elm; and a natural wood of oak, rowan, and birch extends along the slope of the southern hill. Here grow Dianthus deltoides, Euonymus europaeus, Poa nemoralis, Epilobium angustifolium, Hieracium argenteum and crocatum. At Kirk-Newton the Glen is joined by the Beaumont, which rises on the Scotch side of the Cheviot mass, and sweeps round it in a curve past Yetholm and Mindrum. The Kilham Hills, which are enclosed in the angle between the two streams, are a series of rounded tors not exceeding 1000 feet in height, dry,
