FIG. 23—DIBBLES, THEIR USE AND ABUSE a, flat'bladed, wide style; b, homemade "punch" dibbles; c, pot-plungine dibble; d, root-graft planting dibble; e, trowel style; f, dibble made from spade handle. A, right way to use dibble, when pressing soil from bottom of hole to top. B, wrong way—pressing soil from top and leaving air space around roots. or rainy season. Stratification consists in fully exposing the seeds to the action of the weather. The common practice is to place the seeds in shallow boxes in thin layers alternated with layers of sand or sifted soil. These boxes, covered with galvanized hardware cloth (one-half inch mesh) to keep out squirrels, mice and other crea- tures, are then placed flat on the ground out of doors so they will be moistened by rain and snow and will freeze and thaw as frequently as possible.
