Long after this was forgotten the wheel remained, as has the gallows with us, as the instrument for the execution of criminals. In Germany, even in cases of decapitation, the person executed was placed on a wheel and his head on a pole, when separated from the body. The last instances of breaking on the wheel were in the first forty years of this century. The fact of the use of the wheel as a means of execution continuing so many hundreds of years after the worship of the sun-god had ceased, and of the gallows with us, for the same purpose, is a very curious and instructive illustration of the persistence of customs of which the original significance is absolutely lost. XII. Holes. In the village churchyard where as a boy I often played, is a tomb, built up to the height of about five feet, with a slate slab let into the south face, on which is an inscription. In this slab is a hole, and it used to be said among the village boys that any one who looked in through this hole and knocked at the slate would see the dead man within open his eyes. Often have I and my brother peeped in and knocked, but the experiment failed, because, when the eye was applied to the hole, it excluded external light. [Illustration: _Fig. 43._--HOLED TOMBSTONE, BURGHEAD. (_From Mitchell’s “The Past and the Present.”_)] The monument is still where it was, and is in the same condition. Whether boys still knock and look in I do not know.[44] Curiously enough, a somewhat similar practice exists at Burghead, about nine miles from Elgin, which is described by Professor Mitchell in his “Rhind Lectures,” 1880. He says: “There is a memorial slab built into the wall of the burial-ground, called the Chapel Yard, at the south-east corner; it is 35 inches high by 20 inches wide; close above it, and also built into the wall, there is a hewn lintel-like stone, 37 inches long by 1½ inches thick. On the narrow exposed face of this stone there is no sculpturing. “The woodcut shows the position on the cradle stone (as it is called) of a cup-like hollow, which is quite round 2¼ inches in depth. This hollow has been produced by the children of Burghead, who are in the habit of striking the spot with a beachstone (which is also represented in the woodcut), and then quickly putting their ears to the place, when the sound of a rocking cradle and the crying of a child are said to be heard, as if coming from a cavern deep under ground. I am told that during last century the stone was not visited by children, but by women, who believed that they were to become mothers if they heard the rocking of the cradle and the crying of the child after tapping on the stone.” What is certainly a curious coincidence is that the pre-historic rude stone ossuaries, dolmens or cromlechs, have very frequently in like manner a hole worked in them.
