For fuller information on this topic see James Geikie’s “The Great Ice Age;” also, by the same author, “Prehistoric Europe.” In Appendix “B” of this latter work the author gives a map of Europe at the climax of the Glacial Age, showing the great extension of the glaciers. This map embodies the results of the labors of a great many eminent scholars. See also Croll’s “Climate and Time;” also Wallace’s “Island Life,” pp. 102-202. We are not aware that the statements as set forth above are seriously questioned by any geologist of note. Some consider it quite possible that the bowlder clays of Southern England and Central Germany were deposited during a period of submergence from melting icebergs. (Dawkins’s “Early Man in Britain,” p. 116.) But even this demands vast glaciers to the north of this supposed submergence to produce the icebergs. The weight of authority, however, is in favor of the glaciers. (Geikie’s “Prehistoric Europe,” p. 175.) Haywood’s Heer’s “Primeval World of Switzerland,” p. 200. “Prehistoric Europe,” p. 261. It is no longer a question that there was at least one mild period separating two periods of cold in Europe. See Lubbock’s “Prehistoric Times,” p. 316; Dawkins’s “Early Man in Britain,” pp. 115-120; Lyell’s “Antiquity of Man,” pp. 282-285., Dana’s “Manual of Geology,” first edition, p. 561; Haywood’s Heer’s “Primeval World of Switzerland,” Vol. II, p. 203; Wallace’s “Island Life,” p. 114; Croll’s “Climate and Time.” Mr. Geikie, in his works, “The Great Ice Age” and “Prehistoric Europe,” maintains there were several warm interglacial epochs.

Most geologists suppose there was a general depression of the region below the sea level, or so as to form inland lakes, and that the loess was thus deposited, as perhaps it is depositing at the present time in the lakes of Switzerland.
