Originally published in 1963, this volume is devoted to an analysis of the organisation of the Commissioners of Sewers, the Incorporated Guardians of the Poor, the Turnpike Trusts and the Improvement Commissioners, and depicts the important development of these bodies during the eighteenth century. By examining the constitutional features of these statutory authorities Mr. & Mrs. Webb support their main contention that here are to be found the beginnings of most of the Local Government services of the present day. But to most readers the chief interest of this volume will lie in the last two chapters, which analyse the whole development of English Local Government from the Revolution to the Municipal Corporations Act. This description of how the 'Old Principles' between 1689 and 1835 were gradually superseded by the 'New Principles' affords a convenient summary of the first four volumes.
