stock language. A coalescence of tribes into a nation had not occurred in any case in any part of America.
A constant tendency to disintegration, which has proved such a hinderance to progress among savage and barbarous tribes, existed in the elements of the gentile organization. It was aggravated by a further tendency to divergence of speech, which was inseparable from their social state and the large areas of their occupation. An oral language, although remarkably persistent in its vocables, and still more persistent in its grammatical forms, is incapable of permanence. Separation of the people in area was followed in time by variation in speech; and this, in turn, led to separation in interests and ultimate independence. It was not the work of a brief period, but of centuries of time, aggregating finally into thousands of years; and the multiplication of the languages and dialects of the different families of North and South America probably required for their formation the time measured by three ethnical periods.
New tribes, as well as new gentes, were constantly forming by natural growth, and the process was sensibly accelerated by the great expanse of the American continent. The method was simple. In the first place there would occur a gradual outflow of people from some overstocked geographical center, which possessed superior advantages in the means of subsistence. Continued from year to year, a considerable population would thus be developed at a distance from the original seat of the tribe. In course of time the emigrants would become distinct in interests, strangers in feeling, and, last of all, divergent in speech. Separation and independence would follow, although their territories were contiguous. A new tribe was thus created. This is a concise statement of the manner in which the tribes of the American aborigines were formed, but the statement must be taken as general. Repeating itself from age to age in newly acquired as well as in old areas, it must be regarded as a natural as well as inevitable result of the gentile organization, united with the necessities of their condition. When increased numbers pressed upon the means of subsistence, the surplus removed to a new seat, where they established themselves with facility, because the government was perfect in every gens, and in any number of
