The ice age in North America and its bearing upon the antiquity of man5th edwith many new maps and illus., enland rewritten to incorporate the facts that bring it up to date, with chapters on Lake Agassiz and the Probable cause of glaciation . necessary to go into all the details concerningthe intricate network of kames which mark the lines ofdrainage over New England, when ice-barriers to so greatan extent directed the flow of the glacial torrents. The factsare impressive. Individual kames can be traced for long dis-tances, sometimes a hundred miles or more. The main linesin New England are shown on the accompanying map, be-ginning on the eastern side of Maine.* A few points merit particular attention. The Connecti-cut River Yalley, from its sources to the Massachusetts line,contains the remnants of what seems to be a pretty continu-ous kame, but which has been largely eroded, and in manycases covered up by subsequent deposits of river-silt.

For example,the Merrimack, between Lowell and its mouth, is crossed atright angles by two or three lines of kames, which descendinto the valley from one side and come out upon the hills onthe other.
