In the wood of many broad-leaved trees the wood fibresare much longer when full grown than when they are firstformed in the cambium or growing zone. This causesthe tips of each fibre to crowd in between the fibres aboveand below, and leads to an irregular interlacement of thesefibres, which adds to the toughness, but reduces the cleava-bility of the wood. At the juncture of the limb and stemthe fibres on the upper and lower sides of the limb behave GRAIN AND FIGURE IN WOOD ^ 89 differently.
