"My DEAR SIR:--On the other side is a copy of resolutions adopted at a consultation of the Senators from the Seceding States--in which Georgia, Alabama, Louisiana, Arkansas, Texas, Mississippi, and Florida were present. "The idea of the meeting was that the States should go out at once, and provide for the early organization of a Confederate Government, not later than 15th February. This time is allowed to enable Louisiana and Texas to participate. It seemed to be the opinion that if we left here, force, loan, and volunteer Bills might be passed, which would put Mr. Lincoln in immediate condition for hostilities; whereas, by remaining in our places until the 4th of March, it is thought we can keep the hands of Mr. Buchanan tied, and disable the Republicans from effecting any legislation which will strengthen the hands of the incoming Administration. "The resolutions will be sent by the delegation to the President of the Convention. I have not been able to find Mr. Mallory (his Senatorial colleague) this morning. Hawkins (Representative from Florida) is in Connecticut. I have therefore thought it best to send you this copy of the resolutions. "In haste, yours truly "D. L. YULEE. "JOSEPH FINEGAN, Esq., "'Sovereignty Convention,' Tallahassee, Fla." The resolutions "on the other side" of this letter, to which he refers, are as follows: "Resolved, 1--That in our opinion each of the Southern States should, as soon as may be, Secede from the Union. "Resolved, 2--That provision should be made for a Convention to organize a Confederacy of the Seceding States, the Convention to meet not later than the 15th of February, at the city of Montgomery, in the State of Alabama. "Resolved, That in view of the hostile legislation that is threatened against the Seceding States, and which may be consummated before the 4th of March, we ask instructions whether the delegations are to remain in Congress until that date for the purpose of defeating such legislation. "Resolved, That a committee be and are hereby appointed, consisting of Messrs. Davis, Slidell, and Mallory, to carry out the objects of this meeting." In giving this letter to the World--from its correspondent accompanying the expedition--the New York Times of March 15, 1862, made these forcible and clear-headed comments: "The telegraphic columns of the Times of January 7, 1861, contained the following Washington dispatch: 'The Southern Senators last night (January 5th) held a conference, and telegraphed to the Conventions of their respective States to advise immediate Secession.' Now, the present letter is a report by Mr. Yulee, who was present at this 'consultation' as he calls it, of the resolutions adopted on this occasion, transmitted to the said Finegan, who by the way, was a member of the 'Sovereign Convention' of Florida, then sitting in the town of Tallahassee.
