Show Dew an Essential to Plants. The dlf.if 'v of lndif-- trass to flc .rlsh unuer n tree in fu.i loaf Is well known md Is generr'iy explained by saying that the tree absorbs tho nourishing c -stltuonts of the soil or that It keeps tho sunlight away from tho grass a-d protects It from tho rain. It Is doubtful whether nny of theBO explanations are true, the real reason roost probably b'.'.ng that tho vitalizing dew cannot form upon tho grass under a treo, whereas as a rule both rain and light can reach It. Dew Is probably essential to t'-e well-being of both plants nnd animals to a greater great-er extent than Is known. |
