Physiognomies is usually thought of a doubtful technological know-how, yet is prac ticed on a daily basis in human conversation by way of every body from early adolescence to previous age. even if all of us may be able to figure the angrily furrowed forehead, the guffawing crow's-feet lower than the eyes, the smug harsh strains round the nostril, the difficult slender mouth, the gluttonous lip, and the key eye of the silent ob server, we might by no means admit to depend upon such likely uncertain methods.

Insufficiently repaired as it is, the wound will be inviting rot and insects for a long time. As is evident from its gigantic knots and awkward twists, the remaining left branch already must have been quite mature when induced by geotropism to place its centre over the butt. Nevertheless, it succeeded in situating the crown centre in good approximation over the ruthlessly incarcerated root centre. I A YOUNG BEECH BRAVING ADVERSITY This young, slender beech has grown toward the light from the very bottom of an extremely dark and dense stand.
Knowing that there will be no epinastic distance-demanding signals from the old, dead stem, and presupposing that the living branch win sooner or later be pushed upright by its own geotropism, one may wonder why the branch does not approach the old, dead stem any further. There are two possible reasons: First, the branch is at the southern side, and approaching tlie stem would mean growing into the shade. Second, the base of the branch has grown so thick that it is too stiff for further upright bending, and could not even bend if more reaction wood was formed there.
In the tree top, tension wood is formed first on the right- and then on the left-hand side of the stem to restore the vertical position. By sawing through the stem of a tree, one can determine the year of death of its leading shoot by the last of the tree rings of nearly circular shape. Once the shape of the tree is corrected, the widths of all subsequent tree rings are assumed to be equal again . Note that this does not necessarily imply roundness, but only equal thickness of the outermost tree ring .
