Clause (B) of section 13(b)(16) exempts only those transportation
employees who are engaged in transportation ``of persons employed or to
be employed in the harvesting of fruits or vegetables.'' Transportation
of harvest workers is not exempt unless the workers are fruit and
vegetable harvest workers; transportation of workers employed or to be
employed in harvesting or other commodities is not exempt work under
section 13(b)(16). Wirtz v. Osceola Farms Co., 372 F. (2d) 584 (C.A.
5). Nor does the exemption apply to the transportation of persons for
the purpose of planting or cultivating any crop, whether or not it is a
fruit or a vegetable crop.
