STRENGTH OF CRATES TESTED BY TOSSING An important phase of the work of the timber mechanics department of the U.S. Forest Products Laboratory at Madison, Wis., has been to perfect the designing and nailing of these boxes so that their durability is greater. Chemically treated nails and reinforcement by diagonal braces have given more rigidity […]
