If an employee is to be exempt under section 13(b)(14), he must be
employed by an ``establishment'' which is ``commonly recognized as a
country elevator.'' If he is employed by such an establishment, the fact
that it may be part of a larger enterprise which also engages in
activities that are not recognized as those of country elevators (see
Tobin v. Flour Mills, 185 F. 2d 596) would not make the exemption
inapplicable.
