In October 1869 the death of Lord Derby terminated the career of his son in the House of Commons, and the following year added very greatly to the happiness of his life by his marriage with the Dowager Marchioness of Salisbury. His attitude in opposition is clearly shown in his published speeches. He had no wish to see the Conservative party again in office till they possessed an assured and homogeneous majority, and he maintained that it should be their main object to strengthen the influence of the more moderate section in the Government. He believed that by habitually pursuing this policy they would best prevent revolutionary changes, mitigate by wise compromises measures which they did not wholly approve, secure the continuance of the harmony of classes, on which more than on any other condition the prosperity of England depends, and gradually strengthen their own hold on the confidence of the country. It was also his earnest desire that English politics should be turned as much as possible from a policy of organic change to a policy of administrative reform. He considered it a great evil that public men had acquired the habit of continually tampering with the existing legislative machinery instead of wisely using it for the benefit of the whole nation. The party system, as he always thought, had falsified the perspective of English politics, bringing into the foreground comparatively unimportant questions which were well suited to rally parties and win majorities; thrusting into the background others which were immeasurably more important, but which were less available for party purposes. What Carlyle called 'The Condition of England Question' was always in his thoughts. No one would accuse him of under-rating the evils of war, but he questioned whether the most sanguinary battle which had ever been fought carried off nearly as many human beings as die in England every year from purely preventible causes. He threw the whole force of his clear and penetrating intellect into such questions as sanitary reform, the regulation of mines, the promotion of education and especially technical education, the organisation of charities, the treatment of juvenile offenders, the diffusion of wise methods of encouraging saving among the poor. The overcrowding of the great cities, and the vast masses of insanitary dwellings, seemed to him one of the most pressing dangers of the time, and he was a prominent member of nearly every important company and association in England for improving the houses of artisans. He had no puritanism in his nature and was very anxious, by the establishment of free libraries and people's parks, and Sunday opening of museums, to extend the range of innocent pleasure. 'Men die,' he once said, 'for want of cheerfulness, as plants die for want of light.' He did not believe in the repression of drunkenness by coercive legislation like the Local Veto Bill, but he
