In the island of Mindanao, one of the Philippine group, the heathen Manobos called the thunder the “speech of the lightning,” and regarded the latter as a kind of wild animal, so that whenever the lightning struck the earth or a tree they believed that the animal had buried its teeth in the spot. They therefore looked upon any stone implement found there as one of these teeth.[220] The ancient stone hammers found in Japan are called _rai fu seki_, “thunderbolts,” or _tengu no masakari_, “battle-axes of Tengu,” the warder of the heavens. Other stone implements bear the name “fox-axes,” or “fox-planes.” These peculiar designations are employed because the fox is a symbol of the devil, and the stone axes are regarded as weapons of the devil. Of course this in no wise prevents their use as amulets or medicinally; indeed, their powder is thought to be an especially effective remedy for boils and ulcers. Many such stones may be seen in the temples, where they are carefully preserved and shown to the pilgrims who visit the different shrines.[221] Even at the present day, the superstitious belief in the magic properties of the prehistoric stone implements still survives among some of the Scandinavian peasants. They believe that these offer protection against lightning, and they are very unwilling to part with them. In some regions the stone axes or arrow-heads are supposed to afford protection against lightning, and they are occasionally used to relieve the pangs of childbirth. In the latter case they are placed in the bed of the suffering woman. Another curious use to which they are put is as a cure for an eruptive disease of children. Here the flint is struck sharply with a piece of steel, so that the sparks fall upon the child’s head.[222] This gives us an added proof of the association of these stone axes, etc., with fire and with the lightning flash. The Burmese celts or stone hatchets are frequently of jade and differ from those usually met with in Europe and India, in that they are provided with a chisel-edge instead of a double-sloped cutting edge. An interesting account of the superstitions connected with these implements is given by Mr. Theobald,[223] from whom we quote the following passage. It will be noted that the Burmese ideas are in almost exact accord with those current in Europe. The Burmese call these implements _mo-jio_, thunder-chain or thunderbolt, and believe that they descend with the lightning flash, and, after penetrating the earth, work their way back by degrees to the surface, where they are found scattered about the fields among the lower hills, usually after rain, or on removing the crops. The true _mo-jio_ is supposed to possess many occult virtues, and it is not common to find one which does not show signs of having been chipped or scraped for medicinal purposes.
