The day before the sacrifice, the women of the neighbourhood gather together and go to the sugar cane plantations, every woman bringing back two or three sticks of cane and taking them to the thomi, or village meeting place, of one of the elders, where they are crushed to make beer. In the evening, the elders of ithembo take the beer and place it near the sacred tree. They light a fire there with a firebrand from the village, and the gourds of beer are put near it; a little beer is also poured at the foot of the tree and they pray to the imu of the person to whom the tree is dedicated, and then return home. It is believed that the object of this ritual is to attract the attention of [[57]]the guardian spirit of the shrine, and to propitiate it and to ensure, as it were, its attendance on the morrow as the intermediary between the people and Engai.

In the morning, the elders of ithembo and certain very old women proceed to the ithembo. The elders bring the sacrificial beast and first suffocate it; they then quickly skin its throat, and the oldest of the elders stabs it in the neck with a knife, collecting the blood in a half gourd (nzeli). The skinning is then completed, and small pieces of meat are cut from the tongue, ribs, and the left flank. One kidney, one testicle, and a piece of the liver, heart, and every internal organ are also taken, all these fragments being placed in a half gourd. They then take a half gourd of beer, and the gourds containing the meat and the blood, and empty them at the foot of the tree. The old women now approach and deposit samples of every kind of field produce—beans, maize, and so forth—and milk. Some of the food is cooked and some is raw.

When the men deposit their offerings they pray as follows: “Engai twaevoya mbua kuamba eyima sionthi Engai”—“We pray to God that rain may bless all our country.”

The women merely say “Twaevoya mbua”—“We pray for rain.”

The sacrificial meat is then cooked and eaten. The first to partake of it are the four senior elders.

The fire for cooking the meat is lit a little away from the tree, and the fuel must consist of dry sticks picked up in the sacred grove. The fire having been lit, a small staging is built over it, and the pieces of meat are placed thereon to roast. The place of the fire is called ivuvio; the wood used for the framework is muthakwa; the sticks composing it are mbatwa, and the whole framework when completed is called ndala.

When removing the marrow the bones of the sacrificial animal must not be broken.

After the feast the bones are collected and placed [[58]]on the fire and covered with the stomach contents (tatha or muyo), and the smoke which rises to heaven is said to be pleasing to Engai.

A private sacrifice is called kithangaona by the Kamba people, its object being to purify a village from sickness. The ceremony is also termed kuvindukia muimu—“to cleanse the place from the spirit” (ku-indukia—to cleanse) and may possibly have an implied meaning to the effect that the spirit must be appeased.

Sometimes a woman who goes into a cataleptic condition, which is known as being seized by aiimu, will say that to obtain rain a beast of a particular colour must be sacrificed. A black goat is said to be preferable as a supplication for rain, the colour probably being symbolical of the rain clouds.
