This is so near the welding point that aperfect union results and the rail is made the average joint for a 4^-inch rail no pounds of metalare used. It is cast in a long, oval-shaped slug extendingfor nearly a foot on each side of the joint, Fig. 3. Fora 9-inch girder rail 135 pounds of metal are used to formthe joint. It is claimed that by the use of the joints.
