Three copies of a Letter, dated November 5, 1936, from Sister M. Monica to Sister Mary Gonzaga, relating to her the benefits of using scalebuoys in the water to the boilers and hot water systems.

Eleven page article titled Water Softening in the Boiler by the 'Alfloc' System. This is an internal method of conditioning boiler feed water and the use of coagulants designed to prevent scale formation in the boiler and accessory plant, to reduce corrosion to a minimum, and further to provide for those conditions in the boiler water which from present experience are believed to prevent the occurrence of caustic ombrittlement. Different chemicals were used to suit different types of water in different areas. Items discussed are: Summary, Introduction, External treatment, Internal Treatment, General Principles of the 'Alfloc' Internal Treatment, Precipitation of the Scale-forming Salts, Temporary Hardness, Permanent Hardness, Conditioning of the Precipitate - Floc Formation, Efficient Control of the Concentration of both Dissolved and Suspended Solids by Blowdown, Prevention of Corrosion, Testing and Control, The 'Alfloc' Reagents for Internal Treatment, 'Alfloc' Liquors, 'Alfloc' Briquettes, Alfloc' Powders, Methods of Application, Liquors - Stationary boilers and Locomotive boilers, Briquettes - Stationary boilers and Locomotive boilers, Powders, Blowdown, Sludge, Caustic Embrittlement, Control of 'Alfloc' System, Cost and Economies of 'Alfloc' Internal Treatment and 'Alfloc' Water Treatment Service. Listed on page 11 are ICIANZ Sales Offices the Australian States. Between pages 7 and 8 is a page of diagrams.
