A new process by which wood may be made as strong as mild steel was described by Mr J. F. Field, conservator of forests for Southland, in a talk to the Invercargill Rotary Club. If ordinary wood was soaked in a solution of urea (an inexpensive chemical) and was heated to a temperature of 210 degrees Fahrenheit it could be bent, twisted, compressed, and moulded. When it was again bone-dry and thoroughly cooled it was as strong as mild steel. This discovery, said Mr Field, would permit a wider- use of lowgrade timber. For instance, ureatreated-' wood might conceivably bo used instead of aluminium for aeroplane struts and ribs.
