(a) Section 3(f) expressly provides that the term “agricultural or horticultural commodities” shall include the commodities defined as agricultural commodities in section 15(g) of the Agricultural Marketing Act, as amended (12 U.S.C. 1141-1141j). Section 15(g) of that Act provides: “As used in this act, the term ‘agricultural commodity’ includes, in addition to other agricultural commodities, crude gum (oleoresin) from a living tree, and the following products as processed by the original producers of the crude gum (oleoresin) from which derived: Gum spirits of turpentine, and gum resin, as defined in the Naval Stores Act, approved March 3, 1923” (7 U.S.C. 91-99). As defined in the Naval Stores Act, “ ‘gum spirits of turpentine’ means spirits of turpentine made from gum (oleoresin) from a living tree” and “ ‘gum rosin’ means rosin remaining after the distillation of gum spirits of turpentine.” The production of these commodities is therefore within the definition of “agriculture.”

(b) Since the only oleoresin included within section 15(g) of the Agricultural Marketing Act is that derived from a living tree, the production of oleoresin from stumps or any sources other than living trees is not within section 3(f). If turpentine or rosin is produced in any manner other than the processing of crude gum from living trees, as by digging up pine stumps and grinding them or by distilling the turpentine with steam from the oleoresin within or extracted from the wood, the production of the turpentine or rosin is not included in section 3(f).

(c) Similarly, the production of gum turpentine or gum rosin is not included when these are produced by anyone other than the original producer of the crude gum from which they are derived. Thus, if a producer of turpentine or rosin from oleoresin from living trees makes such products not only from oleoresin produced by him but also from oleoresin delivered to him by others, he is not producing a product defined as an agricultural commodity and employees engaged in his production operations are not agricultural employees. (For an explanation of the inclusion of the word “production” in section 3(f), see § 780.117(b).) It is to be noted, however, that the production of gum turpentine and gum rosin from crude gum (oleoresin) derived from a living tree is included within section 3(f) when performed at a central still for and on account of the producer of the crude gum. But where central stills buy the crude gum they process and are the owners of the gum turpentine and gum rosin that are derived from such crude gum and which they market for their own account, the production of such gum turpentine and gum rosin is not within section 3(f).
