The exemption throws the reader back to the definition of "agricul- tural products in the Co-operation Act. Recourse to that definition shows that it in turn refers to and depends upon the definition of " rural industry." However, combining these successive references, the material part of the exemption amounts to this :-It exempts from income tax the income of a rural society registered as such under the Co-operation Act, if the principal business of that rural society is the manufacture, treatment or disposal of the products of its members, being products of the cultivation or use of land for any (N.S.W.).
agricultural, pastoral, dairying, or rural purpose or of the livestock of its members.
The question appears to me to be whether the sale by the appellant of the butter manufactured by its members can properly be said to be the disposal of the products of its members, being products of the use of land for a dairying purpose.
In favour of an affirmative answer it is maintained that butter, whether factory-made or churned in a dairy, is by common under- standing the product of the use of land for a dairying purpose.
Butter is, of course, ordinarily included in the expressions dairy produce" and "dairy products" and these are often employed in common speech.
But the words occurring in the definition, namely, 'the product of the use of land for a dairying purpose," are descriptive and the description is specially constructed. It is not the mere adoption of a standing or constantly recurring expression. The definition expresses a condition in which "products of the cultivation or use of land seem to be the dominant words. The description of purpose, agricultural, pastoral, dairying or rural, imposes, of course, a further limiting condition, qualifying the use.
It is correct, I think, that we are to give the definitions of agricul- tural products" and of " rural industry" the same meaning as they bear and the same combined operation as they have standing in S. 5 of the Co-operation Act. It is also correct that if in the main provisions of that Act we find a context giving any guidance as to the meaning or application of such a phrase in the definition as
products of the use
of land we should refer to it and in interpreting the definition give the context as much effect for the purpose of the income tax exemption as for the purpose of the Co-operation Act.
But, even so, I think that the definition must be read as meaning to exclude from its application commodities in a manufactured form, like cheese and butter, when the manufacturing process is not part of the use of the land for the dairying, or, as the case may
