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 § 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).
