In volume 8 of the Bulletin of the Society the writer described some of the characters of a boulder bed in the Gay Head cliffs and gave reasons for believing it to form the base of the Pleistocene deposits of the New England islands, at the same time pointing out its correlation with the Columbia of McGee.* In an earlier paper by Professor Shaler† a section was presented in which the geological position and distribution of this bed were indicated. The possible transportation of the fragments in this bed by some form of ice action was implied, but beyond the size of the boulders found in it, no direct evidence of glacial agencies had been discovered until April of this year. As the glacial origin of the deposit and its geological position have an important bearing on the extension of . . .
