AFFECTED BY ICE DEPOSITS

Seeming Proof That Crust of the Earth Has Had Periods of Rising and Falling. The elastic character of the earth’s crust is one of thfe most certain facts of observation; great areas rise and fall under the action of varying pressures. It is, therefore-, reasonable to suppose that the accumulation in pleistocene times of vast continental glaciers one or two miles In depth would exert such downward weight pressure as to cause a subsidence of the great areas affected. This seems to be borne out by a marked and very apparent rise of land in the northeastern section of the North American continent, in comparatively recent times. H. L. Fairchild, writing in Science, states that this area, covered by the latest American ice sheet, the Labradorian glacier, stood much below its present position, relative to sea level, when the ice sheet melted off, and that a slow uplift brought the land to its present altitude. This is indicated by the presence of the rctnafns of sea animals and plants throughout inland parts, by beach formations In parts now away from the sea and general geological considerations. The region of this recent rise of land extends from New Jersey to Hudson strait and as far inland as Wisconsin.
