76 University of California Publications in History making war, in effect, on Spain, under the guise of scrupulous neu- trality, by supporting the insurgent colonies of Spanish America. Erving, according to the Bosquejo, came with full powers, but with a menacing tone, and with unjust demands. Onis, at the same time, had reported that the United States desired a boundary run- ning up the Rio Grande to the Thirty-first Parallel, and thence westward to the sea (though such a boundary determination could not have been based on official communications from the govern- ment at Washington). The best policy--so it had been decided when this sketch was written-would be to prolong the negotiation and to seek the aid of some respectable Power. Russia was favored. That nation was chosen because of her "direct interest" in seeing that the Spanish colonies were not freed, since, if they should be, the La Plata coun- try about Buenos Aires would undoubtedly take away Russia's trade in hides and tallow. It was also suggested that a territorial cession in the Floridas might be made to Russia, to recompense her for her aid and to provide a buffer against the United States. Rus- sia, as will be seen later, declined to aid Spain. Finally, the assertion was made in the Bosquejo that it was "urgent to keep the negotiation away from a diplomat as astute and turbulent as Erving," with the recommendation that Onis should negotiate the treaty. Onis was still fretting in Washington under the limited author- ity given him by Cevallos to make concessions to the United States. He was desperately afraid that if a settlement were not reached shortly this country would seize the Floridas and Texas, and would openly aid the revolting colonies. That the Spanish government also feared the latter eventuality is evident in the sketch quoted above outlining relations with the United States, on the success of which "depends in great part the fortune of our ultramarine colonies." MONBOE's LAST EFFORT AND NEW SPANISH PROPosALS Although Pizarro promised to send Onis further instructions at various times, none regarding the major issues at stake appears to have been sent until August, 1817, and no comprehensive set of instructions was forthcoming until November of that year. In the interim the minister to the United States was able to accomplish almost nothing.
