The popular fury was further stimulated by the fact that from the territory included in the Louisiana purchase, three slave States had been added to the Union, and as yet only one free State; and that the solemn guaranty securing all the domain north of 36 deg.

30' was now to be trodden under foot when its operation was likely to prove hostile to slavery and favorable to freedom.

From the beginning of the government the slave-holding interest had secured the advantage in the number of States formed from territory added to the original Union.

The South had Louisiana, Arkansas, and Missouri out of the purchase from France in 1803, Florida from the purchase from Spain in 1819, and Texas, with its possibility of being divided into four additional States, from the annexation of 1845.

The North had only Iowa from the Louisiana purchase and California from the territory ceded by Mexico.
