The natives of British Columbia live largely upon the fish which abound in their seas and rivers. If the fish do not come in due season, and the Indians are hungry, A Nootka wizard will make an image of a swimming fish and put it into the water in the direction from which the fish generally appear. This ceremony, accompanied by a prayer to the fish to come, will cause them to arrive at once.

It is for the philosophic student to trace the train of thought which underlies the magicians practice; to draw out the few simple threads of which the tangled skein is composed; to disengage the abstract principles from their concrete applications; in short, to discern the spurious science from the bastard art.

If we analyze the principles of thought on which magic is based, they will probably be found to resolve themselves into two: first, that like produces like, or that an effect resembles its cause; and, second, that things which have once been in contact with each other continue to act on each other at a distance after the physical contact has been severed. The former principle may be called the Law of Similarity, the latter the Law of Contact or Contagion. From the first of these principles, namely the Law of Similarity, the magician infers that he can produce any effect he desires merely by imitating it: from the second he infers that whatever he does to a material object will affect equally the person with whom the object was once in contact, whether it formed part of his body or not.

If in the present work I have dwelt at some length on the worship of trees, it is not, I trust, because I exaggerate its importance in the history of religion, still less because I would deduce from it a whole system of mythology; it is simply because I could not ignore the subject in attempting to explain the significance of a priest who bore the title of King Of the Wood, and one of whose titles to office was the plucking of a bough — the Golden Bough — from a tree in the sacred grove.
