The language of section 3(f) of the Act, in defining the
``secondary'' meaning of ``agriculture,'' provides that any practices
performed by a farmer or on a farm as an incident to or in conjunction
with such (his or its) farming operations are within the definition. The
practices which may be exempt as ``agriculture'' if so performed are
stated to include forestry or lumbering operations, preparation for
market, and delivery to storage or to market or to carriers for
transportation to market. The specification of these practices is
illustrative rather than limiting in nature. The broad language of the
definition clearly includes all practices thus performed and not merely
those named (see Maneja v. Waialua, 349 U.S. 254).
