There are, indeed, two ways in which an ambitious young member of the House of Commons can render his services indispensable to the Prime Minister. He must, of course, first get the ear of the House, and make himself a power there. Then he may vote regularly with the party whips, support the leaders of his party on all occasions, and speak in their favour whenever he can be of use to them. In that case he is likely to be regarded as a promising young man of sound principles who can be relied upon by his chiefs. Or, he may follow the opposite course of the candid friend, criticising and even attacking the leader of his party, showing the weak points in his arguments, and the errors in his policy. In that case, if the young man has achieved so important a position that he cannot be disregarded, he stands a good chance of being given an office as a dangerous critic who must be conciliated and attached firmly to the government. The first of these methods is slower but safer. The second has sometimes been tried with startling success, notably in the case of Lord Randolph Churchill; but it has also been tried too obviously, and without the necessary social or parliamentary influence; and when it does not succeed it is likely to leave its victim hopelessly stranded below the gangway. [Sidenote: Increase in Size.] The number of members in the cabinet has varied very much at different times,[58:1] and of late years it has shown a marked tendency to increase. William Pitt had only six colleagues. A generation ago the cabinets contained from a dozen to sixteen members; but they have now run up to eighteen or twenty. There are several reasons for the change. In the first place, as the sphere of the state activity extends and the government grows more paternal, the range of affairs that come within the action of the cabinet is greater; and hence from time to time there is need of admitting a representative of some fresh department to its consultations. Then, on the political side, the development of the parliamentary system has made it necessary for the cabinet to have an ever stronger and stronger hold upon the House of Commons; and, therefore, the different shades of feeling in the party that has a majority in that House must be more and more fully represented in the cabinet. This alone would tend to increase the number of its members; but far more important still is the fact that a seat in the cabinet has become the ambition of all the prominent men in Parliament. Consequently the desire to be included is very great, and the disappointment correspondingly acute. For these various reasons there is a constant pressure to increase the size of the cabinet. The result is not without its evils. A score of men cannot discuss and agree on a policy with the same readiness as a dozen. There is more danger of delay when action must be taken. There is a greater probability of long discussions that are inconclusive or result in a weak compromise.
