A delightful repose all this from the fierce personal controversies of a few years ago. Healthful truths are brought to light. On one and the same page, penetrate as deep as they may, all professions and their abettors join alike in admiration of the ineffaceable impress of the order, wisdom, and goodness everywhere to be traced in the structure of the globe. There is no longer the metaphysician vainly attempting to resolve the whole concrete mass into the ideal; or ridiculously striving to raise a structure of materialism, on the assumption that all our ideas, whatever we know and all we excogitate about, are derived through the medium of our sensations. The regions of infinite space are explored, and the devotional tendencies of the age have become the more decided and intense in proportion as the mental vision has been enlarged. The mind seizes with a firmer grasp, and advances with a steadier pace over the fields of creation, because there _is_ a Creator whose invisible Godhead is understood from the things which are made. And now, in search of truth, one and the same through all things, religion and science go hand in hand, sanctified and enlightened by the union, and imparting the most salutary lessons from the physical and moral revelations of Him whose path is in the deep places of the earth, and who for the display of his own glory has become the Instructor and Redeemer of the world. CHAPTER XI. THE LAMMERMUIRS—THE BORDER LAND—GENERAL STRUCTURE OF SCOTLAND. The interest which attaches to this division of our sketches of Scottish geology is in no degree impaired by the consideration that the rocks, all of them, belong to one or other of the systems which have already passed under review. A belt of undisputed Silurian deposit here meets us for the first time, flanked on all sides, and nearly throughout its length, by the old red sandstone. Porphyritic hills, greenstone bosses and dykes, and the various phenomena of trap intrusion and dislocation, are again presented in many and very striking illustrative details. “The border land,” physically as well as morally, could not well be without its points of contention; and, accordingly, geologists have made “raide across the marches,” and claimed as of Scottish origin an extensive domain of the English NEW RED sandstone, or Permian system. Corncockle Moor, too, and the quarries near Dumfries, unfold as curious a page in the history of the old world as does the Crigup Lynn, hewn out of the same family of rocks, of the stern warfare and fierce contendings which adorn, as they likewise disgrace, the annals of the seventeenth century.
