. Elements of Philippine agriculture. Agriculture. THE son. 19 Alluvial Soil. Most of the soil which moves from one place to another is carried by running water. Even the clearest creeks and ri\'ers always carry some of the land with them. When there are storms, a great deal of water runs from the land, and the soil carried with it makes the stream muddy. In the mountains, rivers run so rapidly that they can carry not only mud, but even large stones. When they reach more level land, where they flow more slowly, the stones are left. Lower down, where the water runs still more slowlv, it loses the '^rravel; and then the sand falls to the bottom. The finest par- ticles of the soil are carried on, and sink to the bottom of the still water at the rivers' mouths. In this way deltas are formed. Soil deposited from water is alluvial soil. Alluvial soil is usually fine and uniform. It is provided with all the foods of plants, and is easy to cultivate because it is level. The level land near Manila Bay, and almost all other level land in the Philippines, is 21. Stones in soil.
