A ``farm'' is a tract of land devoted to the actual farming
activities included in the first part of section 3(f). Thus, the
gathering of wild plants in the woods for transplantation in a nursery
is not an operation performed ``on a farm.'' (For a further discussion,
see Sec. 780.207.) The total area of a tract operated as a unit for
farming purposes is included in the ``farm,'' irrespective of the fact
that some of this area may
not be utilized for actual farming operations (see NLRB v. Olaa Sugar
Co., 242 F. 2d 714; In re Princeville Canning Co., 14 WH Cases 641 and
762). It is immaterial whether a farm is situated in the city or in the
country. However, a place in a city where no primary farming operations
are performed is not a farm even if operated by a farmer (Mitchell v.
Huntsville Nurseries, 267 F. 2d 286).
