IMPORTANT FROM THE MEDITERRANEAN.

We have it from a source which is entitled to the fullest confidence, that in the early part of December, David Ofley, Esq. American Consul at Smyrna, proceeded to Constantinople, to negotiate a passage for the U.S. sloop of war Fairfield, Capt. Parker, to that city, having a gentleman on board who was the bearer of a Treaty to be entered into between the American Government and the Porte. Its purport was not known; but the importance attached to it by Commodore Crane, may be inferred from the fact, that, though in feeble health, he left his flag-ship and went on board, for the purpose of accompanying the embassy to Constantinople. On the 14th Dec. the Fairfield was at the mouth of the Dardanelles; and as soon as permission was received, would go up to the "famous city."

This explains the rumors which have been circulating through the English and French papers, relative to negotiations between the American Government and Turkey. One report says that the Porte were endeavoring to secure the co-operation of the American Navy in the war against Russia; and another, that the basis of the Treaty submitted by Mr. Olley, was the free navigation of the Dardanelles to all nations. These reports may be true: but we shall better know the nature and results of the Treaty, when they are officially announced. That a Treaty of some kind has been in the process of negotiation, is beyond a doubt.
