This day a Flag of Truce sent by Lord Howe to New York was stopped by the Rebels off Red Hook; it carried a letter for Mr. Washington, which was not received, as the Title was not thought honorable enough, being only directed to Geo: Washington, Esqr. Letters carried by another Flag to Amboy was received, but we know no further, or what was the intent of it. From appearances think the Rebels will not listen to any proffers for an Accomodation; their declaration of Independancy is a convincing proof that they will oppose every mode for a Reconciliation unless on their own terms.
