138 The original of Fig. 84 is in the Greenwell Collection, and was found near Truro. It is of serpentine, with an oblique edge, and seems to have been formed from a pebble with little labour beyond that of sharpening one end. Though much flatter on one face than the other, it would appear, from the slanting edge, to have been used as an axe and not as an adze, unless indeed it were a hand-tool.

A beautiful adze formed of chalcedonic flint is shown in Fig. 84, kindly lent by the Society of Antiquaries of Scotland. The original was found at Fernie Brae, Slains, Aberdeenshire. It is 7 inches long, and of nearly triangular section. A somewhat similar adze of greenstone was found at Little Barras, Drumlithie, Kincardineshire. I have a flint adze (5 inches) of much the same character, but not so flat and blunt at the butt-end, and ground at the edge only, which was found in Reach Fen, Cambs. It is shown in Fig. 35 at page 92.

Another peculiarity of form is where the edge, instead of being as usual nearly in the centre of the blade, is almost in the same plane as one of the faces, like that of a joiner's chisel. An implement of this character, from a "Pict's castle," Clickemin, near Lerwick, Shetland, is shown in Fig. 85.

It was presented to me by the late Rev. Dr. Knowles, F. S. A. The material appears to be a hard clay-slate. The form is well adapted for being mounted as an adze, much in the same manner as the nearly similar implements in use by the South Sea Islanders. A New Zealand adze of precisely the same character has been figured.

Sometimes the edge of a celt, instead of being sharp, has been carefully removed by grinding, so as to present a flat or rounded surface.
