Nests on isolated trees may be safeguarded, but in the woods protection is hopeless, and hole-nesting birds, with the exception of chickadees, will rarely nest there. Nesting boxes hung by wires from outer branches of trees on the edge of the woods have given good results in some cases. Cats cannot reach these and squirrels seem not to trouble them often. (See Fig. 23.) Boxes placed ob poles set up in a pond or on a small island bring good results. Poles set on posts need not be over 6 or 8 feet in length, except for martins, and may be slim, made from young pines, cedars or other saplings. They may be screwed to fence posts with lag screws (large screws with square heads; see Fig. 24 and Plate VII, Fig. 2) so that they may be taken down in the fall and stored away until spring. (The barbed wire fence is best for this purpose as it is not used as a high- way by squirrels and cats.) Where there are no fences, posts may be set in the ground and the poles fastened to them.
