name, where the greatest number of flints is found, seems to de- 

 note connection in days gone by with the adjoining nunnery at 

 Holystone. Wreigh Hill rises on the south, where formerly 

 stood a considerable village, which on Wednesday, May 25, 1412, 

 was pillaged and burnt by the Scotch freebooters, and again in 

 1665 it was depopulated by the plague. On the opposite bank 

 of the Coquet is the old village of Holystone, reputed to have 

 been one of the places visited by Paulinus the Bishop on an 

 evangelizing tour, where, it is said, he baptised 3000 Saxon con- 

 verts, Easter 627. Plainfield Moor, which is part of Farnham, 

 is the spot where James, the ill-fated Earl of Derwentwater, 

 raised the standard for the Pretender in the rising of 1715. 



The following is a list of the flints, indicating their nature and 

 colour : — 1, thumb flint or scraper, dark slate ; 2, oval arrow head, 

 dark slate ; 3, oval arrow head, light drab : 4, thumb flint, dark 

 slate ; 5, arrow head, lower part fractured, dark slate ; 6, arrow 

 head, very light slate, as if bleached ; 7, arrow ^head, very light 

 slate, as if bleached ; 8, arrow head, dark slate ; 9, knife or flake, 

 light brown ; 10, barbed arrow head, light slate ; 1 1, arrow head, 

 fine dark slate; 12, knife or flake, light slate ; 13, arrow head, 

 nearly white, as if bleached ; 14, portion of spearhead, fractured 

 at lower part, dark flint (beautifully chipped) ; 15, thumb flint, 

 (has been the outside chip), dark slate ; 1 6, barbed arrow head, 

 fractured, light red brown.

Since writing the article for last year's Proceedings I have 

 been fortunate enough to find at or near Berwick the following
