H(-avier soils rich in organic matter on the surface may be deepened quickly to advantage. Too much vegetable matter on top absorbs light rainfalls, keeping them at the surface, and no inducement is offered for the plant to root deeply. Shallow-rooted plants cannot withstand droughts and are dependent upon more continuous rains. It will thus be apparent that deep ploughing would be advantageous consistent with the keeping of a mellow surface. Ploughing should be performed in such a manner as to discourage the growth of weeds. Ploughs which do not invert the surface and cover young growing weeds are faulty and should not be used. Disc ploughs do not cover weeds as effectively as mould-board ploughs. For fallowing, ploughs which present the largest possible surface of the soil to the weathering agents should be used. kSmooth fallows also are invariably weedy ; rough surfaces should be aimed at. Smooth surfaces readily crust and run together after. Harvesting Wheat after being fed-off. heavy rains. Rough ones mellow and crumble down during the fallowing period, thereby continually changing the surface, which is desirable. Heavy storms run off smooth surfaces, whei'eas rough ones trap them. With mould- board ploughs the clods are kept on top when the land is ploughed dry, the finer particles settling beneath. The disc plough carries the fine particles to the top, sprinkling them as an impalpable dust over the surface. Such particles readily crust after heavy rains, and the fine condition of the surface induces the germination of the small seeds of weeds. Weeds.—Weeds should be attacked vigorously. They are robbers of plant- food and moisture. Heavy yields cannot possibly be obtained where they are abundant. Land should be ploughed as soon as p
