Employees will not be held exempt under section 13(a)(13) unless
they are clearly shown to come within its terms. (Wirtz v. F. M. Sloan
Co., 4ll F. 2d 56 (C.A. 3), 18 WH Cases 878; Gatlin Lumber Co. v.
Mitchell, 287 F. 2d 76 (C.A. 5) cert. denied, 366 U.S. 963.) By its
terms, the exemption is limited to those employed in the named
operations by an employer who employs not more than eight employees
therein. The named operations are described in terms of ordinary speech
and mean what they mean in ordinary intercourse in this context. These
operations include the incidental activities normally performed by
persons employed in them, but do not include mill operations.
