DEAR SIR,--I wrote you last on the 11th; yesterday the bill for the _eventual_ army of thirty regiments (thirty thousand) and seventy-five thousand volunteers, passed the Senate. By an amendment, the President was authorized to use the volunteers for every purpose for which he can use militia, so that the militia are rendered completely useless. The friends of the bill acknowledged that the volunteers are a _militia_, and agreed that they might properly be called the "Presidential militia." They are not to go out of their State without their own consent. Consequently, all service out of the State is thrown on the constitutional militia, the Presidential militia being exempted from doing duty with them. Leblane, an agent from Desfourneaux of Guadaloupe, came in the Retaliation. You will see in the papers Desfourneaux's letter to the President, which will correct some immaterial circumstances of the statement in my last. You will see the truth of the main fact, that the vessel and crew were liberated without condition. Notwithstanding this, they have obliged Leblane to receive the French prisoners, and to admit, in the papers, the terms, "in _exchange_ for _prisoners_ taken from us," he denying at the same time that they consider them as _prisoners_, or had any idea of _exchange_. The object of his mission was not at all relative to that; but they choose to keep up the idea of a cartel, to prevent the transaction from being used as evidence of the sincerity of the French government towards a reconciliation. He came to assure us of a discontinuance of all irregularities in French privateers from Guadaloupe. He has been received very cavalierly. In the meantime, a _consul general_ is named to St. Domingo; who may be considered as our minister to Toussaint.
