    This paper presents a history of the pore-pressure measuring apparatus developed and used by the U. S. Bureau of Reclamation. The installation of test apparatus involves many innovations that have been developed over the years, and the methods for such installation continue to be improved with each project. Since the basic details of the methods for installation of the various types of earth dam tests apparatus are reported elsewhere, the emphasis in this presentation is on the development of the piezometer apparatus.
