persons with a light complexion, twins, and particularly all who had the mishap to be born feet foremost. For that reason Baganda women were at pains, whenever they passed the graves of any such persons, to throw sticks or grass upon them; “for by so doing they thought that they could prevent the ghost of the dead from entering into them, and being reborn.” Hence the mounds which accumulated over these graves became in course of time large enough to deflect the path and to attract the attention of travellers. It was not merely matrons who thus took care not to become mothers unaware; the same fears were entertained and the same precautions were adopted by all women, whether old or young, whether married or single; since they thought that there was no woman, whatever her age or condition, who might not be impregnated by the entrance into her of a spirit.(53) In these cases, therefore, the throwing of sticks or grass at graves is a purely defensive measure; the missiles are intended to ward off the assaults of dangerous ghosts. Similarly we are told that in Madagascar solitary graves by the wayside have a sinister reputation, and that passers-by, without looking back, will throw stones or clods at them “to prevent the evil spirits from following them.”(54) The Maraves of South Africa, like the Baganda, used to burn witches alive and to throw stones on the places of execution whenever they passed them, so that in time regular cairns gradually rose on these spots.(55) No doubt with these Maraves, as with the Baganda, the motive for throwing missiles at such places is to protect themselves against the ghosts. A protective motive is also assigned for a similar custom observed in Chota Nagpur, a region of India which is the home of many primitive tribes. There heaps of stones or of leaves and branches may often be seen beside the path; they are supposed to mark the places where people have been killed by wild beasts, and the natives think that any passer-by who failed to add a stone or a stick to the pile would himself be seized and devoured by a wild animal.(56) Here, though the ghost is not explicitly mentioned, we may perhaps suppose that out of spite he is instrumental in causing others to perish by the same untimely death by which he was himself carried off. The Kayans of Borneo imagine that they can put evil spirits to flight by hurling sticks or stones at them; so on a journey they will let fly volleys of such missiles at the rocks and dens where demons are known to reside.(57) Hence, whenever the throwing of stones at a grave is regarded as an insult to the dead, we may suppose that the missiles are intended to hit and hurt the ghost. Thus Euripides represents the murderer Aegisthus as leaping on the tomb of his victim Agamemnon and pelting it with stones;(58) and Propertius invites all lovers to discharge stones and curses at the dishonoured grave of an old bawd.(59)
