(15) If a man throws some earth at his wife, both become thahu; this is a case for a medicine man, and both have to be purified. This only applies to those circumcised Kikuyu fashion.
(16) If food is eaten from a cracked pot the persons eating it become thahu and a mundu mugo has to be called in. This affects both sections of the tribe.
(17) The wives of smiths are usually decorated with armlets made of twisted strips of iron called mithiori. If a man enters the hut of a smith, and cohabits with a woman so decorated, he becomes thahu. A sheep has to be killed and a supply of honey beer provided; a strip of skin from the sheep is placed on the wrist of the [[110]]man, the woman, and any children she may have; this bracelet is placed on the left wrist of females, and the right wrist of a male. The purification ceremony is performed by another smith.
This thahu affects both sections of the tribe.
(18) Persons eating food in a smithy become thahu; the smith himself can purify one from this curse.
It affects both sections.
(19) If a bead worn on a warrior’s neck or waist falls into food, the persons who partake of the food become thahu; if such a bead falls into the grain store and becomes inadvertently cooked with the food the result is the same. This only affects persons circumcised Kikuyu fashion.
(20) If a Kikuyu has had his crops protected by magical processes performed by a medicine man (to protect in this way is called ku-roga), and someone takes food from a garden so protected, he becomes thahu, and this form of thahu can only be removed by the medicine man who has roga-ed the plantation.
This applies to both sections of the tribe.
(21) If a man has connection with a woman from behind, they are both thahu. This is a very serious thahu and both the athuri ya kiama and a mundu mugo are necessary to remove it, neither the man nor the woman being allowed to eat any of the sacrificial sheep.
