She repeated her visits until the natives insulted her, whereupon she went underground with her fire-made treasures and came back no more. Whatever may have been the circumstances that led the earliest families to cross from Asia to America, they little recked that they had found a new continent and that they were the first of the red race.
That is to say, it was supposed that fire-action had come first and water-action second; that the fire-made rocks were all formed in very early ages, and that only water-made rocks still continued to be formed.
The Fire-made Rocks, both Plutonic and Volcanic; The Water-and-Fire-made Rocks. The first of these Water-made Rocks may be subdivided into three classes. These are, I. Flint Rocks; II. Clay Rocks; III. Lime Rocks. This is not a book in which it would be wise to go closely into the mineral nature of rocks. Two or three leading thoughts may, however, be given.
In all ages of the world's history up to the present day, rock-making has taken place fire-made rocks being fashioned underground, and water-made rocks being fashioned above ground though under water. Also in all ages different kinds of rocks have been fashioned side by side limestone in one part of the world, sandstone in another, chalk in another, clay in another, and so on.
We see therefore clearly that, although the earliest fire-made rocks may very likely date farther back than the earliest water-made rocks, yet the making of the two kinds has gone on side by side, one below and the other above ground, through all ages up to the present moment.
We see this at once; but they become much more interesting when we know that each has its own history. The granite is one of the fire-made rocks, so called because there are marks upon it, like letters written long ago, quite plain to those who have the skill to read them; which show that though it is now so hard, it was once soft, as soft as iron becomes when melted by very great heat.
