Recent Groundwater Investigations in the Netherlands [antikvár]

FOREWORD BY THE EDITORS The purpose of this Series on the Progress of Research in Holland during the war is to show the world that scientists in the Netherlands have remained active during the five years of German occupation. The publication of monographs by the most representative research workers was already planned in the first years of the war, as a token of the undaunted spirit of the Netherlands. In spite of the ever-growing burden of oppression and starvation research was continued intensively in all directions. Most of the material now published in this series was, for obvious reasons, kept a secret during the war. It being the Editors' aim to present these monographs as early as possible after the war, the majority of them were prepared whilst the war was still on. Authors were therefore expected to give mainly the results of their own investigations, without exhaustive reference to the Anglo-Saxon literature, which would not be available to them until after the war. The hope is expressed that the publication of this series will further intensify the interest shown by the allied nations in the fate of the Netherlands, demonstrating, as it does, the whole-hearted preparedness of our nation to contribute to the progress of mankind. The Editors wish to express their greatest admiration for the publishing house of Elsevier, which took very serious risk in preparing this series in wartime, when all activity on behalf of such international purposes was strictly forbidden. Amsterdam, on V.E.-day, 8th May 1945. The Editors, Dr Ir R. Houwink Dr j. a. a. Ketelaar
