A year-by-year history of the machine-made tulle and lace industry in the Pas-de-Calais (Calais and Saint-Pierre-les-Calais, with sections on Arras), from 1815 to 1900, written by a Calais manufacturer. It covers the introduction of the bobbinet, Leavers and Jacquard machines, statistics on looms and output, patents, exhibitions and awards, customs and trade policy, labour relations, unions and strikes, and market conditions. A technical section near the end describes how lace is produced on the machines. Many pages carry photographs of machine-made lace samples, with captions naming the manufacturer and year.
