Without pausing to analyse the complex character assigned to the Neck, it will be abundantly clear that he belongs to the same category as the foregoing, and may be subdued by similar means. To fetch parallels to the spirit of the Jabbok from Scotland and Sweden may be thought going far afield. It is going no farther than Dr Frazer himself goes for examples of the custom of propitiating river-spirits. The protest often uttered by cautious anthropologists against those who would cast the net so widely has its reason. When we are dealing with customs it is well to remember that customs superficially alike may spring from quite different social organizations, and their real intentions may be divergent or even opposite: in short, they may have nothing in common but external resemblance. They cannot be understood without taking into account the sequences of which they are often part, and the social organization and cultural condition from which they spring. It is otherwise when those great products of human imagination that animate the world about us are concerned. The personalities believed to haunt mountain and stream, air and water, heaven and earth, are elemental conceptions, the inevitable offspring of the human mind in its intercourse with nature. Analogies discovered between them are real analogies; they are the proofs of the essential oneness of mankind in the snow-hut of an arctic winter and the tree-shelter of a tropical forest. And when we find the relations believed to exist between such personalities {167} and human beings, the need of their conciliation or coercion in order to obtain benefits for their human worshipper or antagonist, and the means taken for this purpose, the same, with only such variations as may be accounted for by differences of environment, then we may with confidence appeal to them as mutually illustrative.
