elevation with Brackens, Pteris aquilina, which, by their 
changing in September and October from a bright to an olive 
green, and afterwards to a russet brown, contribute to that 
autumnal colouring which is so much admired. The Stone fern, 
Pteris crispa, (Cryptogramma of Hooker) inhabits 
higher and more rocky situations. Asplenium 
Adiantum-nigrum is rooted in Castlehead rock, and near Low 
Wood Inn. Hart's tongue, Scolopendrium vulgare, in rents 
of limestone rocks in Westmorland, and at Calder Bridge;
