Page 88 - Every river appears to consist of a main trunk, fed from a variety of branches, each running in a valley proportioned to its size, and all of them together forming a system of valleys, communicating with one another, and having such a nice adjustment of their declivities, that none of them join the principal valley, either on too high or too low a level...
Page 88 - ... communicating with one another, and having such a nice adjustment of their declivities, that none of them join the principal valley, either on too high or too low a level; a circumstance which would be infinitely improbable, if each of these valleys were not the work of the stream that flows in it.
Page 154 - ... meridians, respectively. The extended axis of the earth intersects the celestial sphere at the celestial poles. Circles similar to the parallels of latitude on the earth are called parallels of declination, since the coordinate similar to latitude on the earth is called declination on the celestial sphere. As the earth rotates on its axis, from west to east, the celestial sphere appears to rotate in the opposite direction. Since the celestial meridians remain fixed over their corresponding meridians...

In this section preference is given to those features and processes which have directly helped or hindered man in his progress. In the second part of the book, on economic geography, the point of view is reversed, and the outlines of household management practiced by the great human family in its terrestrial home are presented against the background of the natural earth already...
Page 358 - The long, low coast line, with many drowned valleys, and the number of navigable waterways which penetrate the interior, render it easily accessible by water from the better half of the world. (2) Relief and Structure.
