USES AND ABUSES OF WATER ON FARM 47 CHAPTERS E have spoken somewhat of the action of y water in the soil and in the plant, but it will be well to look into this more closely. About four-fifths of the earth's surface is water, or per" haps we should say about one-fifth of our watery world is dry land, but this one-fifth is not very dry land. Water is in it everywhere. The soil is full of little pores, and water goes through all these and Spreads itself all over the surface of each little par- ticle. There is an ocean of earth-water constantly ebbing and flowing through the ground. This water is carried by capillary attraction through the earth in all directions. It goes downward, upward, and sideways, clinging to the surface of the porous subsoil. When dry hot weather comes and plant- growth calls for large quantities of water, capillary attraction helps to bring the water up from the deep subsoil. All the time it is carrying the water along.
