My hon. friend says it is not control, but it is one kind of control. It is control of consumption. If we cut the sale of gasoline by twenty per cent we have saved that twenty per cent. I admit at once it is a crude way, but it is a quick way; it was adopted by the United States on the eastern seaboard and was adopted* in Canada to consolidate our gains. We wanted a reduction in gasoline consumption; we achieved it in that way; it has worked from the government point of view, but perhaps not so well from the point of view of the public.
Now we are working towards a rationing system for gasoline. In due course it will be necessary' to have a coupon book in order to obtain gasoline. Why have we not done it before? It is a very complex problem. First you have to determine the classification of users; then you have to decide the relative amounts that should be given to this and that user. It is not easy; it took England eighteen months to put her rationing system in operation.
