✦ Synopsis

This volume of selected papers by Professor A W Skempton is published to mark his 70th birthday on 4th June 1984.In making the selection of papers we aimed to show Skempton's breadth of interest and achievement int he general field of mechanics and to include papers that the practising engineer, research worker and student will find of value to have at hand. For the early papers the selection was influenced by a historical interest in addition to intrinsic merit.
