First article in a series by French textile authority Alfred Renouard, published during World War I, on rebuilding the textile industry of northern France (Department du Nord), most of which was then German-occupied. It argues that American makers of textile machinery will find opportunities replacing equipment destroyed or stripped, then surveys pre-war industry: Lille and flax/linen, Armentieres, Dunkirk jute and canvas, lawn and handkerchiefs at Chambray and Valenciennes, lace and tulle, and wool at Roubaix-Tourcoing. Includes three photographs of cotton spinning mills.
