This probably casts light on many other so-called fetish collections of primitive people, as for example those of the North American Indians. “Mooney says, in describing the fetish, that it may be a bone, a feather, a carved or painted stick, a stone arrowhead, a curious fossil or concretion, a tuft of hair, a necklace of red berries, the stuffed skin of a lizard, the dried hand of an enemy, a small bag of pounded charcoal mixed with human blood—anything, in fact ... no matter how uncouth or unaccountable, provided it be easily portable and attachable. The fetish might be ... even a trophy taken from a slain enemy, or a bird, animal, or reptile.” (Hodge. HandbAmInd 1:458.) These fetishes might be kept in the medicine sack (the Chippewa pindikosan) or “It might be fastened to the scalp-lock as a pendant, attached to some part of the dress, hung from the bridle bit, concealed between the covers of a shield, or guarded in a special repository in the dwelling. Mothers sometimes tied the fetish to the child’s cradle.” (Hodge. HandbAmInd 1:458.) These fetishes represent not only events but ideas (a vision, a dream, a thought, or an action). They represent not only religious and mythological ideas and tribal records, but individual exploits in war or hunting and other individual records. In short, the medicine bag the world over is a collection of recorded ideas, both of historical and mythological character if not also of an economic character. So far as the “fetish” objects are not trophy objects, but stand for ideas, they form a transition to the mnemonic object, but so long as the object is such as to suggest to the keeper and expounder the idea of the particular form of words or ideas which he relates, it is still to be counted as object rather than mnemonic writing e.g. if a bit of fox fur suggests a story of a fox, it is still to be counted a pictorial object rather than a mnemonic object. If twenty eagle feathers, e.g. stand for twenty eagles, or twenty small bits of fur for twenty reindeer, these sample objects are still used pictorially, but if a feather head-dress is made of eagle’s feathers, each feather symbolizing some particular exploit, the matter has passed over from the pictorial to the mnemonic stage. § 14. _Mnemonic object libraries_ Mnemonic writing, as it is generally treated in the textbooks, includes all sorts of simple memory aids, and is generally, and probably rightly, regarded by writers of palaeography as preceding picture writing, although there is an element of abstractness even in the tally or knotted cord or pebble as compared with the actual imitation or representation of the picture, and in the evolution of human thinking, other things being equal, the abstract necessarily follows the concrete in time and in the order of evolution.
