To Agassiz, these parallel terraces explained themselves as the shores of a glacial lake, held back in its bed for a time by neighboring glaciers descending from more sheltered valleys. The terraces marked the successively lower levels at which the water stood, as these barriers yielded, and allowed its gradual escape. For details, see a paper by Agassiz on The Glacial Theory and its Recent Progress in the Edinburgh New Philosophical Journal, October, 1842, accompanied by a map of the Glen Roy region, and also an article entitled Parallel Roads of Glen Roy, in Scotland, in the second volume of Agassiz's Geological Sketches.

From that hypothesis you may proceed to fill the Baltic and the northern seas, cover southern England and half of Germany and Russia with similar icy sheets, on the surfaces of which all the northern boulders might have been shot off. So long as the greater number of the practical geologists
