Abstract

The invention provides a method of treating timber. The method includes the step of immersing a sawn end of a freshly felled timber in a fluid having a viscosity suitable to permit drawing of the fluid through a part of a xylem capillary system of the timber as a result of a pressure differential existing between the sawn end and opposing end region of the freshly felled timber. The pressure differential may be caused by any one or combination of transpiration, photosynthesis and a suction induced by a vacuum pump connected to the opposing end region of the timber.
