same laws of life, he was invested with an individuality which separated him from them. For a while the old influence of theological rule held even these venturous explorers to the ancient landmarks of human origin. By and by, the same impulse which had before led men to examine the proofs of physical creation induced them to consider the evidence of their own advent upon earth. Certain Scriptural statements did not appear reconcilable with each other. Cain went forth and builded a city; and there were artificers in brass and iron. Now Cain was only one of two men when he went forth. Whence came the citizens of that early settlement, and how did they understand the production of brass, a composite metal? How was it that man always met man wherever he went on the globe? Five thousand years ago the varied races were known to be distinct as now, and yet man was formerly said to be but about six thousand years old. Could one thousand years have produced the changes then evident, while five thousand succeeding years have scarce altered these different races? These and many other difficulties led thinkers to question whether man might not look much farther back into the past for his origin, and whether the same laws which had governed the birth, continuance, and distribution of other animals were not always in action to produce in him kindred results. The old belief, that all men descended from one man, began to be shaken; and good, honest, faithful Christians expressed their doubts of the matter. It was surmised that they were created in numbers. The old idea, that animals were all created in individual pairs, was found to be incompatible with the discovery of animal remains, in profusion, in rocks which were mud ages before any Adam could have existed to give them Hebrew names. Then, breaking away from the theological bonds, there sprang into active thought men of far-reaching minds, who began a thorough reconstruction of the whole theory of creation. The handwriting on the wall was Natural Law. All creation, man included, was but the result of one undeviating, unceasing, eternal, all-pervading law, and the state of the universe at any given moment was the state of evolution which that universe exhibited. Behind this law was the great inscrutable Spirit-power.
The infinite number of varied, aggregated facts stored up by man's patient study of this universe are irrelevant here, in a sketch of the progressive advance of his knowledge of creation. Those who desire to examine the evidence which has led to this verdict must go over the records themselves, or accept, out of their own convictions, the result of the examination. To entirely comprehend the Darwinian idea, one should be, to a certain extent, familiar with the principles of science. In other words, he should know more or less of what Darwin knows. He should be familiar with the general results of man's study in the different branches of science. He need not be an astronomer, a physicist, a geologist, a zoölogist, a botanist; but he should have a general acquaintance with the results of the labors of those who are such. He should, to a certain extent, understand the workings of Natural Law.
This is the great battle-ground on which the struggle is now taking place. The point at issue is, whether the physical changes of the material world, the introduction, continuance, and variation of organized beings, are due to the direct, special intervention of Deity, or whether they are the results of primeval laws, inherent in matter, and out of whose workings spring the phenomena of nature. The adherents to the former opinion maintain that the Deity has created all animals individually, or in individual species, by direct action, apart from natural forces, and indeed by an interference therewith. The votaries of the latter deny special creation, and maintain that all animals are, like the rest of the universe, the results of forces acting through all time, producing, by their diverse changing influ-
