In the case of mines and quarries, Parliament is especially responsible, because the possession of the mineral wealth of our country by private individuals is itself a gross usurpation of public rights, and should have been long ago declared illegal. Whatever arguments—and they are very strong—show us that the land itself should not be private property, are ten times stronger in the case of the minerals within its bowels. The value of land increases with its proper use, but in the case of minerals, the value is absolutely destroyed. Surely, it is a crime against posterity to allow the strictly limited mineral wealth of our country to be made private property, and very largely sold to foreigners, solely to increase the wealth of individuals and to the absolute impoverishment of ourselves and our children.[45:A] [45:A] I pointed this out forty years ago in an article entitled _Coal a National Trust_, which I republished twelve years ago in my _Studies, Scientific and Social_ (Vol. II., Chap. VIII.). I will here add one other argument which goes to the root of the matter by showing that the alleged owners of minerals have not even a legal title to them. It is, I believe, a maxim of law that public rights cannot be lost by disuse. Landed estates were, in our country, created by the Norman Conqueror to be held subject to the performance of feudal duties. Deep-seated minerals were then not known to exist, and were not (I believe) specifically included in the original grants. Except, therefore, where they have since been made private property by _Act of Parliament_, they still remain public property. I submit, therefore, that they may be both legally and equitably resumed by the Government as public property, and worked for the good of the public and of posterity. Compensation to the supposed present owners would be a matter of favour, _not of right_. CHAPTER IX INSANITARY DWELLINGS AND LIFE-DESTROYING TRADES The enormous difference between town and country dwellers as regards duration of life and the prevalence of zymotic diseases has been known statistically since the era of registration, and a body of Health Officers have been set up to report upon the worst cases. The local authorities have power to compel the owners of unhealthy dwellings to put them into a sanitary condition, or even order them to be entirely rebuilt. But as many of the members of Corporations and other Local Boards are often themselves owners of such property, or have intimate friends who are so, very little has been done to remedy the evil. Again and again, in all parts of the country, the Health Officers have duly reported, but their reports have been ignored. In some cases where the Health Officer has been too persistent, he has been asked to resign or has been discharged. A few general facts may be here given.
