When I wrote those chapters, and until this present month of January, 1884, I was doubtful whether I should not be regarded as fanciful or unreliable. I have now, however, just seen in _Good Words_ for this month, an article headed "Geology and the Deluge," from the pen of the Duke of Argyle, which appears to me conclusive on the points to which I allude, namely, first, that there was spread over the whole northern portion of this continent, a sea fifteen hundred feet above the land; secondly, that the depth of water was reduced to a thousand feet, and remained so during the formation of our Oak Ridges; and lastly, that a further subsidence of eight hundred feet took place, reducing the sea to the height of the Carlton beach; and that the latest of these subsidences must have occurred after our earth had been long peopled, and within historic times--probably at the date of the deluge recorded by Moses. His Grace says:-- "I think I could take any one, however unaccustomed he might be to geological observation or to geological reasoning, to a place within a few miles of Inverary, and point out a number of facts which would convince him that the whole of our mountains, the whole of Scotland, had been lying deeper in the sea than it does now to a depth of at least 2,000 feet. . . . I believe that the submergence of the land towards the close of what is called the Glacial Period, was to a considerable extent a sudden submergence, probably more sudden to the south of the country than it was here, and that the Deluge was closely connected with that submergence. . . . The enormous stretch of country which lies between Russia and Behring's Straits is very little known, and almost uninhabited. It is frozen to within a very few feet of the surface all the year round. In that frozen mud the Mammoth has been preserved untouched. There have been numerous carcases found with the flesh, the skin, the hair and the eyes complete. . . . Has this great catastrophe of the submergence of the land to the depth of at least two or three thousand feet, taken place since the birth of Man? In answer to this question I must refer to the fact now clearly ascertained, that Man co-existed with the Mammoth, and that stone implements are found in numbers in the very gravels and brick earths which contain the bones of those great mammalia."
