JOHNSTON'S PHYSICAL GEOGRAPHY.[7]
In this age of scientific illustration, no more splendid work has been produced than the one of which we now give some general notice to our readers. It is not our purpose to panegyrise either the work or the author; but it is only justice to say, that no work more distinguished by completeness of knowledge on its subject—by the novelty, variety, and depth of its researches—by the skill of its arrangement, and by the beauty of its engravings and typography—has ever appeared in this country, or in any other. It is a magnificent tribute to the science and to the skill of England.
The author, in his desire to acknowledge his obligations, by stating that his work is founded on the Physical Atlas of Professor Berghaus, has done himself injustice. His volume, though naturally availing itself of all contemporary knowledge, exhibits all the originality which can make it his own.
Of all modern sciences, the science of the globe has made the most rapid, the most remarkable, and the most important progress. Bacon makes the fine remark, that while the works of man advance by successive additions, the works of Nature all go on at once: thus the machinist adds wheel to wheel, and spring to spring, but the earth produces the tree, branch and bark, trunk and leaf, together. There is something analogous to this combined operation in physical geography: a whole crowd of remarkable discoveries seem to have burst on us at once, expressly designed to invigorate and impel our progress in geographical science. Thus, our century has witnessed new phenomena of magnetism, new laws of heat and refrigeration, new laws even of the tempest, new rules of the tides, new expedients for the preservation of health at sea, new arrangements for the supply of fresh food, and even for the supply of fresh water by distillation, and all tending to the same object—the knowledge of the globe.
The use of steam, to which modern mechanism has given almost a new existence, and certainly a new power—the conquest of wind and wave by the steam-ship, and the almost miraculous saving of time and space by the steam-carriage; the new necessity of remote enterprise, originating in the urgency of commercial and manufacturing difficulties; the opening of the thousand islands of the Indian Archipelago, till now known to us as scarcely more than the seat of savage life, or the scene of Oriental fable; the breaking down of that old and colossal barrier of restrictions and prejudices, which, more than the wall of China, excluded England from intercourse with a population amounting to a third of mankind; and most of all, those vast visitations of apparent evil, which the great Disposer of things is evidently transmuting, year by year, into real good, by propelling the impoverished multitudes of Europe into the wildernesses of the world—all exhibiting a stupendous combination of simple means, and a not less astonishing convergency to the one high purpose, the mastery of the globe—place Physical Geography at the head of the sciences essential to the happiness and power of humankind.
In the glance which we shall give at this great science, we look only to the external structure of the earth; briefly protesting against all those theories which refer its origin to an earlier period, or a longer process, than the "six days" of Scripture. It is true, that Moses may not have been a philosopher, though the man "learned in all the wisdom of the Egyptians" may have known more than many a philosopher of later days. It is equally true, that the object of the Book of Genesis was not to give a treatise on geology. But Moses was a historian—it is the express office of a historian to state facts; and if Moses stated the "heavens and the earth, and all that therein is," to have been created and furnished in "six days," we must either receive the statement as true, or give up the historian as a fabricator. But if we believe, in compliance with the Divine word, that "all Scripture is by inspiration of God," by what subterfuge can we escape the conclusion, that the narrative of Genesis is divine? Or if, in the childish scepticism of the German school, we require a more positive testimony, what can be more positive than the declaration of the commandment of the Sabbath, "that in six days God made heaven and earth;" founding also upon this declaration the Sabbath—an institution meant for every age, and for the veneration and sanctification of every race of mankind? If such a declaration can be false, what can be true? If ever words were plain, those are the words of plainness. The law of Sinai was delivered with all the solemnities of a law forming the foundation of every future law of earth. It would have been as majestic, and as miraculous, to have fixed the creation at a million of years before the being of Adam. But we can discover no possible reason for the history, but that it was the truth. That truth is divine.
If the geologist shall persist in repeating, that the phenomena are incompatible with the history, our reply is, "Your science is still in its infancy—a science of a day, feebly beginning to collect facts, and still so weak as to enjoy the indulgence of extravagant conclusions. There have been a thousand theories of creation—each popular, arrogant, and self-satisfied, in its own time; each swept away by another equally popular, arrogant, and self-satisfied, and all equally deserving of rejection by posterity. You must acquire all the facts, before you can be qualified to theorise. The last and most consummate work of genius, and of centuries, is a true theory."
But, without dwelling further on this high subject, we must observe, that there is one inevitable fact, for which the modern geologist makes no provision whatever; and that fact is, that the beginning of things on the globe must have been totally different from the processes going on before our eyes. For instance, Adam must have been created in the full possession of manhood; for, if he had been formed an infant, he must have perished through mere helplessness. When God looked on this world, and pronounced all to be "very good"—which implies the completion of his purpose, and the perfection of his work—is it possible to conceive, that he looked only on the germs of production, on plains covered with eggs, or seas filled with spawn, or forests still buried in the capsules of seeds; on a creation utterly shapeless, lifeless, and silent, instead of the myriads of delighted existence, all enjoying the first sense of being?
But, if the first formation of the world of life must have been the act of a vast principle, to which we have no resemblance in the subsequent increase and continuance of being, what ground have we for arguing, that the common processes of material existence in our day must have been the same in the origin of things? On the whole, we regard the declaration—"In six days God made the heavens, and the earth, the sea, and all that in them is," as an insuperable bar to all the modern fantasies of the geologist, as a direct rebuke to his profaneness, and as a solemn judgment against his presumption.
The whole surface of the globe gives striking evidence of design, and of design contemplating the service of man. But one of the most remarkable evidences of that design is given in the Mountain Map of the globe. Variety of temperature, the supply of water, and the change of level, are essential to variety of production, to fertility of soil, and to the vigour and health of the human frame—the expedient to meet them all is provided in the mountain districts of the great continents. A mountain chain girdles the whole of the mass of land from the Atlantic to the Sea of Kamchatka. Minor chains, some parallel, some branching from the great northern chain, and some branches of those branches, intersect every region of the globe. The whole bears a remarkable resemblance to the position of the spine in the human frame, with its collateral muscular and venous connexion with the body. An outline view of the mountains of our hemisphere would be strikingly like a sketch of the human anatomy. The general formation of the countries north and south of those chains is early the same—vast plains, extending to the sea, or traversed and closed in by a bordering chain. The great Tartarian desert is a plain extending, under various names, five thousand miles from west to east.
