Slavery, already looming up as a dominating issue, was the cause of two of the three great compromises that entered into the making of the Constitution of the United States (the third, which was the first made, being the concession to the smaller states of equal representation in the Senate). These were the first but not the last of the compromises that were to mark the history of the subject; and, as some clear-headed men of the time perceived, it would have been better and cheaper to settle the question at once on the high plane of right rather than to leave it indefinitely to the future. South Carolina, however, with able representation, largely controlled the thought of the convention, and she and Georgia made the most extreme demands, threatening not to accept the Constitution if there was not compliance with them. An important question was that of representation, the Southern states advocating representation according to numbers, slave and free, while the Northern states were in favor of the representation of free persons only. Williamson of North Carolina advocated the counting of three-fifths of the slaves, but this motion was at first defeated, and there was little real progress until Gouverneur Morris suggested that representation be according to the principle of wealth. Mason of Virginia pointed out practical difficulties which caused the resolution to be made to apply to direct taxation only, and in this form it began to be generally acceptable. By this time, however, the deeper feelings of the delegates on the subject of slavery had been stirred, and they began to speak plainly. Davie of North Carolina
