to adhere, because, before that time, the Houses have not had the full opportunity of making replies to one another's arguments, and, to adhere so suddenly and unexpectedly, excludes all possibility of offering expedients.--4 _Hats._ 330. After a free conference the usage is to proceed with free conferences, and not to return again to a conference.--3 _Hats._ 270; 9 _Grey_, 229. After a conference denied, a free conference may be asked.--1 _Grey_, 45. When a conference is asked, the subject of it must be expressed, or the conference not agreed to.--_Ord. H. Com._ 89; 1 _Grey_, 425; 7 _Grey_, 31. They are sometimes asked to inquire concerning an offence or default of a member of the other House, 6 _Grey_, 181; 1 _Chand._ 304; or the failure of the other House to present to the King a bill passed by both Houses, 8 _Grey_, 302; or on information received, and relating to the safety of the nation, 10 _Grey_, 171, or when the methods of Parliament are thought by the one House to have been departed from by the other, a conference is asked to come to a right understanding thereon.--10 _Grey_, 148. So, when an unparliamentary message has been sent, instead of answering it, they ask a conference.--3 _Grey_, 155. Formerly, an address, or articles of impeachment, or a bill with amendments, or a vote of the House, or concurrence in a vote, or a message from the King, were sometimes communicated by way of conference.--7 _Grey_, 128, 300, 387; 7 _Grey_, 80; 8 _Grey_, 210, 255; 1 _Torbuck's Deb._ 278; 10 _Grey_, 293; 1 _Chandler_, 49, 287. But this is not modern practice.--8 _Grey_, 255. A conference has been asked after the first reading of a bill.--1 _Grey_, 194. This is a singular instance. During the time of a conference, the House can do no business. As soon as the names of the managers are called over, and they are gone to the conference, the Speaker leaves the chair, without any question, and resumes it in the return of the managers. It is the same while the managers of an impeachment are at the House of Lords.--4 _Hats._ 47, 209, 288. SECTION XLVII. MESSAGES. Messages between the Houses are to be sent only while both Houses are sitting.--3 _Hats._ 15. They are received during a debate, without adjourning the debate.--3 _Hats._ 22. $In Senate, the messengers are introduced in any state of business, except--1. While a question is putting. 2. While the yeas and nays are calling. 3. While the ballots are calling. The first case is short: the second and third are cases where any interruption might occasion errors difficult to be corrected.--So arranged, June 15th, 1798. In the House of Representatives, as in Parliament, if the House be in a committee when a messenger attends, the Speaker takes the chair to receive the message, and then quits it to return into a committee, without any question or interruption.--4 _Grey_, 226.$ Messengers are not saluted by the members, but by the Speaker, for the House.--2 _Grey_, 253, 274.
