Near the seacoast, or on mountains, or wherever trees are exposed daily to strong wind, they show by their bent forms and curi- ous shapes its potent influence (Fig. 201). The dying of the branches on the windward side (Fig. 202) is due to the drying effect of the wind, which may in- crease transpiration as much as twentyfold (see page 208). Even moist winds may have a drying effect. It is interesting to observe how the one-sided develop- ment of leaves and branches affects the stem. This is.
