Abstract
GLACIALISTS making arrangements for their summer migration to Switzerland, and other geologists interested in ice-work, should read what Dr. A. R. Wallace has to say in the Fortnightly on “The Gorge of the Aar and its Teachings,” before they set out, and they will then be able to judge for themselves the weight of the conclusions drawn. Dr. Wallace thinks the phenomena presented by the valley of the Aar afford “a fresh and very powerful argument in support of the power of the ancient glaciers both to deepen valleys and to grind out lake-basins,” and his article is written to prove the correctness of this view. In the enclosed valley with its two small rock-basins in which the Hospice in the Grimsel Pass is situated, Dr. Wallace sees an example of the effects of a kind of eddy in old ice-streams flowing in nearly opposite directions.
