This amounts to an enlargement, by so much, of the wound, and measures should be taken to prevent it. If the job lasts several days, the temporary edge of the opening should be shellacked if the danger is considered sufficient to warrant the trouble. When the edges have finally been shaped and pared smooth, the bast and cambium and the wood an inch below it should be painted with shellac or liquid wax. Such treatment will not only prevent drying but also the killing of the cambium by the antiseptic dressing.

BRACING

Bracing is next. Braces are put in to strengthen the tree, to make it more nearly rigid, in order that it may not crush the filling, to assist in the retention of the filling, and to prevent the opening up of cracks around its edges. For all these purposes it is almost futile to try to use braces which are entirely within the cavity. Such braces cannot be made stiff enough, and cannot be anchored strongly enough to the wood. The only way to do is to run the braces clean through from one side of the trunk to the other, which of course means that ordinary machine bolts are exactly
