There is one particular to which I wish to call your attention. The ocean seems to have been gathered by itself, when the dry land appeared, and whether or not there were any islands at that period of our globe's history, we are not informed. You might inquire—What has occasioned two great continents and two great oceans intervening between them, and how are we to account for the appearance of islands and seas as they now exist? These are the results of other changes since the days of the organization of this earth, as proclaimed by Moses. The flood, no doubt, produced some changes on the surface of our globe, but still I do not believe, for a moment, that it could have produced the changes we now see. So far as the location of the different islands and continents is concerned, we descend to a period since the flood. In the days of Peleg, we are told, the earth was divided. This is a very short historical notice of a very marvelous event. If we had the whole account of this occurrence precisely as it transpired, it would certainly be extremely wonderful. Supposing that the one great antediluvian continent, which must have existed prior to that time, were to be divided by several thousand miles of water, would not that be a most wonderful event?
