Before further progress was made the House laid aside its bill in favor of the one which the Senate had now passed. An amendment to this, striking out the death penalty, was adopted on February 12 by a vote of 67 to 48. The North gave 31 ayes and 36 noes, quite evenly distributed among the states. The South cast 37 ayes to 11 noes, five of the latter coming from Virginia, two from North Carolina, and one each from Delaware, Maryland, Kentucky and South Carolina. A considerable shifting of votes appeared since the ballot on the same question six weeks before. Knight of Rhode Island, Sailly and Williams of New York, Helms of New Jersey and Wynns of North Carolina changed in favor of the extreme penalty; but they were more than offset by the opposite change of Bidwell of Massachusetts, Van Cortlandt of New York, Lambert of New Jersey, Clay and Gray of Virginia and McFarland of North Carolina. Numerous members from all quarters who voted on one of these roll-calls were silent at the other, and this variation also had a net result against the infliction of death. The House then filled the blank it had made in the bill by defining the offense as a high misdemeanor and providing a penalty of imprisonment of not less than five nor more than ten years. John Randolph opposed even this as excessive, but found himself unsupported. The House then struck out the prohibition of the coasting trade in slaves, and returned the bill as amended to the Senate. The latter concurred in all the changes except that as to the coastwise trade, and sent the bill back to the House.
John Randolph now led in the insistence that the House stand firm. If the bill should pass without the amendment, said he, the Southern people would set the law at defiance, and he himself would begin the violation of so unconstitutional an infringement of the rights of property. The House voted to insist upon its amendment, and sent the bill to conference where in compromise the prohibition as to the coastwise carriage of slaves for sale was made to apply only to vessels of less than forty tons burthen. The Senate agreed to this. In the House Mr. Early opposed it as improper in law and so easy of evasion that it would be perfectly futile for the prevention of smuggling from Florida. John Randolph said: “The provision of the bill touched the right of private property. He feared lest at a future period it might be made the pretext of universal emancipation. He had rather lose the bill, he had rather lose all the bills of the session, he had rather lose every bill passed since the establishment of the government, than agree to the provision contained in this slave bill. It went to blow up the Constitution in ruins."[30] Concurrence was carried, nevertheless, by a vote of 63 to 49, in which the North cast 51 ayes to 12 noes, and the South 12 ayes to 37 noes. The Southern ayes were four from Maryland, four from North Carolina, two from Tennessee, and one each from Virginia and Kentucky. The Northern noes were five from New York, two each from New Hampshire and Vermont, and one each from Massachusetts, Connecticut and Pennsylvania.
