“Transportation,” as used in section 13(b)(16), refers to the movement by any means of conveyance of fruits or vegetables from the farm to a place of first processing or first marketing in the same State. It includes only those activities which are immediately necessary to move the fruits or vegetables to the specified points and the return trips. Drivers, drivers' helpers, loaders, and checkers perform work which is exempt. Transportation ends with delivery at the receiving platform of the place to which the fruits or vegetables are transported. (Mitchell v. Budd, 350 U.S. 473.) Thus, unloading at the delivery point by employees who did not transport the commodities would not be a part of the transportation activities under section 13(b)(16).
