of the cold, there would be little motion northerly. (4) TheLabrador peninsula seems to me to offer a good situation for the accum-ulation of an ice-cap large enough to account for all the phenomena. Thefiords on the east indicate north-east movements of the ice; and threeother courses have been mentioned, so that we find good evidence ofmotion in four directions from the central table land. Supposing this acentre, Greenland would have been a second, of equal or greater height,and the two would discharge their surplusage into the Atlantic. A capof thirteen miles would be required for the thickness of this ice, if therewere a flow from it to the western edges of the plains. (5) The growthof Greenland and the neighboring parts of the continent suggests theorigin of the great basins, as of Baffins bay, in Eozoic times, and a prob-able submergence ever since. The Hudsons Bay depression is similar(see Fig. i, Vol. H). The Miocene deposits of Baffins bay were made no ICO ISO 1*0 ly aa o °

There was rather moresubsidence, showing that the tendency in modern times has been toenlarge rather than restrict the size of the bay. (6) The coldest part of the continent lies to the west and north ofHudsons bay. A comparison of meteorological tables given in variousarctic expeditions indicates a greater average degree of cold in the west—say at Fort Reliance in Ruperts Land—than very far north. No greaterdegree of cold has been observed, but a lower average is reported forGreenland. For example: the lowest temperature indicated during thewhole of one winter on the Hansa, which drifted along the entire eastcoast, was only —11° F. On the contrary, t
