We have also shown that the earth still obeys the divine command to bring forth, or--if objection be made to this form of statement as unscientific--still obeys some inexorable underlying law tantamount to such command, and can no more help "bringing forth," when the necessary telluric conditions favor, than the cold can help coming out of the north, or the clouds dropping rain, when the necessary meteorological conditions occur. Give the future American botanist the physical geography of a country--its average rain-fall, temperature, etc., and the plant zone in which it lies, and, whether explored or unexplored, he will give us the general character of its vegetation, and name most of the plants and trees peculiar to its soil. And he will do this, not because he has any faith in the present theories of plant-migration, nor in the necessary distribution of seeds, but because he will study his favorite science with reference to latitude, elevation, climate, physical characteristics, rain-fall, soil-constituents, and other influencing conditions of plant-life. But we will now proceed to consider the duration of vegetable species, for the purpose of showing that the evolutional changes they are undergoing, if any, must cover infinitely vaster periods of time than we have any data for determining, to say nothing of the unverified theories the evolutionists have been spinning for us. Our geologic and paleontologic records are becoming richer in materials, more interesting in details, and more authentic in character, every year. We are turning back page after page of these lithographic records, only to find the domain of science widened and deepened in interest as we advance, or as our rocks are being excavated, our mountains tunneled, our vast mines explored, and the beds of our rivers and arms of seas thoroughfared and traversed by the iron rail. Meanwhile, science exhibits signs of becoming less devoted to new-fangled theories, more exacting in her demands upon her votaries, and more eager to extend the domain of facts as the only true basis on which to rest her claims for future recognition. She is less dogmatic to-day than she was a year ago, and is likely to become less so a year hence than now. And this is largely due to her methods of research and inquiry. She is now everywhere sending out her hardier and more enthusiastic sons into new fields of exploration, to return laden with ampler materials to build, and richer treasures to adorn, a temple worthy of her name. In the field of the fossilized fauna and flora, these treasures are of the highest value and interest, all indicating not only wide areas of distribution, but immense periods of time, in which species have existed without any greater changes in character than the necessary shadings into varieties would seem to require. For nature everywhere characterizes her methods of production and reproduction by a loving tendency to diversify and variously adorn
