Some of the thicker ridged flakes, i.e., triangular in 

 section with a single ridge formed b}' two facets on the 

 convex face, have also been formed into boring tools. In 

 these cases the edges and opposite faces of the flake have 

 been chipped away, especially near tlie pointed end, so 

 that the cutting edges are at opposite angles. These 

 tools ajjpear better adapted for boring continuousl}- in 

 one direction. As the Culbane examples appear to be 

 rather an interesting and unusual tj'pe, a figure is given 

 below of a specimen in the Darbishire collection. (See

 from Culbane of the long, narrow chisel t}'pe of celt, with 

 somewhat straight sides. One specimen, 6 inches long 

 and i^ inches wide, roughly chipped to shape, has the 

 cutting edge formed b)' the intersection of two facets — a 

 characteristic feature of the "Kitchen-midden type," 

 described b\' Coffey and Praeger (04) in their paper on 

 the " Larne Raised Beach." Another cxamj^le, finches 

 long and i.^, inches wide in the middle, has been dressed
