M^-ERS SHAPE OF FIELDS The shape of farm fields Hkevvise has an important effect on the eco- nomical use of labor, fencing, and land. Effect of shape of fields on labor It is a fact commonly accepted that more time to the acre is required for performing farm operations in fields of irregular shape than in fields of regular shape. In order to determine the effect of this factor on the time required for plowing an acre, E. L. Baker kept a careful record- of the time required to plow fields of different shapes. The dimensions and shapes of the fields are indi- cated in figui'e 80. All conditions were made as uniform as possible. Small areas were takcMi in order to secure uniformity of soil and moisture conditions. All the fields were plowed by the same man and team. A part of a forenoon and a part of an afternoon were spent in plowing each field in order to obviate any diftei'ence in freshness of the team. A Wiard walking plow was used, turning a furi'ow 14 inches wide and 8 inches deep. Field A was plowt^d lengthwise, fis indicated by the arrows in the dia- gram. Field B, (>qual in size to field A, was plowxxl the short way. Field C was triangular in shape and was i)lowed the long way. The time i-equired to plow each field-and the rate of jilowing to the acre are shown in table 10. Altho fields A and B are of the same size, about 14 per cent more time was ]-equired to i)low field B. This was due to the shoi'tei- furrows and more frequent turns in field B, which wasted considerable time. It re- quired 22 per cent more time to plow the triangular field C than to ]:)low field A. Altho the average length of fm-rows in fields B and C are the same, seven per cent more time was required to plow field C. The Fig. S6.
