No other great subject so invites the attention of the mind of man. It is a very long trail, rough and unblazed, wandering over the continents of the earth. Those who have travelled it came in contact with the mysteries of an unknown world. They faced the terrors of the shifting forms of the earth, of volcanoes, earthquakes, floods, storms, and ice fields. They witnessed the extinction of forests and animal groups, and the changing forms of lakes, rivers, and mountains, and, indeed, the boundaries of oceans.
