The downward ^ movement is much more rapid than the lateral movement, and both are very irregular, depending on the nature and structure of the soil. Ordinarily the furrows are relatively close together, to give greater uniformity in distribution. In corn, potatoes, berries, garden vegetables, and crops of similar character, a furrow is placed in each row, or at least in every other row as is 1 Widtsoe, J. A , and McLaughlin, W W.
