At this time, and in the House of Representatives, was exhibited for the first time, the spectacle of members "pairing off," as the phrase was; that is to say, two members of opposite political parties agreeing to absent themselves from the duties of the House, without the consent of the House, and without deducting their per diem pay during the time of such voluntary absence. Such agreements were a clear breach of the rules of the House, a disregard of the constitution, and a practice open to the grossest abuses. An instance of the kind was avowed on the floor by one of the parties to the agreement, by giving as a reason for not voting that he had "paired off" with another member, whose affairs required him to go home. It was a strange annunciation, and called for rebuke; and there was a member present who had the spirit to administer it; and from whom it came with the greatest propriety on account of his age and dignity, and perfect attention to all his duties as a member, both in his attendance in the House and in the committee rooms. That member was Mr. John Quincy Adams, who immediately proposed to the House the adoption of this resolution: "Resolved, that the practice first openly avowed at the present session of Congress, of pairing off, involves, on the part of the members resorting to it, the violation of the constitution of the United States, of an express rule of this House, and of the duties of both parties in the transaction to their immediate constituents, to this House, and to their country." This resolve was placed on the calendar to take its turn, but not being reached during the session, was not voted upon. That was the first instance of this reprehensible practice, fifty years after the government had gone into operation; but since then it has become common, and even inveterate, and is carried to great length. Members pair off, and do as they please—either remain in the city, refusing to attend to any duty, or go off together to neighboring cities; or separate; one staying and one going; and the one that remains sometimes standing up in his place, and telling the Speaker of the House that he had paired off; and so refusing to vote. There is no justification for such conduct, and it becomes a facile way for shirking duty, and evading responsibility. If a member is under a necessity to go away the rules of the House require him to ask leave; and the journals of the early Congresses are full of such applications. If he is compelled to go, it is his misfortune, and should not be communicated to another. This writer had never seen an instance of it in the Senate during his thirty years of service there; but the practice has since penetrated that body; and "pairing off" has become as common in that House as in the other, in proportion to its numbers, and with an aggravation of the evil, as the absence of a senator is a loss to his State of half its weight. As a consequence, the two Houses are habitually found voting with deficient numbers—often to the extent of a third—often with a bare quorum.

In the first age of the government no member absented himself from the service of the House to which he belonged without first asking, and obtaining its leave; or, if called off suddenly, a colleague was engaged to state the circumstance to the House, and ask the leave. In the journals of the two Houses, for the first thirty years of the government, there is, in the index, a regular head for "absent without leave;" and, turning to the indicated page, every such name will be seen. That head in the index has disappeared in later times. I recollect no instance of leave asked since the last of the early members—the Macons, Randolphs, Rufus Kings, Samuel Smiths, and John Taylors of Caroline—disappeared from the halls of Congress.
