In conclusion of this part of the subject, we may view the Drift period as the close of the great Tertiary era of geologists. In that era there was much dry land in the northern hemisphere, and multitudes of large animals now extinct inhabited it, apparently under a climate milder than at present. Great changes, however, took place in the relative positions of land and water, inducing very important changes of climate, which finally became of an almost Arctic char- acter over all the present temperate regions. The greater part of northern Europe and Asia appear to have subsided beneath the waters of the boulder-bearing semi-arctic ocean, until raised again by successive stages to be the abode of man and the animals of the modern earth. This final elevation, marked by the superficial gravels, appears to have fixed the present contour of the country, though the extinction of the mastodon and the phenomena of sub- merged forests show that important changes both in inorganic and organic nature have occurred subsequently, "We have thus, in tracing back the geological history of Acadia observed first, certain modern formations now in progress, and depending wholly on the present condition of the country. We have seen in connexion with these,.
