Parties are governed by certain natural laws. A party which adopts a principle at war with the sentiments of the people may succeed for a time by the force of party drill, but in the end it will go down. The CALHOUN doctrine destroyed a party. Under the operation of the same law the Democratic party has gone down. But you cannot destroy a party before its time. The effort of Virginia now is to overthrow the Republican party. The effort will not succeed. It is equivalent to an attempt to overthrow the country. I am not frightened at this idea of giving guarantees. I do not think them of much importance. I am willing to give such as are reasonable. We hold to a certain extent to your doctrine of State sovereignty, and would protect it. Our people North and South are too much alike in many respects. We are all inclined to stand too much upon party abstractions. This is almost the only reason why we cannot agree. We are told that some things stated here grate harshly upon the ears of gentlemen from the South. The converse of this is equally true. I can take a rebuke, I trust, in a good temper, but I do not like to be stabbed in the house of my friends. I do not like to have doctrines and opinions imputed to me and my party which are only entertained by a little knot of fanatical abolitionists in the neighborhood of Boston; a few men who will not vote under the present Constitution, and who are led and controlled by LLOYD GARRISON and WENDELL PHILLIPS. Mr. HOUSTON:--I am strongly averse to the introduction of the subject of party into the deliberations of the Conference. I did not intend to allude to party at all; but since the subject has been referred to in such impassioned terms, I feel that I must say a word about it. Many references have been made in this debate to the opinions of WASHINGTON. I wish his opinions were better observed and respected. I refer to his appeal to his countrymen not to form parties with reference to geographical lines, and asking them to frown indignantly upon every attempt to form such parties. What WASHINGTON foresaw, at length has come to pass. Parties have been formed, and are now in existence, divided by geographical lines, having no interests or opinions in common. But no such parties can long exist without threatening the stability of the Government. So long as parties were national in their character; so long as they excluded sectional interests from their platforms, their existence was a benefit rather than an injury to the Union. Gradually they have all drifted toward sectionalism, until now we find ourselves in a position which taxes the ability and ingenuity of the ablest men to provide for the existence even of our Government.
