If I were five-and-twenty or thirty, instead of, unhappily, twice that number of years, I would take Adam Smith in hand—I would not go beyond him, I would have no politics in it—I would take Adam Smith in hand, and I would have a League for free trade in Land just as we had a League for free trade in Corn. You will find just the same authority in Adam Smith for the one as for the other; and if it were only taken up as it must be taken up to succeed, not as a political, revolutionary, Radical, Chartist notion, but taken up on politico-economic grounds, the agitation would be certain to succeed; and if you apply free trade in land and to labour too—that is, by getting rid of those abominable restrictions in your parish settlements, and the like—then, I say, the men who do that will have done for England probably more than we have been able to do by making free trade in corn.
