Man, like the other creatures, was destined to be fruitful and multiply and replenish the earth. We are also informed in chapter second that he was placed in a "garden," a chosen spot in the alluvial plains of Western Asia, belonging to the later geological formations, and thus prepared by the whole series of prior geological changes, replenished with all things useful to him, and containing nothing hurtful, at least in so far as the animal creation was concerned. These facts, taken in connection, lead to grave questions. How is the happy and innocent state of man consistent with the contemporaneous existence of carnivorous and predaceous animals, which, as both Scripture and geology state, were created in abundance in the sixth day? How, when confined to a limited region, could he increase and multiply and replenish the earth? These questions, which have caused no little perplexity, are easily solved when brought into the light of our modern knowledge of nature. 1. Every large region of the earth is inhabited by a group of animals differing in the proportions of identical species, and in the presence of distinct species, from the groups inhabiting other districts. There is also sufficient reason to conclude that all animals and plants have spread from certain local centres of creation, in which certain groups of species have been produced and allowed to extend themselves, until they met and became intermingled with species extending from other centres. Now the district of Asia, in the vicinity of the Euphrates and Tigris, to which the Scripture assigns the origin of the human race, is the centre to which we can with the greatest probability trace several of the species of animals and plants most useful to man, and it lies near the confines of warmer and colder regions of distribution in the Old World, and also near the boundary of the Asiatic and European regions. At the period under consideration it may have been peopled with a group of animals specially suited to association with the progenitors of mankind. 2. To remove all zoological difficulties from the position of primeval man in his state of innocence, we have but to suppose, in accordance with all the probabilities of the case, that man was created along with a group of creatures adapted to contribute to his happiness, and having no tendency to injure or annoy; and that it is the formation of these creatures--the group of his own centre of creation--that is especially noticed in Genesis ii., 19, _et seq._, where God is represented as forming them out of the ground and exhibiting them to Adam; a passage otherwise superfluous, and indeed tending to confuse the meaning of the document. 3. The difficulty attending the early extension of the human race is at once obviated by the geological doctrine of the extinction of species. We know that in past geological periods large and important groups of species have become extinct, and have been replaced by new groups extending from
