In 1858 James Thompson filled this blank book with notes about the plumbing and water system in the Flass House in Cumbria County, England, which was being constructed circa 1848-1861 by Lancelot and Wilkinson Dent. Thompson wrote about pipes, taps, cisterns and reservoirs, boilers, drains, hard and soft water, hot and cold water, and more. It indicates the use of plumbing, the location of pipes and how they connected to other plumbing equipment, and types of water access in interior spaces including sculleries, bathrooms, water closets, washstands, and butler's pantries. Thompson also noted pipes feeding exterior water supplies like for the cattle's trough, the conservatory, and fountain. Thompson included several pen-and-ink sketches of floorplans and maps of the property to illustrate the location of pipes, as well as a pencil sketch of the house's façade.
The volume has a green printed cover with an image of a man and woman standing beside each other in an interior space, labelled "The Squire and his Servant." Various "Arithmetical Tables" are printed on the back cover, including a multiplication table and various conversion tables.
