=Rules of Procedure.=--The Constitution provides that each house may frame its own rules of procedure, though it requires certain things to be done in the interest of publicity and to insure a reasonable degree of careful deliberation. Thus each house is required to keep and publish a journal which must show how motions are disposed of and the vote for and against measures voted on. It also requires that on demand of one fifth of the members present the yeas and nays upon a measure shall be entered upon the journal. The purpose of this provision is to enable a small number of members to put the house on record so that the people may know how their representatives have voted on important measures. _Filibustering._--This requirement serves a useful purpose, but it is sometimes taken advantage of by the minority in "filibustering," that is, in obstructing and delaying legislative proceedings. Thus a member may move to adjourn or to take a recess and ask that the roll be called and the yeas and nays on the question be entered upon the journal. If one fifth of the members join in the demand, the roll must be called and the process may be repeated indefinitely. On one occasion in the fiftieth Congress the house remained in session eight days and nights, during which time there were over one hundred roll calls on motions of this kind. _The Rules of the House of Representatives_ have evolved gradually out of the experience of the house during its long existence, and have come to be so complex and elaborate that they are really understood by only a few of the members, principally those who have had long experience in administering them. They have been revised from time to time, but except in a few particulars they are essentially what they were in 1880. They prescribe a certain order of business for each day's work, which, however, may be departed from by unanimous consent of all the members or by the adoption of a "special order" reported by the committee on rules.
