The greatest increase in appropriations of this class took place just after 1870. Since that date they have occupied a very prominent place in legislation, running from some twelve millions in the session of 1873-4 up and down through various figures to eighteen millions seven hundred thousand in the session of 1882-3, constituting during that decade the chief business of the Committee on Commerce, and finally having a special Standing Committee erected for their superintendence. They have thus culminated with the culmination of the protective tariff, and the so-called "American system" of protective tariffs and internal improvements has thus at last attained to its perfect work. The same prerogatives are accorded this new appropriations committee which have been secured to the greater Committee which deals with the estimates. Its reports may be made at any time when a member is not speaking, and stand in all respects upon the same footing as the bills proposing the annual grants. It is a special spending committee, with its own key to the Treasury. But the Appropriation Committees of the two Houses, though, strictly speaking, the only committees of supply, have their work increased and supplemented by the numerous Committees which devote time and energy to creating demands upon the Treasury. There is a pension list in the estimates for whose payment the Committee on Appropriations has to provide every year; but the Committee on Pensions is constantly manufacturing new claims upon the public revenues.[30] There must be money forthcoming to build the new ships called for by the report of the Committee on Naval Affairs, and to meet the charges for the army equipment and reforms recommended by the Committee on Military Affairs. There are innumerable fingers in the budget pie.
