_Change from Savagery to Barbarism_.--Perhaps one of the broadest classifications of ancient society, based upon general characteristics of progress, makes the two general divisions of {49} savagery and barbarism, and subdivides each of these into three groups. The lowest status of savagery represents man as little above the brute creation, subsisting upon roots and berries, and with no knowledge of art or of social order. The second period, called the middle status of savagery, represents man using fire, and using fish for food, and having corresponding advancement in other ways. The upper status of savagery begins with the use of the bow-and-arrow and extends to the period of the manufacture and use of pottery. At this point the period of barbarism begins. Its lower status, beginning with the manufacture of pottery, extends to the time of the domestication of animals. The middle status includes not only the domestication of animals in the East but the practice of irrigation in the West and the building of walls from stone and adobe brick. The upper status is marked by the use of iron and extends to the introduction of the phonetic alphabet and literary composition. At this juncture civilization is said to dawn. "Commencing," says Mr. Morgan, the author of this classification, in his _Ancient Society_, "with the Australians and the Polynesians, following with the American Indian tribes, and concluding with the Roman and Grecian, which afford the best exemplification of the six great stages of human progress, the sum of their united experiences may be supposed to fairly represent that of the human family from the middle status of savagery to the end of the ancient civilization." By this classification the Australians would be placed in the middle status of savagery, and the early Greeks and Romans in the upper status of barbarism, while the Pueblo Indians of New Mexico would be placed in the middle status of barbarism. This is an excellent system for estimating the progress of ancient society, for around these initial periods may be clustered all of the elements of civilization. It is of especial value in the comparative study of different races and tribes.
