Between the date of the letter to Harvey and March 7, Mr.Curtis says that the aspect of affairs had materially changed, and that the Union was in serious peril.

There is nothing to show that Mr.
Webster thought so, or that he had altered the opinion which he had expressed on February 14.

In fact, Mr.Curtis's view is the exact reverse of the true state of affairs.

If there was any real and immediate danger to the Union, it existed on February 14, and ceased immediately afterwards, on February 16, as Dr.Von Holst correctly says, when the House of Representatives laid on the table the resolution of Mr.Root of Ohio, prohibiting the extension of slavery to the territories.

By that vote, the victory was won by the slave-power, and the peril of speedy disunion vanished.
