Excerpt from book: other and different subdivisions necessary. Stone implements were not entirely laid aside with the introduction of tools of iron, nor of those of bronze. The invention of the process of smelting iron ore created an ethnical epoch, yet we could scarcely date another from the production of bronze. Moreover, since the period of stone implements overlaps those of bronze and of iron, and since that of bronze also overlaps that of iron, they are not capable of a circumscription that would leave each independent and distinct. It is probable that the successive arts of subsistence which arose at long intervals will ultimately, from the great influence they must have exercised upon the condition of mankind, afford the most satisfactory bases for these divisions. But investigation has not been carried far enough in this direction to yield the necessary information. With our present knowledge the main result can be attained by selecting such other inventions or discoveries as will afford sufficient tests of progress to characterize the commencement of successive ethnical periods. Even though accepted as provisional, these periods will be found convenient and useful. Each of those about to be proposed will be found to cover a distinct culture, and to represent a particular mode of life. The period of savagery, of the early part of which very little is known, may be divided, provisionally, into three sub- periods. These may be named respectively the Older, the Middle, and the Later period of savagery; and the condition of society in each, respectively, may be distinguished as the Lower, the Middle, and the Upper Status of savagery. In like manner, the period of barbarism divides naturally into three sub-periods, which will be called, respectively, the Older, the Middle, and the Later ...
