SWEDISH GEOLOGIST VISITS DARTMOUTH

At the meeting of the Dartmouth Scientific Association, Wednesday evening, May 3, Dr. Ernst Antevs of the University of Stockholm spoke on "A Measurement of the Recession of the North American Ice Sheet."

Doctor Antevs came to America in August. 1920, as a member of the Swedish Geological Expedition, with Baron Gerard DeGeer, under the auspices of the Scandinavian American Foundation. After the other members of the party had returned to Sweden, Doctor Antevs commenced a detailed study of the glacial clays of the Connecticut, Merrimac, Hudson, and Champlain valleys, applying methods originated by DeGeer. A year of field work and study of material collected has enabled Doctor Antevs to work out with a high degree of accuracy the length of time occupied by the melting away of the glacier in New England, from point to point, and to trace the fluctuations in climate during this period of several thousand years. His work affords the first exact chronology of the period when the ice sheet was receding, in North America, and when extended to Canada and the middle west may give a complete measure of the time since the last glaciation. It is regarded by those who have had opportunity to study his data as a study of wide significance.

In his work in New England and New York, Doctor Antevs has had the support of the National Research Council and the American Geographical Society of New York. Professor Goldthwait, who has been with him, from time to time, in the field, is cooperating with him in the preparation of his New England report, which will be published this summer as a memoir in the research series of the American Geographical Society. He will remain in Hanover the rest of this month.
