Brooks: Diplomacy and the Borderlands 85 cid6 was adopted, though Pizarro in his Memorias says he pre- ferred the first and second. Accordingly, in his note of August 17, 1817, already referred to, that minister offered Erving the project of a treaty. It was not accepted Apparently Pizarro's de- sign was not to submit an intentionally unacceptable plan, but he at least welcomed the resulting delay, which allowed him to sound out England and France. ONfs' NEw PROBLEMS Immediately upon the failure of Pizarro's approach to Erving, a session of the Consejo de Estado was held, from which resulted new instructions for Onis. They became the basis of his first dealings with Adams when he met the new secretary of state in Washington in December of that.year. The Consejo agreed, on August 27, that Onis should be instructed to advance at Washington essentially the same proposal made to Erving, that is, he was to offer the cession of the Floridas (contin- gent upon approval of England in accordance with the Treaty of Utrecht) in exchange for acceptance of the Mississippi as the west- ern limit of the United States." Simultaneously he was to suggest as an alternative an appeal to the good offices or mediation of two or more friendly Powers.

After they were sent, Ferdi- nand made certain notorious land grants in that area which would seriously have embarrassed the United States. Their validity be- came a major issue later between the two countries. However, the chronology of Spanish diplomacy at this time appears to convict
