O THE REPUBLICANS OF THE HOUSE OF EE PRE SENT ATT YES. Having been appointed against nay wishes, expressed both publicly and privately, by the Speaker as chairman of a committee to in¬ vestigate the state of affairs in the South, ordered to-day by Democratic votes against the most earnest protest of more than a two- thirds majority of the Republicans of the House, and certainly against the almost unanimous wish of the Republicans of the States whom it most specially concerns, my self-respect and deference to your good opin¬ ion requires me to explain to you, and through you to the country, why I shall not serve on "that committee—being convinced, as I am, that no good but harm only can come of it to the Republican party. First. Because this committee was forced upon the Republicans by the nearly unani¬ mous vote of the Democratic party in the House, aided by some twenty or thirty Re¬ publicans only, against the decision of the majority of that party in a duly called caucus of the members of the House. Second. Because this committee was raised by a combination of the high-tariff Republi¬ cans with the Democracy; the one class will¬ ing to permit the slaughter and extermina¬ tion of their political friends in the South if the tariff could be saved, even for nine months, by an early adjournment of Con¬ gress, and the Democracy acting with them in pursuance of a deliberate plan, carefully concocted, in my belief, to murder and out¬ rage enough Union men of the South to over¬ come, by fear, intimidation, and injury the Republican majority at the next Presidential election, well knowing that this committee can do them no harm, and that it will furnish an excuse to the tariff Republicans to vote with them for an early adjournment, without legislation to protect Union men in the rebel States. Third. Because such committee would be wholly powerless for any good purpose. Sit¬ ting in the vacation, it can have, under par¬ liamentary law, no power to compel the at¬ tendance of a single witness who does not choose to come, or an answer from one when he does come; as the only method by which any witness can be brought before a Con¬ gressional committee and made to answer when unwilling is, the House being in session, by its order of arrest, and imprisonment for his contempt during the session only; so that any unwilling witness can not be compelled to testify to anything; and the witnesses willingly coming before the commit¬ tee to testify anything against their Ku-klux neighbors would be killed on their way home from the committee room. I do not, there¬ fore, propose to make myself accessory be¬ fore the fact to the murder of every faithful Union man of the South who shall be brought before the committee and give truthful evi¬ dence of the state of outrage and wrong which I know to exist there. Fourth. Because my service as chairman of the committee would furnish the best electioneering document that could be placed in the hands of the Democracy in the com¬ ing contest, in this, that the report of the committee would be wholly nugatory, illu¬ sory, and useless to show the exact state of things at the South. Whenever and wherever the committee would go there would be sun¬ shine and peace, and we should be com¬ pelled so to l'eport. Where we were not and could not be, banded murder, robbery, arson, would stalk abroad at night, to be disbanded by the rising sun. Besides, I have not the slightest doubt that while serving on your committee in the Southern States I should be treated with the highest and most distinguished consideration and respect. That* would be in the farthest de¬ gree politic, and Southern men under¬ stand politics. 1 fully believe that I can go anywhere through every portion of the South, alone and unattended, and, a fortiori, when at the head of a Congressional committee of in¬ vestigation, without personal harm or in¬ sult. Therefore, when Republicans should claim in the canvass that it was necessary to maintain the Republican party in power to have peace at the South and protect our loyal friends there, they would be answered on every Democratic hustings, "You are not to be believed when you say that the laws can not be executed at the South and men's lives and property are in danger there, when you see that General Butler, the man who hanged one of these rebels' brethren; the man who brought New Orleans into subjection: the man who is more hated and vilified in the South than any other, can go through it untouched and unharmed." 1 have no intention of aid¬ ing the Democratic cause and breaking down the Republican party by furnishing in my own person any such argument with no countervailing good. Fifth. Because with these views of the ef¬ ficiency and powers of the committee, my ser¬ vices would be useless, and lam not accus¬ tomed to undertake to do that which I feel that I have no power successfully to accom¬ plish. And it is a parliamentary practice which has lately been illustrated in a signal instance in the Senate that the chairman of a committee should be in harmony with the majority who constitute it; and there is no element of harmony between me and that Democratic party, largely composed of Seces¬ sionists, old Whigs, and Know-nothings, who are the majority that constituted this com¬ mittee. Sixth. Because this committee was brought into being by a legislative trick—and not a creditable one at that—by which the wishes of the Republican majority of the House have been thwarted by a Republican minority, by the aid of Democratic votes, with which pro¬ ceeding, as a Republican, I desire most ef¬ fectually to divorce myself. Seventh. Because the very resolution which authorized the committee was so framed, and, in my belief, purposely, in the interests of the Democratic party, that such committee cannot report under the rules of the House in the face of the Democratic opposition, and, by their permission, in more than a year from this time, the usual power not being inserted in it, "to report at any time;" and being a special select committee, it cannot, under the rules of the House, be called in its turn until after all the standing committees have been called, which, in the last House of Rep¬ resentatives, took more than a year. So that, without the leave of the Democrats, such committee could not even make a report and have it printed until after the end of the next Presidential canvass. Eighth. Because the passage of the resolu¬ tion is a seeming discourtesy to the other branch of the Legislature; the Senate having taken up an investigation through its own committee, having proceeded to a very con¬ siderable extent in it, and made a report in part, which certainly to every Republican mind shows a state of crime and horror suffi¬ cient to justify legislative action. The House is made to say to the Senate, "You are not competent to perform the work you have undertaken; we will take it out* of your hands." I have no fear that you, my Re-publican friends, will think for a moment that any considerations looking to the labor and fatigue of such an undertaking in the heat of summer and the height of the yellow fever season in the Southern States, or the fact that I should be drawn from my home to carry on the investigation during those months, after laborious and arduous service here for more than four months, would deter me if I believed anv good could arise to the country from the labor or the exposure. I have spent more than one summer under a Southern sky to give what aid I could in pre¬ serving the life of the country; and if any good conld come of it, I would be quite will¬ ing to spend another, although when there before I was master of the rebellion within my reach and the scarcely less deadly and venomous'yellow fever. I am compelled to take this mode to ad¬ dress you in declining to serve, because the announcement of the committee was not made by the Speaker until after the vote of adjournment had been taken, and imme¬ diately thereupon his hammer fell, by which he adjourned the House, so as to preclude the possibility of resigning the place thus attempted to be forced upon me at the time. I believe I can demonstrate, even if a majority of a parliamentary body can force a Massachusetts man off a committee at plea¬ sure, that it is quite another thing for Ae Speaker to force another on a committee against his consent. 1 have the honor to be, very truly, your friend and servant, Benj. F. Butler.
