Did you ever notice, on your map of Europe, how the curve of the Carpathian Mountains follows the curve of the shore of the beautiful Adriatic Sea so far away?[23] What does that remind you of in the story of the relation between the mountains and the sea? [Footnote 23: How far away is it? The scale of miles on your map will tell.] "Yes," you say, "but if mountains are formed on the borders of the sea why are the Carpathians so far from the Adriatic; and the Alps so far from the Mediterranean and the Rocky Mountains of America and the Altai mountains of Asia so far away from any sea at all?" Professor Heilprin[24] knew you would say that; at least I suppose he did, for he has explained all this in his little book, written especially for young people, "The Earth and Its Story." After you have read this part of the story write it out in your own words and then copy it into your notebook. You might call your own story, "How Mountains are Moved Back from the Sea." [Footnote 24: Professor of Geology in the Academy of Natural Sciences, Philadelphia.] What mountains do the waves of the Indian Ocean rise to salute? How do they compare in size with other mountains that you know of? How does the carbon in the gases of volcanoes get into the plants? What does it say in Proverbs 6:6 that might remind one of the fact that the ants helped solve the puzzle as to how volcanoes are made? As to the hills that were moved in, a Wisconsin writer, who has, among other things, written delightfully of his companionship with the rocks and hills of his State[25] tells about sinking a well 132 feet deep on his farm, and going through this imported scenery all the way. [Footnote 25: Charles D Stewart, "Essays on the Spot."] "Somewhere down there," he says, "if I had kept on going I should have struck the original Wisconsin." And why not be an author yourself? Start a little book of science of your own and learn to make notes on interesting things you have been reading about. For instance, put in it now some of the different things we have learned about the wonder-workers of the Ice Age, up to and including this chapter. Call what you write "The Story of the Old Men of the Mountain." At the end of the part you write now you can put "To be continued," just as they do in a story paper; for we are not through with the work of the old men, as you will see. How did Rome get its seven hills? (You know it was called The City of the Seven Hills.) The Bible quotation in Ruskin about the trembling of the mountains is from Jeremiah 4:24. How grand it sounds, doesn't it? Like the music of a pipe organ. The Bible has many references to "hills" and mountains. Here are some of the most striking: Psalms 114:4; Exodus 20:18; Deut. 5:23; Rev. 8:8; Micah 1:4; Isaiah 54:10.
