Excerpt from Familiar Lectures on Scientific SubjectsNow, to make this clear, I must go a little out of my way and say something about the first principles of geology. Geology does not pretend to go back to the creation of the world, or concern itself about its primitive state, but it does concern itself with the changes it sees going on in it now, and with the evi dence of a long series of such changes it can produce in the most unmistakable features of the structure of our rocks and soil, and the way in which they lie one on the other. As to wfzaz' we see going on. - We see every where, and along every coast-line, the sea warring against the land, and everywhere overcoming it wearing and eating it down, and battering it to pieces grinding those pieces to powder 5 carrying that powder away, and spreading it out over its own bottom, by the continued effect of the tides and currents. Look at our chalk clifi's, which once, no doubt, extended across the Chan~ nel to the similar cliffs on the French coast. What do we see? Precipices cut down to the sea-beach.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
