A letter from commissioner Rost.--now conducted by Yankee publishing, the desire and request of , the following letter from commissioner Rost to Ron. W. L. Yancey:
Hotel d Yaglatersa, Adrid.Mr. Slidell's arrival in Paris, the weather was extremely cold. and my wife being in feeble health, I delayed my departure until the 18th of February I stopped on my way at Bordeaux, at the request of Captain Ruse, to see about getting some of his freight on board or a steamer fonding in that poor, and then went in the neighborhood to see one of my sisters, who had been seriously, ill; there my wife fell sick, and after a few days parted from her only way to Marsedies, where Brook the French steamer of the 5th March for Valencia. Mr. Fearn met me on the way. I arrived here on the 8th, and was well received unofficially; but as far as I can ascertain, there is truth in what was told me at the Spanish Legation in Paris, and also by M. Thouvenel, that Spain would not act alone on the American question. When you left, we did not expect that our Government would be recognized, but we had a well founded hope that the blockade would be set aside. You will no doubt, have seen that the declaration of Earl Russell that it could not be considered ineffective had been sustained in Parliament, and that a similar declaration of the French Minister had also been carried in the Chamber of Deputies by a large majority. This destroys the last to and that those Governments would do justice between the belligerents. Lieut be manifest to every one that we have to rely exclusively upon ourselves and to establish our independence After we succeed, we will owe the European Governments no thanks, and a war duty on imports sufficient to pay the interest of the debt which their course forces us to incur, and create a sinking fund, must be leveled. Coupled with the declaration that the blockade was not ineffective, Earl Russell made the statement, unsupported by any reason, that he trusted that by the first of or even before, the civil war would be ended. After reading in the President's inaugural that the war would probably conclude that the Earl gives faith to the assorduces of Mr. Seward that three months after the people of the Confederate States had become convinced that they had nothing to hope from England or France, the rebellion would end. The lest news of our reverses, exaggerated as they have been by the Northern press, have done great injury to our cause. When people hear of 15,000 men, strongly fortified, and made prisoners by an equal number of assailants, they begin to doubt the bravery of Southern troops and their ultimate success. Can you not, through Mr. Helm, or by some other channel, send us reliable Southern papers, exposing the falsehoods of the Northern press? Remember me to General Sparrow, Messrs. Semmes, Conrad, Perkins, Kenner, and Marshall, and believe me truly your friend.
P. S.--Present my respects to the President.
