Part 1 of an International Textbook Co. instruction paper on mill engineering, covering the construction of textile mill buildings. It treats site selection (labor, markets, transportation, fuel, water supply), soils and foundations, footings, piles, foundation walls, mortar, brick and bricklaying, bonds, and measuring brickwork. It ends with slow-burning interior construction (floors, columns, roofs, monitors, fire-doors, windows) and a set of examination questions. It is illustrated with line drawings of footings, walls, bonds, piers, and a chimney; it is about building construction rather than weaving.
