Hall’s Notes & Queries

These occasional comments are mostly additions to the book Water Transport in Brick, Stone and Concrete (Third Edition published in 2021), written with W D Hoff. Some are afterthoughts and clarifications, others new unpublished results.  There also some notes on other publications.
