in damp places near the roadside, Lotus major and Glyceria 

 jo/ic«^a (300 yards) . 



" The cuhninating summits of the line of watershed between 

 the Swale and the Arkle, Rogan's Seat and Water Crag, attain 

 respectively 2.207 and 2184 feet. To these, from the village of 

 Gunnerside, runs up a steep gill about six miles in length, in 

 which are some of the most productive leadmines of the Auld 

 Gang Vein. They have been worked from a remote antiquity, 

 possibly from the period of Roman domination, when Cartismandua 

 swayed the sceptre of Isurium, and Severus, over-wearied, lay 

 down to die at Eboracum. We walked up the course of this gill 

 for some distance, but had not time to follow it out to its ex- 

 tremity. Immediately above the village (300 yards) we came 

 upon Saxifraga hypnoides, and whilst still about the same level, 

 Equisetum Telmateia, Polypodium Phegopteris, Habenaria chlo- 

 rantha, and Seligeria recurvata. The main limestone declines 

 somewhat from Calvey to Water Crag, and here does not much 

 exceed 500 yards. It shoAvs itself along the edge of the moor 

 in a line of scars. Climbing up to these we found, on the edge 

 of a stream that flows from the foot of the cliff, Carex fulva, 

 Bartramia calcarea, and Hypnum commutatum, var. condensatum. 

 Upon the scars grow Galium sylvestre, Sesleria cmi'ulea, Juniperus 

 communis, Primula vulgaris, Arabis hirsuta, and in a place where 

 a rivulet trickles down a break in them, we noticed Epilobimn 

 alsinifolium, with Chrysosplenium oppositifolium, Poa trivialis, 

 and Agrostis alba. Upon the top of the main limestone, by the 

 side of a little pond, are Callitriche verna, Montia fontana, and 

 Ranunculus repens ; on the gritstone edge above (550 yards), 

 Salix caprea and Pogonatum alpinum ; and on the very summit 

 of the moor, Rubus Chamamorus. 



" From the leadmines, everywhere about which is a remark- 

 able profusion of Arenaria verna, but no Thlaspi alpestre that 

 we could see, as at Hurst, Woodhall, and Malham, we struck 

 over a spur of Rogan's Seat in the direction of the main dale, 

 and reached just at the corner of the angle before spoken of, in 

 which Cragpot Hall is situated. On the edge of the fell over 

 Swaledale proper is Sphagnum molluscum, and on its slope Carex 

 curta, C. ampullacea, and Rumex sanguineus, the latter at an 

 elevation of upwards of 300 yards. In the woods by the road- 

 side, at about the same level, are Circcea lutetiana, Origanum
