The moisture rising from below is not allowed to escape, but is checked in its upward course, just below this mulch. able depth. Plowing should not be of the same depth from year to year, for by so doing the soil is not mixed well and a hard surface is left at the bottom of the furrow where the horses walk and the plow drags. A little sub-soil turned to the surface occasionally will be acted upon by the atmospheric elements and plant food liberated. As it becomes mixed with the surface soil and vegetable growth, the depth of surface soil will be increased. A compact soil is less per- vious to air and moisture, and if organic matter is covered too deeply it will not decay for some time on that account. In general, to accom- plish the most desirable results, it is advisable to plow a little deeper each season for several successive seasons, and then for one season give a plowing at about half of the depth of the deepest plowing. It is well to have the farm mapped, the various fields numbered and records kept of the annual treatment and production of each field. Shallow plowing. Shallow plowing is not practiced in the fall '.u the corn belt, but is customary in the spring because the deeper the plowing the greater is the amount of labor required to re-establish the capillary connection wi
