There are spirits in the air, and in the ground, and inside trees, who make it their business to call human beings to their deaths. This is why, when a male child is born in many African tribes, he is not initially given his true name, but is lent a temporary fake appellation to confuse the spirits of death. Should the child survive his first few years — and most do not, despite this subterfuge — he is given his permanent name.
But even this is not his real name. That he selects for himself at puberty, and will probably never tell anyone. Thus the African travels under an alias at all times, secure in the knowledge that nobody knows who he really is.
However, the process of naming has two further ramifications. The African may privately rename those persons who are important in his life; this secret name, which he will not tell the person thus dubbed, gives him an important power over that person. And of course when traveling among people other than one's own tribe, one permits these strangers to cloak one with some nonsense syllable or other, to be shrugged off once the foreign travel is complete.
So Charlie's name was not Charlie. That was merely the bark he responded to when among the animals; that is, persons who were not Kikuyu. His death-fooling temporary name was long in the past, his permanent name was spoken exclusively by members of his branch of the Kikuyu in the villages along the western scarp of the Narandarua Range, and his real name was known only to himself.
Among the animals, the only one so far honored with a name By Charlie was Frank. Charlie had named him Mguu, and it gave him secret pleasure every time he saw the man to know that he alone knew this was Mguu. The name was from the Swahili — Mguu was not worth a name from Charlie's native Kikuyu dialect — and means "foot." It seemed to Charlie that foot expressed Mguu very well; his stamping around like an elephant, his roaring, his rushing into situations without thought or preparation. Also, Charlie had seen in the cinema cartoons about a blind white man named Mr. Magoo, and this seemed to add a proper dimension: Mguu, the blind foot.
