126 TWO DAYS IN WENSLEYDALE. 



the true Jtiivlatile of Swartz ; (distinct specifically from the plant given 

 under that name by Brueh and Schimper, which is the H. irriguum of 

 Wilson's forthcoming Avork ;) and on the rocks within reach of the spray, 

 Collema multifulum of Scopoli, {C. marginale, Huds.,) and Endocarpon lachneum. 

 On the miniature scars that margin the stream below, a curious form of 

 Origanum vulgare, with pale flowers, green bracts, and prominently exserted 

 stamens, occurs, amongst plenty of Scahiosa columbaria, and Hypericum 

 diihium. 



In the afternoon we visited some of our friends who reside at Thoresby, a 

 mile or two eastward. In fields below Carperby grow Allium vineale and 

 oleraceum; and on Ash trees by the side of the footpath, Parmelia scortea and 

 pallescens. On the hill-side above Thoresby, Bolton castle, founded by the 

 Scropes in the reign of Richard II., celebrated in history as one of the 

 prison-houses of the unfortunate Mary of Scotland, occupies a commanding 

 position. Though besieged and taken in 1645, by the Parliamentary army^ 

 it has suffered comparatively little deterioration, a portion being still in- 

 habited, and {^^ Sic transit gloria mundU") one of the principal rooms upon 

 the story converted into a tinner's shop. With one of our friends as guide, 

 we visited the castle, and examined it thoroughly throughout, ascending 

 even to the very roof; whence we brought away, as memorials, specimens of 

 Poa suhcarulea and Achillcea millefolium. On the hill-side above the castle, 

 Hieracium strictum had been supposed {vide " Supplement to the Yorkshire 

 Flora") to occur. Having been favoured with explicit directions to the 

 station, I mounted up to the place, but could find only H. vidgatum ; and 

 have since seen reason to believe that an accidental transposition has taken 

 place, and that the locality for the strictum is in reality Grizedale, in West- 

 moreland; so I consoled myself with gathering Sesleria ccertilea, and rejoined 

 my companions at the village. In the evening we returned again to 

 Carperby, 



We had already compiled a list of between three and fovir hundred sj)ecies 

 of flowering plants and ferns, and should have much liked to have prosecuted 

 our researches further; to have seen for ourselves the striking phenomenon 

 of the occurrence of Armeria maritima (normally a littoral species, but occa- 

 sionally growing also in alpine situations inland) in luxuriant profusion at 

 Nappa, elevated only about seven or eight hundred feet above the level of 

 the sea ; to have trodden in the footsteps of the older explorers before 

 mentioned, and verified the stations which they have placed on record for 

 various boreal species ; and to have endeavoured to trace out the ascending 

 termini of southern species, amongst the romantic and picturesque scenery 

 of Upper Wensleydale. I was, however, on the other hand, desirous of 

 reaching home again next evening; so we parted from our kind and hos- 

 pitable entertainers, and crossing the intervening moors by way of Hart-leap 

 well, managed to arrive at Richmond, just — and only just — in time for the
