Acknowledgements
My sincere thanks are due in the first instance to Mrs. A. Heineke-Sieuwerts for the many hours she spent deciphering my untidy hand in the preparation of the type-written manuscripts. Also the secretary of the Department of Germanic Studies, Mrs. M. Nogeste, is to be thanked for the assistance she lent in successful completion of the manuscript. But this book would certainly never have seen the light of day had my employer, the University of Melbourne, not granted me sabbatical leave in 1980-81 and thus relieved me of teaching and administrative duties. The university also made generous sums of money available from time to time for typing and the drawing of the maps, the work of Mr. R. Bartlett of the Geography Department of the University of Melbourne. I am also indebted to Mr. R. Martens for the compilation of the index and to Dr. M. Klein from the Catholic University of Nijmegen for his careful reading of the manuscript and the valuable suggestions he made.
Finally a word of thanks to the Instituut voor Oudgermaanse, Skandinavische en Friese Taal- en Letterkunde at the State University of Utrecht for making a room and library facilities available to me during the period of the said study leave.
