THE ABOLITION INCENDIARIES.

Those two abolition incendiaries (Giddings and Hale) threw firebrands yesterday into the two houses of Congress.  The western abolitionist moved a resolution of inquiry into the transactions now passing in Washington, which brought on a fierce and fiery debate on the part of the southern members, in the course of which Mr. Giddings was compelled to confess, on the cross-questioning of Messrs. Venable and Haskell, that he had visited the three piratical kidnappers now confined in jail, and offered them counsel.  The reply of Mr. Toombs, of Georgia, was scorching to an intense degree.

The abolitionist John P. Hale threw a firebrand resolution into the Senate, calling for additional laws to compel this city to prevent riots.  This also gave rise to a long and excited debate.

No question was taken, in either house, before they adjourned.  But, in the progress of the discussion in both houses, some doctrines were uttered which are calculated to startle the friends of the Union.  Giddings justified the kidnappers, and contended that, though the act was legally forbidden, it was not morally wrong!  Mr. Toombs brought home the practical consequences of this doctrine to the member from Ohio in a most impressive manner.

Hale, of the Senate, whilst he was willing to protect the abolitionist, expressed himself willing to relax the laws and weaken the protection which is given to the slave property in this district!  Mr. Davis, of Massachusetts, held the strange doctrine, that while he would not disturb the rights of the slave-holders, he would not cease to discuss those rights!  As if Congress ought to discuss, or to protect a right to discuss, a domestic institution of the Southern States, with which they had no right to interfere!  Why discuss, when they cannot act?  Why first lay down an abstract principle, which they intend to violate in practice?

Such fanatics as Giddings and Hale are doing more mischief than they will be able to atone for.  Their incessant and impertinent intermeddling with the most delicate question in our social relations is creating the most indignant feelings in the community.  The fiery discussions they are exciting are calculated to provoke the very riots which they deprecate.  Let these madmen forbear, if they value the tranquillity of our country, and the stability of our Union.  We conjure them to forbear their maddened, parricidal hand.

An article like this in the Union was well calculated, and probably was intended, to encourage and stimulate the rioters, and accordingly they assembled that same evening in greater force than before threatening the destruction of the Era office.  The publication office of the Era was not far from the Patent Office; and the dwelling-house of Dr. Bailey, the editor, was at no great distance.  The mob,
