believed that its true root lay in overcrowding, ignorance, insanitary conditions of life, the want of innocent means of enjoyment, excessive hours of labour. 'When you have to deal with men in masses,' he said, 'the connection between vice and disease is very close. With a low average of popular health you will have a low average of national morality and probably also of national intellect. Drunkenness and vice of other kinds will flourish on such a soil, and you cannot get healthy brains to grow on unhealthy bodies. Cleanliness and self-respect grow together, and it is no paradox to affirm that you tend to purify men's thoughts and feelings when you purify the air they breathe.' He supported liberally the movement for establishing coffee-houses, and he looked with great hope to the co-operative movement as averting or mitigating industrial conflicts. 'The subject of co-operation,' he said, 'is in my judgment more important as regards the future of England than nine-tenths of those which are discussed in Parliament, and around which political controversies gather.' As the possessor of one of the largest properties in England he was excellently informed on all agricultural questions, and he exercised a great influence upon them. Among other services he dispelled many misrepresentations by obtaining an accurate return of the numbers of owners of land in the United Kingdom, and of the quantity of land which they owned. With the single exception of Lord Shaftesbury, I believe no conspicuous English public man devoted so much time and labour as Lord Derby to the class of questions I have described. He brought to their discussion an almost unrivalled fulness of knowledge. His purse was liberally opened in such causes, and the speeches in which he examined what Government can do and what it cannot do for the material well-being of the poor, are in my judgment among the most valuable contributions to political thought that have been furnished by any English statesman during the present century.
