Another of these instruments expanding towards the edge, and apparently adapted for insertion in a socket, is shown in Fig. 42. It is made of hone-stone, and the flat butt is the result of a natural joint in the stone. It was found at North Burton, in the East Riding of Yorkshire, and is in the Greenwell Collection, where is also a celt of greenstone much like Fig. 41, found in a barrow with a burnt interment on Seamer Moor, Yorkshire; and another of the same class, 3 3∕4 inches long and 2 3∕4 inches wide, also from Seamer Moor. A third specimen, rather smaller, was found in a barrow at Uncleby, Yorkshire. One of greenstone, 2 1∕2 inches long, and nearly triangular in outline, was found near Keswick, and is in the Blackmore Museum. A longer adze of greenstone, considerably curved in the blade, lay in company with various implements of flint in some sand-beds near York.[324] In the Mayer Collection at Liverpool is a celt of clay-slate, 4 inches long and ground at the edge, found at Toxteth. In the collection of the late Mr. J. F. Lucas, of Fenny Bentley Hall, near Ashbourne, were two celts (5 1∕2 and 7 inches) of the same type as Fig. 35, but more adze-like in character, and formed of felstone. They were found on Middleton Moor, and at Wormhill, near Buxton, Derbyshire. In my own collection, is a greenstone celt with the sides sharp and nearly parallel, 7 1∕2 inches long and nearly 3 inches broad, with a semicircular edge partly ground, found at Shrub Hill, Feltwell, Norfolk. |97| I have also a large specimen in form more resembling Fig. 23, six inches long. It is ground at the edge, which is nearly semicircular, and along the sides. It was found at Thurston, Suffolk, and is formed of a piece of tough mica-schist, with garnets[325] in it, a material, no doubt, derived from the Glacial beds of that district. Another from Troston, in the same neighbourhood, is formed from a rough fragment of micaceous grit ground to an edge at one end. In Scotland some wedge-shaped blades of granite, exhibiting traces of a very small amount of artificial adaptation, have been found. Two such, from Aberdeenshire, described as axes, have been figured.[326] The small stone celts found in Orkney,[327] though tolerably sharp at the edge, are described as rough on the sides. * * * * *
