moner ferns, such as Allosorus* crispus, Asplenium viride, Poly- 

 podium Phegopteris, P. Dryopteris, &c. At one place, where the 

 limestone appears, we gathered Polystichum Lonchitis, more than 

 fifteen inches in length, but in very small quantity. We also saw 

 Epilobium alsinifolium, Hieracium diaphanum and Lawsoni, Viola 

 flavicomis, and a single plant of Saxifraga umbrosa, var. crenata. 

 In a marshy spot near the junction of Maizebeck with the Tees, we 

 gathered Saxifraga stellaris in great profusion, and remarkably large. 

 Returning by Whetstone Sill, we noticed Habenaria albida, Salix 

 arenaria, Equisetum variegatum, Carex capillaris and Bartsia alpina, 

 the two last nearly a foot in height. We returned to the inn to tea, 

 and afterwards went down to the High Force ; the rocks here are of 

 basalt overlaying limestone, down which the river pours in an almost 

 unbroken fall of sixty-nine feet in height, into a dark basin, and runs 

 along a deep ravine among high perpendicular rocks. 



Several rare plants are found here, among others, Hieracium rigi- 

 dum and Lawsoni, Crepis succisgefolia, Sesleria caerulea, Poa Par- 

 nellii, Melica nutans, Potentilla fruticosa, Solidago Virgaurea, &. 

 cambrica, Carex rigida ? Geum rivale &c. ; and on the scars beyond, 

 we gathered Arbutus Uva-ursi. This has hitherto been considered 

 the only locality for Poa Pamellii, which we found growing abun- 

 dantly on the rocks, but scarcely come to perfection. 



On the 1st of 7th Month we started early for High-cup Scar, tak- 

 ing Falcon Glints on the road, the upper series of which we partially 

 explored, but found little fresh. On the way thither we gathered a 

 few specimens of the rare Hieracium Lapeyrousii, and near Cauldron 

 Snout discovered a fresh locality for Poa Parnellii. 



Leaving Cauldron Snout to the right, we followed Maizebeck from 

 its junction with the Tees ; along its banks we gathered Botrychium 

 Lunaria, Myosotis repens, Saxifraga stellaris, &c. Taking a branch 

 of Maizebeck to the left, and following it almost to its source, we 

 crossed over Scordale Head, and visited Gaskill tarn on its summit, 

 a body of water of considerable extent, but affoiding no plants wor- 

 thy of notice. Hence we descended towards the head of High- cup 

 Scar, an enormous opening \^ the mountains of about one thousand 

 feet in depth, nearly surrounded by perpendicular basaltic crags, and 

 resembling in shape the hull of a large vessel : the lower part is chiefly 

 covered with debris interspersed with patches of short grass; it is up- 



* In this, and a few other instances, we have, with permission, altered the nomen- 

 clature of the ferns. — Ed.
