The leaders of psychical research allege that the survival of human personality after death has been scientifically proved, and that, under favourable circumstances, communications from the dead have been received. If this be so, might it not be said that races on a lower plane of culture are possibly more sensitive to such influences and that their belief in the activity of the ancestral spirits is therefore not wholly unreasonable? The evidence for this, however, is at present quite insufficient to satisfy most, although we think that the question is one which deserves further consideration.
Tree Spirits.—When clearing a forest to make a cultivated field, the Kikuyu people generally leave a large and conspicuous tree in the clearing. Such a [[32]]tree is called murema kiriti and is believed to collect the spirits from all other trees which have been cut down in the vicinity. We have here an interesting example of animism, the spirits so collected being most emphatically declared to be tree, and not human spirits. Now if this tree shows signs of decay and is liable to be blown down, they decide to fell it. Before taking this step, however, they sacrifice a red ram at the foot of the tree, the ram being, as usual, killed by suffocation. The tree is then cut down, and when this is done, the elders take branches from two sacred bushes, mukenya and muthakwa, and plant them on each side of the stump of the fallen tree; two elders cut the mukenya, and two the muthakwa. The elders then say “Nitukuria muti tutemeti,” which means “We pray for this tree we have cut down,” and pour the melted tail-fat of the ram over the stump, smearing the tatha or stomach contents of the animal over the trunk of the fallen tree. The wood from such a tree can only be used by a senior elder, by a very old woman, or for the making of beehives. If young people were to use this particular fuel, they would become ill or die; old people are supposed to be ordinarily immune against the operation of most curses or thahu. It is believed that when a tree is cut down the spirits leave it and settle in another big tree, and, if the above ceremonial is observed, they are not angry and do not vent their spite upon the people, or, as they say, no thahu falls upon them. If such a tree blows down, the spirits are supposed to avenge themselves on the elders, who are held responsible for not having taken the necessary precautions, and they are very apt to die.
There is great similarity between this and the lore concerning the spirit of the oak, mentioned by Professor Frazer. And, from a different point of view, it may also be considered as an example of the slaying of the divine king, expressed in terms of trees: fear that harm may befall the spirit or spirits of the tree, and the consequent ceremonial killing of the tree and [[33]]arranging for the comfortable and formal migration of the spirits to another tree, or to a new dwelling place.
The A-Kamba of Kibwezi have a similar belief: before cutting down a big solitary tree in a clearing, an elder and a very old woman must pour beer and corn at its foot. The man pours out the beer, and the woman the corn. The tree is then felled, and, taking a branch from it, they place it against another tree some little distance away, and declare that the spirit of the fallen tree will then go quietly into its new abode.
In Ukamba of Ulu, Mr Osborne states that his people told him that to fell an ithembo tree would, of course, be considered absolute sacrilege, and according to tradition it was the felling of an ithembo tree on the Iveti Hills by an official of the I.B.E.A. Co. which gave rise to the attacks by the A-Kamba on the Government Station at Machakos in about 1892.
Large trees, however, which are not ithembo trees appear to have a certain sanctity, and when, for reasons of utility or safety, the felling of such trees becomes necessary the following ceremony is practised:
The trunk of the tree to be felled is plastered with the sap of the waithu shrub as a ng͠nondu.
A small branch of the tree is broken off and placed against some smaller tree in the vicinity.
Some earth at the foot of the tree is also taken and placed at the foot of the smaller tree.
The elders then assemble with some beer at the tree to be cut down, and a little of the beer is poured out at the foot of the doomed tree, accompanied by some such prayer as—“We give this beer as a gift to the Engai, if one lives here, and ask him to go to another tree.”
