In compliance with the request of the Senate of yesterday’s date, I now communicate the entire correspondence between the Ambassador of Tunis and the Secretary of State, from which the Senate will see that, the first application by the Ambassador for restitution of the vessels taken in violation of blockade having been yielded to, the only remaining cause of difference brought forward by him is the requisition of a present of Naval stores to secure a peace for three years after which, the inference is obvious that, a renewal of the presents is to be expected to renew the prolongation of peace for another term. but this demand has been pressed in verbal conferences much more explicitly and pertinaciously than appears in the written correspondence. to save the delay of copying some originals are inclosed with a request that they be returned.
