A clever workman he must have been who made this wonderful knife. But such beautifully wrought implements are very rare. Only one similar knife—found in a barrow at Aldro—was known to its discoverer, and he had himself superintended the excavation of no fewer than two hundred and eighty-eight barrows. The weapons and tools which have been buried with their owners are more commonly of the rougher types figured on the opposite page. They include knives, chisels, spear heads, saws, and arrow heads, all made from flints by the processes of chipping and flaking, with hammer heads, picks, needles and daggers of bone. Compare the figures A and B given on page 9 with the illustration of the antlers of a red deer on page 7, and see how cleverly the hammer head and the pick have been fashioned. Equally clever has been the adaptation of a bone in the making of the very primitive dagger figured at D on the same page. But in this case it has been not the antler of a red deer that has been brought into use, but the thigh-bone of a man. [Illustration: FLINT IMPLEMENT AND WEAPONS. A. Chisel from Aldro (1/1). B. Barbed arrow head from Grimston (1/1) C. Javelin head from Duggleby Howe (1/1). ] So far we have spoken of weapons and implements of bone and of flint. Others were then in use made of whinstone and greenstone, such as the axe heads figured overleaf. Notice the different arrangement of the cutting edge in these two implements, and notice also that in the first one the hole intended for the insertion of a wooden handle has, for some reason or other, not been finished. Perhaps the maker was killed before he had time to finish it, or perhaps he grew tired of his work and threw it away. At any rate this unfinished adze head was found loose on the surface of the ground, and not buried under a howe as was the other.

May we not justly call their makers MEN OF THE STONE AGE? They lived before man knew how to dig metals from the earth, and how, having obtained them, to melt and mould them to his wish. But besides these weapons which have lain buried with their owners for some thousands of years, there are yielded up by the barrows earthenware vessels of different sizes and shapes. Some, like that shown below, are wide-mouthed and have a thick rim; others are narrower, and their rim is not thickened. Then others have an overhanging rim; and others, again, are small, only an inch or two in height, and have from two to six holes perforated in their sides. All are marked with simple patterns, made by pressing the pointed end of a stick or the thumb-nail into the moist clay, or by pressing round it a twisted thong of hide. There has been no glazing and no attempt to make use of artificial colour. [Illustration: FOOD VESSEL FROM A BARROW ON ACKLAM WOLD (1/2).]
