This first encyclopedia of its kind consists of 450 articles varying in length from Aar, the longest river in Switzerland to Zurich, the lake which is dominated by this country's leading city. In the rear, there is a Gazetteer with an additional three or four line listing of some 2000 other bodies of water. There are 100 illustrations, 16 in full color which leave something to be desired. Index. A companion volume to Mountains and Oceans and Islands, also in this series.
