After all, it may be regarded as still an open question, whether mankind is of one or many origins. The first human generation may have consisted of many pairs, though situated at one place, and these may have been considerably different from each other in external characters. And we are equally bound to admit, though this does not as yet seem to have occurred to any other speculator, that there may have been different lines and sources of origination, geographically apart, but which all resulted uniformly in the production of a being, one in species, although variously marked. It has of late years been a favourite notion with many, that the human race was at first in a highly civilized state, and that barbarism was a second condition. This idea probably took its origin in a wish to support certain interpretations of the Mosaic record, and it has never yet been propounded by any writer who seemed to have a due sense of the value of science in this class of investigations. The principal argument for it is, that we see many examples of nations falling away from civilization into barbarism, while in some regions of the earth, the history of which we do not clearly know, there are remains of works of art far superior to any which the present unenlightened inhabitants could have produced. It is to be readily admitted that such decadences are common; but do they necessarily prove that there has been anything like a regular and constant decline into the present state, from a state more generally refined? May not these be only instances of local failures and suppressions of the principle of civilization, where it had begun to take root amongst a people generally barbarous? It is, at least, as legitimate to draw this inference from the facts which are known. But it is also alleged that we know of no such thing as civilization being ever self-originated. It is always seen to be imparted from one people to another. Hence, of course, we must infer that civilization at the first could only have been of supernatural origin. This argument appears to be founded on false premises, for civilization does sometimes rise in a manner clearly independent amongst a horde of people generally barbarous. A striking instance is described in the laborious work of Mr. Catlin on the North-American tribes. Far placed among those which inhabit the vast region of the north-west, and quite beyond the reach of any influence from the whites, he found a small tribe living in a fortified village, where they cultivated the arts of manufacture, realized comforts and luxuries, and had attained to a remarkable refinement of manners, insomuch as to be generally called the polite and friendly Mandans. They were also more than usually elegant in their persons, and of every variety of complexion between that of their compatriots and a pure white. Up to the time of Mr. Catlin’s visit, these people had been able to
