Jay at this time, having been successively a member of the Continental Congress, the New York Legislature, and the State Constitutional Convention, having also been the first chief justice of his native state, and then president of the Continental Congress, had been sent as our minister to Spain. Morris always kept up an intimate correspondence with him. It is noticeable that the three great revolutionary statesmen from New York, Hamilton, Jay, and Morris, always kept on good terms, and always worked together; while the friendship between two, Jay and Morris, was very close.
The two men, in their correspondence, now and then touched on other than state matters. One of Jay's letters which deals with the education of his children would be most healthful reading for those Americans of the present day who send their children to be brought up abroad in Swiss schools, or English and German universities. He writes: "I think the youth of every free, civilized country should be educated in it, and not permitted to travel out of it until age has made them so cool and firm as to retain their national and moral impressions. American youth may possibly form proper and perhaps useful friendships in European seminaries, but I think not so _probably_ as among their fellow-citizens, with whom they are to grow up, whom it will be useful for them to know and be early known to, and with whom they are to be engaged in the business of active life.... I do not hesitate to prefer an American education." The longer Jay stayed away, the more devoted he became to America. He had a good, hearty, honest contempt for the miserable "cosmopolitanism" so much affected by the feebler folk of fashion. As he said he "could never become so far a citizen of the world as to view every part of it with equal regard," for "his affections were deep-rooted in America," and he always asserted that he had never seen anything in Europe to cause him to abate his prejudices in favor of his own land.
Jay had a very hard time at the Spanish court, which, he wrote Morris, had "little money, less wisdom, and no credit." Spain, although fighting England, was bitterly jealous of the United States, fearing most justly our aggressive spirit, and desiring to keep the lower Mississippi valley entirely under its own control. Jay, a statesman of intensely national spirit, was determined to push our boundaries as far westward as possible; he insisted on their reaching to the Mississippi, and on our having the right to navigate that stream. Morris did not agree with him, and on this subject, as has been already said, he for once showed less than his usual power of insight into the future. He wrote Jay that it was absurd to quarrel about a country inhabited only by red men, and to claim "a territory we cannot occupy, a navigation we cannot enjoy." He also ventured the curiously false prediction that, if the territory beyond the Alleghanies should ever be filled up, it would be by a population drawn from the whole world, not one hundredth part of it American, which would immediately become an independent and rival nation. However, he could not make Jay swerve a handsbreadth from his position about our western boundaries; though on every other point the two were in hearty accord.
