ftone-ferns, the adit ftored- with that wholefome and agreeable 

 fallad, the water-crefs. 



Near this fpring are the ruins of huge rocks, beaten down by 

 florms. One is fifteen feet long, eighteen feet and fifteen inches 

 broad, and above fix feet thick ; the black Mane Ufnea, or rock- 

 hair, on the back part of it. Another, by the violence of the 

 fall, has flarted from it, and refts with one end at the bottom. 



At a fmall diftance caftward, is a third of a more remarkable 

 fize, one folid mafs, twcnty-feven feet, ten inches long, eight 

 feet broad, and twelve feet thick ; Vaccinia nigra, and Eric<e, on 

 the top. 



By the village of Fen-wick, near Kiley at Ancroft, and Norham, 

 near Berwick, is a free-ftone of a pale red colour. With the Fen- 

 wick-ilone, the priory of Holy I/land feems to have been built j and 

 with the Norbam-ft.on.e, the caftle of Norham. 



On White-fide bank, near Woofer, is a free-ftone of a light pur- 

 ple ; of a clofe grit, with fome talcy fpangles ; the ftratum three 

 feet, and the roof fix feet, thick. 



I might mention fome other quarry-free-ftones, but thefe are 

 of principal note for mechanic ufes. 



The whiteft and moft beautiful free-ftone found in detached or 

 loofe mafles, is on the eftate of William Sivinburn, Efq; at Long 

 Witton, near the village, compofed of a bright white fand, and 

 filvery micce, laced with fparry veins, which render it lefs con- 

 defcenfive to the chiflcl. It is ufed for chimney-pieces, and other 

 ornamental ftone-works.
