Numerous people have helped in preparing these two volumes and I should like to thank them for their very kind and generous assistance. In particular Pat Jenkins, John Leftwich, Janet Mason, and Julie Sharp, of the Royal Military College of Science, Cranfield University, who prepared and corrected the large number of drawings and figures from my own rather inadequate sketches. The Librarystaff at the Royal Military College of Science obtained and traced numerous obscure references, papers, and books. Keld Fenwick and Tony Woolrich made many helpful suggestions, and the latter supplied much information relating to textiles. Dick Swann, of the Newcomen Society, was a helpful guide to their records. Geoffrey Eastwood, Patrick Wormell, and my wife Barbara Lawton, read and corrected the manuscript and saved me from potentially embarrassing errors. Geoffrey Eastwood also prepared the subject index and the name index, for which I am particularly grateful. Finally I must thank my wife, again, for her patient and time-consuming work in tracking down copyright holders and obtaining permissions for the many figures. The remaining errors and lapses are, of course, my responsibility.
Every effort has been made to trace the copyright owners for the images I have used but it has not always been possible. The owners of copyright to images that may have been reproduced without their permission are invited to contact the publishers who will correct the omissions in any future editions.
