129. How stone implements are made. What was the process by which these stone implements were made? The artifacts bear witness directly to two or three different operations, separate or combined, and to a great development of the process. As above stated, Tasmanians, after they became known to Europeans, made stone implements as they needed them, giving to a stone a rude adaptation to the purpose by chipping off a few flakes. Short sharp blows were struck by one stone upon another. The blow must, however, fall upon just the right spot or it would not produce the desired result. Therefore the flakes were often thrown off by pressure. A stick or horn was set against the spot where the force should be applied, and braced against the breast of the operator, while he held the stone between his feet. This latter operation is described as used by the Mexicans to get flakes of obsidian.206 By carrying further the process of chipping or pressing the stone could be shaped more perfectly, and by rubbing it on another stone it could be given a cutting edge. The rubbing process could also be applied to the surface to make it smooth instead of leaving it as it was after the flaking process. The processes of striking and pressing were also combined. The pebble was broken by blows and the pieces were further reduced to shape by the pressing process. Different devices were also invented for holding the stone securely and in the proper position. Skill and judgment in perceiving how and for what purpose each pebble could best be treated was developed by the workers, and division of labor arose amongst them as some acquired greater skill in one operation and others in another. The operations of pressing and striking were also made complex in order to accomplish what was desired. A sapling was cut off so that the stump of a limb was left at the bottom of it. It was set against the spot where the force was needed, and a blow struck in the crotch of the limb caused the chip to fly. This apparatus was improved and refined by putting a horn tip on the end point of contact. Another device was to cut a notch in a tree trunk, which could be used as a fulcrum. A long lever was used to apply the pressure to the stone laid at the root of the tree, or on the horizontal space at the bottom of the notch.207 These variations show persistent endeavor to get control of the necessary force and to apply it at the proper point with the least chance for error and loss. Buckley reported about the "tomahawks" of the aborigines of Victoria, that the stone was split into pieces, without regard to their shape, but of convenient thickness. A piece was rubbed on rough granite until "it is brought to a very fine thin edge, and so hard and sharp as to enable them to fell a very large tree with it." The handles are "thick pieces of wood, split and then doubled up, the stone being in the bend and fixed with gum, very carefully prepared for the purpose, so as to make it perfectly secure when bound round with sinews."208 The natives of the Admiralty Islands use obsidian which is dug from layers in the ground. Only a few know the art of making axes, and they prosecute it as a means of livelihood. Skill is required especially to judge of the way in which the stone will split. The only tool is a stone with which light, sharp blows are struck.209 The axes of the Swiss lake dwellings were made from bowlders of any hard stone. By means of a saw of flint set in wood, with sand and water, a groove was cut on one side and then on the other. With a single blow from another stone the bowlder was made to fall in two. By means of a hard stone the piece was rudely shaped and then finished by friction. A modern student has made such an ax in this way in five hours. Sometimes the stone was set in a handle of wood or horn.210 It will be noticed that this process was not possible until an auxiliary tool, the flint saw, had already been made. The tools and processes were all rude and great skill and dexterity were required in the operator. "Lafitau says the polishing of a stone ax requires generations to complete. Mr. Joseph D. McGuire fabricates a grooved jade ax from an entirely rough spall in less than a hundred hours."211
130. How arrowheads are made. As to arrowheads, "there are a dozen or more authentic reports by eye-witnesses of the manufacture of arrowheads in as many different ways."212 The California Indians broke up a piece of flint or obsidian to the proper-sized pieces. A piece was held in the left hand, which was protected by a piece of buckskin. Pressure was put upon the edge by a piece of a deer's antler, four to six inches long, held in the right hand. In this way little pieces were chipped off until the arrowhead was formed. Only the most expert do this successfully.213 Sometimes the stone to be operated on is heated in the fire, and slowly cooled, which causes it to split in flakes. A flake is then shaped with buck-horn pincers, tied together at the point with a thong.214 In another report it is the stone with which the operation is performed which is said to be heated.215 In a pit several hundred flint implements were found stored away in regular layers with alternate layers of sand between. Perhaps the purpose was to render them more easy to work to the desired finish.216 Catlin describes another process of making arrowheads which required two workmen. One held the stone in his left hand and placed a chisel-like instrument at the proper point. The second man struck the blow. Both sang during the operation. The blows were in the rhythm of the music, and a quick "rebounding" stroke was said to be essential to good success.217 A "lad" in Michigan made arrowheads in imitation of Indian work, from flint, glass, and obsidian, with a piece of oak stick five inches long as a tool.218 Sophus Müller219 says of modern attempts to imitate stone-implement making that an average workman can learn in fourteen days to make five hundred to eight hundred arrowheads per day, but that no one of the best workmen has been able to equal the fine chipping on the neolithic stone weapons, although many have made the small implements on the types of the old stone age.
131. How stone axes were used. After stone axes were made it required no little independent sense to use them for the desired result. A modern archæologist used a stone ax of gray flint, with an edge six and a half centimeters long, set in a handle after the prehistoric fashion, to cut sticks of green fir, in order to test the ax. He held the stick upright and chopped into it notchwise until he could break it in two. He cut in two a stick eighteen centimeters in diameter in eighteen minutes. He struck fifteen hundred and seventy-eight cuts. At the fourteen hundred and eighty-fifth cut a piece flew from his ax.220 A modern investigator made a polished ax in eleven hours and forty-five minutes. He cut down an oak tree 0.73 meter in circumference, with twenty-two hundred blows of the ax, in an hour and thirteen minutes.221 When primitive men desired to cut down a tree, fire was applied to it and the ax was used only to chop off the charred wood so that the fire would attack the wood again. Canoes were hollowed out of tree trunks by the same process. These processes are reported from different parts of the world remote from each other.222 Without these auxiliary devices the stone ax can really be used only as a hammer, for, by means of it, the wood is beaten into a fibrous condition and is not properly cut.223 Nevertheless, the Shingu Indians cleared forests, built houses and
