Turning to the lower races of mankind that now survive and are accessible to study, we find only very few scattered, fragmentary, and often contradictory data as to old age. Yarrow has made a comprehensive study of mortuary customs, both of savages and man in the earlier stages of civilization. Mallory brought together what we know of sign language. Ploss has given us a compend on the child among primitives and, with Bartels, on woman. I have tried to compile the customs and ideas of pubescent initiation;[33] while animism, marriage rites, property and ownership, systems of kinship, mana concepts, hunting and trapping, war weapons, dances, ideas of disease and the function of the “medicine man,” dwellings, dress, ornamentation, number systems, language, fire-making, industries, food, myths, and ceremonies galore, and many other themes have had comprehensive and comparative treatment. But I am able to find nothing of the kind (and Professor F. Boas, our most accomplished American scholar in this field, knows of nothing compendious) on old age in any language. Anthropology, therefore, has so far produced no gerontologists. I have looked over many volumes of travel and exploration among the so-called lower races of mankind, only to find nothing or brief and more or less incidental mentions of senescence. This neglect is itself significant of the inconspicuous rôle the old play in rude tribal life and also of the lack of vital interest in the theme by investigators. From my own meager and inadequate gleanings in this field the unfavorable far outweigh the favorable mentions. The Encyclopedia Britannica tells us that from Herodotus, Strabo, and others we learn of people like the Scythian Massagetæ, a nomad race northeast of the Caspian Sea, who killed old people and ate them. For savages the practice of devouring dead kinsfolk is often regarded as the most respectful method of disposing of their remains. In a few cases this custom is combined with that of killing both the old and sick, but it is more often simply a form of burial. It prevails in many parts of Australia, Melanesia, Africa, South America, and elsewhere.
