Substitute materials. A shipment of 1,488 feet of 18-inch, 24-inch, 30-inch and 36-inch wooden pipe on one flat car. Weight 70,020 pounds. An equal footage of reinforced concrete pipe weighs 455,412 pounds, requires over ten cars. These pipes, used in place of corrugated iron or reinforced concrete pipes, are made of sections cut from short lengths of wood. Locking of adjacent rings with hardwood dowel pins produces a flexible structure. About 100,000 feet of these wooden pipes were installed in 1942 in drainage culverts, storm sewers and conduits, under highways and at army camps, naval stations, airfields and ordnance plants
