building even to-day is greater than the benefit which would accrue from the unrating of improvements. The present is therefore the unique opportunity for bringing into force this much-needed reform in the most effective way, free from the difficulties which had to be met in 1913. If it had been carried out immediately after the Armistice it would, in my opinion, have done more than anything else to solve the housing problem, and even now it is not too late. In fact, in view of the present unemployment it would be most opportune. Incidentally it would soon render unnecessary the renewal of the Rent Restriction Act. I understand that something on these lines has been introduced in New York to meet a similar problem. A RATE AND A TAX UPON SITE VALUES The Committee of 1913 were obliged to turn their attention to other suggestions. They proposed: (_a_) That all future increases in the expenditure of each Local Authority which had to be met out of rates should be met by a rate upon site values instead of upon the existing assessments; and (_b_) That existing expenditure should be met to a small extent compulsorily, and to a larger extent at the option of the Local Authority, in the same manner. There is no reason why these proposals should not be brought into force simultaneously with that relating to new buildings and improvements. They made these proposals conditional upon a substantial increase in the grants in aid to Local Authorities, especially in necessitous areas, from the Imperial Exchequer; and they suggested, although they did not definitely recommend, that a part at least of this increased grant might be raised by means of an additional tax upon site values. This, I think, should certainly be done, and such a tax might be wholly or partially substituted for the present Land Tax and Income-Tax Schedule A, which are assessed on the wrong basis. These proposals would, of course, involve the revival and revision of the National Land Valuation established by the Finance Act, 1909-10, which should be made the basis of all taxation and rating relating to real property. This would be both a reform and an economy, because there are at present several overlapping systems of valuation by Central and Local Authorities, none of which are really satisfactory even on the present unsatisfactory basis of assessment. The existence of such a valuation frequently revised and kept up to date, and independent of local influences, would be invaluable not only for purposes of rating and taxation, but also in arriving at a fair price for the acquisition of land for public purposes, and for the levying of special charges upon the increased value due to particular public improvements, such as railway extensions, with which I have already dealt.
