exchanged for skins and corn; wealth grows, and the habit of association--the first step toward civilization--arises. The little tribe is, however, compelled to occupy the higher lands. The lower ones are a mass of dense forests and dreary swamps, while at the foot of the hill runs a river, fordable but for a certain period of the year. On the hillside, distant a few miles, is another tribe; but communication between them is difficult, because, the river bottom being yet uncleared, roads cannot be made, and bridges are as yet unthought of. Population and wealth, however, continue to increase, and the lower lands come gradually into cultivation, yielding larger returns to labour, and enabling the tribe to obtain larger supplies of food with less exertion, and to spare labour to be employed for other purposes. Roads are made in the direction of the river bank. Population increases more rapidly because of the increased supplies of food and the increased power of preserving it, and wealth grows still more rapidly. The river bank at length is reached, and some of the best lands are now cleared. Population grows again, and a new element of wealth is seen in the form of a bridge; and now the two little communities are enabled to communicate more freely with each other. One rejoices in the possession of a wheelwright, while the other has a windmill. One wants carts, and the other has corn to grind. One has cloth to spare, while the other has more leather than is needed for its purpose. Exchanges increase, and the little town grows because of the increased amount of trade. Wealth grows still more rapidly, because of new modes of combining labour, by which that of all is rendered more productive. Roads are now made in the direction of other communities, and the work is performed rapidly, because the exertions of the two are now combined, and because the machinery used is more efficient. One after another disappear forests and swamps that have occupied the fertile lands, separating ten, twenty, fifty, or five hundred communities, which now are brought into connection with each other; and with each step labour becomes more and more productive, and is rewarded with better food, clothing, and shelter. Famine and disease disappear, life is prolonged, population is increased, and therewith the tendency to that combination of exertion among the individuals composing these communities, which is the distinguishing characteristic of civilization in all nations and in all periods of the world. With further increase of population and wealth, the desires of man, and his ability to gratify them, both increase. The nation, thus formed, has more corn than it needs; but it has no cotton, and its supply of wool is insufficient. The neighbouring nation has cotton and wool, and needs corn. They are still divided, however, by broad forests, deep swamps, and rapid rivers. Population increases, and the great forests and swamps disappear, giving place to rich farms,
