Mr MENZIES (KOOYONG, VICTORIA) - It is entirely true that since the period of time at which the States levied their own income tax, that is to say since before uniform tax was established, there has been an acceptance by the Commonwealth Government, whatever side has been in office, of responsibilities on a large scale which were once treated as entirely within the domain of the States. To work out how far that has gone or what monetary value is to be attached to any of these matters is, of course, something I cannot do offhand. I will find out whether it is possible, without undue occupation of time within the department, to obtain that information. If it requires extensive analysis and research, I will have to consider whether it is worth while making the investigation.
