Even this conspiracy, thus supported and nurtured, would have been more wicked than strong, if it had not found perfidious aid in the very Cabinet of the President. The Secretary of the Treasury, a Slave-Master from Georgia, the Secretary of the Interior, a Slave-Master from Mississippi, the Secretary of War, the notorious Floyd, a Slave-Master from Virginia, and I fear also the Secretary of the Navy, who was a Northern man with Southern principles, lent their active exertions. Through these eminent functionaries the treason was organized and directed, while their important posts were prostituted to its infamy. Here again you see the extent of the conspiracy. Never before, in any country, was there a similar crime which embraced so many persons in the highest places of power, or took within its grasp so large a theatre of human action. Anticipating the election of Mr. Lincoln, the Cabinet conspirators prepared the way for rebellion. First, the army of the United States was so far dispersed and exiled, that the commander-in-chief found it difficult, during the recent anxious winter, to bring together a thousand troops for the defence of the national capital, menaced by the conspirators. Secondly, the navy was so far scattered or dismantled, that on the 4th of March, when the new Administration came into power, there were no ships to enforce the laws, collect the revenues, or protect the national property in the Rebel ports. Out of seventy-two vessels of war, counted as our navy, it appears that the whole available force at home was reduced to the steamer Brooklyn, carrying twenty-five guns, and the store-ship Relief, carrying two guns. Thirdly, the forts on the extensive Southern coast were so far abandoned by the public force, that the larger part, counting upwards of 1,200 cannon, and built at a cost of more than six million dollars, became at once an easy prey to the Rebels. Fourthly, national arms were transferred from Northern to Southern arsenals, so as to disarm the Free States and equip the Slave States. This was done on a large scale. Upwards of 115,000 arms, of the latest and most approved pattern, were transferred from the Springfield and Watervliet arsenals to different arsenals in the Slave States, where they were seized by the Rebels; and a quarter of a million percussion muskets were sold to various Slave States for $2.50 a musket, when they were worth, it is said, on an average, $12. Large quantities of cannon, mortars, powder, ball, and shell received the same direction. Fifthly, the National Treasury, so recently prosperous beyond example, was disorganized and plundered even to the verge of bankruptcy. Upwards of six millions are supposed to have been stolen, and much of this treasure doubtless went to help the work of Rebellion.
