First. That no member of the association is allowed more than one vote because of the amount of stock or membership capital he may own therein; or
Second. That the association does not pay dividends on stock or membership capital in excess of 8 per centum per annum.
and in any case to the following:
Third. That the association shall not deal in the products of nonmembers to an amount greater in value than such as are handled by it for members.
