Stock should in all cases be excluded from the orchard. The low hedge is more attractive than the fence, and near towns is not so easy to climb. Another good reason for its use is that a low wind-break lessens evaporation by breaking the continuity of wind-sweep at the surface of the earth. A hedge eight feet in height of the Amur barberry at the north, or Osage or Cherokee rose at the south, does not affect the needed circulation of air, yet it will materially lessen surface wind-sweep and thus lessen evaporation. In different parts of Europe the low shelter-belts are used by seed-growers, nurserymen, and fruit-growers. An example of their value is shown in Manitoba, where many miles of shrubby Artemesia and other hedges have been planted to protect wheat-fields. Where the surface soil and even the seed wheat was blown away prior to their use little trouble is experienced at this time.
