The death of Taylor helped Clay's plans; for the soldier-President had discovered a strong vein of obstinacy. He had his own views on the question, and was by no means disposed to allow any Parliamentary leader to over-ride them. Filmore was quite content to be an instrument in the hands of a stronger man, and, after his succession, Clay had the advantage of the full support of the Executive in framing the lines of the last of his great compromises.
In the rough, those lines were as follows: California was to be admitted at once, and on her own terms, as a Free State, Arizona and New Mexico were to be open to Slavery if they should desire its introduction; their Territorial Governments, when formed, were to decide the question. This adjustment of territory was to be accompanied by two balancing measures dealing with two other troublesome problems which had been found productive of much friction and bitterness. The district of Columbia--that neutralized territory in which the city of Washington stood--having been carved out of two Slave States, was itself within the area of legalized Slavery. But it was more than that. It was what we are coming to call, in England, a "Labour Exchange." In fact, it was the principal slave mart of the South, and slave auctions were carried on at the very doors of the Capitol, to the disgust of many who were not violent in their opposition to Slavery as a domestic institution. To this scandal Clay proposed to put an end by abolishing the Slave Trade in the district of Columbia. Slavery was still to be lawful there, but the public sale and purchase of slaves was forbidden. In return for this concession to Anti-Slavery sentiment, a very large counter-concession was demanded. As has already been said, the Constitution had provided in general terms for the return of fugitive slaves who escaped from Slave States into the Free. But for reasons and in a fashion which it will be more convenient to examine in the next chapter, this provision of the Constitution had been virtually nullified by the domestic legislation of many Northern States. To put an end to this, Clay proposed a Fugitive Slave Law which imposed on the Federal Government the duty of recovering escaped slaves, and authorized the agents of that Government to do so without reference to the Courts or Legislature of the State in which the slave might be seized.
