_Passage by the Second House._--When a bill is passed by one house, it is signed by the presiding officer, after which it is transmitted to the other house, where it goes through practically the same stages of procedure as described above. If the bill is passed by the other house without amendment it is "enrolled," after which it is ready for the signature of the President. If, however, a bill as passed by one house is amended by the other, it is customary to appoint a conference committee, consisting usually of three members from each house, to discuss the differences and suggest a basis of compromise. The committee usually recommends that each house recede from its position on certain points, and the result is reported to each house, which usually accepts the agreement and the bill is passed. Many important bills are finally passed in this way, though occasionally the two houses fail to reach an agreement and the bill fails. _Approval of the President._--When the bill is presented to the President he is allowed ten days to make up his mind as to whether he will sign or disapprove it. If he refuses to sign it, he usually returns it to the house in which it originated, with a statement of his objections, after which the house must proceed to reconsider it, and if it is passed by a two-thirds vote it is sent to the other chamber and if repassed by it by a two-thirds vote it becomes a law notwithstanding the veto of the President. But in such cases the yeas and nays must be entered on the journal of each house so that the record may show that the bill was properly passed. In case the President does not approve the bill and neglects to return it within ten days to the house in which it originated, it becomes law in the same manner as if he had signed it, unless Congress should adjourn in the meantime so that it cannot be returned, in which case it does not become law. As a large number of bills are usually sent to the President during the last ten days of the session, an opportunity is thus afforded him for defeating bills by neither signing nor vetoing them. This method of defeating bills is popularly described by the term "pocket veto," a procedure sometimes resorted to where the President does not approve a bill and yet does not wish to take the responsibility for positively vetoing it. =Procedure in the Senate.=--In the senate, partly by reason of its small size, partly by reason of its permanence, and partly by reason of the tradition of senatorial courtesy, the procedure is somewhat different from that of the house of representatives. For example, the senate rules are permanent, that is, they continue from one Congress to another and do not have to be adopted anew every two years.
