weeds. Soils containing enough clay to make them retentive of moisture

the condition created by the plow and harrow, and often is the best
practice. There is some sacrifice of roots, but the gain far exceeds
the loss. It may be necessary to give a second such cultivation when a
clay soil is deficient in organic matter, but the root-pruning is a
