I am also under a debt of gratitude to Professor Tylor. He also is not involved in my opinions, but he kindly ermits me to tell him things that I can only "tell Tylor"; and now and again, as you will see in the Fetish question, he comes down on me with a refreshing firmness; in fact, I feel that any attempt at fantastic explanations of West African culture will not receive any encouragement from him; and it is a great comfort to a mere drudge like myself to know there is some one who cares for facts, without theories draping them. I will merely add that to all my own West Coast friends I remain indebted; and that if you ever come across any one who says I owe them much, you may take it as a rule that I do, though in all my written stuff I have most carefully ticketed its source. I now turn to the explanation and apology for this book, briefly.
